[Elecraft] 500Hz 5-pole vs Inrad 500Hz 8-pole?

[Duncan Carter]

My Inrad 500 Hz filter seems to be centered perfectly.  The 250 Hz 8 
pole Elecraft badged 8 pole filter seems slightly off center but 
probably not enough to bother diversity but since I don't have the 
second receiver, I can't say for sure.

I've used the 500 Hz filter for 500  Hz Olivia without any apparent problem.
