I am thinking about trying to use an Elecraft KRC2 Band Decoder to control
the band switching on a Ameritron ALS-1300 (same remote control as the
ALS-500 and ALS-600).  The rig will be a Kenwood TS-480.

The KRC2 is capable of reading band data from the TS-480 and controlling
relays, so this looks like a good fit.

I also want to maintain full communication from a PC to the radio, so the
KRC2 must just listen to the RS-232 line and not interfere.  I think that
this is possible from reading the manual.

The Ameritron ARI-500 is not suitable as it continues to send status
requests to the radio and does not listen (half duplex) while it is sending,
causing strange band switching behavior on the amp.

Has anyone controlled an Ameritron solid state amp with a KRC2?
