Hi...
The PTT feature quite working on my K2/100. I've checked the circuit up to U1
on the SSB Adapter and it appears OK. 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.
