Fellow Drake Enthusiasts,

I have a 2 kc narrow SSB filter for the Drake R4C made by Sherwood
Engineering. It is somewhat uncommon because it is a 16 pole filter
and not 8 poles like the standard (optional) filters. I am unable to
find any specs on this filter, graphs of skirt shape, etc. Would be
interested in a hard copy or electronic copy of any info that is
available for this filter.

Thanks for reading this post and enjoy those Drakes.

73,

Evan, K9SQG
