That raises an interesting question.
 
Looking at Rob's numbers (assuming I've read the chart footnotes correctly) 
 he's done the close in numbers for the KX3 with and without the roofing  
filter.
 
But the close in numbers for K3S numbers were only done with the cw  
roofing filters.
 
Is there with/without roofing filter data available for the K3S I  missed? 
 
I realize the proof is in the performance, but still, inquiring minds and  
all that.....
 
Cheers Scott ka9p

I have a  1k filter.  Does it make much difference.  I have no clue  
really.  Would I be better served with an FM filter?  maybe  .  My main 
receiver has 2.8. 1.8. 1.0 400 and 250 or 200 filters. I  do ssb contest 
and travel to DX locations from time to time. The SSB  filters are 
essential.  For CW I honestly think that the 400 is fine  for most.  I 
dislike the sound when I really crank the skirts down on  CW but 
sometimes you must so it is nice to have it.

If you plan to  do diversity receivers you need the same filters in each 
one and they need  to be "matched" as close as possible to get the best 
results.

2.7  and 400 and and FM filter if you want fm and or AM would be fine for  
many.
