[Elecraft] 2.7 vs 2.8

[lstavenhagen]

I also vote no on the 2.8 8 pole and instead investing in a seperate narrower
8 pole. SSB is always like trying to hold a conversation in a drunken bar
during Mardi Gras anyway (the main reason I've never used voice modes in my
amateur career), so you need something really stiff at narrower setting if
you want to block heavy QRM.

The DSP does a pretty good job but adding in the crystal filter makes it
absolutely like a brick wall. I have the 5 pole 2.7 and the 8 pole 400hz.
The difference between say 450hz with the DSP and 400 with the filter also
engaged is pretty dramatic when the sigs are really strong. Nothing outside
that filter can get through, but with just the DSP, you can start to get
artifacts from sigs that are still within the 2.7khz filter passband.
 
I'm probably going to get the 250hz 8 pole as well for CW and PSK as a
result hi hi...
