Dayton Hamvention 2026: Day 3, Friday, May 15 – Forums

May 24, 2026 By Dan KB6NU Leave a Comment

Hamvention 2026 logoThe forums at this year’s Hamvention were pretty good—and I’m not just saying this because I was on the schedule. I spent most of Friday morning cruising the vendor booths and schmoozing with people I know. I stopped by the CWops booth, the Amateur Radio Digital Communication (ARDC) booth, and the Youth on the Air (YOTA) booth. In the afternoon, though, I spent most of my time attending the forums.

The first talk I attended was the Long Island CW Club (LICW) presentation, “Our CW Journeys.” I was interested in this talk because I’m in the process of updating my CW book and wanted to learn more about their process.

The presentation consisted of several “testimonials” from members how they learned Morse code by taking LICW classes and participating in LICW activities. The stories were very intriguing, and kudos to LICW for helping people have fun with Morse code.

Next, I stopped by the “Amateur Radio and the Law” forum to say a quick hello to Fred, K1VR, and Bob, K3RF. I didn’t stop to hear the talk, though, as my next stop was the “Hackers in Ham Radio” forum.

This forum was a panel discussion, led by Jeremy, KD8TUO. The discussion was a bit unorganized, but they did talk about how the hacker and ham radio communities intersect. I think that these two communities should intersect even more, and as part of Ham Radio Village, I’m helping to do that. Hackers are the kind of people that we want in ham radio.

The final forum of the day for me was “The Latest from ARDC: Grants and 44Net.” At this forum, folks from ARDC talked a great deal about their latest development, 44Net Connect. It’s taken ARDC a while to get to this point, but it looks to me like they’ve made connecting to 44Net a lot easier than it has been in the past, and I’m looking forward to see what use hams make of it.

There were also short presentations by a couple of their grantees, including the Digital Library of Amateur Radio and Communications (DLARC) and AMSAT. It’s always great to hear what other grantees are doing. ARDC has made a real difference in amateur radio, and I’m happy to say that it looks like they will continue to do so.

Amateur radio videos: Extreme toroid winding, CW bandwidth, KB6NU on LICW

April 6, 2024 By Dan KB6NU Leave a Comment

Need to wind some toroids?

While I’m waiting for my QRPLabs’ QMX kit to arrive, I thought I’d try to learn something about toroid winding. This video takes toroid winding to a whole new level.

W2AEW on CW bandwidth

Question T8A11, in the Technician Class question pool asks, “What is the approximate bandwidth required to transmit a CW signal?” The correct answer is 150 Hz. The question says “approximate” because the bandwidth depends on the speed at which the Morse Code is being sent.

In this video, Alan, W2AEW, actually makes some measurements to determine the bandwidth of a CW signal.

KB6NU on LICW

A couple of weeks ago, Bob, K4LRC,  asked me to speak to the LICW Portable Ops group about getting better at CW. I guess they ran out of qualified speakers. I don’t know if the group learned anything, but it was fun to speak to the group. TL;DR getting on the air and making contacts is the best way to improve your CW.

Amateur radio in the news: Morse Code edition

January 22, 2023 By Dan KB6NU Leave a Comment

Oddly enough, Morse Code has been in the news lately. Here are three articles that I’ve run across recently……Dan


This article appear in the  January/February 2023 issue of Smithsonian.

Morse Code is Back

For almost 20 years, Steve Galchutt, a retired graphic designer, has trekked up Colorado mountains accompanied by his pack of goats to contact strangers around the world using a language that is almost two centuries old, and that many people have given up for dead. On his climbs, Galchutt and his herd have scared away a bear grazing on raspberries, escaped from fast-moving forest fires, camped in subfreezing temperatures and teetered across a rickety cable bridge over a swift-moving river where one of his goats, Peanut, fell into the drink and then swam ashore and shook himself dry like a dog. “I know it sounds crazy, risking my life and my goats’ lives, but it gets in your blood,” he tells me by phone from his home in the town of Monument, Colorado. Sending Morse code from a mountaintop—altitude offers ham radios greater range—“is like being a clandestine spy and having your own secret language.”

Forget dot com, Americans are making a new dash for Morse code

A few years ago a group of New York ham radio enthusiasts decided to address a glaring problem. “There were not enough Morse code operators on Long Island,” said Howard Bernstein, 70, a retired chemicals importer.

Unfortunately, you have to be a subscriber to The Times to read the entire article. I don’t usually include articles behind pay walls, but I thought this was illustrative of a trend, so I included it here…Dan


I thought that perhaps the military’s experience with the Basic Morse Mission Trainer (BMMT) might have some applicability in teaching amateur radio operators Morse Code. I asked about this on the CWops mailing list, thinking that some of the members might have been trained using this system. While there were a couple, they didn’t think that this would be a good way to teach hams Morse Code. For one thing, the training was very specific to receiving random code groups and not with actually communicating with Morse Code…Dan

Innovation on Morse Code for the US Military

On January 10, 1991, the U.S. Army Intelligence School Devens (USAISD) introduced the Basic Morse Mission Trainer to the 98H Morse intercept operator and 98D emitter identifier/locator advanced individual training courses. This system revolutionized the training of Morse code copying skills for both students and instructors, reducing course attrition, and turning out better trained operators faster.

In April 1985, the deputy secretary of defense had approved the consolidation of all four military services’ manual Morse intercept training at USAISD, located at Fort Devens, Massachusetts. By 1988, consolidated training was in full swing, but instructors struggled with high attrition rates and student burnout in the basic Morse course. Mitigation measures included shortening the training day, standing up a diagnostic laboratory to help identify learning patterns of Morse students, and developing an aptitude test to predict student success in the course.

Perhaps the most significant factor to reducing course failures, however, was the introduction of the Basic Morse Mission Trainer (BMMT) to teach touch-typing and basic Morse code. Developed by Russell Beller and Kevin Mott, two civilian instructors in USAISD’s Morse Collection Department (MCD), the new computer-based system would replace the antiquated Morse Code Trainer (MCT)-4 in use since the late 1960s. The Army awarded a procurement contract to Engineering Research Associates on April 19, 1989 which delivered the new systems in October 1990. Three months later, on January 10, 1991, the BMMT was used for the first time in training.
