[Elecraft] K3 on 10M CW bad

[Don Minkoff]

During the California QSO Party this past weekend as W6COW, I was using 
my K3 as part of a multi-multi.

10 meters was open both days and on Sunday I received a complaint about 
my CW tone.  I just now verified a problem only on 10M.  It sounds like 
two signals (two tones) and creates a buzzing sound. I might also had 
that I was using a 10M band pass filter.

Before I have to box it up, anyone have an idea? Never had any problems 
with this radio since new, way back in 2010.

Thanks,

Don, NK6A
