I believe DTMF tones come out of the RBI-1 to control the kenwood radios. I don't remember for sure.

Hi Guys, >Woohoo, the Doug Hall "Rosetta Stone"! Thanks, Skip. We need to go back a little deeper in history... I think the format you have is the data going from the controller to the RBI-1. Doug H based it on the dominant format at the time, which was the format used by ACC to drive their "frequency control" shift register boards (designed for thumbwheel HTs). Doug made his input format available to repeater controller manufacturers in his "generic" document so we all could make our controllers RBI-1-compatible. We added that feature to our 7K in V2.01. It's not that big a secret. The output format of the RBI-1, on the other rhand, is the format Kenwood used to control a group of radios in the trunk from a handset (was it called the RC-10? RC-20?) in the driver's compartment. His box was a protocol converter that took the 48- or 56-bit stream from the controller and make Kenwood-speak out of it. Wasn't trivial at the time. 73, Bob, WA9FBO S-COM, LLC Wondering what's for Dinner Tonight? Get new twists on family favorites at AOL Food.
