  • Operating notes: New CW ops edition
    I’m hearing some new ops on the CW bands these days, and I think it’s very cool. I’m not sure what’s motivating them, but whatever it is, I’m all for it. Here’s one email I got from a fellow after our QSO: Dan, I’m a new CW operator and I heard your call tonight and (...)

  • Operating Notes: I’m twitch-y, bye-bye X-6100, bring on the toroids
    I’m Twitch-y! Last night, I worked Luis, EA1TG, and this morning, he sent me a link to a video on Twitch that he made of our contact. (Click on the image to go to Twitch. For some reason, I couldn’t embed the Twitch video here.) This is kind of cool. I’ve been thinking of setting (...)

  • Hamfests are as much about meeting people as they are about selling stuff
    Yesterday, my friends Paul KW1L, Rick K8BMA, and I drove down to Toledo for the Toledo Mobile Radio Association (TMRA) hamfest. This is generally a well-attended event, so I schlepped a bunch of stuff down there. Some of it was my junk, some of it odds and ends from the estates I agreed to (...)

  • Handmade QSLs from the 1930s
    My brother, Mike, runs an estate sale company, Metro Detroit Estate Sales (shameless plug intended). From time to time, he’ll call me when a sale he’s conducting includes some electronics or ham radio gear. A couple of months ago, he called and said that this most recent sale included a bunch of (...)

  • Inclusivity in Amateur Radio
    This is a guest post by Bud Talbot, W0RMT, and is cross-posted from https://w0rmt.net/. Recently, my ARRL membership was up for renewal. I thought about it for a long time, and finally decided to renew so that I could have a (very small) voice in the way the League is operating these days. (...)

  • Amateur radio in the news: New club edition
    In my news feed this past month, there were two announcements of new amateur radio clubs being formed. I’m not so sure how often that happens anymore, so I thought I’d spotlight them here.

  • Random stuff: Even MIT gets it wrong, DIY Layout Creator, Astron power supplies with PowerPoles
    Even MIT News gets it wrong In a recent article, MIT News reported on a recently-developed tamper-proof ID tag. The gist of the story is that some researcher at MIT has developed a system that irradiates a small tag with THz waves and uses the reflections from the tag to identify an object. In (...)

  • Operating notes: CB0ZA, poor fists, Cherry Valley
    CB0ZA A couple nights ago, I turned on the radio and could see two big pileups on 30-meter CW. Down towards the lower portion of the band, there was a big pileup, and up towards 10120 kHz, a decidedly smaller one. So, I fired up DX Summit, the DX spotting website, to see what was (...)

  • Introduction to the KB6NU Pico Keyer Project
    In the May 2023 QST, K1SWL published the article, “A Simple Morse Memory Keyer by Dave Benson, K1SWL. I found it to be an interesting project, mainly because it used the Raspberry Pi Pico microcontroller. I like the Pico because it has more memory and is faster than most Arduinos. I thought to (...)

  • ARRL Board postpones action on bylaws change
    I guess the board got the message that the members didn’t like the bylaws change that was proposed. A couple of hours ago, an ARRL Member Bulletin appeared in my inbox reporting on the board meeting that was held Friday and Saturday. Here’s what it says: ARRL Board Approves Free Membership for (...)

  • The ARRL Board is at it again!
    A couple of weeks ago, I posted the agenda for the upcoming ARRL Board Annual Meeting. As agendas go, this one had very little content. Well, I recently found out why. There are some very controversial items on the agenda, and I can only surmise that whoever published the agenda didn’t want the (...)

    Here are the two latest additions to my collection of QSL cards from stations whose callsigns spell words. I interviewed Glenn, W4YES, for Episode 405 of the ICQ Podcast in June.

    Olivia I just made my first Olivia contact. The biggest hurdle was getting fldigi to work with my IC-7610. When I first ran fldigi, it received just fine, but I couldn’t get it to transmit. One of the problems was that, for some reason, there’s no official fldigi RigCAT XML file for the IC-7610, (...)
