I am looking to put a couple TK-8180's together to make a repeater as I got them cheap. Does anyone have any info on how to make this happen? These have the DB-25 connector in the rear so either the DB-25 or the mic jack I would guess there is a way to make this happen?? I have considered getting a Id-o-matic IV also so there is an id. Anyone know of the easiest way to make this all happen?
