[VHFcontesting] Icom 9700 vs Icom X75 series

[Ron Klimas WZ1V]

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.
