[1000mp] Sub receiver filter question

I swapped the stock 500 for an Inrad 250.  I use the sub Rx for chasing 
mults on the same band I'm transmitting on in contests.  Because I'm not 
very good at decoding 2 different sets of cw signals, one in one ear and 
one in the other, I find the 250 helps a lot to  reduce the QRM and am 
very pleased that I did it.

Those who suggest that the 250 is too narrow for use in split pileups 
are probably right but my main interest is contesting.  Chacun a son 
escargot.
