Picked up a Motorola GR300 Repeater with a GM300 for recieve radio, a M120 two channel 40 watt for the transmit radio and the 'RICK' basic controller, an ID-O-MATIC cw id interfaced into the RICK. More info on the id-o-matic here www.hamgadgets.com/product_info.php?products_id=64 . A Cell Wave Duplexer. Reprogrammed the radios for my repeater pair. The repeater is up and running now.

Interfacing the ID-O-MATIC cw id'er to the Motorola RICK ACC connector is very simple.
