[TenTec] Omni V deaf and won't transmit on 20m

[Peter Bertini]

If it was working, and suddenly died after you have opened the case I'd
suspect one of the cables that controls the relay selection for the band
filters.  88% percent chance that reseating cables will cure the problem.

BTW, which panadapter are you planning on using?  I just ordered an IF
buffer board from Clifton Labs which will be used with a L-Pan and 192 kHz
soundcard.
