From tractorb at ihug.co.nz Tue Aug 30 23:22:56 2016 From: tractorb at ihug.co.nz (Dave Brown) Date: Wed, 31 Aug 2016 15:22:56 +1200 Subject: [Microwave] Polaplexer Message-ID: <47B6B0D847114009A82A7C9084DCCB52@athlon3200> According to an article by David Laag on the San Bernadino Microwave Society website, the originator of the polaplexer was evidently Donovan "Tommy" Thompson, W6IFE, who was a central figure in Southern California microwave activity from 1947 through 1969. His idea, the use of Polarity-Duplexing (The Pola-plexer), was the basis of nearly all early amateur microwave work with klystrons. In his article, Laag notes that "In November 1955, Bill W6VIX published the first of three articles covering the design and construction of a "Pola-plexer" for 3,300 Mhz." I can't find this series of articles in QST so where were they published? There IS a single article by W6VIX in QST for December 1957 that deals with the polaplexer but that's the only W6VIX reference that appears in the cumulative index. Any hints as to where I can track down the three articles mentioned by Laag would be appreciated. 73 Dave, ZL3FJ From geraldj at netins.net Wed Aug 31 00:01:50 2016 From: geraldj at netins.net (Dr. Gerald N.

There might be more by putting the hyphen in Pola-plexor. 73, Jerry, K0CQ On 8/30/2016 10:22 PM, Dave Brown wrote: > According to an article by David Laag on the San Bernadino Microwave > Society website, the originator of the polaplexer was evidently Donovan > "Tommy" Thompson, W6IFE, who was a central figure in Southern California > microwave activity from 1947 through 1969. > His idea, the use of Polarity-Duplexing (The Pola-plexer), was the basis > of nearly all early amateur microwave work with klystrons. > > In his article, Laag notes that "In November 1955, Bill W6VIX published > the first of three articles covering the design and construction of a > "Pola-plexer" for 3,300 Mhz." > > I can't find this series of articles in QST so where were they > published?
