icom 730 help with PTT for transverter

Post by mastercare »

Hi all , i may be being thick here but i need to control my transverter from my old but faithful icom 730...
ive looked at the acccessory socket and trying to find a pin that goes to ground on tx...
no luck is there another way doing it.. the transeverter has a simple phono socket on back when grounded goes into tx mode..
cheers in advance

If you're just looking for a switched ground via the PTT can't you go route1 and do a continuity test putting one side to ground and then probing for a match when keying?
