[Elecraft] Back to the SSB board

[Ian J Maude]

Hi all,
Well I have finally started looking for the fault on my SSB board after 
about 9 months!  For some reason I have no receive when the board is 
plugged in.  If I short out pins 1 and 3 of J9 and J10 I get receive no 
problem, so it would appear to be a fault on the SSB board.
I have checked the crystals to ground, all seems OK.  I have checked the 
voltages on the pin diodes and again, all would seem well.  In fact, 
other than a few small stray voltages, the only major anomaly I can find 
is a voltage on U4-3 of 6V on receive.  The manual states 0.6 volts.
I would love any thoughts to point me in the right direction please?

73 Ian
