You insist on making this an either/or kind of choice, and it simply
is not. APF does not make a result in your brain, it simply listens
to slower CW with a very narrow bandwidth. It seems to have times when
it will pull something out of noise, and other times not, by use of
the narrowness.

To get a good taste of diversity for weak signal cw reception, plug a pair
of stereo headphones
Thanks for the explanations and your patience gentlemen.
I've got it now.

Hi Chuck,
Diversity reception may not work for everybody. My brain can't handle it.
Having a near identical sound in both ears with one side fading in and out
doesn't seem to make it easier for me to copy. I prefer to just switch
between two antennas and listen to the one that sounds best. To do

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
1300 miles. (lots of info on my website)

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,
Hello folks.
I operate cw 98% of the time.
After 'rag chewing' for several years I'm becoming more interested in
DX'ing. Also I'm eager to try my luck on 160 meters despite my QTH and
antenna restrictions.
I've been considering purchasing the KRX3 (second receiver) for a year or
more.
However

Chuck, the second receiver does more than just offer diversity. A lot of CW

Your question reads like, Do I have enough rocks in this bucket, or
do I have more hammers in this bucket?
The APF does not do what diversity does for you. APF is a monaural
concept. Diversity allows you to spread the noise while signals
remain discreet. This is something which your ears
Thanks for the responses but I'm at a loss as to why the question is
confusing. I'm trying to determine the most efficient method to hear
weak/fading cw signals.
I have read on here many times where folks brag on the 2nd receivers'
ability to overcome fading band conditions via diversity receive
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).
