When you pull the 1KHZ filter out and replace it with the Inrad 600HZ filter, 
are you replacing the 1.8KHZ filter with the 1KHZ filter like some are?  
That would make sense for a CW op and since the 1.8 is useless for SSB 
anyway, I would do it.  But, why should you have to purposely defeat the TenTec idea 
of having the roofing filter kick in at 75% of the DSP?

Why did TenTec pick 75% and what are the disadvantages of tricking the radio 
by putting a narrower filter in the slot?
