µBitx v5 power testing with the ATU 100

So, after finishing up my ATU 100, it was time to … you know, actually use it. As I got the ATU 100 to pair up with my µBitx v5, this is what I used to test. Output was into the previously built dummy load, ran two batches of tests: first with 12V into the µBitx, second with 13.8V. As expected, the power is higher with 13.8V.
