[Elecraft] Help needed on K2/100

[Don Wilhelm]

Ron,

Because you can hear your own audio when you talk into the mic, I 
suspect that you could have the K2 menu set to SSBA bAL - it will do 
exactly that with the menu setting, it feeds part of the signal back 
into the receiver.  It is usually used for nulling the carrier balance.

Also check to see if the display "L" or "U" is blinking - if so, you 
have inadvertently set the K2 to VOX - Hold the VOX button several times 
until you see Ptt in the display.

If neither of those conditions exist, then please tell us and ask again.

73,
Don W3FPR

In receive, pin 6 has approximately 6 volts on it and with PTT activated on the microphone, it drops to zero.  However, no relays click and no RF out appears in the display.  The rig continues to receive any signal it is tuned to but I can hear my own audio over that signal if I talk into the Mic.  So, I conclude the SSB Adapter is processing the audio signal from the mic, but where do I check next to see why it isn't triggering the transmitter?  Any ideas appreciated.  BTW, "Tune" works fine with output matching whatever level the display is showing.
