Two-way radios


I want to be able to hook my CB upto my Autocom. It's a Cobra 148NWST. (Which of course, is not a plug and play application). I've tested my Autocom with a Radio Shack handheld (yeah, I know, cheap), and whenever I would try to transmit, I would get this incredibly loud wail from the Autocom speakers. Which now has me thinking about a repeater application. (Radio 1 connected to Autocom, which transmits to radio 2, which is hardwired to radio 3).

Anyone know how to make such a setup work?
