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.

Hello 

I am trying to set up my 910/sequencer/amp.  Checking things out before hard 
wiring everything I discovered when grounding pin 3 of the acc socket the radio 
does go to xmit, and will do cw, Â however to send ssb the ptt on the mic has 
to be pushed.  At times I use a Heil head set that has no PTT and I simply 
push the xmit on the radio.  Do I have to pick off the PTT at the mic 
connector?  I am probably overlooking something obvious.  What do you 910 
experts have to say. 

As always, thankyou
