Thanks for the replies. I have gone thru the GTR200 Headset Tests. That is where I found out the right speakers were not working. My headset is set to stero, verified by plugging them into my pc and listening to music. Any other ideas? Is there a way to hook up to the pins coming out ot the GTR200 and check activity? If there is no activity there, then it is the radio. If there is, then it is the wiring.
