[Elecraft] K3 NB

[Don Wilhelm]

Mike,

Good work to have discovered where the problem lies.  You might want to 
obtain a new KNB3 board and simply replace the one in the mainRX.

Yes, you can swap the KNB3 between the main and the sub, so if you want ---

Look in the K3 assembly manual as well as the KRX3 manual to see where 
they are plugged in - as well as how to remove the KRX3 to get at the 
KNB3 board on the main board.

The process is:
Remove the top cover
Remove the KRX3 assembly
Take the top cover off the KRX3 and remove the KNB3
Remove the KNB3 from the main and put it in the KRX3 (the top cover can 
now go on)
Put the KNB3 that was from the sub into the main
Put the KRX3 in place being careful that both the SubIN and SubOUT 
boards are in place.
Reconnect the cables to the KRX3
Put the top cover on.

Job done.

73,
Don W3FPR
