[Microwave] Polaplexer

[Dave Brown]

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.
