All the PTT switch does is ground a logic gate, so unshielded 22-24 Tefzel is more than adequate. I personally wouldn't use a connector, just run from the switches to the connectors on the back of the Becker and the V7 (less to go wrong).

Many people have posted that 22-24 tefzel is the stuff to use.

Should the wire be shielded?

Is there a "best" type of quick disconnect connector to use for this small guage wire. I was going to use a JST connector, although I have no idea how much current is running through the PTT or the V7 climb circuit...
