February 1941 QST Article

February 1941 QST

February 1941 QST  Cover - RF Cafe[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.
I have often stated that some of the most enthusiastic and capable engineers and technicians I have had the honor working with were Hams. As evidenced by this ad in the February 1941 edition of QST, heads of corporations hold the same view. None other than the president of Zenith Radio Corporation, Mr. E.J. MacDonald, Jr., thought enough of the talent residing within the amateur radio community to appeal directly to them with this full-page ad titled, "Amateurs - Your Thoughts May Be Worth Money." What makes this advertisement even more interesting is that it specifically wanted Hams with ideas about the newfangled thing called Frequency Modulation.

See all available vintage QST articles.

Zenith Radio Corporation Advertisement from February 1941 QST - RF CafeTO RADIO AMATEURS:

Frequency modulation is here - but where are the amateurs?
 
For 25 years this company, founded by amateurs, has encouraged the "hams" of the United States to bring their ideas.

As recently as the summer of 1939 we invited the entire fraternity to give us ideas on loops and we have sent reprints of the best published information on receiving loops available in the world today to hundreds of amateurs who wrote in for further information. We did not receive back very many useful ideas but after all the loop, which revolutionized radio last year, was old in the art and its sudden importance was due to rediscovery by the radio industry.
 
Now we have frequency modulation which is a really more important and more difficult field to furrow. This new art was introduced to the world in 1936 after 13 years of development in Major Armstrong's Laboratories. It has been introduced to the receiver buying public during the past year and many of its features have been publicized by the amateur magazines for many months. But, where are the amateurs?

Only a handful of frequency modulation receivers are known to us to be operating in Chicago and we have kept a very worthwhile program on the air for more than 17 hours a day and will continue to broadcast this program from now on. Other programs are being broadcast in other parts of the country and it is all high frequency experimental broadcasting.
 
In the last 3 months we have made 3 startling new discoveries about frequency modulation and the features of these inventions have been incorporated into our radio sets. But everyone of these inventions originated in our own laboratories because we haven't heard a peep out of any "ham" on the subject.

This field is new and is wide open. Where are the amateurs?

Sincerely yours,

E. F. McDonald, Jr.
