[Elecraft] Fwd: no8v: APF Primer? - 2020-08-25

[Bill Frantz]

APF is not a cure all. It is an alternative to narrowing the 
bandwidth to the minimum to try to improve the signal to noise 
ratio. If there are strong signals near the one you are trying 
to receive, from a crowded band or DQRM, then it isn't going to 
help. If the band is reasonably quiet around the signal, it can 
make reception possible.
