[Elecraft] RX audio distortion with auto notch on

[Rocco Conte]

Hello Everyone,

 I have a K3 that a friend of mine let me borrow to try out. I noticed that
when I turn on the auto notch, the received audio seems to get somewhat
distorted. Voices sound sort of "muddy" and not crystal clear like they do
without the auto notch filter. This is happening on all bands and at all
different signal levels as far as I can tell.  Am I missing something here?
I have looked at the manual for settings but I am not sure what I should be
looking for.

Any advice would be greatly appreciated.

Thanks,

Rocco - WU2M
