I have been referred to this address via Tim Factor, one of your agents email attached. In order to operate the radio as you mentioned, you will need a programming software. I would suggest that the 'status' of this project should be upgraded as the numbers of these radios out there are now considerable. This communication trail could be used as a learning point for obtaining needed information from Yaesu i. Usefull communication trail provided at the base of this posting.

Performing 'Serial Port Monitor' traces and dumps does not provide considerably useful information either. Is there any other model with similar CAT commands and memory structure that I might use as a starting point? I have a need for cheap cross-radio-cross-model software and have been approaching Yaesu for information. Probaly using the CAT commands for programming the FT's memory and settings seem a good solution for me, the CAT commands are documented online but there seems to be a little difference in the documented commands and the commands with the latest firmware of the FT I just ordered one of these will sell my Kenwood TS Anything I can do to help when I get it?
