A friend of mine has a Kenwood TM-331 that he would like to interface to his 7330 controller. Turns out there is no COS output on the radio. Apparently the signal does exist inside it but I'd have to run a haywire out the radio to get at it. The RBI-1 apparently handles the COS by using the serial data stream running between it & the radio, so this would be a much cleaner way of interfacing the radio to the controller. Having full control of the radio would be nice too. I don't think these things are being made anymore so if anyone has one they'd like to part with please let me know. Thanks.
Bob NO6B P.S.: I know the 7330 doesn't support the RBI-1 yet but am confident it soon will :)
