Joe,
The filter match or not match question does revolve around your decision
about diversity mode.
How many times are you in QSO when QSB becomes a problem? The answer to
that question is the real decision point for a casual operator. If your
answer is that QSB is never or seldom a problem, then you do not need
matched filters in the SubRX.
OTOH, if your answer is that "sometimes" or "frequently" you experience
QSB on a signal that you deem important enough to complete the contact,
then you need to consider filters that match those in the main K3.

Greeting all.
Between my birthday and Christmas my wife has OK'd the purchase of the
sub-receiver for my K3 (#6623).
I have read the recommendations by Wayne on the order site and originally
thought I would just duplicate the filters in the
main receiver (2.7, 400, 200) as I do mostly CW and Data but I do enjoy casual
SSB also.
I note form Frank Cady's book that the primary reason for having the filters
the same is diversity reception and that do not need to be the same.
Right now finances only allow 2 additional filters.
So I have been giving it some thought - would it be reasonable to put say a 1,0
filter and a 2.1 filter in the sub or perhaps match the 400 and add either a
1.0 or 2.1?
I realize that my operating style influences this - I am not a contester -
just enjoy casual operating and some DX.
The other issue would be adding the DVR - I was thinking of getting it just
because it looks like it is easiest to install it at the time of the
subreceiver addition though I am not sure how much I would use it and if I
don't get it - I can probably add one more filter.
"Found" Elecraft last Spring - now have K3 and KX3 and love them and this
reflector.
Thanks es 73
