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

[Dick Dievendorff]

And I'm embarrassed to have had to be informed that our own KRC2 will
perform a similar function. 

But what I was really looking for was the under $20 PIC project URL that
N6ML found for me.  

And it might even be easier to do with a PIC that has two serial ports, one
speaking Kenwood (or ICOM CI-V, or Elecraft K3), the other speaking KAT500.
Maybe a couple of level shifters.  

73 & Happy New Year, Joe!

Dick

Of course it will <G>.

Station Master can be used either by programming one of the antenna switch
ports to generate BCD or by using the amplifier control port as if one were
driving the KPA500/FL-7000/Quadra.
