[Elecraft] KRX3 vs APF on weak signals ??

[Lyle Johnson]

If it is signal to noise ratio is weak but steady, no QSB, then APF 
ought to do the trick if the CW speed is compatible with the APF 
bandwidth.  If it is a rotating signal through the ionosphere (QSB, 
fading), then diversity (including diversity */with/* APF enabled).
