FCC Bans Sale Of
All Foreign Drones
In The U.S.
The FCC has
prohibited the sale
of all new
foreign-made drones
and drone components
in the U.S.,
ostensibly as a
matter of national
security. As FCC
Chairman Brendan
Carr said on X,
“Criminals,
terrorists, and
hostile foreign
actors have
intensified their
weaponization of
these technologies,
creating new and
serious threats to
our homeland.” It is
certainly true that
drones are
redefining the shape
of modern conflict.
But the question
here is, if foreign
drones get banned,
why wouldn’t all
these bad guys just
buy American drones
instead? It’s not
clear how the
prohibition solves
the purported
problem.
To be
clear, this ban only
affects any future
drone models
designed outside the
U.S. In
other words,
anything you can buy
right now will
continue to be on
sale. It’s just that
any newer models
will not be
certified, so going
forward, only old
foreign drones and
new domestic ones
will be available.
Take that,
terrorists! However,
the military and
homeland security
services can still
request waivers for
specific models they
want. And given that
many first
responders use
drones these days,
it wouldn’t be
surprising if they
get waivers, too.
ARRL The National
Association for
Amateur Radio® has
awarded a $5,000
Colvin Award grant
to the Delta-Xray
Group, organizers of
the upcoming 3YØK
DXpedition to Bouvet
Island, scheduled
for February and
March, 2026. Bouvet
is a remote island
in the Southern
Ocean, populated
only by seals and
penguins, and known
for treacherous
weather and surf
conditions. It is a
territory of Norway
and nearly all of it
is covered by
glaciers. The most
recent amateur radio
operation from
Bouvet was the 3YØJ
DXpedition in 2023,
which moved the
island from #2 on
the Club Log most
wanted list to #10.
Two camps are
planned, according
to team leaders,
operating all HF
bands, with one camp
focusing on high
band propagation to
North America when
conditions allow.
Each camp will
consist of three
tents serving as
operating, sleeping,
and communal spaces.
These tents have
previously been used
on Bouvet Island and
team leaders say
they have proven
capable of
withstanding the
extreme conditions
expected.
Plans call for
the team to leave
for Bouvet from Cape
Town, South Africa,
on February 1.
Weather permitting,
3YØK plans to use
helicopter airlifts
to transport
personnel and
equipment between
the vessel and the
island. The group
expects to spend
three weeks on and
around the island
and will attempt to
contact as many
other ham radio
operators around the
world as they can,
using up to 8
stations operating
on CW, SSB, FT8,
RTTY and the QO-100
geostationary
satellite.

Speaker Series
Explores WSPR
Spectral Width....
HamSCI‘s first
Speaker Series of
2026 will be
presented by Dr.
Barry Johnson (W4WB)
and focus on WSPR
spectral width.
[W4WB] will
be speaking on a
paper he
co-authored
along with Gene

titled “A Modest
Study of WSPR-2
Spectral Width”.
The topic arose
from a question
posed originally
by HamSCI
scientist Gwyn
Griffith G3ZIL
which was, “What
is the minimum
obtainable
spectral width
of WSPR-2
signals?” To
answer this
seemingly simple
question was
anything but
simple as will
become evident
in the
discussion
comprising this
presentation.
The presentation
will take place on
January 8th at 21:00

Reason versus
Sentimental
Attachment for Old
Projects
We have
probably all
been there:
digging through
boxes full of
old boards for
projects and
related parts.
Often it’s not
because we’re
interested in
the contents of
said box, but
because we found
ourselves
wondering why in
the name of
project
management we
have so many
boxes of various
descriptions
kicking about.
This is the
topic of[Joe
Barnard]’s
recent videoon
hisBPS.shortsYouTube
channel, as he
goes through box
after box of
stuff.
For some of
the ‘trash’ the
answer is pretty
simple; such as
the old rocket
that’s not too
complex and can
have its
electronics
removed and the
basic tube
tossed, which at
least will
reduce the
volume of
‘stuff’. Then
there are the
boxes with old
projects, each
of which are
tangible
reminders of
milestones,
setbacks,
friendships, and
so on.
Sentimental
stuff,
basically.
Some rules
exist for safety
that make at
least one part
obvious, and
that is that
every single
Li-ion battery
gets removed
when it’s not in
use, with said
battery stored
in its own
fire-resistant
box. That then
still leaves box
after box full
of parts and
components that
were ordered for
projects once,
but not fully
used up. Do you
keep all of it,
just in case it
will be needed
again Some Day?
The same issue
with boxes full
of expensive
cut-off cable,
rare and less
rare connectors,
etc.
One escape
clause is of
course that you
can always sell
things rather
than just
tossing it,
assuming it’s
valuable enough.
In the case of
[Joe] many have
watched his
videos and would
love to own a
piece of said
history, but
this is not an
option open to
most. Leaving
the question of
whether gritting
one’s teeth and
simply tossing
the ‘value-less’
sentimental
stuff and cheap
components is
the way to go.
Although
there is always
the option of
renting storage
somewhere, this
feels like a
cheat, and will
likely only
result in the
volume of
‘stuff’
expanding to
fill the void.
Ultimately [Joe]
is basically
begging his
viewers to help
him to solve
this conundrum,
even as many of
them and our own
captive audience
are likely
struggling with
a similar
problem. Where
is the path to
enlightenment
here?

The Cutting
Truth about Variable
Capacitors
If you’ve seen a big
air-variable
capacitor, you may
have noticed that
some of the plates
may have slots cut
into them. Why? [Mr
Carlson] hasthe
answerin
the video below. The
short answer: you
can bend the tabs
formed by the slots
to increase or
decrease the
capacitance by tiny
amounts for the
purpose of tuning.
For example, if you
have a radio
receiver with a
dial, you can adjust
the capacitor to
make certain spots
on the dial have an
exact frequency.
Obviously, you can
only adjust in bands
depending on how
many slots are in
the capacitor.
Sometimes the
adjustments aren’t
setting the
oscillator’s
frequency. For
example, the Delco
radio he shows uses
the capacitor to
peak the tuning at
the specified
frequency.
You usually only
find the slots on
the end plates and,
as you can see in
the video, not all
capacitors have the
slots. Of course,
bending the plates
with or without
slots will make
things change. Just
don’t bend enough to
short to an adjacent
plate or the fixed
plates when the
capacitor meshes.
A radio station
that played a
“pivotal role” in
the history of
wireless
communication is
celebrating its
125th anniversary.
The Lizard
Wireless Station in
Cornwall opened on 1
January 1901 and was
able to communicate
with ships up to 80
miles away, pushing
the boundaries of
what was thought
possible at the
time.
Later that same
month the station
received a wireless
signal from St
Catherine’s Point on
the Isle of Wight,
proving for the
first time radio
waves could follow
the curvature of the
Earth.
The National
Trust now cares for
the cliff-top
facility, operating
it as an amateur
radio station and
its historic call
sign will be active
for the whole of
January to mark the
anniversary.

Citizen Science
by the Skin of Your
Teeth
If you are a
schoolkid of the
right age, you can’t
wait to lose a baby
tooth. In many
cultures, there is a
ritual surrounding
it, like the tooth
fairy, a mouse who
trades your tooth
for a gift, or
burying the tooth
somewhere
significant. But in
1958, a husband and
wife team of
physicians wanted
children’s teeth for
a far different
purpose: quantifying
the effects of
nuclear weapons
testing on the human
body.
Louise and Eric
Reiss, along with
some other
scientists, worked
with Saint Louis
University and the
Washington School of
Dental Medicine to
collect and study
children’s discarded
teeth. They were
looking for
strontium-90, a
nasty byproduct of
above-ground nuclear
testing. Strontium
is similar enough to
calcium that
consuming it in
water and dairy
products will leave
the material in your
bones, including
your teeth.
The study took
place in the St.
Louis area, and the
results helped
convince John F.
Kennedy to sign the
Partial Nuclear Test
Ban Treaty.
They hoped to
gather 50,000 teeth
in a year. By 1970,
12 years later, they
had picked up over
320,000 donated
teeth. While a few
kids might have been
driven by scientific
altruism, it didn’t
hurt that the
program used
colorful posters and
promised each child
a button to mark
their participation.
Children’s teeth
were particularly
advantageous to use
because they are
growing and are
known to readily
absorb radioactive
material, which can
cause bone tumors.
Scale
You might wonder
just how much
nuclear material is
floating around due
to bombs. Obviously,
there were two bombs
set off during the
war, as well as the
test bombs required
to get to that
point. Between 1945
and 1980, there were
five countries
conducting
atmospheric tests at
thirteen sites. The
US, accounting for
about 65% of the
tests, the USSR, the
UK, France, and
China detonated 504
nuclear devices
equivalent to about
440 megatons of TNT.
Well over 500
bombs with
incredible force
have put a lot of
radioactive material
into the atmosphere.
That doesn’t count,
too, the underground
tests that were not
always completely
contained. For
example, there were
two detonations in
Mississippi where
the radiation was
contained until they
drilled holes for
instruments, leaving
contaminated soil on
the surface. Today,
sites like this have
“monuments”
explaining that you
shouldn’t dig in the
area.
Of course,
above-ground tests
are worse, with
fallout affecting
“downwinders” or
people who live
downwind of the test
site. There have
been more than one
case of people,
unaware of the test,
thinking the fallout
particles were “hot
snow” and playing in
it. Test explosions
have sent
radioactive material
into the
stratosphere. This
isn’t just a problem
for people living
near the test sites.
Results
By 1961, the team
published results
showing that
strontium-90 levels
in the teeth
increased depending
on when the child
was born. Children
born in 1963 had
levels of
strontium-90 fifty
times higher than
those born in 1950,
when there was very
little nuclear
testing.
The results were
part of the reason
that President
Kennedy agreed to an
international
partial test ban, as
you can see in the
Lincoln Presidential
Foundation video
below. You may find
it amazing that
people would plan
trips to watch
tests, and they were
even televised.
In 2001,
Washington
University found
85,000 of the teeth
stored away. This
allowed the
Radiation and Public
Health Project to
track 3,000 children
who were, by now,
adults, of course.
Sadly, 12
children who had
died from cancer
before age 50 had
baby teeth with
twice the levels of
the teeth of people
who were still alive
at age 50. To be
fair, the Nuclear
Regulatory
Commission has
questioned these
findings, saying the
study is flawed and
fails to account for
other risk factors.
And teeth don’t
just store
strontium. In the
1970s, other
researchers used
baby teeth to track
lead ingestion
levels. Baby teeth
have also played a
role in the Flint
Water scandal. In
South Africa, the
Tooth Fairy Project
monitored heavy
metal pollution in
children’s teeth,
too.
Morse code
lovers and navy
trainers help skill
live on in a world
of digital
technology
(Australia)
It may be an
antiquated form of
communication, but
many Australians
from all walks of
life are helping to
keep Morse code
alive.
Leo Nette calls
himself a proud
“Morsecodian” and
has been a long-time
volunteer at
Beechworth Telegraph
Station.
The station
opened in 1858 and
is the last one left
in operation in
Australia, albeit
using telephone
lines to transmit
messages now that
telegraph lines are
long gone.
Volunteers at
Beechworth Telegraph
Station work with Mr
Nette to receive
messages, type them
out and then post a
telegram through the
mail.
“Our oldest
[volunteer] is 95,
and our youngest is
in his early 70s, so
our future’s looking
grim,” Mr Nette
said.
With all of that
out of the way,
though, the setup is
able to track
hundreds of
satellites on very
little hardware, as
well as display
information about
each of them. We’d
always favor a build
that lets us gather
data like this
directly over using
something like a
satellite tracking
app, although those
do have their place.
And of course, with
slightly more
compute and a more
directed antenna
there is all kinds
of other data
beaming down that we
can listen in on as
well,although
that’s not always
the intent.
Build Yourself A
Graphing Weather
Display
These days,
Internet
connectivity is
ubiquitous, so you
can look up live
weather data on just
about any device
around you.
Regardless,
[Jozerworx] wanted a
simple, clean,
independent weather
display,and
came up with this
simple design.
The build is
based on the Lilygo
T5 EPD devboard,
which combines an
ESP32-S3
microcontroller with
a nice 4.7-inch
e-paper display.
This display has the
benefit that it only
uses power when it’s
being updated,
making it
particularly
suitable to run off
a battery for
extended periods of
time. Meanwhile, the
ESP32 and its
inbuilt Wi-Fi
connectivity allow
it to query the
internet for updated
weather forecasts.
Weather data is
sourced via the
OpenWeather API,
which [Jozerworx]
notes comes with the
caveat of requiring
an API key. It’s a
little fussy, but if
you want good
weather data, there
are few easier ways
to get it. The
display shows a
forecast for the
next five days,
while also showing
graphs of ambient
temperature and
humidity along with
useful information
like the sunset and
sunrise schedule.
Files areon
Githubfor
those eager to learn
more. [Jozerworx]
also notes that
getting started with
the display is
particularly easy
with the inclusion
of a setup mode.
This allows the
display to act as a
Wi-Fi access point
with a web page that
you use enter your
home Wi-Fi
connection details.

[Josh] aka [Ham
Radio Crash Course]
is demonstrating
this build on his
channel and showing
every step needed to
get something like
this working. The
first part is
finding the correct
LoRa module, which
will be the bulk of
the cost of this
project. Unlike
those used for most
Meshtastic nodes,
this one needs to be
built for the 433
MHz band. The
software running on
this module is fromTinyGS,which
we have featured
here before, and
which allows a quick
and easy setup to
listen in to these
types of satellites.
This build goes much
further into detail
on building the
antenna, though, and
also covers some
other ancillary
tasks like mounting
it somewhere
outdoors.
With all of that
out of the way,
though, the setup is
able to track
hundreds of
satellites on very
little hardware, as
well as display
information about
each of them. We’d

Lizard Wireless
Station celebrates
125 years of
world‑changing radio
history
The National
Trust is marking the
125th anniversary of
the Lizard Wireless
Station — the
clifftop site that
helped transform
global communication
— with a month of
special on‑air
activity and public
openings throughout
January.
The historic
building, perched
above the Atlantic
at Britain’s most
southerly point,
first opened on
January 1 1901,
becoming one of the
world’s earliest
commercial wireless
telegraphy stations
and enabling ships
up to 80 miles away
to communicate with
land for the first
time.
Just weeks later,
on January 23 1901,
the station achieved
a groundbreaking
feat: receiving a
wireless signal sent
from St Catherine’s
Point on the Isle of
Wight — conclusive
proof that radio
waves could follow
the curvature of the
Earth.
The breakthrough
paved the way for
Guglielmo Marconi’s
landmark
transatlantic
transmission from
Poldhu later that
same year,
establishing the
foundations of
long‑distance radio
communication.
Today, the site
remains a living
piece of radio
history. Cared for
by the National
Trust and run by
dedicated
volunteers, the
station still
operates as an
amateur radio hub,
connecting visitors
and radio
enthusiasts with the
very landscape where
pioneering
experiments once
took place.
During the
anniversary month,
the station’s
original call sign
will return to the
airwaves, and
visitors will be
welcomed inside for
rare
behind‑the‑scenes
tours.
Since 2017, the
station’s amateur
radio operations
have been overseen
by Geoff Bate, who
stepped into the
role after retiring
in 2016. Geoff, who
describes the
station as a unique
blend of 'location,
history and people,'
says meeting
visitors and sharing
its story remains
one of the
highlights of his
work.
His duties range
from equipment
maintenance to
managing access to
masts and aerials,
as well as helping
amateur radio
operators who travel
specifically to
broadcast from the
historic site.
Inside, one room
has been recreated
to show what the
equipment would have
looked like during
Marconi’s era, while
others display radio
artefacts and house
the modern amateur
station still in
active use.

If you work on
simple digital
projects, just about
any bench supply
will offer the
voltage and current
you’re looking for.
However, if you’re
working with valves,
you’ll often find
yourself needing
much higher voltages
that can be tricky
to source. [Chappy
Happy] has shared a
design fora
simple HV power
supplythat
should prove useful
to vacuum tube
enthusiasts.
The build is
fairly basic in
nature, lacing
together some
commonly available
parts to generate
the necessary
voltages for working
with common vacuum
tubes from a 12 volt
DC input. Inside the
supply is a UC3843A
DC boost converter,
set up to output
high voltage up to
around 300 volts DC,
with a ripple filter
added for good
measure. The output
can be adjusted with
a knob, with a
voltmeter on the
front panel. There’s
also a 12-volt
output, and a LM2596
step down converter
to produce 6.3 volts
for the filament
supply. The whole
project is built in
an old Heathkit
project box, and he
demonstrates the
supply with a simple
single-tube
amplifier.
If you find
yourself regularly
whipping up tube
circuits, you might
like to have

on your workbench.
Or, you might even
considercooking
up your own tubes
from scratchif
you’re more

Fessenden’s
message was
“One, two,
three, four. Is
it snowing where
you are, Mr.
Thiessen?”
Thiessen
responded,
“Yes.”
Fessenden
spent a few
years on Cobb
Island with his
associates and
built “all sorts
of various
contraptions”
until they
succeeded, Bob
Curran,
president of the
Charles County
Amateur Radio
Club, told
Southern
Maryland News.
“No one could
even talk on the
radio until he
figured out how
to do it,” he
said. “It
happened in our
backyard.”
Last week,
Curran set up a
TV transmitter
to send video
from Very House
to Fisherman’s
Field while
digital
communications,
the same way a
cellphone
“talks” to a
cellphone tower,
came from a
digital radio
model.
On the
digital radio
model at the
Very House, Bill
Luyster, a
member of the
Charles County
Amateur Radio
Club, made
contact with two
amateur radio
operators the
morning of the
event. Then
around 11 a.m.,
his computer lit
up red,
signifying
operators were
making contact
with him.
One of the
callers was from
Italy. Another
was from Russia
or Ukraine and
two were from
somewhere in the
United States,
according to the
local club
members.
A yellow bar
on the computer
is the
transmitter
Luyster uses to
contact
potential
callers and
green is when
operators call
“C-Q,” which is
when they call
any station that
is on the same
frequency and
sending digital
signals.
The club has
a QSL card, like
a postcard that
commemorates
events, that
callers receive
that include
information
about the radio
transmission
that can be used
to help them get
amateur radio
awards, Jeff
Humbert said. It
used to be the
only way to send
information, but
now it can be
sent through a
computer.
During
Fessenden’s
time, there were
only two houses
nearby, Pam
Humbert, member
of the Charles
County Amateur
Radio Club,
said.
Fessenden got
supplies from
Washington, D.C.
It was easily
accessible, but
still isolated.
“At the time
[it] was new
technology,” Pam
Humbert said.
“He wanted to
keep it secret
for a while.”
Fessenden
made it possible
for amateur
radio operators
to participate
in the club’s
events like
"Parks on the
Air," which
makes radio
contacts from
different state
national parks,
or operate their
own stations at
home.
“These are
the kind of
things amateurs
do to occupy
their time,”
Luyster said.
“It’s just a
hobby.”
In the words
of an amateur
radio operator:
“7-3.”
Or in plain
language: “thank
you, good bye.”
Any Old TV Can
Be A Clock With
Arduino
If you’ve got an
old black and white
TV, it’s probably
not useful for much.
There are precious
few analog
broadcasters left in
the world and black
and white isn’t that
fun to watch,
anyway. However,
with a little work,you
could repurpose that
old tube as a clock,
as [mircemk]
demonstrates.
The build is
based around an
Arduino Nano R3.
This isn’t a
particularly
powerful
microcontroller
board, but it’s good
enough to run the
classic TVOut
library. This
library lets you
generate composite
video on an Atmel
AVR microcontroller
with an absolute
minimum of
supporting
circuitry. [mircemk]
paired the Arduino
with a DS3231
real-time clock, and
whipped up code to
display the time and
date on the
composite video
output. He then also
demonstrates how to
hack the signal into
an old TV that
doesn’t have a
specific input for
composite signals.
You’ll note the
headline says “any
old TV can be a
clock,” and that’s
for good reason.
Newer TVs tend to
eschew the classic
composite video
input, so the TVOut
library won’t be any
good if you’re
trying to get a
display up on your
modern-era
flatscreen. In any
case,we’ve
seen the TVOut
library put to good
use before, too.

Art- K1BGH, a hell
of a nice guy,
talented too!
I was first
licensed in 1956 as
KN1BGH , took my
test from Bob Strid
W1RUU. Back in those
days the wheels of
the government spun
very slowly, It took
a long four months
to get my novice
license in the mail!
I ran 5 watts with a
home brew 6l6
oscillator and a
Hallicrafters Sky
Buddy and a folded
dipole abt 15 feet
off the ground. It
was magical, I would
race home from
school to get on the
radio! Turn the
tides of time
forward, After
spending 31 years
commercial
fishing, away from
home for a week at a
time, helping my
bride raise three
wonderful kids,
decided to retire
from fishing and
along with that
came the desire to
get back into ham
radio. I started
with the novice call
KA1COJ , then N1HPQ
as a general, KD1AL
as a Advanced then
got my old call back
K1BGH. Later got my
extra . Now enjoy
rag chewing with
friends on 75 meters
and enjoy working
dxon 80 meters .
Now in
semi-retirement
helping my bride
with her landscape
business and helping
my daughter-in law
with her seasonal
cafe and my seasonal
icecream shop and
keeping up to speed
with my five
grandchildren...Phew
Retirement !!!!
My other loves in my
life besides my
Bride, are our
Island Home on
Chebeague Island and
my passion about
Model A Fords. the
one I am working on
now is a 1931 hot
rod that was
neglected for years
it is now at a stage
where it is road

So Long Firefox,
Hello Vivaldi
It’s been
twenty-three years
since the day
Phoenix was
released, the web
browser that
eventually became
Firefox. I
downloaded it on the
first day and
installed it on my
trusty HP Omnibook
800 laptop, and
until this year I’ve
used it ever since.
Yet after all this
time, I’m ready to
abandon it for
another browser. In
the previous article
in this series I
went into my
concerns over the
direction being
taken by Mozilla
with respect to
their inclusion of
AI features and my
worries about
privacy in Firefox,
and I explained why
a plurality of
browser engines is
important for the
Web. Now it’s time
to follow me on my
search for a
replacement, and you
may be surprised by
one aspect of my
eventual choice.
Happily for my
own purposes, there
are a range of
Firefox alternatives
which fulfill my
browser needs
without AI cruft and
while allowing me to
be a little more at
peace with my data
security and
privacy. There’sChromiumof
course even if it’s
still way too close
to Google for my
liking, and there
are a host of
open-source WebKit
and Blink based
browsers too
numerous to name
here.
In the Gecko
world that should be
an easier jump for a
Firefox escapee
there are also
several choices, for
exampleLibreWolf,
andWaterfox.
In terms of other
browser engines
there’s the
extremely promising
but still early in
developmentLadybird,
and the more matureServo,
which though it is
available as a
no-frills browser,
bills itself as an
embedded browser
engine. I have not
considered some
other projects that
are either
lightweight browser
engines, or ones not
under significant
active development.
Over this summer
and autumn then I
have tried a huge
number of different
browsers. Every
month or so I build
the latest Ladybird
and Servo; while I
am hugely pleased to
see progress they’re
both still too buggy
for my purposes.
Servo is
lightning-fast but
sometimes likes to
get stuck in mobile
view, while Ladybird
is really showing
what it’s going to
be but remains for
now slow-as-treacle.
These are ones to
watch, and support.
I gave LibreWolf
and Waterfox the
most attention over
the summer, both of
which after the
experience I’d
describe as like
Firefox but with
mildly annoying
bugs. The inability
to video conference
reliably is a
show-stopper in my
line of work, and
since my eyesight is
no longer what it
once was I like my
browsers to remember
when I have zoomed
in on a tab.
Meanwhile Waterfox
on Android is a
great mobile
browser, right up
until it needs to
open a link in
another app, and
fails. I’m used to
the quirks of
open-source software
after 30+ years
experimenting with
Linux, but when it
comes to
productivity I can’t
let my software
disrupt the flow of
Hackaday articles.
It might surprise
you after all this
open-source
enthusiasm then, to
see the browser I’ve
ended up comfortable
with.Vivaldimay
be driven by the
open-source Blink
engine from Chromium
and Chrome, but its
proprietary front
end doesn’t have an
open-source licence.
It’s freeware, or
free-as-in-beer, and
I think the only
such software I use.
Why, I hear you ask?
It’s an effort to
produce a browser
like Opera used to
be in the old days,
it’s European which
is a significant
consideration when
it comes to data
protection law, and
it has (so far)
maintained a
commitment to
privacy while not
being evil in the
Google motto sense.
It’s quick, I
like its interface
once the garish
coloured default
theme has been
turned off, and
above all, it Just
Works. I have my
browser back, and I
can get on with
writing. Should they
turn evil I can dump
them without a
second thought, and
hope by then
Ladybird has matured
enough to suit my
needs.
It may not be a
trend many of us
particularly like,
but here in 2025
there’s a sense that
the browser has
reduced our
computers almost to
the status of a
terminal. It’s thus
perhaps the most
important piece of
software on the
device, and in that
light I hope you can
understand some of
the concerns
levelled in this
series. If you’re
reading this from
Firefox HQ I’d
implore you to
follow my advice and
go back to what made
Firefox so great
back in the day, but
for the rest of you
I’d like to canvass
your views on my
choice of a worthy
replacement. As
always, the comments
are waiting.
Amateur Radio
Newsline Report
SUCCESS WITH STUDENT
DMR PROJECT IN INDIA
STEPHEN/ANCHOR: Our
top story takes us
to India. Exactly
one year ago, ham
radio stations were
established in 20
residential schools
in disadvantaged
areas of one
southwestern state.
A year later,
teachers and their
students have become
a small, thriving
amateur radio
community thanks to
these small digital
mobile radios, or
DMR. John Williams
VK4JJW has that
update.
JOHN: The challenge
of teaching science
and communication to
disadvantaged
students in the
Indian state of
Karnataka got a big
boost one year ago
when the Karnataka
Residential
Educational
Institutions Society
turned 20 of its
schools into ham
shacks. Some of the
teachers became hams
and, in turn, guided
their young students
in grades 6 through
12 along the way.
Forty students
became hams and were
soon using the DMR
hand-held radios,
participating in the
daily net and
connecting to the
world.
More broadly, with
the installation of
DMR base stations by
the Indian Institute
of Hams, the schools
themselves became
communication hubs
that could be used
when natural
disasters knocked
out conventional
means of contact in
their remote rural
communities.
The past year has
been one of
challenge and
innovation for
Shirin, VU3DBO, one
of the 20 teachers
in the school system
who received her ham
radio certificate
from the Ministry of
Communication. The
science teacher wove
the radio curriculum
into the classes
where she also
taught about energy,
technology, the
environment and
space.
Shirin told Newsline
in an email that the
hands-on STEM
learning, the
expanded
communication skills
and the exposure to
team work has
sparked the
students' curiosity
and built confidence
over the past year.
She said amateur
radio was [quote] "a
wonderful hobby, fun
in a hands-on way."

UNIVERSAL POSTAL
CONGRESS ENDS USE OF
IRCS in 2026
STEPHEN/ANCHOR: Say
goodbye to IRCs, the
coupons that are
still in use in
parts of the world
by hams requesting
QSL cards. Next year
at this time they'll
be gone, as we hear
from Graham Kemp
VK4BB.
GRAHAM: Although
International Reply
Coupons, or IRCs,
are still being used
by some DX-chasing
hams in their
requests for QSL
cards, that option
is set to end by
this time next year.
Countries belonging
to the Universal
Postal Union have
voted to discontinue
their use effective
31 December 2026.
The vote was taken
in September at the
28th Universal
Postal Congress held
in Dubai. There are
a number of IRCs
already in
circulation that
bear the expiration
date of 31 December
2025 and they are
expected to be
honoured for another
year.
In an era marked by
a migration toward
confirmations on
digital platforms
and in digital QSOs,
the move brings an
already disappearing
amateur radio
practice to its
conclusion. A
statement from the
Universal Postal
Union said the
sunset of the IRC,
first put into
practice in 1907,
was [quote] “a
natural progression
within the broader
transformation of
international postal
services in
alignment with the
digital practices
and modern outlook
of their customers.”

SILENT KEY: JIM
SHAFFER, KE5AL,
ADVOCATE FOR BLIND
HAMS
STEPHEN/ANCHOR: An
advocate for hams
who are blind and
for the Handiham
program that serves
amateur radio
operators with
disabilities has
become a Silent Key.
We hear about him
from Travis Lisk
N3ILS.
TRAVIS: The amateur
radio software
developed by Jim
Shaffer, KE5AL, gave
hams who are blind
the ability to
control and monitor
their HF rigs
without needing a
sighted person's
assistance,
providing the
freedom of
independent
operating in their
shacks. The retired
IBM software
engineer knew that
operating challenge
all too well: he was
blind since birth.
Jim became a Silent
Key on the 2nd of
December. According
to his online
obituary, the Texas
resident died of
complications from
Parkinson's disease.
Jim's well-known
applications,
JJRadio and JJ Flex
Radio, attracted
attention for their
promise of
accessibility when
used with many
different radio
models. His
development of the
free programs
brought him to the
attention of host
Hap Holly/KC9RP,
host of the RAIN
Report, which
featured an
interview with Jim.
Hap, who became a
Silent Key earlier
this year, had also
been blind since
birth -- and like
Jim, also supported
the Handiham progam,
which trains and
serves the community
of hams with
disabilities.
Non-hams in Central
Texas also knew Jim
well for his other
deep involvement: He
was a versatile
musician and popular
fiddler in a number
of music groups,
including the Piney
Grove Ramblers.
Jim was 72.

SILENT KEY: JIM
HEATH, W6LG, NOTED
YOUTUBE ELMER
STEPHEN/ANCHOR: The
host of a popular
YouTube Channel that
made him the Elmer
to nearly 53,000
subscribers and
viewers has become a
Silent Key. We hear
about him from Paul
Braun WD9GCO.
PAUL: In many of the
videos on his
channel, Jim Heath
W6LG, introduces
himself as "your
YouTube Elmer for
ham radio basics."
In his easygoing,
personable style,
Jim explained, in
plain and basic
language, the
mysteries of SWR,
grounding, antennas
and dummy loads. A
popular presence on
YouTube, Jim brought
viewers directly
into his radio room
via a YouTube studio
inside his shack.
Jim, who had endured
years of
hospitalizations
following a leukemia
diagnosis, became a
Silent Key on
December 22nd at his
California home. He
had been a ham since
getting his license
in 1964 with the
callsign WN6JZC. He
had held his
well-known vanity
callsign, W6LG,
since 2004. He also
grew to love chasing
DX and counted among
his collection the
QSL cards of King
Hussein of Jordan
JY1 and Father
Marshall D. Moran
9N1MM, the first ham
radio operator in
Nepal.
Jim had also been
the owner of High
Sierra, which made
one of the first
screwdriver antennas
for mobile HF use.
Over much of his
adult life, Jim
faced numerous
health challenges --
a disabling fall
from a roof in 1998
while working as a
building inspector;
and a series of
health crises later,
including pulmonary
embolisms,
congestive heart
failure and severe
osteoporosis. Then
came the news he had
leukemia.
In his final months
he appeared on Ham
Smarter, the YouTube
channel of Vince
D'Eon VE6LK, and the
two became friends.
Vince described Jim
as [quote] "a good
friend to many and
an Elmer to all."
Announcing Jim's
death, Vince urged
hams to continue
visiting the W6LG
channel so they can
[quote] "learn from
the best."
[endquote]
Jim was in his
mid-70’s.

MINNESOTA HAM TEAM
KEEPS HOLIDAY FEST
SAFE AND BRIGHT
STEPHEN/ANCHOR: The
sudden assembly of
thousands of people
in one small, rural
16-block-long
Minnesota town in
early December
spurred swift and
careful action from
first-responders and
amateur radio
operators - but this
was no community in
crisis; it was a
celebration. Kent
Peterson KCØDGY
explains.
KENT: The small town
of Arlington,
Minnesota is always
happy to welcome
newcomers,
particularly at its
annual holiday
festival,
Arli-Dazzle. No
doubt there were
first-timers among
those attending in
the estimated crowd
size of 10,000 who
arrived on December
5th and 6th, feeling
the holiday spirit.
Perhaps more
importantly, the
newcomers included
10 ham radio
operators - six of
them newly licensed
Technicians, with
handy-talkies in
hand - as part of
the team of more
than 34 hams who
volunteered to
ensure that everyone
enjoyed this holiday
tradition.
Don Burgess, KCØQNA,
the emergency radio
coordinator for
Sibley County, told
Newsline in an
email: [quote] “This
town event is one
that a lot of my
radio team really
looks forward to
doing each year
regardless of temps
or weather
conditions. The
Local Police Chief
looks to us as his
reserve officers in
many aspects, and we
never let him or the
community down.”
[endquote]
He said the hams
traveled from as far
away as Minneapolis
and St. Paul - the
so-called “Twin
Cities” an hour away
- to make sure
things went
smoothly, from
setting up
barricades for the
5K runners to
setting up light
generators for the
parade route. The
Sibley Emergency
Radio Team Club,
with Don as safety
and logistics
coordinator, have
provided that
reassuring presence
for the past 16
years.
The team is no
stranger to
community service at
dozens of public
events - even in
nearby towns such as
Gaylord. This
festival is one
that’s special, said
Don. [Quote] “It
really takes on the
mom and pop old days
family Christmas
vibes for sure.”
[Endquote] The team
is happy to lend mom
and pop a hand.

RAY SOIFER W2RS/SK
HONORED AGAIN IN
AMSAT CW EVENT
STEPHEN/ANCHOR: The
new year brings an
opportunity to honor
the memory of a
satellite enthusiast
who left the lasting
legacy of a popular
CW event. We have
those details from
Randy Sly W4XJ.
RANDY: Ray Soifer,
W2RS, loved CW and
he also loved
satellites. Before
becoming a Silent
Key in March of
2022, Ray gave a
gift to both the CW
and satellite
communities: AMSAT's
CW Activity Day,
formerly known as
AMSAT Straight Key
Night.
The annual event has
since been renamed
the W2RS Memorial
AMSAT CW Activity
Day and, as always,
the on-air action is
taking place on
January 1st, the
same day that the
ARRL holds Straight
Key Night.
Participants use any
amateur radio
multi-mode satellite
to make QSOs using
CW on that day
between 0000 and
2359 UTC. Although
the use of a
straight key or a
bug is not required,
it is strongly
encouraged. So are
photos and video
clips, which
operators are
invited to share on
various social media
platforms with amsat
as the tag. As for
logs, they're not
necessary either,
but AMSAT would like
operators to submit
reports to the
AMSAT-BB.
One word of caution:
operators are urged
to use the minimum
power necessary to
complete their
contacts. Constant
carrier modes such
as CW are capable of
disrupting
transponders.

KICKER: NO TIME LIKE
THE PRESENT ...
MAYBE
STEPHEN/ANCHOR: With
the old year ending,
and a new year
starting up, it
might seem to some
of us that time is
out of sorts. Well,
it actually WAS out
of sorts here in the
US - in Boulder,
Colorado, home of
the F-4 atomic clock
that delivers the
official time with
precision, right
down to the
microseconds. Kent
Peterson KCØDGY
explains.
KENT: A
storm-related power
cut by the electric
utility serving the
Boulder campus of
the National
Institute of
Standards and
Technology caused a
drift in time of 4
millionths of a
second in the
official
time-keeper, the F-4
atomic clock. Those
moments are
immeasurable and of
little importance to
most of us - except
for those who rely
on precision in data
centers, global
positioning systems,
aerospace,
telecommunications
and the Network Time
Protocol service,
the timing resource
for computer
systems.
In the wake of the
storm, Jeff Sherman,
the physicist who
maintains the atomic
clocks, reported in
a mailing-list post
on Google groups
that [quote]: "The
atomic ensemble time
scale at our Boulder
campus has failed
due to a prolonged
utility power
outage." [endquote]
By some reports,
then, in late
December, time
literally stood
still -- however
briefly -- until the
switch was made to a
backup generator.
That cost the F-4
atomic clock its
accuracy.
Anticipating the
storm with winds of
hurricane strength,
the NIST had
previously advised
users to connect to
redundant systems at
other campuses such
as WWV/Fort Collins
Colorado, or
Gaithersburg,
Maryland which would
remain unaffected.
As for the F-4
atomic clock in
Boulder, the time
discrepancy was
resolved with the
clock's
recalibration after
power was back on by
Sunday, December
21st. It was, of
course, just a
matter of time.

Waldoboro is
centrally located
along the pristine
coast of Lincoln
County, Maine.
Incorporated in
1773, it soon
developed a
reputation as a ship
building and port
facility from the
banks of the scenic
Medomak River. The
town's strong
agricultural and
fishing legacy
continues today.
Waldoboro is
consistently the
largest soft-shell
clam landing in the
State of Maine. Our
farming heritage has
been renewed by
enthusiasm for
traditional natural
fiber production,
cheesemaking, farm
brewing,
fermentation,
soapmaking, and
other lost agrarian
arts. Waldoboro is
becoming a popular
destination with
miles of beautiful
river frontage, a
thriving arts
community, and a
vast historical
interest in its past
as a German
settlement. From
the shores of our
pristine Medomak
River to our farms
come home to
Waldoboro!
The first step
was to make the
holographic segment
displays, because
they’re not really
something you can
just buy off the
shelf. [mosivers]
achieved this by
using a kit from
LitiHolo, which
enables you to
create holograms by
shooting a laser at
special holographic
film. Only, a few
upgrades were made
to use the kit with
a nicer red diode
laser that
[mosivers] had on
hand for better
performance. The
seven-segment
layouts were
carefully recorded
on to the film to
form the basic
numerals of the
clock, such that
illuminating the
films from different
angles would light
different segments
of the numeral. It’s
quite involved, but
it’s explained well
in the build video.
As for the
timekeeping side of
things, an ESP32 was
used, setup to query
a network time
server to stay
accurate. The
microcontroller then
commands a series of
LEDs to light up as
needed to illuminate
the relevant
segments of the
holographic film to
show the time.
Ultimately,
[mosivers] built a
cool clock with a
look you won’t find
anywhere else. It’s
a lot more work than
just wiring up some
classic
seven-segment LEDs,
but we think the
result is worth it.
If you fancy other
weird seven-segment
builds, though,we’ve
got plenty of others
in the till.

How Israel’s
amateur radio
operators used quiet
diplomacy, saved
lives on Oct. 7 –
opinion
In a world where
trust has become
a scarce
resource,
amateur radio
operators offer
something
different: human
communication
that connects
people around
the world who
share the same
passion.
In a
digital age
in which
screens
shape
reality and
algorithms
steer public
opinion,
there exists
another
arena, quiet
and largely
unnoticed,
where a very
different
kind of
communication
takes place.
It is a
world in
which
private
individuals,
enthusiasts,
connect
countries,
break down
barriers and
build
bridges that
at times
precede
official
policy.
Many are
unaware of
the depth of
the
diplomatic
and human
contribution
made by
amateur
radio
operators
worldwide.
As early as
the 1960s
and 1970s,
rare moments
of openness
were
recorded. At
a time when
Israeli
amateur
radio
operators
were legally
prohibited
from
communicating
with Arab
countries,
one voice
nonetheless
broke
through:
that of a
Jordanian
radio
amateur
bearing the
unique call
sign JY1,
King
Hussein.
Hussein,
an avid
radio
enthusiast,
operated a
station from
the royal
palace and
at times
from London.
His contacts
with Israeli
radio
amateurs
were
exceptional.
He did not
limit
himself to
brief,
formal
exchanges,
known as
QSOs, but
held long,
friendly
conversations
marked by
genuine
human
curiosity.
This was an
unusual
phenomenon
at the time.
Years later,
following
the signing
of the peace
treaty, King
Hussein
invited
Israeli
amateur radio
operators for
an official
visit to
Amman and
presented
them with
gifts as
mementos.
Lockerbie 1988:
amateur radio
volunteers’ pivotal
communication in
disaster response
remembered in 2025
hirty-seven years
after the
devastating
Lockerbie bombing,
the extraordinary
efforts of amateur
radio enthusiasts
who provided a
crucial
communication
lifeline amid the
chaos continue to
resonate. As the
world reflects in
2025, their vital
role underscores the
enduring importance
of volunteerism and
resilient
communication
networks in times of
crisis.
On December 21,
1988, the small
Scottish town of
Lockerbie became the
site of an
international
tragedy when Pan Am
Flight 103 exploded,
scattering debris
and claiming 270
lives. The immediate
aftermath plunged
the area into
disarray,
overwhelming local
infrastructure and
conventional
communication
systems.
In the face of
unprecedented
destruction, a
unique group emerged
to bridge the
communication gap.
Amateur radio
operators, often
called “hams,”
swiftly mobilized,
transforming their
hobby into an
indispensable
emergency service,
connecting first
responders and
coordinating relief
efforts when other
means failed.
Following are
a few excerpts
from Claude’s
long (but good)
response. There
is a lot more at
the link and if
you are
interested in
learning more
about
AllStarLink,
it’s worth
reviewing.
From Claude:
What Is
AllStarLink?
AllStarLink
is a network
system that
connects amateur
radio repeaters,
remote base
stations, and
hotspots
worldwide using
Voice over
Internet
Protocol (VoIP).
Think of it as a
phone system for
radios—instead
of dialing phone
numbers, you
“dial” node
numbers to
connect
different radio
systems across
the internet.
Core
Architecture
The
Foundation:
Asterisk +
app_rpt
AllStarLink
is built on two
key components:
Asterisk PBX–
An open-source
phone system
(Private Branch
Exchange) that
handles audio
routing and call
management.
Asterisk is
essentially a
sophisticated
audio switching
system that was
designed for
telephone
systems.
app_rpt–
A custom
application
written
specifically for
Asterisk that
transforms it
into a repeater
controller. This
is the “secret
sauce” that
makes Asterisk
understand how
to work with
radios instead
of just phones.
Node
Architecture
What Is a
Node?
Anodeis
the basic
building block
of AllStarLink.
Each node
consists of:
Computer/Server–
Runs Linux
(typically
Debian) with
Asterisk and
app_rpt
software.
This can be:
Raspberry
Pi
(models
3, 4, 5,
or Zero
2 W)
Standard
PC
(x86_64/AMD64
architecture)
Virtual
machine
in the
cloud
Embedded
systems
Radio
Interface–
Connects the
computer to
radio
equipment
via:
USB
audio
adapters
(modified
or
commercial
like URI
devices)
PCI
radio
interface
cards
Sound
card
interfaces
Network
Connection–
Internet
connection
for linking
to other
nodes
Node
Number–
A unique
identifier
(like a
phone
number) that
other nodes
use to
connect

Obsolete Part 97
Rules to be Deleted
February 10, 2026
The Federal
Communications
Commission (FCC)
in October 2025
adopted a Report
and Order to
delete almost
400 obsolete
rules pertaining
to its wireless
services. Aspreviously
reported by ARRL,
among the
deletions were
four in Part 97
that govern the
Amateur Radio
Service.
ARRL reports
that the notice
of the Report
and Order has
now been
published in theFederal
Register.
Unless an
objection is
raised by
January 2 that
the Commission
finds to deserve
its
consideration,
the following
four Part 97
provisions will
be deleted as of
February 10,
2026:
§ 97.27.
This
provision is
duplicative
of a
statutory
provision
related to
the FCC’s
right to
modify
station
licenses.
§ 97.29.
This
provision
specified an
obsolete
procedure to
replace
paper
licenses.
ARRL
proposed
deleting
this section
in comments
filed
earlier this
year.
§ 97.315
(b)(2). This
obsolete
provision
grandfathered
HF
amplifiers
purchased
before April
28, 1978 by
an amateur
radio
operator for
use at that
operator's
station, and
grandfathered
those
manufactured
before April
28, 1978,
for which a
marketing
waiver was
issued.
4.§
97.521(b) and
Appendix 2. This
rule and
appendix relate
to obsolete VEC
regions.

An Introduction
to DC Motor
Technology
[Thinking Techie]
takes us back to
basics in a recent
video explaininghow
magnets, coils,
brushed DC motors,
and brushless DC
motors work. If
this is on your “to
learn” list, or you
just want a
refresher, you can
watch the video
below. It’ll be ten
minutes well-spent.
The video covers
the whole technology
stack behind the
humble DC motor in
its various
incarnations.
Starting with basic
magnetic effects, it
then proceeds
through 2-wire
brushed DC motors
and finally into
3-wire brushless DC
motors (BLDC
motors).
It’s worth
knowing that the
3-wires in a BLDC
motor are for three
power phases; they
are not, as in an RC
servo, positive,
negative, and signal
leads. But,
confusingly, the
BLDC motors in your
PC fansdohave
positive, negative,
and signal pins. But
that’s because, like
an RC servo, the
fans have
controllers built
into the case.

officers after he
was caught using a
sex toy in the back
of his car.
Mehboob Mohammed,
53, was initially
spotted by witnesses
in Glasgow’s

23, 2023.
Mohammed was
found half-naked
with his phone
propped up as he
committed a sex act
on himself.
He was reported
to the police, who
later found him in a
state of panic.
Mohammed went on
to drive at
excessive speeds, go
on the wrong side of
the road and went
through a red light
as officers pursued
him to East
Kilbride,
Lanarkshire.
Mohammed pled
guilty on Tuesday at
Glasgow
Sheriff Court to a
charge of public
indecency.
He also admitted
assaulting two
police officers,
dangerous driving
and failing to
appear at

REPORT: COOLING
IONOSPHERE COULD
DISRUPT, RESHAPE
RADIO COMMUNICATION
PAUL/ANCHOR: Our top
story takes us to
Japan, where
researchers studying
the ionosphere have
discovered that the
cooling of
temperatures up
there may cause
major shifts in our
ability to
communicate by
radio. Jason Daniels
VK2LAW brings us up
to date.
JASON: The continued
cooling of the
ionosphere 100 km
above sea level may
someday disrupt and
reshape shortwave
communications,
according to
scientists at Kyushu
University in Japan.
The drop in
ionospheric
temperatures is the
result of rising CO2
levels - the same
phenomenon
identified as the
source of global
warming down here on
Earth.
The researchers'
study, published in
Geophysical Research
Letters, found that
the cooling
ionosphere lowers
the air density and
speeds up wind
circulation - two
factors that have an
impact on satellite
orbits and space
debris. In addition,
the ability to
communicate by radio
also changes as a
result of
small-scale plasma
irregularities.
Shortwave radio,
radio broadcasting,
air traffic control
and maritime
communication could
all experience a
variety of major
changes, the
scientists said.
The study leader,
Huixin Liu of
Kyushu's Faculty of
Science, told the
Physics World
website: [quote]
"This may be good
news for ham radio
amateurs, as you
will likely receive
more signals from
faraway countries
more often. For
radio
communications,
however, especially
at HF and VHF
frequencies employed
for aviation, ships
and rescue
operations, it means
more noise and
frequent disruption
in communication and
hence safety."
[endquote]
She said that in the
long term, the
telecommunications
industry may need to
respond to these
changes by either
adjusting their
frequencies or
changing the design
of their equipment.

ISS EXPEDITION 73
CREW RETURNS TO
EARTH
PAUL/ANCHOR ISS
Expedition 73 has
ended with the
return to Earth of a
NASA astronaut and
two Roscosmos
cosmonauts. Graham
Kemp VK4BB has that
update.
GRAHAM: Roscosmos
cosmonauts Sergey
Ryzhikov and Alexey
Zubritsky returned
to Earth with US
astronaut Jonny Kim,
KJ5HKP, after 245
days in space aboard
the International
Space Station. Their
landing in Kazahstan
via Soyuz MS-27 on
the 9th of December,
ended Kim's tenure,
which included both
Expedition 72 and
73. It was the first
trip to the space
station for both Kim
and Zubritsky. Kim
received his amateur
radio operator's
license in July of
2024. While in
space, Kim
accomplished a
number of important
milestones,
including
participation in the
2025 ARRL Field Day
in the US with
fellow astronaut
Nichole Ayers
KJ5GWI. He was also
part of the space
station's first
transmission since
2018 of HamTV since
its repairs and

NEW NASA VIDEO GIVES
A WINDOW INTO ARISS
EXPERIENCE
PAUL/ANCHOR: A new
video from NASA is
giving viewers a
window into the
experience of
Amateur Radio on the
International Space
Station. Neil Rapp
WB9VPG tells us
more.
NEIL: Schools and
other educational
institutions who've
enjoyed student
contacts with
astronauts on board
the International
Space Station
already know the
value of this
respected program:
It places an
emphasis on science
and radio education
and gives a window
into how ham radio
works as a powerful
educational tool.
Now everyone can
experience
communication - at
least one-way
communication - with
a NASA astronaut in
a new video released
by NASA, the US
space agency. In a
little less than
four-minutes, the
NASA video features
astronaut Nichole
Ayers, KJ5GWI,
explaining to
viewers how school
contacts are made
with the help of ham
radio operators
around the world.
Addressing students
directly, she says
that the contacts
are meaningful but
necessarily brief
because the ISS is
moving around the
earth at a speed of
17,500 miles per
hour.
The video was
recorded -
appropriately-
during Expedition 73
which launched in

VERMONT MEDICAL
RESERVE CORPS
WELCOMES FORMER
RACES HAMS
PAUL/ANCHOR: Our
next story takes us
to Vermont where
former members of
the newly dismantled
RACES program are
learning new skills
as part of a new
team. Randy Sly W4XJ
has the details.
RANDY: Hams in
Vermont who had been
members of the
recently dismantled
Radio Amateur Civil
Emergency Service -
or RACES - have
begun joining the
team at the Medical
Reserve Corps of the
state's Department
of Health.
According to Kate
Hammond, KC1DUY,
manager of the
Medical Reserve
Corps'
communications
section, Vermont's
shift in deployment
of radio volunteers
is part of a
changeover going on
in many states. She
told Newsline in an
email that [quote]:
"...emergency
communications is
emerging as a
Medical Reserve
Corps mission in
more states, but the
creation of the
mission set in
Vermont is a work
that is specific to
us." [endquote] She
said that toward
that end, John Colt
NV1Y, the hospital
net coordinator for
the Medical Reserve
Corps, and Heather
Rigney KC1PMR, the
corps statewide
coordinator, are
overseeing the
creation of
documents for the
newly configured
team. Former RACES
materials are being
used to help guide
future practices of
Medical Reserve
Corps operators, who
will attend
orientation meetings
soon. The Vermont
Healthcare Net has
also become more
active. Kate said
that members will be
affiliated with one
of the eight local
Medical Reserve
Corps Units for any
drill or event --
and could be
deployed as well to
shelters when a
communications
outage occurs.
Although Josh Cohen,
KB1NIJ, a longtime
RACES member and an
experienced net
control operator,
told Newsline that
he is sorry to see
the RACES program
go, he is preparing
to join the Medical
Reserve Corps team.
Josh is among many
hams eager to
continue using their
skills.

KICKER: NIGHT BEFORE
CHRISTMAS, HAM RADIO
STYLE
PAUL/ANCHOR: We end
this newscast with a
Newsline holiday
tradition - a ham
log instead of a
yule log. Listen to
this much-loved
adaptation of the
Clement Clarke Moore
classic - proof that
there is still magic
in the season and
even moreso on the
amateur bands this
time of year. It was
written anonymously
- but is delivered
beautifully by our
own Jim Damron
N8TMW.
JIM: Twas the night
before Christmas and
all through the
shack
The rig was turned off and the mic cord lay slack
The antenna rotor had made its last turn, the tubes in the linear
had long ceased to burn.
I sat there relaxing and took off my specs, preparing to daydream of
Armchair DX-- When suddenly outside I heard such a sound, I dashed
out the door to see what was around.
The moon shone down brightly and lighted the night. For sure
propagation for the low bands was right.
I peered toward the roof where I heard all the racket and there was
some guy in a red, fur-trimmed jacket!
I stood there perplexed in a manner quite giddy: Just who WAS this
stranger? di di dah dah di dit?
He looked very much like an FCC guy who'd come to check up on some
bad TVI.
I shouted to him: "Old man...QR-Zed?"
"Hey you by the chimney all dressed up in red!"
I suddenly knew when I heard sleigh bells jingle
The guy on the rooftop was Jolly Kris Kringle
He had a big sack full of amateur gear which was a big load
for his prancing reindeer.
Transmitters, receivers, for cabinets and racks
Some meters and scopes and a lot of coax.
He said not a word 'cause he'd finished his work.
He picked up his sack and he turned with a jerk.
As he leaped to his sleigh, he shouted with glee
And I knew in a moment he'd be QRT.
I heard him transmit as he flew o'er the trees
"Merry Christmas to all, and to all seventy-three."

FRIDAY
EDITION: 50
MPH gusts today
should test the
antennas today, lots
of rain to boot....
Apocalypse:
Survivable
Low-Frequency
Communication System
In the global
game of nuclear
brinksmanship,
secrets are the coin
of the realm. This
was especially true
during the Cold War,
when each side
fielded armies of
spies to ferret out
what the other guy
was up to, what
their capabilities
were, and how they
planned to put them
into action should
the time come. Vast
amounts of blood and
treasure were
expended, and as
distasteful as the
whole thing may be,
at least it kept
armageddon at bay.
But secrets
sometimes work at
cross-purposes to
one’s goals,
especially when one
of those goals is
deterrence. The
whole idea behind
mutually assured
destruction, or MAD,
was the certain
knowledge that swift
retaliation would
follow any attempt
at a nuclear first
strike. That meant
each side had to
have confidence in
the deadliness of
the other’s
capabilities, not
only in terms of
their warheads and
their delivery
platforms, but also
in the systems that
controlled and
directed their use.
One tiny gap in the
systems used to
transmit launch
orders could spell
the difference
between atomic
annihilation and at
least the semblance
of peace.
During the height
of the Cold War, the
aptly named
Survivable
Low-Frequency
Communication System
was a key part of
the United States’
nuclear deterrence.
Along withGWEN,HFGCS,
andERCS,
SLFCS was part of
the alphabet soup of
radio systems
designed to make
sure the bombs got
dropped, one way or
another.
Nuking the
atmosphere, for
science. The
Starfish Prime
tests showed how
easily one could
deprive one’s
enemy of the use
of the
ionosphere.
Source: USAF
1352nd
Photographic
group, public
domain.
The hams have a
saying: “When all
else fails, there’s
amateur radio.” It’s
true, but it comes
with a huge caveat,
since hams rely on
the ionosphere to
bounce their
high-frequency (HF)
signals around the
world. Without that
layer of charged
particles, their
signals would just
shoot off into space
instead of traveling
around the world.
For the most
part, the ionosphere
is a reliable
partner in amateur
radio’s
long-distance
communications
networks, to the
point that Cold War
military planners
incorporated HF
links into their
nuclear
communications
systems. But since
at least the
Operation Argus and
Operation Hardtack
tests in 1958, the
United States had
known about the
effect of
high-altitude
nuclear explosions
on the ionosphere.
Further exploration
of these effects
through the Starfish
Prime tests in 1962
revealed just how
vulnerable the
ionosphere is to
direct attack, and
how easy it would be
to disrupt HF
communications
networks.
The vulnerability
of the ionosphere to
attack was very much
in the minds of U.S.
Air Force commanders
during the initial
design sessions that
would eventually
lead to SLFCS. They
envisioned a system
based on the
propagation
characteristics of
the EM spectrum at
lower frequencies,
in the low-frequency
(LF) and
very-low-frequency
(VLF) bands. While
wavelengths in the
HF part of the
spectrum are usually
measured in meters,
LF and VLF waves are
better measured in
kilometers, ranging
between 1 and 100
kilometers.
At these
wavelengths, radio
behaves very
differently than
they do further up
the dial. For LF
signals (30 to 300
kHz), the primary
mode of propagation
is via ground waves,
in which signals
induce currents in
the Earth’s surface.
These currents tend
to hug the surface,
bending with its
curvature and
propagating long
distances. For VLF
signals (3 to 30
kHz),
Earth-ionosphere
waveguide
propagation
dominates. Thanks to
their enormous
wavelengths, which
are comparable to
the typical altitude
of the lowest, or
D-layer, of the
ionosphere, the
waves “see” the
space between the
ground and the
ionosphere as a
waveguide, which
forms a low-loss
path that
efficiently guides
them around the
globe.
Critically for
the survivability
aspect of SLFCS,
both of these modes
are relatively
immune to the
ionospheric effects
of a nuclear blast.
That’s true even for
VLF, which would
seem to rely on an
undisturbed
ionosphere to form
the “roof” of the
necessary waveguide,
but the disruption
caused by even a
large blast is much
smaller than their
wavelengths,
rendering any
changes to the
ionosphere mostly
invisible to them.
Big Sticks
Despite the
favorable
propagation modes of
LF and VLF for a
communications
system designed to
survive a nuclear
exchange, those long
wavelengths pose
some challenges.
Chief among these is
the physical size of
the antennas
necessary for these
wavelengths. In
general, antenna
size is proportional
to wavelength, which
makes the antennas
for LF and VLF quite
large, at least on
the transmitting
side. For SLFCS, two
transmission sites
were used, one at
Silver Creek,
Nebraska, and
another in the
middle of the Mojave
Desert in Hawes,
California. Since
ground wave
propagation requires
a vertically
polarized signal,
each of these sites
had a guyed mast
radiator antenna
1,226 feet (373
meters) tall.
While the masts
and guy wire systems
were as reinforced
as possible, there’s
only so much that
can be done to make
a structure like
that resist a nuke.
Still, these
structures were
rated for a
“moderate” nuclear
blast within a
10-mile (16-km)
radius. That would
seem to belie the
“survivable” goal of
the system, since
even at the time
SLFCS came online in
the late 1960s,
Soviet ICBM accuracy
was well within that
limit. But the
paradox is resolved
by the fact that
SLFCS was intended
only as a backup
method of getting
launch orders
through to ICBM
launch facilities,
to be used to launch
a counterattack
after an initial
exchange that hit
other, more valuable
targets (such as the
missile silos
themselves), leaving
the ionosphere in
tatters.
The other
challenge of LF/VLF
communications is
the inherently low
data transfer rates
at these
frequencies. LF and
VLF signals only
have perhaps a
kilohertz to as few
as a few hertz of
bandwidth available,
meaning that they
can only encode data
at the rate of a few
tens of bits per
second. Such low
data rates preclude
everything but the
most basic
modulation, such as
frequency-shift
keying (FSK) or its
more spectrally
efficient cousin,
minimum-shift keying
(MSK). SLFCS
transmitters were
also capable of
sending plain old
continuous wave (CW)
modulation, allowing
operators to bang
out Morse messages
in a pinch. When all
else fails, indeed.
No matter which
modulation method
was used, the idea
behind SLFCS was to
trade communications
speed and
information density
for absolute
reliability under
the worst possible
conditions. To that
end, SLFCS was only
intended to transmit
Emergency Action
Messages (EAMs),
brief alphanumeric
strings that encoded
specific
instructions for
missile commanders
in their underground
launch facilities.
Buried Loops
While the
transmitting side of
the SLFCS equation
was paradoxically
vulnerable, the
receiving end of the
equation was
anything but. These
missile alert
facilities (MAFs),
sprinkled across the
upper Midwest,
consisted of ten
launch facilities
with a single
Minuteman III ICBM
in an underground
silo, along with one
underground launch
control center, or
LCC. Above ground,
the LCC sports a
veritable antenna
farm representing
almost the entire RF
spectrum, plus a few
buried surprises,
such as the very
cool HFGCS antenna
silos, which can
explosively deploy
any of six monopole
antennas up from
below ground to
receive EAMs after
the LCC has gotten
its inevitable
nuking.
The other
subterranean radio
surprise at LCCs is
the buried SLFCS
antenna. The buried
antenna takes
advantage of the
induced Earth
currents in ground
wave propagation,
and despite the
general tendency for
LF antennas to be
large is actually
quite compact. The
antennas were a
magnetic loop
design, with miles
of wire wrapped
around circular
semi-rigid forms
about 1.5 meters in
diameter. Each
antenna consisted of
two loops mounted
orthogonally, giving
the antenna a
globe-like
appearance. Each
loop of the antenna
was coated with
resin to waterproof
and stiffen the
somewhat floppy
structure a bit
before burying it in
a pit inside the LCC
perimeter fence. Few
examples of the
antenna exist above
ground today, since
most were abandoned
in place when SLFCS
was decommissioned
in the mid-1980s.
One SLFCS antenna
was recently
recovered, though,
and is currently on
display at theTitan
Missile Museumin
Arizona.
Sign of the
Times
Like many Cold
War projects, the
original scope of
SLFCS was never
fully realized. The
earliest plans
called for around 20
transmit/receive
stations, plus
airplanes equipped
with trailing wire
antennas over a mile
long, and more than
300 receive-only
sites across the
United States and in
allied countries.
But by the time
plans worked their
way through the
procurement process,
technology had
advanced enough that
military planners
were confident that
they had the right
mix of
communications modes
for the job. In the
end, only the
Nebraska and
California
transmit/receive
sites were put into
service, and even
the airborne
transmitters idea
was shelved thanks
to excessive drag
caused by that long
trailing wire.
Still, the SLFCS
towers and the
buried loop antennas
stayed in service
until the mid-1980s,
and the concept of
LF and VLF as a
robust backup for
strategic comms
lives on with the
Air Force’sMinimum
Essential Emergency
Communications
Network.

Hi Jon... Most
of the scary
stories about
solar events and
earth effects
have the tabloid
flavor, but this
one from The
Hill makes a bit
of sense. Not
that we can do a
damn thing about
it either way...
It is well
known that
pictographic
languages that
use Hanzi, like
Mandarin, are
difficult to
work with for
computer input
and output
devices. After
all, each
character is a
tiny picture
that represents
an entire word,
not just a
sound. But did
you ever wonder
howChina
used telegraphy?
We’ll admit, we
had not thought
about that until
we ran into
[Julesy]’s video
on the subject
that you can
watch below.
There are
about 50,000
symbols, so
having a bunch
of dots and
dashes wasn’t
really
practical. Even
if you designed
it, who could
learn it? Turns
out, like most
languages, you
only need about
10,000 words to
communicate. A
telegraph
company in
Denmark hired an
astronomer who
knew some
Chinese and
tasked him with
developing the
code. In a
straightforward
way, he decided
to encode each
word from a
dictionary of up
to 10,000 with a
unique
four-digit
number.
A French
expat took the
prototype code
list and
expanded it to
6,899 words,
producing “the
new telegraph
codebook.” The
numbers were
just randomly
assigned.
Imagine if you
wanted to say
“The dog is
hungry” by
writing “4949
1022 3348 9429.”
Not to mention,
as [Julesy]
points out, the
numbers were
long driving up
the cost of
telegrams.
It took a
Chinese delegate
of what would
eventually
become the
International
Telecommunication
Union (ITU) to
come up with a
method by which
four-digit codes
would count as a
single Chinese
character. So,
for example,
1367 0604 6643
0932 were four
Chinese
characters
meaning:
“Problem at
home. Return
immediately.”
Languages
like Mandarin
make typewriters
tough, butnot
impossible.
IBM’s had 5,400
characters andalso
used a
four-digit code.
Sadly, though,
they were not
the same codes,
so knowing
Chinese Morse
wouldn’t help
you get a job as
a typist.
WEDNESDAY
EDITION: I
bought an Icom 7300
many years ago when
it was on sale for a
decent price and
have used it on 75
meters ssb and
digital modes with a
little 811 amp. It
has been a very
reliable radio with
the shortcomings of
not being able to
plug a monitor in to
it. The new Icom
7300 MKII has the
hdmi outlet for a
screen which solves
that issue for me,
of course I will not
upgrade for what it
would cost me.
I did buy a Yaesu
710 which provided
the hdmi port to
allow a monitor to
be connected
directly. Both of
these radios are
just backup rigs for
my main station, an
Icom 7600 and Acom
amplifier. I prefer
the 7300 for
operation because I
find it easier to
maneuver the menu
structure than that
of the 710, I
never cared for the
Yaesu menu system. I
guess mypoint is if
someone asked me if
they should buy a
new 7300MKII or a
710, I would sit
them down at the
club and let them
try each radio. I
think if I only had
the money to buy
only one radio, the
Yaesu 710 is a
better bargain than
the new Icom
7300MKII...but the
Icom 7300MKII would
be my choice.

American Public
Media Settles With
FCC Over False EAS
Tones
A program that
aired on more than
500 U.S.
noncommercial radio
stations in 2023
contained Emergency
Alert System tones
in the absence of a
real emergency,
according to the
FCC.
American Public
Media Group, the
distributor of the
program, agreed to a
consent decree with
the commission’s
Enforcement Bureau
on Dec. 10.
APMG, the parent
of American Public
Media, a creator and
distributor of
programming to
public radio
stations across the
U.S., will be making
a voluntary
contribution of
$86,400 to the U.S.
Treasury Department
as a result of the
transmission of EAS
tones during a “BBC
Witness History”
program on tornado
chasing.
The commission’s
rules forbid the use
of EAS tones on the
air outside actual
emergencies or
coordinated tests.
“Unauthorized use
of the EAS tones
thus presents a
substantial threat
to public safety,”
the FCC said in its
notice on the
consent decree.
Just because you
are paranoid doesn’t
mean people aren’t
out to get you. Do
you think your
soldering iron is
after you? Well,
[nanofix] asks (and
answers):Is
My Soldering Iron
Dangerous?
He has a look at
his cheap FNIRSI
soldering station
and measures a
“phantom voltage” of
nearly 50 volts AC
across the tip of
his iron and earth
ground. He explains
that this phantom
voltage is a very
weak power source
able to provide only
negligible measures
of current; indeed,
he measures the
short circuit
current as 0.041
milliamps, or 41
microamps, which is
negligible and
certainly not
damaging to people
or components.
He pops open his
soldering iron power
supply (being
careful to discharge
the high voltage
capacitor) and has a
look at the switched
mode power supply,
with a close look at
the optocoupler andY-class
capacitor, which
bridge the high
voltage and low
voltage sides of the
circuit board. The
Y-class capacitor is
a special type of
safety capacitor
designed to fail
open rather than
fail short. The
Y-class capacitor is
there to remove
high-frequency
noise. Indeed, it is
this capacitor that
is the cause of the
phantom voltage on
the iron tip.
He continues by
explaining that you
can install a 1M
resistor across some
pads on the
high-voltage side of
the board if you
really want to get
rid of the phantom
voltage on your
iron, but he
emphasizes that this
isn’t really
necessary. And to
finish, he
demonstrates that a
sensitive MOSFET
isn’t damaged at all
when it’s connected
to the phantom
voltage.
It is perhaps
worth noting that
there is a
difference between
phantom voltage (as
seen above with
negligible power)
andphantom
power. Phantom
power can deliver
non-negligible
amounts of power and
isoften
used in microphones.
DXLook
Introduces Real-Time
D-RAP Visualization
for HF Absorption
Events
DXLookhas
released a new D-RAP
(D-Region Absorption
Prediction) view
that helps amateur
radio operators
understand and
visualize HF
absorption caused by
solar X-ray flares
in real time.
D-region
absorption is a
major cause of
sudden daytime HF
blackouts,
particularly on
lower-frequency
bands. DXLook’s new
D-RAP view presents
existing D-region
absorption data in a
band-aware,
geographic format,
allowing operators
to visually assess
where and on which
HF bands absorption
may be occurring at
a given moment.
The D-RAP view is
primarily driven by
official data from
the NOAA Space
Weather Prediction
Center, using the
global “frequency
for 1 dB absorption”
product based on
GOES satellite X-ray
measurements. This
dataset identifies,
for each region of
the Earth, the
highest HF frequency
expected to
experience
significant D-layer
absorption at the
current time.
When NOAA data is
unavailable or
becomes outdated,
DXLook automatically
switches to a
physics-based
fallback model
derived from
real-time solar
position
calculations. The
system clearly
indicates when
calculated data is
being used instead
of measured NOAA
data, ensuring
transparency for
users.
Absorption
regions are
displayed as smooth,
color-coded zones
aligned with amateur
HF bands, allowing
operators to quickly
assess which
frequencies may be
degraded. The D-RAP
view integrates with
DXLook’s existing
MUF, spot, and
propagation tools,
helping users
understand the full
operating window
between D-layer
absorption at lower
frequencies and
ionospheric
refraction limits at
higher ones.
The new D-RAP
view is especially
useful for contest
operators, DXers,
and emergency
communications
groups assessing HF
reliability during
solar events, as
well as for
operators trying to
understand sudden
short-wave fadeouts
during daylight
hours.
The D-RAP view is
now live and
available to all
users athttps://dxlook.com.
About DXLook
DXLook is a
real-time HF and VHF

TUESDAY
EDITION: 23
degrees to start the
day...about time to
start
selling these again...
This is a
topic that
has caused a
lot of
confusion.
Since 2022,
self-spotting
has been
permitted in
all ARRL
contests,
even when
operating in
the
“Unassisted”
category,
because
self-spotting
is not
considered
“spotting
assistance.”
This is
clearly
stated in
item 6 of
the HF
Contesting
Guidelines
at the
following
link:
https://www.arrl.org/hf-contesting-guidelines
.
In addition,
the former
ARRL
Director of
Operations,
W5OV (may he
rest in
peace),
confirmed
this in the
ARRL
Contesting
Group in
December
2022. Here
is the link
to that
discussion:
https://groups.arrl.org/.../self_spotting_and_arrl/95716202
.
I believe
the current
ARRL contest
committee
should be
clearer in
its rules.
Although
this is
clearly
explained in
the
Contesting
Guidelines,
the same
information
should also
be
explicitly
included in
the rules of
each
individual
contest.
Even as we
approach
2026, there
is still a
great deal
of confusion
regarding
self-spotting
in the
No-Assisted
category.
I am sharing
this solely
for the
benefit of
all
contesters.

NASA May Have
Lost the MAVEN Mars
Orbiter
When the orbit of
NASA’s Mars
Atmosphere and
Volatile EvolutioN
(MAVEN) spacecraft
took it behind the
Red Planet on
December 6th, ground
controllers expected
a temporary loss of
signal (LoS).
Unfortunately, the
Deep Space Networkhasn’t
heard from the
science orbiter
since. Engineers
are currently trying
to troubleshoot this
issue, but without a
sign of life from
the stricken
spacecraft, there
are precious few
options.
As noted by
[Stephen Clark] over
at ArsTechnicathisis
a pretty big deal.
Even though MAVEN
was launched in
November of 2013,
it’s a spring
chicken compared to
the other Mars
orbiters. The two
other US orbiters:
Mars Reconnaissance
Orbiter (MRO) and
Mars Odyssey, are
significantly older
by around a decade.
Of the two ESA
orbiters, Mars
Express and ExoMars,
the latter is fairly
new (2016) and could
at least be a
partial backup for
MAVEN’s
communication relay
functionality with
the ground-based
units, in particular
the two active
rovers. ExoMars has
a less ideal orbit
for large data
transfers, which
would hamper
scientific research.
With neither the
Chinese nor UAE
orbiters capable of
serving as a relay,
this puts the burden
on a potential
replacement orbiter,
such as the
suggestedMars
Telecommunications
Orbiter, which
was cancelled in
2005. Even if
contact with MAVEN
is restored, it
would only have fuel
for a few more
years. This makes a
replacement
essential if we wish
to keep doing
ground-based science
missions on Mars, as
well as any
potential manned
missions.
Testing Whether
Fast Charging Kills
Smartphone
Batteries, and Other
Myths
With batteries
being such an
integral part of
smartphones, it’s
little wonder that
extending the period
between charging and
battery replacement
has led to many
theories and
outright myths about
what may affect the
lifespan of these
lithium-ion
batteries. To bust
some of them, [HTX
Studio] over on
YouTube has spent
the past two years
torturing both
themselves and a
myriad ofboth
iOS and Android
phonesto
tease out some
real-life data.
After a few false
starts with smaller
experiments, they
settled on an
experimental setup
involving 40 phones
to investigate two
claims: first,
whether fast
charging is worse
than slow charging,
and second, whether
limiting charging to
80% of a battery’s
capacity will
increase its
lifespan. This
latter group
effectively uses
only 50% of the
capacity, by
discharging down to
30% before
recharging. A single
control phone was
left alone without
forced
charge-discharge
cycles.
After 500 charge
cycles and 167 days,
these three groups
(fast, slow, 50%)
were examined for
remaining battery
capacity. As one can
see in the above
graphic for the
Android group and
the similar one for
iOS in the video,
the results are
basically what you
expect. Li-ion
batteries age over
time (‘calendar
aging’), with
temperature and
state-of-charge
(SoC) affecting the
speed of this aging
process, as can be
seen in the SoC
graph from an
earlier article thatwe
featured on built-in
batteries.
It seems that
keeping the battery
as cool as possible
and the SoC as low
as possible, along
with the number of
charge-discharge
cycles, will extend
its lifespan, but
Li-ion batteries are
doomed to a very
finite lifespan on
account of their
basic chemistry.
This makes these
smartphone charging
myths both true, but
less relevant than
one might assume, as
over the lifespan of
something like a
smartphone, it won’t
make a massive
difference.

STORY
FCC Allocates
60-Meter World-Wide
Amateur Band
Approved at WRC-15;
Continues Amateur
Use of Four
Additional 60-Meter
Channels, and
Updates 420 MHz
Coordination
Information
The
Federal
Communications
Commission (FCC)
on December 9,
2025, released a
long-awaited Report
and Order adopting
a new amateur
radio spectrum
allocation in
the 60-meter
band that was
approved for
world-wide use
on a secondary
basis in the
WRC-15 (World
Radiocommunication
Conference
2015) Final
Acts. The
Commission also
agreed with a
petition from ARRL The
National
Association for
Amateur Radio®
to continue to
allow amateur
operations on
four existing
60-meter
channels outside
the
international
allocation with
a full 100
watts. The new
rules will go
into effect 30
days after
publication in
the Federal
Register, when
amateurs may
then begin using
the allocation.
Specifically,
the Commission
allocated 5351.5
- 5366.5 kHz (60
meters) to the
amateur
service on a
secondary basis
with a permitted
power of 9.15
watts ERP. The
Commission also
authorized
amateurs to
continue using
four existing
channels outside
of the 5351.5 -
5366.5 kHz band
centered on
5332, 5348,
5373, and 5405
kHz on a
secondary basis
with a permitted
power of 100
watts ERP. There
are no antenna
restrictions but
antenna gain
must be used to
calculate ERP.
The
60-meter
allocation is
available to
amateurs holding
a General Class
or above
license. The
maximum
permissible
signal bandwidth
is 2.8 kHz.
Amateurs are
cautioned that
this allocation
is strictly on a
secondary basis,
and amateurs
must avoid
interfering with
non-amateur
stations using
this spectrum.
This obligation
includes the
responsibility
to monitor for
such stations
using
appropriate
receiver
bandwidths. The
FCC emphasized
that “allowing
amateur
operations in
this band while
fully protecting
incumbent
primary Federal
operations is
our priority,
and even
intermittent
interference in
this band could
jeopardize
important
Federal
operations.”
The
Commission left
open ARRL’s
2017 Petition
for Rulemaking to
implement this
WRC allocation
(RM-11785),
stating that “we
expect the
Commission may
address any
necessary power
adjustments for
the new 15
kilohertz
international
allocation in
that
proceeding.” ARRL
will be
observing
operations in
the new band to
evaluate the
effect of the
9.15-watt limit
and already has
been monitoring
the regulations
and experiences
of amateurs in
other countries.
Finally, in the
same Report and
Order, the FCC
updated 420 -
450 MHz
coordination and
contact
information for
geographic areas
where the peak
envelope power
(PEP) of amateur
stations
operating is
generally
limited to 50
watts. There was
no substantive
change to the
areas covered by
the power
limitation.

Failed 3D
Printed Part Brings
Down Small Plane
Back in March, a
small aircraft in
the UK lost engine
power while coming
in for a landing and
crashed. The
aircraft was a total
loss, but
thankfully, the
pilot suffered only
minor injuries.
According to therecently
released report by
the Air Accidents
Investigation Branch,
we now know a failed
3D printed part is
to blame.
The part in
question is a
plastic air
induction elbow — a
curved duct that
forms part of the
engine’s air intake
system. The
collapsed part you
see in the image
above had an air
filter attached to
its front (towards
the left in the
image), which had
detached and fallen
off. Heat from the
engine caused the
part to soften and
collapse, which in
turn greatly reduced
intake airflow, and
therefore available
power
While the cause
of the incident is
evident enough,
there are still some
unknowns regarding
the part itself. The
fact that it was 3D
printed isn’t an
issue. Additive
manufacturing is
used effectively in
the aviation
industry all the
time, and it seems
the owner of the
aircraft purchased
the part at an
airshow in the USA
with no reason to
believe anything was
awry. So what
happened?
The part in
question is normally
made from laminated
fiberglass and
epoxy, with a glass
transition of 84° C.
Glass transition is
the temperature at
which a material
begins to soften,
and is usually far
below the material’s
actual melting
point.
When a part is
heated at or beyond
its glass
transition, it
doesn’tmeltbut
is no longer “solid”
in the normal sense,
and may not even be
able to support its
own weight. It’s the
reason some folkspack
parts in powdered
salt to support thembefore
annealing.
The printed part
the owner purchased
and installed was
understood to be
made from CF-ABS, or
ABS with carbon
fiber. ABS has a
glass transition of
around 100° C, which
should have been
plenty for this
application.
However, the
investigation tested
two samples taken
from the failed part
and measured the
glass temperature at
52.8°C and 54.0°C,
respectively. That’s
a far cry from what
was expected, and
led to part failure
from the heat of the
engine.
The actual
composition of the
part in question has
not been confirmed,
but it sure seems
likely that whatever
it was made from, it
wasn’t ABS. The
Light Aircraft
Association (LAA)
plans to circulate
an alert to
inspectors regarding
3D printed parts,
and the possibility
they aren’t made
from what they claim
to be.

Japan’s
Forgotten Analog
HDTV Standard Was
Well Ahead Of Its
Time
When we talk
about HDTV, we’re
typically talking
about any one of a
number of standards
from when television
made the paradigm
switch from analog
to digital
transmission. At the
dawn of the new
millenium,
high-definition TV
was a step-change
for the medium,
perhaps the biggest
leap forward since
color transmissions
began in the middle
of the 20th century.
However, a
higher-resolution
television format
did indeed exist
well before the TV
world went digital.
Over in Japan,
television engineers
had developed an
analog HD format
that promised
quality far beyond
regular old NTSC and
PAL transmissions.
All this, decades
before flat screens
and digital TV were
ever seen in
consumer households!
Resolution
Japan’s efforts
to develop a better
standard of analog
television were
pursued by the
Science and
Technical Research
Laboratories of NHK,
the national public
broadcaster.
Starting in the
1970s, research and
development focused
on how to deliver a
higher-quality
television signal,
as well as how to
best capture, store,
and display it.

FCC GRANTS HAMS
NON-CHANNELIZED USE
ON 60M
PAUL/ANCHOR: Hams in
the US are getting
expanded,
non-channelized use
of parts of the 60m
band under a recent
decision by the
Federal
Communications
Commission. The new
access applies to
General and Extra
Class
license-holders who,
until now, were
granted use on a
secondary basis of
four discrete
channels: 5332,
5348, 5373, and 5405
kHz. In a decision
released on December
9th, the FCC
reaffirmed the
continued amateur
use of these
existing four
channels at 100
watts of power,
saying there have
been no interference
issues with federal
operations.
The FCC said, that
in-line with the
international WRC15
allocation,
contiguous use
between 5351.5 and
5366.5 kHz with a
limited emission
bandwidth of 2.8 kHz
and power of no more
than 15 watts EIRP
is being granted.

BELGIAN EVENT MARKS
BATTLE OF THE BULGE
ANNIVERSARY
PAUL/ANCHOR: History
has marked the
Battle of the Bulge
as the turning point
in World War II.
Amateur radio is
marking it too - as
a special event
noting its 81st
anniversary this
year. Jeremy Boot
G4NJH has those
details.
JEREMY: The Battle
of the Bulge was
Adolf Hitler's final
major offensive on
the Western Front.
His attempt to repel
the Allies from
German-held
territory did not
succeed. On the 22nd
December 1944, the
Germans delivered an
ultimatum to
surrender to the
Allies in Bastogne,
Belgium -- and the
single-word response
from US Gen. Anthony
McAuliffe became one
for the history
books.
His reply was
"NUTS!"
That word forms the
suffix of the
special event
station callsign
being used by
members of the
Brussels Radio Club
BXE. Station
OR81NUTS will be on
the air from the
Bastogne Barracks
using CW and SSB on

TRAVIS: When Alan
Waller, K3TKJ,
created the QSL.net
and QTH.net websites
in 1996, he
succeeded in
expanding the
universe of online
information for his
fellow amateurs. Al,
who got his license
in 1962, made a name
for himself over the

and as a big fan of
DXing on 6 metres.
Diagnosed with
Non-Hodgkin
Lymphoma, he became
a Silent Key on the
30th of November.
In 2002, Al's
contributions to
amateur radio earned
him the Dayton
Hamvention Technical
Excellence Award. In
2008, he retired
from running his two
websites, entrusting
them to Scott KA9FOX
so the resources
could remain
available.
A statement on the

its Jubilee year
activities conclude
on the 31st of
December, the radio
station will once
again engage in one
of its most popular
traditions, its
Christmas Eve
message, a longwave
transmission in CW.
Graham Kemp VK4BB
tells us more.
GRAHAM: One hundred
Christmas Eves will
have come and gone
when the callsign
SAQ transmits the
Christmas Eve
message from the
Grimeton Radio
Station in Sweden on
the morning of
December 24th. The
operator will again
be using the
much-loved
transmitter, which
utilises an
alternating-current
generator developed
by the pioneering
Swedish engineer
Ernst Alexanderson.
The Christmas Eve
morning transmission
will be sent on 17.2
kHz about a
half-hour after the
transmitter has been
started up. It is a
festive occasion on
the radio station
site itself but for
those who cannot be
there personally,
the message can be
heard on the air, of
course, and seen on
the YouTube channel
of the Alexander SAQ
Grimeton Friendship

AN "ANTENNA RACING"
EVENT THAT'S ALL IN
GOOD SPORT
PAUL/ANCHOR: We end
this week with a
sports story.
Recently, as elite
drivers of
motorsport were
causing the world's
hearts to race
alongside them on
the Formula 1 track
in Abu Dhabi, a
quiet field in New
Zealand erupted with
the nail-biting
action of the 2025
Antenna Racing World
Championship. Of
course, only this
small part of the
immediate world was
participating. Just
ask John Williams
VK4JJW, who has this
report.
JOHN: The quartet of
contenders were
locked in what one
on-site moderator
called [quote] "a
battle of pure
technical
fury."[endquote]
Their telescoping
masts, their coax
and their antenna
analysers were ready
for action.
Introducing this
world-class portable
antenna-building
competition was
Amateur Radio
Newsline's own Jim
Meachen ZL2BHF, a
commentator on the
sidelines along with
event organiser,
Nick ZL2NEB.
There were more than
a few tense moments
in this Kaikoura
park -- and there
was no room for
cheating: Speed of
deployment and low
SWR were everything.
This event showcased
what Jim called
[quote] "high-octane
engineering
athletics."
[endquote] It was
all up to Malcolm,
ZL4MWB, Nick,
ZL2NEB, Graeme,
ZL1BDS and Stewart,
ZL2STR, each taking
turns, one by one,
to show that their
antennas could
resonate with the
best of them.
Nick, who had
jokingly suggested
creating the
competition, was
pleased to see
POTA/SOTA activators
embrace this chance
to rev their
engines. Like
Formula 1 cars,
competitors had to
stay on track.
So who won the
coveted 40m dipole
that had been
donated by Greg
ZL1GUD from the
HamShack? Tune in to
find out, sports
fans: We're

How Joe
Walsh Used a
Signature
Guitar to
Pay Homage
to the Man
Who “Saved
Him” During
a Lonely
Summer in
New York
City
Guitarists
have been
personalizing
their
instruments
since time
immemorial,
whether with an
embossed leather
guitar strap,
pearly fretboard
inlay that
spells out the
performer’s
name, or a
guitar with
plenty of body
and electronic
modifications
that make the ax
completely
distinct. But
far fewer
musicians can
boast a
personalized
guitar that
spells out their
name in Morse
code. Eagles
guitarist and
prolific solo
artist Joe Walsh
is one of them,
though.
In addition to
being one of the
most well-known
guitarists of
20th-century rock
‘n’ roll, Walsh is
also a lifelong ham
radio operator. Even
today, his amateur
license with the
Federal
Communications
Commission is
active through 2031
under the call sign
WB6ACU. The “Rocky
Mountain Way”
singer’s signature
Alliance series with
Duesenberg guitars
pays tribute to this
decades-long passion
by spelling out
Walsh’s name in
Morse code along the
fretboard.
And although it’s
Walsh’s name that
appears on his
signature guitar,
it’s also
inadvertently paying
homage to a
different man named
Jim.
The Man Who Helped
“Save” Joe Walsh One
Lonely Summer
WhenJoe
Walshwas
around 11 years old,
he experienced
something no kid
ever wants to
experience: his
family moved him
from his hometown of
Columbus, Ohio, to
the bustling
metropolis of New
York City, hundreds
of miles away from
his friends and all
that was familiar to
him, at the start of
summer break. While
this might seem like
the logical move
from an adult
perspective, it’s
practically
torturous for a kid
who, without school
being in session,
has far fewer
opportunities to
make friends.
Unsurprisingly,
Walsh spent most of
the summer alone.
But all that
alone time gave him
plenty of time to
observe his
apartment building,
which he noticed had
a massive antenna on
the roof. “Every
time I looked up at
it, it was pointing
a different
direction,” Walsh
said in a2014
interview on theThis
Week in Techpodcast.
“So, after a while,
I followed the wires
down to a window,
traced that to a
door, and knocked on
the door. It was
K2IEY. His name was
Jim, and he was a
ham. He invited me
in and sat me down
in his little shack,
and he had a KWM1
transceiver, and he
talked to the world
on it. I was amazed.
That was my first
real friend in New
York.”
“Jim kind of
saved me that
summer,” Walsh
continued, “and
became a lifelong
friend.” Thanks to
Jim, ham radio also
became a lifelong
passion Walsh would
pursue between, you
know, being an
internationally
renowned rock star.
In December 2025,Julien’s
Auctionsannounced
they were hosting
the first-ever
auction from Joe
Walsh, which
includes the
prototype of hissignature
guitar, complete
with Morse code
inlays. And while
Walsh might be
parting with his
first ax that
harkens back to his
ham radio operator
roots, he’s
certainly not
signing off the air.
In fact, Walsh has
made a point to
continue the
tradition that Jim
taught him all those
years ago in New
York City.
“Every once in a
while, somebody
comes and knocks at
my door and says,
‘What’s that thing
on your roof?’”
Walsh said in aJulien’s
Auctions items
preview. “I say,
‘Come on in. Been
waiting for you.’
‘Cause that’s what
we do.”
FCC Allocates
60-Meter World-Wide
Amateur Band
Approved at WRC-15;
Continues Amateur
Use of Four
Additional 60-Meter
Channels, and
Updates 420 MHz
Coordination
Information
The
Federal
Communications
Commission (FCC)
on December 9,
2025, released a
long-awaited Report
and Order adopting
a new amateur
radio spectrum
allocation in
the 60-meter
band that was
approved for
world-wide use
on a secondary
basis in the
WRC-15 (World
Radiocommunication
Conference
2015) Final
Acts. The
Commission also
agreed with a
petition from ARRL The
National
Association for
Amateur Radio®
to continue to
allow amateur
operations on
four existing
60-meter
channels outside
the
international
allocation with
a full 100
watts. The new
rules will go
into effect 30
days after
publication in
the Federal
Register, when
amateurs may
then begin using
the allocation.
Specifically,
the Commission
allocated 5351.5
- 5366.5 kHz (60
meters) to the
amateur
service on a
secondary basis
with a permitted
power of 9.15
watts ERP. The
Commission also
authorized
amateurs to
continue using
four existing
channels outside
of the 5351.5 -
5366.5 kHz band
centered on
5332, 5348,
5373, and 5405
kHz on a
secondary basis
with a permitted
power of 100
watts ERP. There
are no antenna
restrictions but
antenna gain
must be used to
calculate ERP.
The
60-meter
allocation is
available to
amateurs holding
a General Class
or above
license. The
maximum
permissible
signal bandwidth
is 2.8 kHz.
Amateurs are
cautioned that
this allocation
is strictly on a
secondary basis,
and amateurs
must avoid
interfering with
non-amateur
stations using
this spectrum.
This obligation
includes the
responsibility
to monitor for
such stations
using
appropriate
receiver
bandwidths. The
FCC emphasized
that “allowing
amateur
operations in
this band while
fully protecting
incumbent
primary Federal
operations is
our priority,
and even
intermittent
interference in
this band could
jeopardize
important
Federal
operations.”
The
Commission left
open ARRL’s
2017 Petition
for Rulemaking to
implement this
WRC allocation
(RM-11785),
stating that “we
expect the
Commission may
address any
necessary power
adjustments for
the new 15
kilohertz
international
allocation in
that
proceeding.” ARRL
will be
observing
operations in
the new band to
evaluate the
effect of the
9.15-watt limit
and already has
been monitoring
the regulations
and experiences
of amateurs in
other countries.
Finally, in the
same Report and
Order, the FCC
updated 420 -
450 MHz
coordination and
contact
information for
geographic areas
where the peak
envelope power
(PEP) of amateur
stations
operating is
generally
limited to 50
watts. There was
no substantive
change to the
areas covered by
the power
limitation.
Lithium-Ion
Batteries: WHY They
Demand Respect
This summer, we
saw the WHY (What
Hackers Yearn) event
happen in
Netherlands, of
course, with a badge
to match. Many
badges these days
embrace the QWERTY
computer aesthetic,
which I’m personally
genuinely happy
about. This one used
18650 batteries for
power, in a dual
parallel cell
configuration… Oh
snap, that’s my
favourite LiIon cell
in my favourite
configuration, too!
Surely, nothing bad
could happen?
Whoops.That
one almost caught me
by surprise, I have
to shamefully admit.
I just genuinely
love 18650 cells, in
all glory they bring
to hardware hacking,
and my excitement
must’ve blindsided
me. They’re the
closest possible
entity to a “LiIon
battery module”,
surprisingly easy to
find in most corners
of this planet,
cheap to acquire in
large quantities,
easy to interface to
your projects, and
packing a huge
amount of power.
It’s a perfect cell
for many
applications I and
many other hackers
hold dear.
Sadly, the 18650
cells were a bad
choice for the WHY
badge, for multiple
reasons at once. If
you’re considering
building a
18650-based project,
or even a product,
let me show you what
exactly made these
cells a bad fit, and
how you might be
able to work around
those limitations on
your own journey.
There’s plenty of
technical factors,
but I will tell you
about the social
factors, because
these create the
real dealbreaker
here.
The main social
factor can be boiled
down to this – a
18650-powered WHY
badge can start a
fire through being
touched by a 5 cent
coin, a keychain, or
a metal zipper of
someone’s jacket.
This is not a
dealbreaker for an
individual hacker
who’s conscious of
the risk, though
it’s certainly an
unwise choice. For
three thousand
participants? You
have no chance.
A 18650 cell is
like a bigger sister
to an AA battery –
power at your
fingertips, just,
you’re playing with
heaps more power.
You can take a 18650
cell and have it
power a small yet
nimble robot on
wheels, or an ultra
powerful flashlight,
or a handheld radio
packing quite a
transmit power
punch. You can
release its power on
accident, too, and
that gets nasty
quick.
Short-circuiting
a 18650 cell is a
surprisingly
straightforward way
to melt metal, and
by extent, start a
small fire. It’s
also not that hard
to short-circuit a
18650 cell,
especially and
specifically
unprotected ones.
This is a big part
of why consumer
oriented gadgets use
AAs instead of
18650s – it’s
perhaps less
powerful, sure, but
it’s also a
significantly less
dangerous cell.
The
Instructions, They
Do Nothing!
WHY sold a little
over 3700 tickets. I
would not expect
100% attendance, but
I’m comfortable
saying it must’ve
been around three
thousand people.
Sadly, “three
thousand people” is
far beyond the point
when you can hope to
give people handling
instructions for
something as easy to
mishandle as LiIon
cells, even for a
nominally hacker
audience.
Of course, youcantry
and give people
instructions. You
can talk to each
badge recipient
individually,
release booklets
demonstrating what
to do and not to do
with a 18650 cell,
add silkscreen
instructions for a
just-in-place
reminder, or maybe
have them sign a
release form, though
it’s unlikely that
kind of trick would
be legal in the EU.
Sadly, WHY
organizers never
came close to doing
any of these things.
It also wouldn’t
really matter if
they did. These
instructions will
always, inevitably
be outright ignored
by a sizeable
percentage of users.
Handling
unprotected
batteries requires
cautiousness and
some helper
equipment. You can’t
hope to transplant
the cautiousness, at
most you can try and
issue the equipment.
Which equipment? A
small storage cases
for the cells (must
have when
transporting them!),
as well as a case
for the badge, at
the very least; to
my knowledge, the
WHY didn’t issue
either of these
stock. An ESD bag
doesn’t qualify if
it doesn’t
permanently cover
the badge’s back,
because any
temporary protection
is nullified by a
budding hacker
getting tired of
carrying two 18650
cells on their neck,
and throwing the
badge into the tent
without looking.
Where does it land?
Hopefully not onto
something metal.
You can build a
badge or any sort of
other device using
unprotected 18650s,
which expects the
end user to handle
them, like the WHY
badge does, and it
will be more or less
safe as long as the
end user is
yourself, with 18650
handling experience
that I’m sure is to
match. Giving it to
a friend, caseless?
You can talk to your
friend and explain
18650 handling
basics to them,
sure, but you’re
still running some
degree of risk. My
hunch is, your
friend could very
well refuse such a
gift outright.
Giving it to a
hundred people?
You’re essentially
playing with fire at
someone else’s
house.
Just Why Did
That Happen?
Hackaday has
traditionally used
AA cells for our
badges, which has
definitely help us
mostly avoid any
Lithium-related
issues. Most other
conferences have
been using pouch
cells, which
traditionally come
with short-circuit
protection and don’t
threaten to ignite
stuff from contact
with a piece of
metal. 18650 cells
are not even cheaper
at scale – they’re
nice, sure, I wrote
as much, but those
nice things are
quickly negated by
the whole
“firestarter” thing.
On the other
hand, 18650 cells do
work for a hacker or
a small team of
hackers skilled
enough to stay
cautious, and it
also works well at
scale when the cell
is permanently
encased within the
shell, like in most
powerbanks and
laptops. It fails as
soon as you expect
people to plug
batteries in and
out, or carry them
separately.
Respecting
Lithium-Ion
batteries means
being aware of their
shortcomings, and
for 18650 cells,
that means you
should avoid having
people manually
handle them at
scale.
Here’s the kicker
about the WHY badge
situation. I was
confused by the WHY
badge switching to
18650 cells this
year, away from
overcurrent-protected
pouch cells, which
were used by
previous iterations
of WHY (MCH,SHA)
without an issue in
sight. So, I’ve
asked around, and
what I got from
multiple sources is
– the 18650 usage
decision was pushed
top-down, with
little regard for
physical safety.
Sadly, this makes
sense – it’s how we
saw it implemented,
too
