That's excellent advice from Gary!  With #1361 I was failing the TX
Gain Calibration on 60m only.  I found one toroid had exactly the
problem he describes (looking from the component side of the board).
I took an X-Acto knife, scraped the toroid leads to expose bare wire
and resoldered from the component side, which fixed the problem.
