It depends on what you want to use the 2nd receiver for. I am primarily 
interested in using it for finding the correct spot in a CW pileup to 
call a DX station, so I will mostly be using a relatively wide 
bandwidth. Therefore I chose to use a single 2.8 kHz filter in the sub 
(I have 400 Hz, 1 kHz and 2.8 kHz in the main rx).

I am also interested in experimenting with diversity reception. If I 
were to do this seriously I might want another 400 Hz to match the one 
in the main. Also, for diversity reception it's best for the filters to 
have the same offsets (which is why I swapped the 2.7 in sub receiver 
for a 2.8 to match the one in my main rx).
