Diversity Revisited

Michael Raskin
I asked this same question back in December and received many response.  I
then summarized the responses and posted that summary on this reflector.
Now that it's seven months later, I was wondering if anyone wants to share
any additional experiences.  I use diversity reception with two antennas,
one for the main and the other for the sub-receiver, on the low bands
(40-160).  For receive only, I have a K9AY loop and, soon, the DX
Engineering 4-square receive antenna on a separate lot about 100' away.
Most of the DX activity on the low bands is on CW, except for 80, where
there is a considerable amount of SSB activity.  For diversity reception,
the manual says that the best results are obtained when the filters in the
main and sub are the same bandwidth and matched.  I am using a pair of 500
Hz for CW diversity but wondering what others are using for SSB diversity.
Are the pair of 1.8 SSB filters worth it over the stock 2.7 filters in the
main and sub?  Also, are the 200 or 250 filter too sharp for CW diversity on
160 (my primary low band area of interest)?  What are others using for CW
diversity receive?  Anyone using diversity for other than the low bands?
How about BC diversity using 2 general receive modules?
