In the installation manual it shows hooking up the ptt switch with a shielded cable, is this necessary or can it be just hooked up with a single ground wire from a ray Allen stick control?
Thx, Steve

A simple unshielded grounded wire works fine.
Remember to connect to both PTT1 and PTT2 if you have a single PTT and want either mic to be live on transmist.
