Assuming it's for a K3(s), I don't think you will find the 250 Hz filter
very useful.  The response that both Elecraft and I measured shows that
the narrow filter really isn't much better.  Were I to do it again, I
would only use the 400 Hz ones.

Here's my take on filters.

I intended to send it to the reflector but realise that I sent it direct to
K9MA only.

I bought 200Hz filters for both main and sub receiver when I did a major
upgrade of my K3. I already had a 400Hz in the main receiver.

I would say from personal experience that the 200Hz filter is a very
worthwhile addition and makes a difference when the going gets tough.
