it would only take a small number of additional
components (and software) to make some sort "peak
detector" such that the resonance of each PA stage
inductor can be checked while building.
While thinking about your suggestion, I had another
thought. How about connecting a dummy load and sweeping
a range of frequencies to see where max power was and
using the results to determine what needed to be removed?
Of course, this does mean completing the build first.
I have my first (80 M) QCX nearly built. I still have to
wind the toroids, but I've left the BNC connector, volume
control, rotary encoder, push buttons and jacks off as my
intention is to put it in a QRP Labs aluminum enclosure.
