That wasn't what I was saying.  Yes, sure the 1.8 Khz roofing filter is useful in 
contests or just 75M at night :-)

Someone said they were going to stick the 1.8 Khz filter it in the 2.4 Khz slot (I don't 
think it was you, but might be wrong), and there was a follow-on comment that that 
might not work because of transmit signal routing.  

I was thinking "6Khz slot" when I made the comment above (brain on vacation), but 
generally my statement really was to say that it doesn't make sense to use a 
narrower roofing filter than DSP bandwidth.

I still sense confusion among some (you not included) about roofing vs. IF filtering in 
the flow of the discussion,  however.   And think we're getting bamfoozled to some 
extent by the option count :-)
