[Elecraft] stereo channel output balance

[Don Wilhelm]

Gary,

I don't know what is going on, but I suggest you turn the headphones 
backwards as a test to see if the imbalance might be in the heardphones 
or in your ears.  If it switches sides with the headphones backwards, 
the problem is external to the K3.

As far as the 'high tone' is concerned, I don't have any clue about that.
