Im trying to build a repeater from 2 MCS 2000s and an ID O Matic 4 and have hit a wall. Using what info I can find the transmit radio would beacon and ID just fine..until I put the RX radio inline. Once the IDO tried to beacon it keyed up for a second then let the magic smoke out of the TX radio. Im stumped wether its a programing issue that caused a loop back into the TX radio or it was bad wiring info. I have alot of time and money invested so far and just cant wrap my brain around the issue. Any help would be a blessing. Thanks, Ben, KC3IBZ/WRFG802
