You probably overlooked the simple thing. The PTT line is DC and once the SCR
fires it will latch. If you had AC then the voltage goes to zero and the SCR
unlatches.

I got a Solid State Relay and the com port will trigger it. (same thing I use
to control my Christmas lights from my computer). However for some reason the
PTT won’t drop when the SSR shuts off. I know there is some voltage bleed on
them but I can’t figure out why it would stay grounded afterwards. Any
suggestions on that one?
