WEEKEND EDITION: Sunny and windy good day for getting outside...away from the radio Why Does the FCC Care About Computers?Unless you are over a certain age, you probably take it for granted that electronic gadgets you buy have some FCC marking on them. But it wasn’t always true. [Ernie] submits that the FCC’s regulation of the computer industry was indirectly the result of the success of CB radio in that same time period. Today, there is a high chance you don’t watch TV directly over the airwaves or even consume audio from a traditional radio station. Even if you do, the signal is increasingly likely to be digital. But only analog radio and TV were highly susceptible to interference. When a professional radio station or the power company interfered with you watching I Love Lucy, you could count on them to resolve it. Even ham radio operators, a small segment of the population, would, in general, graciously help you if their transmissions interfered with your equipment. Never mind that, in many cases, it was the cheap TV or some other problem on the receiving end. Then there was another source of potential interference: CB radio. At first, you were about as likely to encounter a CB operator as a ham radio operator. But then in the 1970s, CB exploded, becoming a cultural phenomenon, and you can hear what a state it was in by watching the contemporary TV report in the video below. This explosion of operators who did nothing more than apply for a license (if they even bothered to do so) and bought their equipment at a local store had no idea how to help curb interference, even if they wanted to. In 1977, the AP reported that 83% of the FCC’s TV interference complaints involved CB radio. Early computers were also very noisy on the radio bands. So much so that early attempts at computer audio output were simply modulating the radio frequency interference. Again, at first, this wasn’t a huge problem. But as computers became more common, so did computer-related interference, and the FCC didn’t want to deal with another CB radio-style explosion. The rest is, as they say, history, and [Ernie] covers it all in the post. Getting a product approved by the FCC isn’t trivial, but if you have to do it, we have some advice. Blog – Hackaday Read More
FRIDAY EDITION: I went from no leaves to being knee deep in leaves in just one night! The winds howled last night on the island and now I have some work to do! Another week and I will have a beautiful ocean view for the winter....I hate to bring up 7200 but who is the asshole who broadcasts all day with the foul mouth? Is the FCC deaf? Local Ham Radio Operators Help Keep Thruway Safe During HalloweenIt’s almost Halloween — and that means it’s time for the Pumpkin Patrol! Amateur radio operators — or “Hams,” as they like to be called — from the Drumlins Amateur Radio Club in Wayne County and the Skenoh Island Club in Ontario County are teaming up once again with State Police Troop T for the 49th year of this Halloween tradition. These volunteers will be stationed on bridges over the Thruway tonight and Friday night, keeping an eye out for any tricks that could turn dangerous — like vandalism or debris being thrown onto cars. They stay in touch with a central coordinator, who can alert 911 in seconds if anything suspicious pops up. Drumlins Club President Dave Taylor says Hams all across New York will be out there helping to keep drivers safe — and it’s worked: there hasn’t been a single serious vandalism incident on the Thruway since the Pumpkin Patrol began nearly five decades ago. Ham radio offers St. Joseph School students lessons in science, math and communication
“CQ, CQ, CQ, school roundup. This is kilo charlie zero lima kilo victor.” A St. Joseph School student released the button on the side of the ham radio’s microphone. Within seconds came a response through the radio’s crackle. “This is kilo foxtrot three delta juliet,” the man on the other end of the receiver called out. Andrea Nunziante took over the microphone, introducing his new contact — Ronald Reiff (KF3DJ), a retired radio announcer from Columbus, Pennsylvania — to students at St. Joseph in Cottleville, who eagerly watched the amateur radio demonstration. On an October afternoon, students took turns contacting other ham radio operators across the country as part of the American Radio Relay League’s School Club Roundup, a twice-yearly event for ham radio clubs at elementary, junior high, high schools and colleges that gives them experience exchanging information with other amateur radio stations. Nunziante, St. Joseph’s technology director and an amateur radio operator (KCØLKV) for more than 25 years, introduced students to ham radio this school year to show how the technology can connect people in new ways. Lessons in math, science and language arts have also emerged from their discussions. “It is cross-discipline because you can use it for geography, you can use it for language, you can use it for science,” he said. “So there are several ways that the teacher can integrate that into the curriculum. The overall goal is to get them interested in a way of communication that it’s different than cellphone and computer.” Students have learned basic radio concepts, including frequencies and propagation (the way some radio signals travel from one amateur radio station to another), and operating etiquette when contacting other hams. Connecting with other amateur radio operators depends largely on solar and weather conditions, Nunziante explained to about two dozen students who stayed after school to participate in the roundup event. The occurrence of a solar flare — a burst of radiation from the sun’s surface caused by the release of built-up magnetic energy — can interfere with high-frequency signals, causing a sudden loss in communication. “When there is a big magnetic flare and you turn on the radio, it’s just quiet — really quiet,” he said. Seventh grader Joey Risley made contact with a radio operator at Red River Gorge, Kentucky, who was participating in Parks on the Air, a program that promotes communications from national and state parks. “It’s really cool that you can talk to people, it’s just really fun,” said Joey, who plans on exploring more with ham radio as part of a Scouting merit badge on radio. “It’s a new perspective, just like talking on the phone. We do that every day. But this is a bit more like, you don’t know who you’re going to talk to next or where they’re from. So I just find it really exciting.” Throughout the afternoon, students made contact with ham radio stations in other states, including Oklahoma, South Dakota and Texas, as well as one in Canada. Nunziante explained that proper etiquette involves listening before transmitting, avoiding monopolizing a frequency and being respectful of other operators. CQ (pronounced “seek you”), for example, is a general call used by an operator to invite other stations to make contact. “Is the frequency open?” Nunziante called into the microphone. Turning to students, he said, “Let me ask you a question: Do you know why I did that? I’ll show you,” as he walked over and wedged himself in between two students sitting on a bench. “Was that good? No. But if I come over and say, ‘May I come over and join you in this seat?’ That’s polite, right?” Students made contact with Andrew Piper (KI5AIE), an 80-year-old operator from Calera, Oklahoma. Fourth grader Marianna Dwyer asked him what he likes most about ham radio. Piper told her that he enjoys taking apart radios and putting them back together and has been a ham radio enthusiast since he was 10 years old. Nunziante hopes the school eventually will form a ham radio club and apply for a club station license. But for now, he hopes that students will grow in their enthusiasm for ham radio. People have told Nunziante that ham radio generally attracts older enthusiasts, but he said it’s really a hobby for any age and is easy to learn. “This is something that the kids can actually do,” he said. “You start with the tech class (entry-level license), and then you can go out from there.” What is Amateur Radio?It is a form of communication, a hobby, a community service and a vital service in the event of an emergency. It could be a teacher in Nova Scotia making friends over the radio with another Radio Amateur in New Zealand; an Alberta teenager using her computer to upload a chess move through her radio which is retrieved by a fellow chess fan in Florida via an Amateur Radio space satellite; or a truck driver in Manitoba contacting Radio Amateurs in a hundred countries during a single weekend contest. The appeal of Amateur Radio is the ability to communicate across the country, around the globe, and even with astronauts on space missions. Many Radio Amateurs build and experiment with radio. Do you?
If you answered maybe or yes to any one or a few of these questions, then Amateur Radio may be for you! New Book Release: Small Antennas for Small Spaces 3rd EditionAmateur radio operators love antennas — the bigger the better — but if you don’t have acres of property to erect the antenna of your dreams, it doesn’t mean you’re effectively off the air. Ham radio is still yours to enjoy. It’s just a matter of making the right antenna choices to improve your chances of success. The third edition of ARRL’s Small Antennas for Small Spaces by Steve Ford, WB8IMY, is a valuable resource for amateurs who live in apartments, condominiums, or houses on small lots. Filled with practical advice, this book guides you to finding the right antenna design to fit the space you have available. You’ll find ideas and projects that will get you on the air regardless of where you live! THURSDAY EDITION: Good morning...Rumor has it the new 7300 receiver is what you find in the current 7610, not bad Today we received exciting information from Icom regarding the price of the new Icom IC-7300MK2!

Hurricane Melissa UpdateHurricane Melissa, now a Category 1 storm, is expected to approach the island of Bermuda late Thursday afternoon. The Hurricane Watch Net ended operations Wednesday night and are now at an Alert Level 3 standby mode. They will continue to closely monitor Melissa’s track, forward speed, and intensity. Should conditions warrant, they will resume operations for a potential threat to Bermuda on Friday. The VoIP net is also in standby mode. Amateur radio operators were busy on Wednesday monitoring the hurricane nets and relaying messages throughout the day. The National Weather Service is expected to issue a new forecast at 8:00 AM Thursday. Updated Wednesday, October 29, 2025 @ 5 AM EDT Hurricane Melissa is moving over Eastern Cuba after making landfall late last night. Now a Category 2 Hurricane, it’s bringing damaging winds, flooding rains, and dangerous storm surge. At 5:00 AM EDT, Melissa is expected to move across the southeastern or central Bahamas later today, and pass near or to the west of Bermuda late Thursday and Thursday night with winds now at 115 miles per hour. WX4NHC, amateur radio station at the National Hurricane Center, remains active and will be on-the-air on the Hurricane Watch Net frequency 14.325 MHz most of the time and 7.268 MHz depending on propagation. The VoIP Hurricane Net was activated on Monday and is expected to remain active until late Wednesday evening. The National Emergency Network of the Cuban Radio Amateur Federation (REN-FRC in Spanish) is also active through station CO9DCN, from the National Civil Defense Staff. Cuba. Amateur radio operators are continuing to monitor the weather nets and are relaying information, as necessary. ARRL will have updates as the situation develops and Hurricane Melissa continues its path northwestward Operation HELO, Triad HAM radio operator step up to help Jamaica after Hurricane Melissa tears through islandSTOKESDALE, N.C. — As Hurricane Melissa pounds Jamaica with dangerous winds and torrential rain, some in the Piedmont Triad are already stepping up to help from hundreds of miles away. While most people steer clear of disasters, groups like Operation HELO move toward them. The rapid-response relief organization was created in the aftermath of Hurricane Helene, and its leaders say Melissa is bringing back familiar concerns. “Unfortunately, there are some similarities with Hurricane Helene and Hurricane Melissa,” Eric Robinson, executive director of Operation HELO, told WFMY News 2. Melissa is expected to bring not only damaging winds, but extreme rainfall to the island nation. “I think they're calling from anywhere from 30 to 40 inches, and that's what the mountains of North Carolina saw,” Robinson said. Robinson said Jamaica’s mountainous terrain could create similar hazards to what western North Carolina experienced during Helene. “They're gonna see a lot of flooding, a lot of flash flooding, a lot of landslides like we saw during Helene,” he said. During Helene, Operation HELO used helicopters to reach stranded communities in the mountains. But this time, Robinson said getting a helicopter into Jamaica is too risky. Instead, the organization will help coordinate aid from the U.S. once airports reopen, sending supplies by ship or plane. “Obviously, during Hurricane Helene, they were our neighbors, but when we start looking at it from a global aspect, these are also our neighbors as well,” Robinson said. Others in the Triad are also helping from afar. Mark Nadel of Stokesdale operates a ham radio from his home, allowing him to connect with people in Jamaica as other methods of communication fail across the island. “I have my own generators, I have my own antennas, I have my own equipment. In the event power goes out, I don't need anybody else to be able to communicate,” Nadel said. “So, and that's the same thing that's going on down in Jamaica right now, most of the power is out but stations that we're talking to have their own generating systems and it doesn't take a whole lot to run it.” On Wednesday, he spoke with the National Weather Service at a Jamaican military substation — helping assess damage and connect people with shelters and hospitals. “People always want to do something but you can't get there and do it and this gives me the ability to really participate and kind of give back,” Nadel said. As conditions slowly improve, both men say their work is just beginning. Robinson’s team is preparing to move supplies in as soon as it’s safe, and Nadel hopes to help reconnect families on the island. Both say that in the worst storms, connection and compassion can make all the difference.
WEDNESDAY EDITION: The U.S. tried permanent daylight saving time—and hated it, this is an interesting read....I listened to the hurricane net on 20 meters yesterday, not much info of any interest while I was listening.... If China declares war, these ham radio enthusiasts could be crucialTAIPEI, Taiwan — On Tuesday nights, BX2AN sits near the Xindian River, motionless but for his thumb and middle finger, rhythmically tapping against two small metal paddles. They emit a sound each time his hand makes contact — from the right, a dit, or dot; from the left, a dah, or dash, the building blocks of the Morse code alphabet. “Is anyone there?” he taps.
The replies come back in fits and starts: from Japan, then Greece, then Bulgaria. Each time, BX2AN, as he is known on the radio waves, jots down a series of numbers and letters: call signs, names, dates, locations. Then he adjusts a black round knob on his transceiver box, its screens glowing yellow in the dark. There can be no doubt that this is his setup. That unique call sign is stamped across the front of his black radio set, scrawled in faded Sharpie on his travel mug and engraved in a plaque on his car dashboard. On the edge of his notepad, he’s absent-mindedly doodled it again, BX2AN. In the corporeal world he is Lee Jiann-shing, a 71-year-old retired bakery owner, husband, father of five, grandfather of eight and a ham radio enthusiast for 30 years. Every week, he is the first to arrive at this regular meeting for Taipei’s amateur radio hobbyists. They gather on a small, grassy campground on the city’s southern border, where Lee hunches over his radio from the back of his van, listening to the airwaves as the sun goes down. He doesn’t talk much; he prefers the dits and dahs to communicate. By 8:30 p.m. he has corresponded with six other operators in various countries. U-R-N-A-M-E, Lee asks a contact in Bulgaria. G-E-K, the operator replies, adding a location, S-O-F-I-A. Lee taps out L-E-E, and his city in response. As more members of the Chinese Taipei Amateur Radio League, or CTARL, trickle in, two other operators are setting up stations several yards away. One of them, like Lee, starts tapping. The other prefers a handheld voice transmitter, tuning into some indistinct chatter across the Taiwan Strait. In the age of smartphones and DMs, amateur radio has become a niche hobby in Taiwan. Participants like Lee, many of whom are older than 50, tinker with electronics, exchange postcards with new contacts and compete to see who connects with the most far-flung places. But ham radio might turn out to be more than just a pleasant pastime. The self-governing island, about 100 miles east of China, is weighing wartime scenarios in the face of growing military aggression from its vastly more powerful neighbor. If cell towers are down and internet cables have been cut, the ability of shortwave radio frequencies to transmit long-distance messages could become crucial for civilians and officials alike. The recreational use of wireless radios, which transmit and receive messages via electromagnetic signals, became popular in the early 20th century, starting in the U.S. Since the federal government began issuing licenses in 1912, the number of noncommercial radio operators in the country has surpassed 846,000, according to the Federal Communications Commission. Amateur radio operators (also known as “hams”) tend to use the high radio frequencies, a measure of the oscillation rate of electromagnetic waves. Such shortwave radio signals are able to traverse great distances by bouncing off particles in the Earth’s atmosphere. (Never heard of it? Ham radio still occasionally pops up in movies and TV — “A Quiet Place,” “The Walking Dead” — as a communication channel of last resort.) The technology proved useful during World Wars I and II, when countries such as the U.S. and Britain limited civilian airwave activity but enlisted skilled hobbyists to help send and intercept covert messages. More recently, during Russia’s invasion of Ukraine, the BBC used shortwave radio to broadcast its news service after communication towers were attacked. Ham radio operators were also able to listen in and interrupt communications among Russian soldiers. FULL STORY

Ham Radio’s Most Ambitious DXpedition to Remote Bouvet IslandFew places on Earth are as inaccessible—and as coveted by amateur radio operators—as Bouvet Island. Located in the South Atlantic, this uninhabitable rock has long been regarded as the “Mount Everest of DXpeditions.” According to the DXCC Most Wanted List, Bouvet ranks near the very top of sought-after contacts, making every attempt to activate it a historic event. With renewed momentum after a 2023 attempt, the 3Y0K team is back, bringing with it high stakes, innovative planning, and rigorous safety protocols. What does it take to run one of the most ambitious ham radio DXpeditions in history—on one of the harshest and most dangerous islands on the planet? In the second installment of this special coverage from Radios in Action by Icom, host Ray Novak, N9JA, Senior Manager at Icom America, speaks with Cezar Trifu, VE3LYC, Co-Leader of the DXpedition. Together, they dive into the complex logistics, safety planning, and behind-the-scenes infrastructure that make the 3Y0K activation of Bouvet possible.

Everything You Ever Wanted to Know about the Manhattan Project (But Were Afraid to Ask)There have been plenty of books and movies about how the Manhattan Project brought together scientists and engineers to create the nuclear bomb. Most of them don’t have a lot of technical substance, though. You know — military finds genius, genius recruits other geniuses, bomb! But if you want to hear the story of the engineering, [Brian Potter] tells it all. We mean, like, all of it. If you’re looking for a quick three-minute read, you’ll want to give this a pass. Save it for a rainy afternoon when you can settle in. Even then, he skips past a lot of what is well known. Instead, he spends quite a bit of time discussing how the project addressed the technical challenges, like separating out U235. Four methods were considered for that task. Creating sufficient amounts of plutonium was also a problem. Producing a pound of plutonium took 4,000 pounds of uranium. When you had enough material, there was the added problem of getting it together fast enough to explode instead of just having a radioactive fizzle. There are some fascinating tidbits in the write-up. For example, building what would become the Oak Ridge facility required conductors for electromagnets. Copper, however, was in short supply. It was wartime, after all. So the program borrowed another good conductor, silver, from the Treasury Department. Presumably, they eventually returned it, but [Brian] doesn’t say. There’s the old story that they weren’t entirely sure they wouldn’t ignite the entire atmosphere but, of course, they didn’t. Not that the nuclear program didn’t have its share of bad luck. Blog – Hackaday Read More Important Notice: Keep Clear of Emergency Frequencies During the Contest WeekendTropical Storm Melissa is nearly stationary in Caribbean on Friday, October, 24, 2025. Forecasters warn it could quickly intensify, impacting Jamaica as a hurricane and causing catastrophic flooding and landslides Haiti and the Dominican Republic. The Hurricane Watch Net (HWN) a group of licensed Amateur Radio Operators trained and organized to provide essential communications support to the National Hurricane Center during times of hurricane emergencies, is carefully monitoring the storm’s development. Important Notice: Emergency Frequencies — Keep Clear During Contest Weekend As the Caribbean faces potential hurricane impacts, IARU (International Amateur Radio Union) Region 2 has activated emergency nets on the following frequencies:

eam Fear is at it again. For the past 11 years, this dedicated group of researchers with a very cool nickname has conducted the annual Chapman University Survey of American Fears. This year, they surveyed 1,015 adult Americans on what they fear most, from sharks to heights to identity theft. Wondering which fear took the first slot? For the 10th consecutive year, corrupt government officials topped the list. Fears of a loved one becoming seriously ill, economic or financial collapse, and cyber-terrorism followed. Here’s the full list of what Americans fear most in 2025:
Michigan terminates controversial EV battery plant and seeks to claw back millions in incentives...another failure...LANSING, Mich. (AP) — Michigan is demanding millions of dollars in incentives back from a Chinese company after plans to build an electric vehicle battery plant collapsed following years of pushback against the project from neighbors and members of Congress. Democratic Gov. Gretchen Whitmer supported the $2.36 billion factory in 2022, and state lawmakers approved nearly $175 million in incentives for the project. The state is now holding Gotion Inc. in default of $23.6 million, accusing the company of abandoning the project.
“While this is not

Atomic
Leisure
— Las Vegas,
Nevada, 1955
On July 17,
1955, at
precisely
5:30 a.m.,
swimmers at
the Desert
Inn pool in
Las
Vegas paused
mid-dive. A
mushroom
cloud rose
in the
distance—65
miles away
at the
Nevada Test
Site. The
atomic
blast, part
of Operation
Teapot, was
visible from
the Strip,
and locals
had gathered
with lawn
chairs and
sunglasses
to witness
the
spectacle.
Children
floated on
inflatable
rings,
couples
sipped
coffee, and
lifeguards
pointed
skyward. The
juxtaposition
was surreal:
leisure and
annihilation
sharing the
same
horizon.
For many, it was a symbol of American optimism, blind to the dangers of radiation. For others, it was a haunting reminder of the Cold War’s reach. That morning, Las Vegas became the only city in the world where you could sunbathe beneath a nuclear sunrise. Give Your Twist Connections Some StrengthWe’ve all done it at some time — made an electrical connection by twisting together the bare ends of some wires. It’s quick, and easy, but because of how little force required to part it, not terribly reliable. This is why electrical connectors from terminal blocks to crimp connectors and everything else in between exist, to make a more robust join.
But what if there was a way to make your twist connections stronger? [Ibanis Sorenzo] may have the answer, in the form of an ingenious 3D printed clamp system to hold everything in place. It’s claimed to result in a join stronger than the wire itself. The operation is simple enough, a spring clamp encloses the join, and a threaded outer piece screws over it to clamp it all together. There’s a pair of 3D printable tools to aid assembly, and a range of different sizes to fit different wires. It looks well-thought-out and practical, so perhaps it could be a useful tool in your armoury. We can see in particular that for those moments when you don’t have the right connectors to hand, a quick 3D print could save the say. A few years ago we evaluated a set of different ways to make crimp connections. It would be interesting to subject this connection to a similar test. Meanwhile you can see a comprehensive description in the video below the break. HAMS YOU MIGHT KNOW- ALIVE AND SK K1TP-
