[Elecraft] KRX3 vs APF on weak signals ??

[Ron D'Eau Claire]

And then there's diversity implemented at RF like all the older diversity
receivers used. 

In that case you cannot tell that diversity is being used, unless you have a
non-diversity receiver to compare the signal with in real time. The only
difference is that QSB is much reduced and, occasionally, the
signal-to-noise ratio is improved using diversity. 

I find the big advantage of an Audio Peaking Filter is to improve the
signal/noise ratio of a signal. Since it's a selective device, it may
occasionally reduce QRM. Reducing QRM is seldom a significant benefit in a
high-performance receiver, but can be very important in a receiver with
marginal I.F. selectivity.

I guess I'm the opposite.  I use diversity virtually all the time on
160M-20M.  Even when the rx antenna + subrx isn't necessarily making the
signal more readable, I find the stereo effect very pleasing to listen to.
