[Elecraft] K2 No SSB out

[Don Wilhelm]

David,

Does this K2 produce power in CW mode?  I cannot tell from your post 
whether you have an SSB audio problem or whether you have an RF transmit 
problem - more information is required.

If you do have output in CW mode (or TEST), then the following questions 
are relevant.

Do you have bias voltage (+5V) on pin 1 of the mic connector?

Did this MH2 microphone work with this particular K2 before?  If you are 
not certain, look at the plugging for the microphone configuration 
header - for the Elecraft pinout, all connections should be straight 
across the header and there should be a 5.6k resistor between pins 1 and 
6 on the back of the mic jack.
