The decoder board I made was for the Yaesu FT-991.
It provides separate TX gnd outputs for different bands
as well as outputs for coax relays to switch antennas.
The difference is Yaesu has parallel BCD band data,
ICOM has serial band data coming out. But that would
be fairly easy to implement with a serial in shift register
like a CD4094 and some glue logic.
