[Elecraft] Receiver Performance Numbers with SSB filter

[Dave White]

I was wondering if anyone has evaluated the K2 receiver performance numbers 
with the KSB2 as the principle IF filter instead of the onboard filter 
adjusted to 500Hz bandwidth?  I expect the 5Khz BDR and IMD DR3 might suffer 
somewhat, but has anyone actually played with this?

IMD DR3 seems to be a "hot number" that lots of folks are focusing on 
lately, but I'm trying to decide how relevant this excitement is in 
"real-world" SSB work.

Regards
