Found the problem ;-) - Senior moment operator error :-(  I found that I had 
inadvertently switched the 6m relays to enable transceive rather than provide a 
separate receive line with the dedicated external preamp.  The bottom line is that 
the birdies were appearing because there was no antenna connected.  Once things 
were switched back to normal, everything worked FB again ;-)

Getting closer to successfully incorporating the K3 into the station here - HI! 
Best wishes to all for a joyous holiday season!  VY 73, Lance
