Mike,

I've got a few Heil things here, and the PTT has always been 1/4 inch 
mono.   I don't see why you couldn't use a stereo plug if that is what 
you have.    You just need to  wire it so that the tip and shell are 
grounded when the switch is activated.    The "ring" or center of the 3 
connections  on the plug would be left unconnected.   You could probably 
tie it in with the shell or ground, but why bother?

As I already have a foot switch, I'll change out the RCA connection for a plug to match the CC1 PTT which I could probably pick up along with the mic for about 7 bucks. I'm looking to spend about 150CAN to put it on the air and the Heil line of products aren't cheap.
