There is no escape from the fact that Ham Radio might be an expensive hobby. This is why I am really grateful to folks like G0UPL and WA3RNC who come up with affordably priced kits so new hams may try SOTA without having to break their piggy banks.

While I am a huge fan of QCX-mini with only 3 watts out I find it a bit underpowered and lacking band agility - QCX is a single band transceiver. I was in a situation a couple of times when an antenna farm on the summit of a mountain I was trying to activate was making a lot of noise on either 40 or 20 meter band forcing me to use the other one. On top of that 20 and 40 meters band signals propagate differently. Switching bands allows you to shift zones where your signals are heard so you may reach folks who were in a shade on another band.

This is why as soon as I heard about TR-25 - 5 watt CW-only 20/40 meter transceiver kit I was sold on immediately. Just in case - I’m not sponsored by WA3RNC in any way and paid a full price for the kit.

Hans G0UPL made yet another addition to the family of QCX transmitter kits. QCX+ is good as I wrote previously but QCX-mini is even better!

I was not lucky enough to get my hands on the kit from the very first batch but patience is gold. On a bright side revision 2 PCB I received does not require a hack with an additional capacitor in parallel with C38.

I’ve received the kit, built it and I love this tiny rig!

Same way as with my previous post I will try to avoid repeating the excellent build and operating manuals but I do have a few nits to pick.

Bonus: WSPR beacon mode test.

Hello friends! Not a SOTA activation report this time. I took a break and spent some time with a soldering iron in my hands!

SOTA is not only about hikes and operating radios but also about building your rigs and antennas. When a heap of dead and cold components turns into a radio one can use to make contact with people hundreds miles away it is pure magic. This never gets old. So I couldn’t be happier when Hans G0UPL announced he’s updating his excellent QCX transceiver kit.

I’ve immediately pre-ordered the upgraded version.
