[PSUBS-MAILIST] OTS comms headset.

Fri Nov 20 16:50:48 EST 2020

Cliff, I have a spare headset that I am using for parts. It will be a
perfect test rig for your idea which I like a lot. The vhf radio I have in
the SeaQuestor unfortunately does not have a removable mic chord, so I will
have to play around with the wiring a bit. I might be able to wire the
switch in my flight stick which has a toggle feature on one of the
switches. Time to build a test rig.

Best Regards,
David Colombo
