[Elecraft] K3S MIC Problem

[Bill Rogers W3UL]

I'm guessing that I'm not the first to notice this on the K3S.  I don't do
much SSB but was active in Sweepstakes this past weekend and noted that
occasionally the audio would go dead.  Looking around I found that the MIC
gain had dropped from the usual (about 16) down to zero.  I placed a toroid
around the MIC cable and this seemed to prevent the problem most (but not
all) of the time.  The MIC cable (and the K3S) both sit next to an Alpha
87A amp.  I don't recall reading about this. Is some protective function
being activated?
