This was my first time using the new QST archive system, so I was
learning as I went.
Once you register for the ARRL web site and sign in, go here:http://www.arrl.org/arrl-periodicals-archive-search
and then enter the search information. I couldn't figure out how to
specify a range of years, so had to search one year at a time. Searching
for "transmatch" seemed to give better results than "tuner". You can then
pull up each article of interest as a PDF file.
