JD, Mike, et al,
Bob, NK9M connected a dummy load to the lowfer and the slash code
waveform then looked fine, proving the clipping when live was caused by
RF coupling to the dead-bug op amp circuitry. He then tried placing a
steel plate between the beacon box and the antenna and managed to get
the dots looking correct again. Dashes are still poor but Bob will try
repositioning the plate to see if they can be returned to normal too.
