When the concept of radio refrigerators
was presented in a 1933 edition of Radio-News magazine, it was not quite what has become
reality today. At the time, the Radio Electrical Exposition had recently been held
in Madison Square Garden and the world was just getting used to the miracle of radio
waves - and refrigerators for that matter. Radio-refrigerators never did make their
way into the consumer market. Fast-forward 80 years and now we're seeing the advent
of radio-refrigerators re-emerge, only in a completely different format. This time,
rather than playing shows from local commercial broadcast stations, these appliances
are communicating with Wi-Fi routers to allow owners to check on status and contents
from remote locations. In other news, the editors report on a scheme to use a remote-controlled
airplane, signaled by a Tesla spark gap transmitter, to drop bombs inside tornados
in order to break up and stop their destructive presence
(that drawing of a low-wing, single-engine monoplane that looks a lot like a Piper
Cherokee, was way ahead of its time). There is also a photo of Major Armstrong's
original lab notebook sketch of his idea for a regenerative receiver circuit. It
is usually very worthwhile to have a look back in time to see what was developing
and being foreseen.
The Radio Month in Review
No, gentle reader, this combination radio refrigerator was not
at the 1933 Radio Show. It may be there next year.
Radio is now such a vast and diversified art it has become necessary to make
a general survey of important monthly developments throughout the field. Radio-Craft
analyzes these developments, and presents here a review of those items which are
of interest to all.
New York Radio Show
The Radio Electrical Exposition in Madison Square Garden came to an auspicious
ending on Saturday, September 30th, after having run for ten days, Sunday included.
The show was a great success, it is claimed by the exhibitors, because more than
200,000 passed through its gates. According to the management, the show drew over
$1,500,000 in business for the exhibitors, and they are so heartened that they will
run another show in 1934, to be held September 19th to 29th.
Loitering around the show, the editor tripped over dozens of refrigerators in
his search for radio sets. It was a grand show for refrigerators and, once in a
while, he could discern in the offing some radio sets. The only thing that was missing
was a combination refrigerator and radio. The whole ground floor was at least 80%
refrigerators, with 20% radio sets thrown in for good measure. This should not be
considered a harsh criticism of the show, because it was not a Radio Show primarily,
for the pure, unadulterated radio shows of former years had blown up; and the depression
made it necessary to combine radio and electricity, which the exposition did successfully.
As far as we could find out, not a radio parts manufacturer was represented.

The new Broadcast Noise Robot creates anything from the roar
of 10,000 baseball fans to the crash of two automobiles.
The new Radio Typewriter now ready for the market. News and static
are equally enjoyed by it.
Tesla Tames Tornadoes
And now comes the veteran 79-year-old scientist, Nikola Tesla, the world's greatest
living inventor, who says that he has found means to tame the tornado, which annually
takes toll of thousands of human lives, not to speak of the millions of dollars
of property damage.
Paying a visit to Hugo Gernsback, editor of this publication, the other day,
Dr. Tesla disclosed his plan which, by the way, is published with a great many Illustrations
along with his original article, in the December issue of Every-Day Science and
Mechanics magazine.
Tall, gaunt, and sparse, the ascetic great inventor retains a keen interest in
applied science. His recommendation, in a few words. is to use radio-controlled
robot airplanes, which can be controlled from the ground. The airplane is sent up
and directed straight toward the funnel of the tornado as soon as one is reported.
Should a tornado start at sea, the same thing can be accomplished by Government
patrol ships, which will dispatch radio-controlled robot airplanes tornadoward.
The trick, according to Dr. Tesla, is to drop a huge charge of explosives right
into the mouth of the tornado funnel. This is to be accomplished by distant watchers,
who spot the airplane when it is directly above the funnel and release by radio
impulse an explosive charge which, dropping into the funnel, destroys the whirling
vacuum of the tornado and stops its progress before further damage can be done .
Armstrong Regenerated
Every radio fan worth his salt knows what regeneration means. It means
additional power, more sensitivity, to radio sets. Short-wave fans, particularly,
cannot do without regeneration. But who is the inventor of regeneration?
Last month, the now totally bald, but youngish looking Edwin H. Armstrong walked
in on the editor of this publication. For the first time in 12 years he smiled.
For the first time in a dozen years he consented to talk about a sacred and taboo
subject - Regeneration. Reason: there has been a 12-year battle about it between
Dr. Lee deForest, the inventor of the 3-element vacuum tube and Major Edwin H. Armstrong.
Recently, the U. S. Court of Appeals for the Second Circuit handed down its verdict,
making Armstrong* the sole and undisputed inventor of regeneration.
Armstrong showed that he first invented regeneration in the year 1913, and he
conclusively seems to prove now, that he and not deForest is the real inventor.
Of course, the Supreme Court has not as yet rendered its verdict, and on the other
hand, the controversy may never go to the Supreme Court.
The radio fraternity will now arise en masse and shout congratulations.
*The decision was rendered in favor of the Radio Engineering Laboratories, Inc.
against the Radio Corp. of America. A. T. & T. Co., and de Forest Radio Co.
Ed Wynn Chain a Dud
With a great amount of fanfare and noise throughout the daily press, and colorful
noises at the headquarters of the newly-born Amalgamated Broadcasting System, the
newest national broadcasting chain made its debut on September 25th. It is Ed Wynn's
long-heralded "third chain." Most of the noise was made on the 11th floor of the
vast A.B.S. quarters at Madison Ave. and 52nd St., New York. We say most of the
noise and hullabaloo was in the broadcasting offices; because very little of the
noise percolated into the ears of the chain's prospective listeners. We expect a
real broadcasting chain to have millions of listeners, into whose ears the noise,
or sound, will finally settle.
Alas and alack, the new A.B.S. chain is not destined to do so. The reason is
that the chain is a chain in name only, and, from what we can see, it will never
amount to much for some very simple and elementary reasons.
All of the stations, with the exception of two, are in trade parlance so-called
"graveyard" stations; that is, they are so far down in the broadcasting spectrum,
that broadcast listeners are unlikely to tune in any of them, even though Ed Wynn
himself were to broadcast all day long - which he probably won't. Not only are all
of the stations except two - WHDH, Boston and WLBZ Bangor - down in the graveyard,
but they have no power either. All of them put together don't come anywhere near
having half of the power of one such station as WABC, WJZ, WEAF or WLW. Most of
these stations cannot be heard for more than 25 miles, if so far; and in congested
districts like New York, Philadelphia and Washington, these "repeaters" on out of
town station wavelengths can be heard only a few blocks. Heterodyning, they have
birdy whistles, or a program of unintelligible hash.
The idea of a third chain is O.K. if the promoters had the stations; unfortunately,
the chain has no stations to amount to anything and, when they talk of a "national
outlet," as their high-pressure advertising department no doubt will, it will be
found that the outlet is not functioning. The only people who will listen to the
emissions will be the advertisers; and, in our opinion, as former owners of a fairly
decent broadcast station, the advertisers will not get results.
With no exception the A.B.S. goes to the identical cities now adequately served
by National Broadcasting Co. and Columbia, where both veteran chains control good
station outlets. A.B.S. covers no new territory, no new towns, performs no discernible
service.
The new chain does not use American Telephone and Telegraph Co.'s 'phone lines
to link together its out of town radio stations; instead it uses Western Union wire
lines. Broadcasters have tried this cheaper method time and again, but have found
out that they are noisy and can't be properly balanced. Broadcast engineers in the
know never use them except in dire emergency.
If the third chain is simply a scheme to sell stock, it may succeed in this,
but the poor investors will be stuck, as usual.
We have all sorts of respect for Mr. Ed Wynn as a comedian but, as a broadcaster,
we believe he has pulled a serious boner, and has been deluded by promoters.
Stations of the Amalgamated Chain
Marconi in the United States
Marconi returned to the United States, last month, on a special invitation to
the Century of Progress in (Chicago. Senatore, now the Marchese (Marquis) Guglielmo
Marconi and the Marchesa Marconi arrived at New York on the Italian liner Conte
di Savoia on September 28th.
Piloted by David Sarnoff, head of the Radio Corporation of America, to the new
Radio City, just opened, Marconi had to run the gauntlet of some twenty-odd radio
scribes who corralled him in one of the rooms in Radio City and lambasted him with
radio questions, mostly foolish.
Marconi graciously let it be known that he came to the United States "to learn
something about wireless."
Sarnoff disputed this point of the illustrious one-eyed inventor by .stating
that "no one in the United States can teach Marconi anything about wireless."
After having divested himself in good humor of the radio reporters, Marconi was
taken to the roof of Radio City, where he was duly photographed - returning to the
Ritz-Carlton Hotel later, where he spent the night. He then embarked for Chicago,
where he arrived on October 2nd.
Here, a great tribute was paid to Marconi, as the father of radio, at a luncheon
given in his honor at the Museum of Science and Industry. From this he rose, at
Mr. Roosevelt's invitation, to greet the President, with whom he was photographed.
Subsequently, returning to his own luncheon, he said: "The money aspect of the development
of radio must not be forgotten. For example, my first experiment in broadcasting
across the Atlantic cost more than $200.00."
In concluding the ceremonies, Rufus Dawes, president of the exposition, presented
a special medal to Senatore Marconi at the Century of Progress; while a light-beam
from the star Capella, picked up by a telescope in Florence, Italy, and sent by
radio and telegraph to Chicago, switched on the floodlights of the Fair. The inventor
then flashed around the world, by wireless, the letter "S," which thirty years ago
he sent so dramatically across the Atlantic.
Silent Bedlam
A tremendous crash is heard, the grinding of metal upon metal, splintering of
glass, the screams of the heroine; then, the siren of the traffic cops, the roar
of hundreds of actual voices of the dear populace. Shots are fired at the hit-and-run
driver responsible for the crash.
These are the noises that issue forth from your loudspeaker, as you sit in your
study and listen to the latest radio presentation. Vaguely, you picture in your
mind's eye a large room in which all these noises are manufactured, with hundreds
of people being employed to bring it all about.
You are due for a disappointment; because, the next time, if you have a friend
at one of the key stations of a large broadcasting net, you may step into the studio
where all the noise originates, and you will find that here "bedlam reigns" silently.
Everything is very prosaic, and at the most there are only three or four people
in the studio, speaking in moderately low voices. Where, then, is all the noise
coming from?
If you look closer, you will see a long table with about ten phonograph turntables;
one operator sits in front of them. The turntables are all rotating. The operator
merely depresses a push-button, which brings the phonograph pickup down on a precise
spot of a certain phonograph record when the cue is given. This one phonograph record
may give the exact reproduction of the automobile crash, Depressing the next button,
the pickup descends upon the spot which unloosens pistol shots. The next will give
a marvelous reproduction of a roaring crowd. Meanwhile, the operator who pushes
the buttons does nothing but wear a pair of phones and listen to the output of the
phonograph discs. You see, all the pieces have been recorded from actual crashes,
actual crowds, actual shots, etc. When required, an impresario simply orders whatever
"noises" he wants; this is much simpler, much less costly, and the noises can be
used at any time later on. This new scheme has been developed into perfection by
the Camden, N. J., plant of the Radio Corporation of America, and is now in use.
The ease with which the sound effects can be injected into the program by this
method is just one more example of the remarkable development of broadcasting in
the past few years.
Radio Typewriters
Once upon a time, you used to send out-of-town messages by the dot-and-dash method,
as practiced by Western Union. Last year, the great and powerful American Telephone &
Telegraph Company perfected their "Teletype" machines, which they rent to you. Owning
the wire system themselves, they rent you the Teletype machine, which is nothing
but a typewriter, to which a telegraphic transmitter has been attached, and a similar
machine is placed in your Chicago office for the paltry sum of $1.20 for 3 minutes
and 40¢ for each additional minute. A New York merchant can now send all the messages
he wants to his Chicago office, day after day. He couldn't afford to do that by
sending straight messages by Western Union or Postal Telegraph.
Not to be outdone in this line of endeavor, and to make the operation still cheaper,
a number of radio enthusiasts have been working on the radio typewriter for years.
Clyde Fitch, well known to readers of Radio-Craft, and inventor of the Tropadyne
radio circuit, has been active in the development of radio typewriters; and last
month Radio Industries started manufacturing them in a Binghamton, N. Y. plant.
The chief outlet at the present time is the U. S. Army and Navy. It is expected
that large factories, brokers, etc., will use the radio typewriter presently.
Mr. Fitch recently demonstrated it in New York, where it was operated between
uptown and downtown offices on 5 meters, and worked to a charm. It seems to be foolproof
with the exception of one old bugaboo - and that is static. Old Man Static, when
he gets going, is liable to print some letters that were not intended originally;
but, unless the static is exceedingly bad, it doesn't make much difference, because
you can easily spot the incorrect letters. Anyhow, even ordinary wire telegrams
contain misspellings traceable not to static but to clerical mistakes.
