[RTTY] 300hz or 500hz IF filter?

[Jay WS7I]

Joe-

You are just simply wrong. And in any case the question was about 
filters not the signal.  Been using stacked 250 Hz filters for over 30 
years on Icom, Kenwood, Yaesu radio's.  They simply work in RTTY 
contesting always have and always will.  Theory, math, which I trust 
Chen on far more than I believe you may indicate something else but 
experience tells me narrow is better for contesting,  perhaps wider for 
weak signals but if they are that weak most won't hear them at all 
during a contest which is why DXing if different from Contesting.
