Welcome to W3NQN's Home on the Web. Ed Wetherhold's CW Audio Filter Kit. Ed - W3NQN - designed his famous passive cw audio filter in the 1980's. His articles in QST magazine described how to build this filter using surplus parts. Then he began to supply the hard to find surplus toroidal coils in the filter. He finally put together a complete kit, with all the parts, coils, case, and directions to build the filter. The filter is still available from Ed himself today! Buy your own kit today.

It is definitely easy on the ears. The filter was build in a couple of hours, most time was needed for the glue to dry. I tried several different, both current and vintage, "active" type audio filters and fou...

About Ed Wetherhold - W3NQN. Designer of the Famous W3NQN Filters. I retired in 1992, and since then have been enjoying retirement by producing my passive CW filter kit, and building LC filters for amateur radio contesters using Array Solutions as my distributor. I used to play competitive senior tennis in the Washington-Baltimore-Annapolis area, but after reaching 82 years, I find it more useful to build filters for sale. W3NQNCOM Made in the USA 2010.
