[Elecraft] Slight tx noise?

[Joe Harris]

Hello,

I have had a K3/100 for a few months and I'm loving it.

My question concerns a barely audible, very high-pitched whine coming from
the rig on transmit. Actually, it still happens when I'm in TX test mode. I
don't believe it is the fans. I searched the reflector archives and didn't
see anyone else mentioning it. Is this the norm, or am I blessed with a
unique feature?
