[Heathkit] Heathkit Crystal filter information.

[Kenneth G. Gordon]

Ayear or two ago, some nice person on this list gave me (and some 
other people) some exact details on the Heathkit 3395 Khz SB/HW 
series crystal filters. They provided both Heathkit part numbers, and an 
excellent description of how they were built.

With the information given there, it was obviously quite easy to custom-
build filters of nearly any bandwidth.

Recently I have needed that information again, but absolutely cannot 
find it anywhere I would have normally stashed it.

If that person is still on this list, or if anyone else has that info, I would 
REALLY appreciate getting it again.
