I have a tm-g707
I'm looking for a simple way to wire external switch for ptt whilst driving
The 6 pin mini din connector on front does work the ptt by grounding pin 3
But this also mutes the mic
Any help/advice apreciated
Thanks Barrie

Most modern amateur mics are a TACT switch or microswitch.
Simply bring a couple of wires off the internal switch, ideally wire them to a 3.5mm jack socket on mic case, and then a lead to external switch.
But why would you want to? Have you got mic hanging up in front of your mouth??
I am confused
