Hi Barry,

 From your description, it sounds like you're hearing VFO tuning  
noise.  The original complaints mentioned 6m, 10m, and 60m, but not  
12m so I don't know if it's the same problem or not.

Elecraft published a mod. note describing a combination hardware/ 
firmware fix for this at

http://www.elecraft.com/K3/mods/K3_vfo_noise_mod_Rev_C.pdf

In my case, I had the noise at the bottom end of 10m.  Initially, the  
hardware/firmware mod didn't seem to help much, but after going back  
in and tightening up all the screws and rearranging some TMP cables,  
the noise went away completely.
