article is from the August 1958 edition of Radio and TV News
magazine. It describes shunt-fed modulation (often refered to as
modified-Heising). The author, then W3FEP, Richard Genaille also
details on how he used the shunt-fed system with an ART-13 modulation
transformer in his 500-watt AM transmitter. This is a great read from
the past and the information is just as valuable today. Thanks for
Rodger, WQ9E for scanning the article and John, K5PRO for the PDF.
