[Elecraft] [K2] Transmit Audio Problems

[Michael Eberle]

I recently started trying to use my K2 for digital modes and noticed my 
transmit audio seems to have some buzz or him in it.  I never really 
noticed it before on SSB, but if I listen carefully it sounds robotic, 
like talking in front of a fan.  When monitoring the SSB signal on my 
K3/P3, I noticed that the carrier is not fully suppressed.  It is 
adjusted as low as it will go with the carrier balance pot on the SSB 
board.

Do I have my filters set incorrectly or should I be checking for 
assembly errors such as toroids wound wrong, wrong component values, or 
bad solder joints?

Thanks,
Mike
