Greetings,

I have just finished building and installing the KSB2 in K2 #5191.  The 
rig works fine on CW and SSB receive, but I am struggling to get the BFO 
tuned right for SSB xmit.

My crystals were marked "3.7".  I've set LSB to 4913.6 and USB to 
4916.4.  When I set the rig to xmit on 20 meters USB and speak into the 
Alinco EMS-42 mike, the received voice sounds correct if I tune the 
receive rig to 200 Hz higher than the indicated K2 frequency display.  
I've tried adjusting the BFO up and down without success.  The job is 
made harder because I can't seem to figure out how to adjust the BFO 
while xmitting.  I have been having to drop out of CAL FIL, xmit & test 
receive freq, go back into CAL FIL, adjust BFO, drop out of CAL FILL, 
etc.  Surely there is a simple way to do this?

Comments?
