[Elecraft] K3 sub receiver problem

[Dan Kovatch]

Greetings to the list. I seem to have a problem with the sub receiver in my
K3. I think the problem is between my ears and I am at wits end.

The sub receiver works fine on several bands (80 40 20) but does NOT seem to
be working on 10 160 15. Haven't checked the WARC bands. I have checked
antenna settings from band to band and have all set to 'main' and can notice
no difference between the setup from band to band.

Any help as to what I'm missing? I should mention that the VFO B works fine
in split mode.

Confused in frigid Ohio!
