My first RTCM arrived and it is my intention to use one on each of my MSF 5000's. So far I haven't read of a solid way of interfacing to either CLB or CBX models. Any help would be appreciated except that I plan to place a RC-210 in front of the RTCM. We won't be voting. At best we will attempt to sync the TX and audio on three repeaters. Or not. I have no idea what the controller can do as far as external links or operating as a full repeater controller. I have a weather RX to add, a semi-duplex link, etc. I have thought of using a 2m radio (or 440; the site has 440 for control) with a RC-210 connected to it and using IT to link to the repeater. Any thoughts? I appreciate all of you! Robert
