  • 2 product FAILs
    I recently purchased two items that I’ve been disappointed with. They not amateur radio products, fortunately, but they are radio-related, so I thought I’d blog about them.

  • 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. Last year, they hired Mike Walters, W8YZ, and he’s actually started to do things to help clubs. For example, the ARRL has finally started (...)

    Understanding Basic Electronics The Long Island CW Club has turned into much more than a place for hams to learn Morse Code. It really is an online amateur radio club.

  • 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.

    I was puttering around the shack yesterday, putting some stuff away and throwing out stuff that I’ve either finished with or will probably never get back to.

  • Fast cars and superheterodyne radios
    This isn’t strictly amateur radio, but I thought you’d find this amusing… In the evenings, when I’m not on the air or fooling around with some electronics project, I like to watch movies from the 1930s, 1940s, and 1950s on Amazon.
