[Elecraft] [K3] The Way We Rank Receivers (long)

[Bill Frantz]

I assume that Don means a 30Hz wide peak below.

While I have found APF to be good for digging out weak CW 
signals near the noise level, I have found a 50-100Hz bandwidth 
works better when there are nearby strong signals. (I have the 
250Hz crystal filter.) The K3 won't let me narrow the DSP filter 
that much with APF on, probably for good reason. Am I missing a 
way to use APF in these tight spaced conditions?
