  • Knots for ham radio
    When I was a kid, a friend of mine tried to get me into Boy Scouts. The first thing that they tried to teach me was how to tie knots. At that point, I wasn’t really much of an outdoors type, so the utility of knowing how to tie a variety of knots was lost […] The post Knots for ham radio (...)

  • Programming is hard
    I own a FlexRadio 6400, and overall, I’m quite happy with it. It’s probably the best-performing radio that I’ve ever used, Having said that, it’s not perfect. Recently, Flex released an update to SmartSDR, and for some folks, the update caused their radios to quit working. This appears to be (...)

  • Badger me…….please
    I’ve often thought that hams should do more with badges, like they do at DEFCON and other hacker conferences. I had some ideas of designing my own, but then I found out about the Pimoroni Badger. The Badger is a very cool, hackable, programmable badge with an e-ink display, with a Raspberry Pi (...)

  • Another crazy idea for an amateur radio video
    A couple of weeks ago, the Veritasium video, “The Big Misconception About Electricity” created quite a stir. If you’re interested in the physics of electricity, you might want to watch this yourself. I’m not going to discuss the technical merits of this video here (although feel free to do so in (...)

  • Would paralleling diodes make a crystal radio work better?
    On the amateur radio subreddit, some guy posted a link to his ePay store where he’s selling fancy crystal radios. Since there’s a rule that you can’t post ads, his post was quickly removed, but not before I clicked on a link and got a look at his work. Honestly, some of it looked pretty (...)

  • ARRL actually starting to do things for clubs
    If any of you have read my blog over the years, you know that I’m often critical of the ARRL’s efforts to help affiliated clubs. Even so, hope springs eternal.

  • How diverse is your club? How diverse should it be?
    One of the knocks on amateur radio is that it’s not very diverse. While that’s not completely true, I do think that we could do a better job of being more inclusive. Being more diverse and inclusive could well be a way to strengthen already good clubs and help failing clubs stave off extinction. (...)

  • FCC to start looking at receiver specs
    As hams, we are aware—or should be aware—of the spectral purity requirements spelled out in the Part 97 rules (§ 97.307). The purpose of these rules is to prevent unintentional interference.
