Radio Corporation of America (RCA) 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.
Most Ham radio operators know that Franklin D. Roosevelt issued an order during World War II that effectively suspended the hobby of amateur radio for the duration of the war. Many guys sold or donated equipment to the military and/or civil defense organizations out of a sense of patriotism. The Radio Corporation of America (RCA) gave a symbolic tip of the hat to them in this advertisement that I scanned from the back cover of my copy of the April 1945 QST magazine. Of course RCA pitched the ruggedness of its vacuum tubes in the process. By this edition's printing, there was a general sense that the war was nearing an end and eager Hams would not have to wait much longer to re-engage in their beloved hobby. Indeed, the next month Germany surrendered and four months after that Japan surrendered. WWII was over at long last.

See all available vintage QST articles.
