[Elecraft] KRC2 rs232 to cpu not working

[Michael Eberle]

A lot of people seem to be having issues with it.  I remember mine being 
a pain to get set up (mostly operator error) but it works fine now.  I 
use it to switch amp keying from the KPA500 to the 2M amp when the 2M 
band is selected on the K3.  When 2M is selected, the KRC2 energizes a 
relay that switches the key out of the K3 to the 2M amp.  You do have to 
change the switch on the side from OP to DL before it will communicate 
with the computer.  Also I believe you have to set the baud rate on the 
KRC2 with jumpers.
