Drat, my e-mail archives on this computer for the list start exactly one
month after that file. Next time I'm at the parents, I'll see if I have
older archives since I was sharing a computer with them back then.

Yup I designed some filters some time back. I took a look at the email
archive and it has been corrupted by the mail archive system or some
intermediate mailer. The file was a uuencoded, gzipped tarfile. This was a
common way to send a group of files on Unix (Linux, Solaris, BSD
etc.) machines. There is no encryption at all. The mailer added a bunch of
<mail to: > remarks and damaged the file.
I don't know if I have the original work anymore. I have moved twice since
I submitted that article to the mailing list and some of the computers I
to synthesize and simulate the filters don't exist anymore. I have to see
if any of that material still exists on a CD-ROM or tape archive.
If memory serves, they were simple bandpass filters for Field Day. If you
have a specific filter in mind, it would be no problem for me to do the
filter synthesis and then simulate the filters. I have no recollection of
the specs to which these particular filters were designed to. I think it
came about after a brunch meeting with some of the local Seattle hams.
