[Elecraft] K3 Auto Notch Distortion

[Toby Pennington]

Distortion of the Auto Notch does exist,  how bad depends on the strength of the signal you are listening to. 

This has a lot to do with whether the notch is inside or outside the 
AGC circuit.  I THINK on the K3 the auto notch is outside the AGC,  and on the upconversion rigs like a 7800 Icom,  it is on the inside of the AGC circuit.  This makes for the best quality sounding auto notch.  

I don't think this can be changed in the K3   The other thing about having the notch set up like it is in the K3 is that a strong notched signal can seriously desense a signal you are trying to listen to.  This is not good,   so I usually try to use the manual notch to prevent problems.
