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.

AMATEURS - Your Thoughts May Be Worth
-- 6001 DICKENS AVENUE --

January 15, 1941
Frequency modulation is here - but where are
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?
