[SECC] Re AA4LR comment on a claim jumper

[Jerry Flanders]

I primarily run, and only (currently) work RTTY contests. With my 
756PRO I have steep-sided filters, and routinely use 250 Hz, which is 
all I need to hear stns calling me BUT I worry about my CQ being 
heard by S&P guys using conventional filters. If they hear QRM near 
my call freq then maybe they can't copy me.

So if I keep my filters narrow to help me receive weak stns then I 
don't hear nearby QRM when it starts up.  Maybe I waste time calling 
when average stns can't copy me.

There is probably an optimum Rx BW for calling stns. Any guesses?
