[Elecraft] 500Hz Filter Offset Question

[Nr4c]

Well they used to be difrentisted from the 8 pole filters haven’t looked for them on new site. 

Eight pole filters have a metal can enclosing them. The five pole filters are just exposed PC boards. 

I think I have offsets set on my K3S for the 200 Hz filters.
