A similar article appeared in the December, 1979 issue of QST: http://p1k.arrl.org/pubs_archive/73673
Rather than passively coupling the transmitter to the dummy load, he used an RF transformer on a ferrite core. It also measures SWR with the usual FWD and REF displays, rather than an absolute value null when minimum system SWR is reached.

If you can secure permission for the ARRL, I'll send you a copy. Paul, W9AC Thanks Paul....I do not think it is on line, but I do have the QST. Apparently, QST does not have articles on line from recent issues. I am very keen on building this device. I think it is a handy gadget. Thanks Paul for giving me the information. Thanks to all who sent me other article locations as well to similar device. Top-notch people on this reflector.
