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…

Omnibus and variorum in K minor, Op. 7_1beta
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…

K6ARK Mini Mic kit for the (tr)uSDX
Next-to-last (for now) in the current series of kit-build posts, the K6ARK Mini-Mic: Time for a functional test! This mic has lots of nice features like being tiny and lightweight; another one that I plan to take advantage of is that it uses a standard double-ended 3.5 mm 3 conductor cable. My next project will…
