[Elecraft] Manual notch In K3

[Johnny Siu]

Hello Group,

I attempted to manual notch a strong carrier adjacent to a weak station.  
Although I was able to notch out the strong carrier (from the audio), there was 
no reduction in S meter level caused by that strong carrier.  In other words, 
the weak station did not pop out from the noise because the stronger 
carrier de-sensed the K3 AGC.

Please advise whether my observation is correct.

TNX,
