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.
