[Elecraft] Yet another filter question

[Phil Anderson]

Morgan,

I have the K3 RX and SUB RX too and have both the 200 and 400 Hz filters 
in each. My location is a bit noisy so I often find myself going down to 
200 Hz filters......makes a difference here. I also like to hit A>B and 
listen at 200 in my left ear plus 200 Hz in my right ear on the same 
frequency.........also use diversity on occastion..........helps bring 
up the signal out of the noise.

Phil, W0XI
