[Elecraft] KRC2 rs232 to cpu not working

[Don Wilhelm]

Gordon,

Have you checked the internal jumpers to be sure it is properly plugged 
for use with the K3.
Download the newest KRC2 manual if the one you have does not include use 
with the K3 - see page 23.
You have the choice of using the AUXBUS (if you only want the band data).
If you are using the serial port, the baud rate on the K3 and the PC 
application must be limited to 19,200 or below.
