A24,
headset adapter OPC-499
(http://www.spinnerspilotshop.com/cgi...html?E+scstore)
and this PTT: http://www.mypilotstore.com/MyPilotStore/sep/3313
work the way you'd want them to.


Thanks, Tom & Ron!

I have that exact headset adaptor. I noticed in the manual that the
PTT simply closes a loop, so the Icom PTT's sold by a local
Fire/PD/EMS/Ham radio shop, with the same connector, should work.

I didn't want to drop the cash for the PTT to find that the radio mic
wasn't cut off.

It turns out my comm failure was related to my Narcos getting loose in
the rack.
