Hi group(s),

I am looking for the specifications of the CAT protocol mainly for Yaesu
and Kenwood TRXs. I have the basic commands in the user's manual but I
am looking for full specs, including memories management, etc. Any
pointers or hints would be highly appreciated. TNX in advance.

P.

Get hold of a packet sniffer and trap the comms between the radio and
commercial control software such as ARCP2000.

Haven't bothered with Yaesu, but I have a Kenwood TS2000. The radio can run
up to 56.7k and looks like a modem. Uses a standard 9 pin modem cable. The
Owners Manual is available for download and carries a whole section on the
command structure. This structure has been in place since they first
started using it and they just keep adding to it. Earlier radios require a
level shifter and only run 4800bd but have the same memory and vfo commands.

Beware that even the power on and several other commands require a sequence
of commands and telemetry. There are commands that interrogate the status
of specific conditions before deciding the appropriate command or string of
commands, but simpler things like reading vfos and mode are simple and
included in many third party programs.

I am currently using ARCP-2000, LOG-eqf, RIG-eqf (for dos), MCP-2000, and a
very interesting Excel spreadsheet by K9DCI that allows management of
extreme frequency lists.
