Post the information printed on the filters, and maybe someone just
happens to know.

Hi, Michael and others,

Ron W6ZI was kind enough to solve this mystery and respond with the
following:

"The 10.9MHz C-F Networks filters were used to replace the standard filter
in
the Swan 250. The 250 had a 10.7MHz I.F. so a bit of retuning was required.
The stock 250 filter was a 4 pole, 3KHz (more or less) B.W. while the C-F

was an 2.8KHz, 8 pole which provided a very noticable improvement. Hope this

helps."



Thanks, Ron.

Regards,
