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. 73, Wayne N6KR > On Jun 18, 2019, at 8:21 AM, [hidden email] wrote: > > The new Elecraft site is a little vague regarding roofing filters so I am > going by memory.

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 It’s been replaced by a new and probably better 6 pole filter.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.
