Roofing Filters

The new Elecraft site is a little vague regarding roofing filters so I am
going by memory. I have two filters in my cart KFL3A-2.8K-IR and KFL3C-400
for my third K3S. Before I hit the purchase button I want to be sure that
these are both 8 pole filters.

The KFL3A is an 8-pole filter.

The KFL3C is a 6-pole filter. In a 400 Hz bandwidth, performance will be virtually indistinguishable from the 8-pole.

Re: Roofing Filters

The old 400Hz filter was a 8 pole variety. It’s been replaced by a new and probably better 6 pole filter. As have several others.

Hello John is that not from Inrad who are a different vendor to Elecraft? Or did Elecraft supply Inrad filters at one time? I have no idea I've only just started looking.
