[RTTY] Best filter...its all in the shape factor.

[KH6DV at cs.com]

I had 500Hz filters in all my Kenwood radios, they had terrible shape 
factors and didnt work well on CW or RTTY. I replaced them with INRAD 400Hz 
filters that had great shape factors and it was a night and day difference on 
both CW and RTTY. I find that a 250Hz filter is too narrow for S&P to suit my 
taste.

Just my 2.5 cents worth.
