[Elecraft] Help

If your K3 is connected to your computer for logging or rig control 
purposes, make certain that the ground of the K3 is adequately bonded to 
the chassis of the computer.  I had a similar distortion issue on my K3 
audio, and I had to go all the way down to a 10 inch length of RG-8 coax 
braid for a bonding strap to make it completely go  away.
