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

Re: V16 PTT
usually an unshielded wire is fine.
It is possible that, depending on your wiring, aircraft and antenna placement the cable acts as receive antenna and occasionally it may happen that it is rather good. In close proximity to an antenna you can easily get 50V of RF signal or more on a piece of cable. While the radio has input line filters for this kind of thing - if too strong it may interfere with the PTT operation - you will notice this if you press PTT and the radio keeps transmitting even though you released the PTT.
As mentioned, does not happen as a matter of course but it can if circumstances line up...
