Actually, changing filters in the second rx is harder. To change the
filter in rx 1, you can just lift rx 2 out of the way. But to change the
filter in rx 2, you must remove it and take the board out of the shield
box to get at the screw that holds the filter!

Presently I have 6, 2.8, 0.4 and 0.25 kHz - all being 8 pole.
One more issue Len. In your example above, you should only use diversity in
the WIDTH range where identical filters will be in use. You would

I am getting only the standard 2.7 for my second
receiver. You can use the DSP to narrow the
response to whatever you need even though you
Hi Orin,
Copying this to the list since others may have a similar situation.

Yes. All of the 8 pole filters have a zero offset.
Its the 5 pole filters that have varying offsets.

Now I'm curious.
When I installed my 400 Hz filter, it had no
offset info on it. Is this normal?

I have a somewhat similar philosophy. I ordered the second receiver
without additional filters. When/if Elecraft introduces their
variable-bandwidth CW filter I will order one to replace the 500 Hz
filter I now have in the main receiver, and put the 500 Hz filter in the
second receiver.
