[Elecraft] K3 APF Adjustable Q

[Robert Harmon]

I have a different opinion my ham friends.
I don't mind at all an extra knob turning / button pushing to utilize APF.
You don't need the APF functionality all the time.
It is a tool to be used in the real tough cases where the signal is right down in the noise and you need that extra help to pull him out.
I'm afraid any dumbing down of the circuit to make it more automated and eliminate an extra button push, etc would also reduce its effectiveness.
If we think about what the circuit is trying to accomplish it needs to be as effective as it can be !  That tiny bit of improvement in signal to noise 
ratio it provides is critical, lets focus on optimizing it !   Like I said you don't need it all the time but I sure want it in my tool box when needed.
I am excited about the prospect of having it integrated into the K3.  There just isn't any better CW radio in my opinion.  For me its like having your
cake and eat it to with APF added.  I wanted to voice my fear of reducing its effectiveness, thats all.
