The above is trivial IMO. I'm talking about full radio control. >Now if one wants freq control then the various manufactures use different >standards requiring a custom interface for each.

All that is needed is some memory to handle lookup tables for the various protocols & extra program code, and maybe even a DTMF encoder for controlling radios like the Kenwood TM-G707. Speed should not be an issue. Bob NO6B
