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 |

Thanks for reading this post and enjoy those Drakes. 73, Evan, K9SQG I have that filter since almost 30 years. It is three times bigger than a normal Drake filter. It bears the label CF-2K/16. I have a one-page datasheet from Sherwood, in which they state that its bandwith @6dB is 1,800 Hz. If you give me an e-mail address, I woll send you a scan of that page. 73 Tony I0JX Rome Italy |
