[Elecraft] Fwd: filters

[Barry Simpson]

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.
