Since the internet is lacking information on connecting a pair of Maxon SM-2150/4450 or GE Monogram mobile radios to make a repeater I have worked out the connections that need to be made to interface radios to a CES RM-10 RepeaterMaker.
The connection tchart should be pretty generic for most brands of controllers, you just have to work out what needs to go where on your specific controller.
