[Elecraft] Another one of those filter questions

[Mike K2MK]

Hi Alan,

The information is in the manual but you sometimes have to search for these
things.

On page 46, the crystal filter setup page, it states that you should enter a
gain of 1-2 db for the 400 Hz filter. I have a 400 Hz filter and I have
entered 2 db.

I searched the PDF version of the K3 manual for offset and found on page 79
that it states that all 8 pole filters have zero offset. A note to this
effect should have probably been added to page 46.

I purchased a 400Hz 8 pole (Inrad) filter and installed it in my K3
yesterday.
There were no markings on the box and some obscure numbers on a small label
on the side of the filter case, but there was no offset figure.
The Cady book mentions that for 8 pole filters an offset is unnecessary, so
I presume this is correct?
It also mentions adding a small gain figure of 1 or 2, what do others
normally do for a CW filter?
