[Elecraft] [KAT500] Looking for a microcontroller project that reads transceiver serial frequency messages and outputs BCD bands

[Jack Brindle]

As usual, Iain is correct. The KRC2 normally outputs standard BCD (check the KRC2 manual for details) for the band that is currently selected. The serial input selection does read Kenwood/Elecraft serial data, outputting it to the decoder terminals as well as the BCD terminals. It should work quite well in this application.

73!
