Delco Radio Advertisement
April 1945 QST Article

April 1945 QST
RF Cafe - April 1945 QST Cover[Table of Contents]These articles are scanned and OCRed from old editions of the ARRL's QST magazine. Here is a list of the QST articles I have already posted. As time permits, I will be glad to scan articles for you. All copyrights (if any) are hereby acknowledged.
Here is an advertisement for Delco radios that I scanned from page 91 of my copy of the April 1945 QST magazine. "'Control the Air' has a new meaning today," that's the tag line referring to the need to dominate wireless communications in the effort to conduct effective warfare. Radio certainly wasn't a new science in 1945, but secure communications - including spread spectrum techniques - was a vital technique both for transmitting and receiving messages and for jamming the communication of our enemies. Delco, as was common in the World War II era, encouraged citizens to buy War Bonds.

See all available vintage QST articles.
