[Elecraft] K3 - getting a sub receiver - filter suggestions + dvr

[Don Wilhelm]

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.

73,
