  • Finishing the (tr)uSDX amplified speaker

    June 24th: To quickly recap, the story begins here, and is continued here. All it took, in the end, was actually sitting down at the bench and (gasp!) actually working on it for maybe 40 minutes; I had the last remaining part, an input jack, right there. Finding one was the last thing I did…

  • April omnibus post

    Spring is getting pretty firmly established here; though we are still getting some light overnight frosts, the daytime temperatures can get into the 60s. The lakes and streams are still low; we need more rain! Home DIY is taking up a lot of time, and the expanded garden is making increasing demands. I managed to…

  • A hike around Camel Bluff, and an amplified speaker for the tr(u)SDX

    On Saturday I was en route to the nearest Aldi store and realized I would soon be passing by Mill Bluff State Park, which quickly led to trying to remember the last time I had hiked the Camel Bluff trail, or any of the other hikes at this small-but-fun park … I still have no…

  • Mid-March omnibus

    A summary of what’s been happening lately Tomorrow (the 19th) is the first day of Spring! Astronomical Spring, that is. Meteorological Spring already happened on the 1st; I suppose they do that for consistency in their statistical calculating, makes it easier to just move along and ignore all of that messy real-world stuff. Quick vignettes…

  • Hung a new antenna today!

    It seems like just yesterday I was thinking about getting an antenna up in the trees at home … Now, as the sun sets, I have one! The day started sunny and cold, but after noon sunny was winning and the temperature got up to around 30. I had all the necessary stuff handy (I’ve…

  • A post about many things

    re: Field Day 2023 The December issue of QST arrived a while ago and I invested maybe 15 minutes looking through the fine print for my score: 440 points. I think that my claimed bonus for Public Information Display was rejected; not unfairly mind you, it was a bit skimpy. Eh, surest way to fail…

  • Cut down my knee board today

    When I made this I cut it to fit in a good-sized backpack, never thinking that I might want to use it with any of the smaller packs that I more often use for portable operating; this is why it gets carried hanging outside the pack from a carabiner. Today I had a few moments…

  • Touch paddle project, with updates

    October 24th: I want to start off with a word of praise for UPS; yesterday evening my package was in Louisville KY; this morning at 5:30 it was in Rockford IL; but I lacked faith, I didn’t believe it would get here today … and there it was on my doorstep at 3! Thanks, UPS!…

  • Another mini-mic (lol)

    As I mentioned in an earlier post, I purchased all of the parts needed to make a few more mini-mics to use with other radios. I had one of each sitting out on the benchtop for a day or so while I noodled about what to use to give it some structure … then a…

  • Adapting the (tr)uSDX mini-mic to the X6100

    I posted a few weeks ago about building K6ARK’s Mini-mic kit for the (tr)uSDX, and my plan to adapt it to the X6100 to save weight and pack space, and I have been moving that project forward a little bit at a time. Today I finally had time to try out the result and write…

  • Homebrew EFHW from scratch

    I have been thinking about making a couple of minimalist EFHW antennas with SMA connections for use with the (tr)uSDX. After weeks and weeks of out-of-stock conditions for my preferred kit, I ordered up some parts and started to make one from scratch. Starting with an FT50-43 toroid core, I wound the 49:1 unun: The…

  • projects, projects, projects… so many projects …

    Since I finished off those half-built kits a few weeks ago I have been purchasing a variety of electronic parts to start a new round of projects; here is a representative collection of them, tastefully arrayed in a cardboard flat (which is one of my favored containers for organizing projects on the workbench). I have…
