(tr)uSDX and X6100 at Wildcat Mountain
Well, in accordance with my last post there seemed to be nothing left to try but to take the (tr)uSDX out to a park and try it on a resonant antenna, and the next day seemed to be free, so it was up before dawn to make coffee and sandwiches, load the car with radio…

Experimenting with FT8CN and the (tr)uSDX
I think it was over at the forum at DL2MAN’s (tr)uSDX site that I read a post about FT8CN, an Android app (written by BG7YOZ) for the FT8 digital mode, which recently acquired the ability to do CAT control and audio over the USB connection of the (tr)uSDX. I have thought about operating digital modes…

A day at Wildcat Mountain
I mainly went out to Wildcat Mountain to test and adjust my wire antennas, so I brought a couple of radios, all of my antennas, and a variety of test equipment. I set up just off the upper parking area near one of the trailheads of Old Settler’s Trail, which is one of my favorite…

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…

Back in the field (at last!) – Wildcat Mountain, K-1480
It was 7:44when I pulled into the only partly-shaded space in the upper lot at Wildcat Mountain State Park; I shut off the engine and thought “let’s see if I can be set up and on the air by 8:00!”. By 7:55 the 17′ whip was up on the Buddipole and I was turning on…

Building the QRPGuys Digital Power/SWR Meter w/Dummy Load
Next up in my series of kit builds; the QRPGuys Digital Power/SWR Meter w/Dummy Load: QRPguys kits have excellent instructions, and as soon as it arrived I printed them from the website. I followed them precisely, checking off each component as it was inserted and soldered. I made one minor error; placing c 4, a…

Building the QRPguys Multi-Z tuner kit
Building this kit was good exercise; if it works properly when I try it out in the field it will be entirely due to the truly excellent and detailed instructions that I downloaded and printed from the QRPguys website! Get ready for lots of pictures and discussion as we go through the process! The whole…

Wrapping up some kit building …
The workbench has been developing a backlog of kits that need to be finished; a QRPguys Multi-Z Tuner, a QRPguys Digital Power/SWR Meter w/Dummy Load, and a K6ARK Mini-Microphone are the principal ones (there are others, but … ). QRPguys Multi-Z Tuner This one got stalled right out of the bag! Step one is assembling…
