I don't know if this is applicable or not--but--- 1) Do you have anything connected to pin 1 of the ACC socket?
Keep in mind that if the audio level on pin 1 is "too high" the PTT doesn't work. This is readily evident when using a TNC where the audio level is too high; the TNC tries to PTT, but the rig won't key. 2) A different thought---maybe the microphone audio is muted when the rear ACC socket is keyed. That is common so as to keep from having a "hot mic" when transmitting via a TNC. 73, Mark N8MH At 07:17 AM 1/24/2010 +1100, Tim Tuck wrote: >Hi Bob, > >Pin 3 can not be set to only tx on a specific mode BUT it can be set to >only tx for a specific band.

As always, thankyou 73 Bob W7LRD >_______________________________________________ >Sent via amsat...@amsat.org. Opinions expressed are those of the author. >Not an AMSAT-NA member?
