WSJT-X/HRDTransceiver.cpp
Bill Somerville 3ddf0d64d3 Igonored CAT polls of RX frequency from Commander when transmitting as 
they are unreliable on Icom radios.

Simplified diagnostic output for HRD CAT interface and DX Labs Suite
Commander CAT interface.

Removed duplicate diagnostic message from configuration CAT control.
