[Elecraft] (K3) APF and selected bandwidth

[Brian Hunt]

On the other hand, when used in conjunction with NR a wider DSP BW is desirable since NR works on uncorrelated noise. Try:
BW= 700-1000 Hz,
NR= ~ 5-3
APF= ON
Great for pulling out weak signals on an uncrowded band. The NR settings of 5 and above mix processed and non-processed data so the APF has something to work on.  My theory, anyway.
