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 100uf 16v electrolytic, vertically rather than flat against the board. It says “lay down” right on the board, but there it is.
Finally I came to the transformer that lies at the heart of the meter, wound on a binocular core:
Once that was finished, there were only a few parts remaining; two BNC connectors, the 7-segment LED display, and inserting the microcontroller chip. Install a 2032 battery and turn on the power; display shows — . — , which indicates “no input”, and is normal. Smoke test passed!
Now for a quick test of function! I got the (tr)uSDX with its battery pack and a BNC jumper, ran through the radio’s function menu, and tried it out:
Looking forward to taking both of these devices into the field for an activation soon!
