[Elecraft] Filter Selection

[K4IA at aol.com]

Wondering if a consensus was developing about  the choice of roofing filters. 
 Seems like there a too many to choose from.  Lacking detailed plots for each 
one, I can't believe there is that much  difference between say a 500hz 5 
pole and a 400hz 8 pole or a 200 hz 5 pole vs a  250 hz 8 pole.  Sure the 5 poles 
will have wider skirts but will you be  able to hear the difference?  

I would think the 500hz 5 pole would  be fine for CW and the stock 2.7 would 
be fine for SSB.  Maybe add the 1.8  if you do a lot of SSB contesting.    I 
have an Orion so I am  used to roofing filters - they are a dramatic 
improvement over the wide open  front ends of the YaeComWoods but you don't need to go 
crazy with multiple  filters since the DSP does all the work and the roofing 
filters only make a  difference in really crowded conditions. 

Comments?
