<----While I'm not intimately familiar with the protocols of the older Kenwoods, Kenwood has historically used 9600 baud for its mobile radios' serial data. I know for a fact all the newer ones do (TM-V7, g707, V708, TM-271A). This is the easy part..... The problem comes from Kenwood NOT having any sort of "standard" in the protocol used. When we coded up the control code for these radios for our controllers, we used a port sniffer to figure out the protocol used for the various (and totally undocumented!) commands. While Bob brings up an interesting point about SPI, I really don't think this is the case. Then again, I've been wrong before :-) However it should be easy enough to figure out with a working RBI-1 and a 'scope.
