Half a Century of Electronics Publishing - 50th Anniversary
50 years ago this month the world's first radio magazine was
launched. It - and those that came after it played an important part in the half
century of electronic progress that followed.
The first issue - Modern Electrics for April 1908.
By T. R. Kennedy, Jr.
half century ago - April, 1908 - Modern Electrics,
the world's first publication designed to explain and popularize "wireless," was
published. Its editor and founder, Hugo Gernsback, was a Luxembourgian who had come
here in 1904 as a youth of 19, to market his first invention, a layer-built dry-cell
With his new battery - which he had patented in Europe - the young inventor brought
many new ideas and devices with him, It was not long, therefore, before a new company
to import, manufacture and market devices for the electrical and the new group of
"wireless" experimenters, made its appearance. Called the Electro Importing Co.,
it occupied a small loft at 32 Park Place, later a larger one at 87 Warren St. and
still later at 84-86 West Broadway, in lower Manhattan; a little later, there was
added a retail store at 68 West Broadway, the world's first radio store.
Among other items, the E.I.Co. began marketing the first home or private radio
ever offered the public. Called the Telimco (from The E.I.Co. name) wireless telegraph
outfit, it was advertised in Scientific American in January, 1906. Sales
were slow at first - the new company had to convince not only the public but the
police that the device would send signals through the air without wires - but it
soon became the most important product of the E.I.Co. The original Telimco model
is now in the Ford Museum at Dearborn, Mich.
Early picture of the Electro Importing Co.'s first retail store
- the world's first radio store - and the type of equipment that was sold before
So much explanatory material was needed in those days to tell about what the
Electro Importing Co. had to sell to electrical experimenters and wireless enthusiasts
that the company's voluminous catalog often contained long explanatory articles.
Gernsback found himself already a publisher of electrical and wireless information,
and it was but a step to a regular monthly periodical.
Though he used the conservative Modern Electrics as a title (a "radio"
magazine pure and simple could hardly have survived in 1908) the very first article
of that original April issue was entitled "Wireless Telegraphy." Another article
"by our Brussels correspondent" described a wireless-equipped automobile. There
was also a piece about long-distance records established by the United States fleet,
whose transmissions from the west coast of Mexico had been received at San Francisco
and at Pensacola, Fla.
The first issue contained 40 pages. Price was announced as 10 cents a copy -
$1 per year.
In the very next issue of Modern Electrics (May, 1908), Gernsback elaborated
on his Telimco dot-and-dash wireless with an invention he called the Dynamophone,
in which the human voice, through a microphone, coupled to a spark coil, transmitted
to a distant receiver enough energy to operate a relay and start an electric motor.
This might be called the great-granddaddy of today's numerous voice-operated systems
now used in oceanic radio and elsewhere.
In subsequent issues he commented on the electric tubes then in existence, based
on the Geissler and Crookes bulbs. July's Modern Electrics carried an article
by V. H. Laughter on "Speaking Arc Lamp," forerunner of the high-power arc transmitters,
the arc flame of which was "modulated" by stepped-up voice frequencies. About a
year later, Valdemar Poulsen developed and announced an arc transmitter that covered
150 miles on first test. Laughter, incidentally, has continued as an author in these
magazines to present times. One of his latest articles (June, 1950) was on "Making
Replica of "the first radio set ever sold to the public," a small
spark transmitter and receiver, now rests in Ford Museum at Dearborn. This set was
demonstrated at the IRE convention in 1954, the last time spark transmission was
authorized by the FCC.
A "loud-speaking telephone," which could be heard without pressing the device
against the ear, was offered by the Modern Electrics Berlin correspondent
in the September, 1908, issue. Actual contact with the ear, and thus the possibility
of picking up germs from the device, was said to be avoided. No other use was foreseen.
The Wireless Association of America was promoted in 1909, to further
the interests of wireless telegraphy and "aerophony" in America. There were two
conditions of membership - American citizenship and ownership of a sending or receiving
set (or both). Lee de Forest was the first president. From the membership of this
organization and the "Swatties," or Society of Wireless Telegraph Engineers, of
Boston, grew the present-day Institute of Radio Engineers, which came into official
being on May 13, 1912.
A prominent article in the May, 1909, issue was entitled "Signaling to Mars."
In those days it was thought that a power of 70,000 kw would be necessary. This
could be supplied, the article pointed out, by focusing many high-power long-wave
stations on Mars from various spots on Earth, synchronizing them to operate at the
same time from a single key.
Not content with pioneering in the new world of wireless, Modern Electrics
boldly attacked the unattainable objective of sending pictures through space. In
an article "Television and the Telephot" in December, 1909, several approaches and
proposals by leading experimenters were described. All included a mosaic of selenium
or other light-sensitive cells as a transmitter and a similar mosaic of small lamps
to form the receiving screen. The state of the art had apparently not advanced to
the point where a synchronized scanning system could even be visualized. Gernsback
proposed a method whereby the large number of wires could be cut down by using different
frequencies and tuned relays, and whereby varying light intensities could be reproduced
with varying current strengths. This was said to be necessary to transmit images
of objects in motion and to give a recognizable image. No patents were taken out
on the device, as it was considered too complicated for practical realization in
the form described.
Modern Electrics, now grown to a circulation of more than 30,000, lent
its issue of April, 1910, to the complete printing of the proposed Burke Wireless
Bill, which was devised to "regulate and control the use of wireless telegraphy
and wireless telephony." This was one of the first actions in the struggle against
Federal attempts to "regulate" the amateur into oblivion or ineffectiveness, in
which the Gernsback publications were to take so active a part.
An early E.I.Co. scene. Not only was manufacturing and shipping
carried on here, but Modern Electrics was edited on the premises too.
In Modern Electrics of May, 1910, it was learned that Bellini and Tosi,
two Italian experimenters at Boulogne, whose work had been reported on in the March
and May, 1909, issues, had devised a system of directing wireless waves in space.
The process could be reversed - incoming waves could reveal the direction from which
they arrived. And so was born one of the earliest direction finders.
In the same month the entire organization moved into a roomy 5-story building
at 233 Fulton St. Celebrating the new quarters, Modern Electrics carried
a leading story from Thomas A. Edison on a new nickel-iron storage battery, which
Edison had toiled 6 years to perfect.
The editor told of his new "Detectorium" in July, 1910. It incorporated a silicon
crystal detector as an integral part of a double-slide tuning coil. The blunt silicon
point, held in a brass cup, contacted the coil wires as the slider was moved to
tune. One actually "tuned with the detector." The issue also noted the formation
of the Wireless Association of Pennsylvania, organized to fight the proposed Depew
Bill, which would have limited the use of the air to commercial wireless interests.
In the April, 1911, Modern. Electrics Gernsback leaped into the 27th
century with the now-classic serialized story "Ralph 124C 41+," which, intended
to give the reader a picture of the distant future, contained a considerable number
of then astounding predictions that have since been realized. Among other things,
it pictured the essential elements of radar, telling how pulsed radio waves could
be bounced off objects near and far, then to return to the sending point to reveal
the distance and direction of travel.
On April 1, 1911, it was announced that the Wireless Association of America had
reached the then phenomenal number of 11,360 members. Somewhat reluctantly, notice
was given that the cost of association buttons had to be raised to 20 cents. In
the August issue Dr. Charles P. Steinmetz, the electrical wizard, discoursed on
"Lightning Phenomena." A page ad in the October issue offered the "best Audion made
in the United States." Price complete on a wooden stand, $4. In the same issue,
Ralph 124C 41+ was seeking his sweetheart, Alice 212B 423, who had been kidnapped
and whisked away into space by a villainous Martian. Ralph was hard on the trail
of the abductor, whom he had located through his "polarized wave apparatus" or long-distance
radar - not so fantastic today as it sounded in 1911.
Early E.I.Co. catalog. These were the ancestors of Modern Electrics,
not only in name but in partial contents.
Membership buttons of two of America's oldest radio associations,
the Wireless Association of America - the world's first - and the Radio League of
America, both organized by Hugo Gernsback.
The US Naval radio station NAA at Arlington, Va., opened early in the year, and
could be heard henceforth around the world, transmitting time signals at noon EST.
On Dec. 11, the Alexander Wireless Bill had been referred to the Congressional Committee
on the Merchant Marine and Fisheries and ordered to be printed. Modern Electrics
carried the full text in the February, 1912, issue. The same issue's editorial practically
wrote a constitution for the American amateur, so closely was it followed in the
Wireless Bill as finally enacted:
"Modern Electrics," Feb. 1912
"There should be 4 bill passed restraining the amateur from using too much power,
say anything above 1 K.W. The wave length of the amateur wireless station should
else be regulated in order that only wave lengths from a few meters up to 200 could
be used. Wave lengths of from 200 to 1,000 meters, the amateurs should not be allowed
to use, but they could use any wave length above 1.000 ..."
Wireless Act of 1912 (Section 15)
Law enacted Dec. 1912
"No private or commercial station not engaged in the transaction of bona fide
commercial business by radio communication ... shall use a transmitting wave length
exceeding two hundred meters or a transformer input exceeding one kilowatt except
by special authority of the Secretary of Commerce and Labor contained in the license
of the station ..."
The publisher announced that with the April issue the price of Modern Electrics
would be 15 cents. On April 14 the Titanic had been sunk at sea. Wireless from the
vessel brought aid and 700 lives were saved, proving the great value of the new
medium. In the April issue Clapp-Eastham announced its Blitzen tuner, and Murdock
its earphones, which, it was said, could bring in signals over 2,300 miles.
But Modern Electrics had about reached the end of a long and important
life as a publication. The last issue was published in July, 1912, and Gernsback
began to concentrate his ideas on something new, a type of publication dealing more
with the affairs of the experimenter.
The Electrical Experimenter
"Long live the amateur, long live wireless!" shouted the opening article of a
new publication, "The Electrical Experimenter," which had long been pondered but
finally was born with the issue of May, 1913. Gernsback had terminated a campaign
on the part of the American amateur in Modern Electrics, but he plunged
at once into the affairs of hamdom in the Electrical Experimenter by publishing
a lengthy but easy-to-read piece on "Building Large Spark Coils." He would not accept
or print advertising matter, an announcement said. The periodical - which at 5 cents
a copy was said to have been produced at a loss - would be strictly a service to
subscribers and customers of the Electro Importing Co.
The assistant editor was Harry Winfield Secor, who had been with Gernsback on
Modern Electrics, and who was destined to be a member of the organization
- with brief interruptions - to the present day.
Lee de Forest in the June, 1913, Electrical Experimenter told of "Recent
Developments at the Federal Telegraph Co." which he said "enjoyed the distinction
of having no press agents."
In the February, 1914, issue, Gernsback reported on his "Radioson" detector,
which was made by fusing a .0002-inch diameter platinum wire into a tube of special
glass so that only the most minute tip of the metal was presented to the electrolytic
solution. It was said to have been some 1,246 times smaller than the best bare-point
Wollaston wire of the day, The wireless wavemeter, one of the fundamental tools
of the art, made its appearance in the Electrical Experimenter of August.
In the spring and summer of 1915, with Europe at war, radio and electronics began
to move faster. On May 7 an SOS from the Lusitania revealed that the vessel had
been sunk by a German U-boat. Wireless dramatically had proven again its usefulness.
In the winter of 1915-16, under the aegis of the Electrical Experimenter,
radio leaders in this country formed the Radio League of America. Its purpose was
to "promote the art of amateur wireless telegraphy and telephony in the US ... to
make available to the Government a complete list of US amateur stations ... pledged
to serve the country in time of national danger or need ... "
First drawing of radar equipment appeared in Modern Electrics
in 1911, to Illustrate a science-fiction story.
There was plenty of opportunity for the magazine to take part in the country's
service, and it carried on a campaign to educate the public - and the Government
- to the dangers posed to the country's neutrality by the large German stations
at Sayville, N. Y., and Tuckerton, N. J, The cover of the August, 1915, issue showed
"Sayville Wireless Receiving German War Report," and the editorial pointed out,
with examples, how simple it would be to send coded messages which would assist
German U-boats to sink enemy (and neutral) shipping.
In the very next issue of Electrical Experimenter came the news that
the Government had closed the station at Sayville, later reopening it with a full
Government staff, Charles E. Apgar, wireless amateur of Westfield, N. J., had recorded
Sayville's messages on wax records and turned them over to Federal authorities for
decoding. These, when played back, furnished sufficient evidence to cause the Government
to close the station.
Meanwhile, the part played by the magazine aroused sharp resentment from the
old Sayville officials. Dr. K. G. Frank, head of the station, wrote a bitter letter
to the editor, the point of which was a little blunted by the fact that by the time
it was printed, the Government had already closed Sayville. Dr. Frank, incidentally,
was later convicted as a German Intelligence agent.
By this time Electrical Experimenter (it was in the spring of 1917)
was carrying a few ads - the de Forest "Oscillion" for $60, Pacific Laboratories
displayed and described double-end vacuum-tube detectors. Crystal detectors were
still in the literature of the day, but many realized they were on the way out.
An editorial on "War and the Radio Amateur," stated that the huge backlog of amateur
operators could be inducted into the country's service at a moment's notice. "What
other country could provide such a vast army of well-trained and intelligent men
as this, whose very multitude is a priceless protection?"
Then on April 6 the US entered the war and President Wilson signed the order
silencing the amateurs for the duration. Many, forthwith, went into the armed forces
as an outlet for their activities. Gernsback promptly gave vent to his imagination
in an editorial on the possibilities of "Shooting with Electricity," or magnetism,
to be more exact. Thereafter, Electrical Experimenter explored many facets of the
expanding use of electronics in warfare.
But for the Electrical Experimenter and its merchandising associate,
the Electro Importing Co., a crisis was at hand. Its business - and inventory -
has been increasing since 1908. Now President Wilson clamped down on the sale of
radio equipment. There was a war on. With a fortune in parts on hand, there was
no one to sell them to. One of Gernsback's first acts was to assemble simple telegraph
outfits. He sold thousands, but this did not take care of the great bulk of apparatus
Then one night he stayed in the factory till 2 am, "rummaging over all the parts
in the shop." Suddenly came the solution to the dilemma. He would assemble sets
of lamps, batteries, keys, phones and other electrical components into a neat little
box called "The Boy's Electric Toys." Sitting up late several nights, he compiled
a 32-page profusely illustrated booklet of "100 Electrical Experiments" that could
be performed with the outfit. This little publication may well have been the most
important one the organization ever printed. With its aid the shelves were cleared
and the day saved for the E.I.Co. and, of course, Electrical Experimenter.

Sayville wireless messages were recorded may be seen at right.
The editorial of January, 1919, was entitled "Electric Music." It predicted telephone
receivers covering every audible tone, with almost any required amount of loudness.
Thus was anticipated the current world of high fidelity, the loudspeaker without
a horn and the high-power amplifier to drive it. Even electronic or "concrete" music
In the February, 1919, issue, Electrical Experimenter began a series
of articles entitled "My Inventions" by Nikola Tesla. To persuade the great Tesla
to write his own autobiography was no mean feat, and the editor still looks back
on it as his greatest journalistic beat. The series ended in the May issue, with
the author stating confidently that his proposed system of wireless transmission
of power, temporarily defeated, would finally become a "triumphal success."
With the war over, the question of "regulating the amateur" came up again. The
65th Congress proposed to amend the Alexander Wireless Bill, but the proposed amendments
forbade so many things essential to the amateur that the editor was moved to lampoon
the bill in a bitter cartoon in the February Electrical Experimenter. The bill was
killed. The hated demon had been effectively exorcised by :he power of the cartoonist's
pen and of the printed word.
The Acting Secretary of the Navy announced that, effective April 15, 1919, all
restrictions were removed on radio receiving stations other than those used for
reception of commercial traffic.
The opening of the broadcast era was at hand, and the Electrical Experimenter
wrote of this and other marvels to come, in the January, 1920, issue. Among this
bewildering maze of wartime inventions and discoveries, none was more dramatic in
operation than the radio compass, described by Pierre Boucheron. It used a large
Kolster coil or loop rotated by a handwheel to which was attached a compass card.

In July, 1919, Gernsback had begun a new publication, Radio Amateur News,
It was his first strictly radio publication, "the logical outcome," he went on editorially,
"of many attempts to put out a purely radio periodical, independent throughout and
devoted to American Radio Amateurism." He explained that in 1908 he had started
the "first magazine in America-Modern Electrics - in which many radio articles
appeared, but radio amateurism then being in its infancy could not support a purely
radio magazine." For that reason Modern Electrics devoted about one-quarter
of its content to radio. Then came the Electrical Experimenter in 1913,
"which had been more prominent than any other on account of its very important radio
section. Even during the war, with amateurism dead and nearly every radio magazine
discontinued, Electrical Experimenter at great financial loss continued
radio articles uninterruptedly, month after month, to keep alive the radio spark
in the hearts of our amateurs."
But with the war won and a new law defeated that would have killed amateurism,
he wrote, "we will witness the most wonderful expansion the radio arts have ever
dreamed of. I predict an astounding growth in the next 10 years."
Electrical Experimenter had, for some months, been carrying on its cover
a second title - "Science and Invention." In August, 1920, Science and Invention
became the official name, leaving Radio Amateur News to cover prac-tically
all the wireless material formerly handled by it. Electrical Experimenter-Science
and Invention carried tremendous prestige and was immensely useful. During
its life - till 1929 - it was virtually the electrical and experimental bible for
countless youngsters and grownups - the primary stimulus for many a future career.
The famous "Verboten" cartoon, said to have been an important
factor in defeating the amended Alexander bill, which would have destroyed amateur
radio as we know it.
The October, 1919, Radio Amateur News carried a stop-press bulletin
that "all restrictions on amateur radio are removed," and a longer mention appeared
in the November issue. The world of the ham operator would resume its pre-war status
under the Department of Commerce.
Inspired by the great possibilities of remote control of all kinds of systems
by radio, the June, 1920, Radio Amateur News pointed out that "vast fields
remain to be tapped in this category." The work of John Hays Hammond Jr. in this
new field, the editorial stated, mystified those who watched torpedoes and small
craft maneuvering without visible means of control. Radio, of course, was doing
it, by transmissions from hidden shore stations. After June, 1920, the word "Amateur"
dropped out of the name, and the magazine became simply Radio News.
In April, 1921, a full-page ad announced Cunningham power tubes, type C-302,
5 watts output, price $8. Incidentally, RCA Radiotrons UV-200 and UV-201, the "best
detector" and "best amplifier," sold for $5 and $6.50, respectively. The first annual
Amateur Radio Show and Convention was staged at New York's Pennsylvania Hotel Roof
The first religious broadcast came over KDKA from the Calvary Episcopal Church,
Pittsburgh, on Jan. 2, 1921. The 200-kw Alexanderson alternator went into service
at Tuckerton, N. J., the same month. KDKA carried the first boxing match - Johnny
Ray vs Johnny Dundee, on April 11, and that station also broadcast the first theatrical
performance from the Davis Theatre May 9.
In an experiment conducted early in 1922 at the request of the Italian Government,
a portrait of King Victor Emmanuel was transmitted by facsimile equipment devised
by Dr. Arthur Korn. Dr. J. H. Miller of the Navy's Radio Research Bureau devised
a radio-frequency amplifying system with a range of 800 to 20,000 meters (375 to
15 kc), "with some gain as low as 150 meters" (2,000 kc ) .

Broadcast stations on the air by August, 1922, reached 227 and, by December,
569 Radio News reported. Major Armstrong announced his superregenerative
circuit on June 28. By August, WEAF, New York City, was sending from the Telephone
Co. Building in lower Manhattan. That same month it broadcast the first sponsored
program ever put on the air - 10 minutes for $100 - sponsored by the Queensboro
Corp., to sell real estate.
January of 1923 saw the first "network" broadcast, a 3-hour hookup of WEAF in
New York City and WNAC in Boston. Dr. J. A. Fleming, the great British inventor
of the Fleming valve rectifier, began a series of articles in February. It was titled
"Electrons, Electric Waves and Radio Telephony."
It was a period of great concept and invention. Prof. Louis A. Hazeltine described
his soon-to-be-famous Neutrodyne, based on a mathematical principle, to the Radio
Club of America. An editorial in the August, 1923, issue pointed out the tremendous
field of research open to the radio amateur on waves between 1 and 10 meters, "where
static almost vanishes, and new and unsuspected phenomena await the experimenter."
Some 600 variable condensers were on the market at one time in that period. All
had to bear the label "low-loss" or they wouldn't sell. Louis Gerard Pacent created
one of the first of the new order of inductances. He called it the "duo-lateral"
and pronounced it the most efficient ever.
On the cover of Science and Invention in November, 1923, Gernsback showed his
Osophone, the first bone-conduction device with which the deaf could hear through
Another invention ("the only patent that ever brought me in any money") was filed
for patent on Sept. 27, 1923. It was a variable condenser, comprising " ... a condenser
plate, secured on the base ... and a cooperating resilient plate ... means for flexing
the resilient plate." In clearer language, it was the compression capacitor, now
used almost universally as a trimmer, to track the sections of a variable capacitor
gang. The device was sold to Crosley and was used as a "book condenser" in the Crosley
Patent drawing of the compression capacitor; prototype of today's
In Radio News in December, he advocated a "single-knob control" for
radios, adding that "one of these days" we will tune in with one knob ("and possibly
an additional one for volume") and get along without all the multi-control paraphernalia
of the usual receiver of the day. He had visited the television laboratory of C.
Francis Jenkins and called what he saw there the "most marvelous thing of this age."
Crude television, but impressive then.
Maj. Edwin H. Armstrong had brought back from his wartime service in the U.S.
Army in France an unusual receiver called the superheterodyne. It outshone all others
for sheer sensitivity and selectivity. Those who dared could buy the diagram and
parts and build one of these "supers" - if they had the skill, patience, time and
sheer luck. This was the heyday of the hookup, and Radio News published
accounts of them all. Experts and nonexperts built the Reinartz, the super, the
Autoplex, the Solo dyne, the Neutrodyne and scores of others that caused sleepless
nights to thousands of tinkerers. Even Radio News had its pet circuit,
called the Ultradyne, and told the story of its development in February, 1924. It
was an improved superhet, devised by the associate editor - Robert E. Lacault -
and gained wide popularity.
The oscillating tube appeared in a new role - a producer of music - with the
Staccatone, conceived by Gernsback and developed for him by Clyde Fitch. It consisted
of a Hartley oscillator with a large tapped inductance consisting of several 1,500-turn
honeycomb coils. The instrument's keys were connected to the taps, and two large
capacitors could be switched in to increase the range. It was used as a 2-note interval
signal on WRNY (a very useful device at a time when a station might be silent a
few minutes between selections without announcement or' apology) and was apparently
the first interval signal to be used so. The musical 16-note instrument had been
heard on the air before - over WJZ in November, 1923, and had been demonstrated
in conjunction with an orchestra under the direction of Dr. Hugo Riesenfeld. Its
construction was described in the March, 1924, issue of Practical Electrics.
In May, 1924, H. C. Harrison of Western Electric Co. received a patent on the
electrical recording of sound, greatly increasing the tonal quality of the phonograph
record. Western's sister company, Bell Laboratories, worked out an improved acoustic
phonograph with an exponential horn to take advantage of the new electric recordings,
which could not be heard to full advantage on older phonographs, In March, 1925,
a contract for commercial use of the new recording method and the new phonograph
was signed with the Victor Talking Machine Co., and in November the new Orthophonic
line of phonographs and the new records were put on the market. At practically the
same time, Brunswick offered an electrical phonograph; the Panatrope, with a pickup
designed and manufactured by General Electric, in which records could be played
through an amplifier, an improvement even on Victor's new acoustic Orthophonic system.

A regular 6-city broadcast network was set up with WEAF as the key station in
October, 1924. It had increased to 12 cities by the spring of 1925. Thus was networking
During the '20's, when it was hard to supply all the information needed in the
new art, new publications were welcomed and read avidly. Beside the Experimenter,
Gernsback published an annual Radio News Amateur's' Handibook, which ran
from 1923 to 1929, and Radio Review, "A Digest of the Latest Radio Hookups," ran
from 1925 to 1927, when the hookup craze had started to die down. Radio Internacional,
which was Radio News in Spanish, ran through 1926 and 1927. Radio Listener's Guide
and Call Book was published in 1927 and 1928 as a quarterly, giving broadcast stations
and shortwave transmitters. There was also the Radio Program Weekly around 1927
- the only weekly ever published by the organization. Television, the world's first
TV magazine, came out in two annual issues - 1927 and 1928. Later, in 1931 and 1932,
a bi-monthly, Television News, was also to be the only television magazine of its
Books as well as periodicals were also in demand. The organization had been printing
books since 1910, when the first call book of amateur stations was printed under
the sponsorship of Modern Electrics. The Electric Library, whose second publication
was the one-time famous The Wireless Telephone, published from the earliest days.
During the Electrical Experimenter period it gave way to the Experimenter Library,
a title that proved so popular that it was revived in the 1920's for a new series
of books. These were usually small, stiff paper-covered works dealing with simple
radio subjects. Gernsback in 1922 wrote a larger work of 291 pages, entitled Radio
for All, which was published by Lippincott.
In November, 1921, another new magazine, Practical Electrics, was announced.
Beginners were finding Radio Amateur News a bit over their heads most of
the time, and the new magazine was slanted to "the electrically inclined layman,
the electrical professional man, the experimenter, the student and the beginner."
In 1924 the name was changed to The Experimenter, and the magazine continued
to February, 1926. It was then merged with Science and Invention, which carried
on a number of its departments for the experimenter and student.
The Experimenter of November, 1924, envisioned a military "radio television
plane" which would fly without a living person aboard. Its movement would be controlled
by radio from the ground. The plane would be equipped with "eyes" to look in six
directions at once. Miles away, and safely behind the lines of the battlefront,
the control operator would be able to inspect what was taking place in the plane's
vicinity better than an aviator in the plane could do. The radio-controlled craft
could be directed to reconnoiter, or to drop bombs on the enemy. It was a fantastic
picture of warfare then, but by no means so today viewed from the vantage point
of some 35 years of technical progress.
In January, 1925, Radio News began the story of Prof. Reginald A. Fessenden.
It was perhaps one of the most important autobiographies in radio literature. He
is credited with more than 300 inventions, without which the art today would not
be what it is. In the issue of January, 1925, Dr. Greenleaf W. Pickard, one of the
most consummate experimenters of his day, described his discovery of the oscillating
crystal, giving the credit for it to Dr. W. H. Eccles. The average Radio News
was a big periodical by now-200-odd pages in the April issue, with a monthly print
order of 400,000 copies.
The regenerative Interflex receiver, using a diode detector in
the grid circuit of the first audio tube.
There were 564 broadcast stations in the country by June, 1925, operating on
100 channels. Crowding was a big problem, but with time-sharing and geographical
separation there were channels for 550 stations. Then the broadcast band was extended
downward and 100 more channels came into use. As a result, 800 stations operated
under conditions short of ideal because high-quality transmission was being used,
and 10-kilocycle separation was not adequate for best reception. Radio News
explained the situation editorially. New sets would be made to bring in the extended
channels, but existing receivers could do nothing about it economically, if at all.
In July, 1925, Radio News launched its own broadcast station, WRNY, which
later (in 1928) achieved the distinction of being the first broadcast station to
Then came a new idea in radio. It was the ac tube, chronicled in Radio News
of June, 1925. A low voltage was applied to the filament from a transformer, through
terminals at the top of the tube which could be plugged into the sockets of a battery
receiver. These Kellog tubes disappeared when more advanced ac types arrived.
In Radio News of September, 1925, Gernsback described a rather unusual
receiver of his own development. It was a four-tube single-dial tuner with a crystal
in the grid circuit of the second tube, which would normally have been a grid-leak
detector. He called this receiver the Interflex and stated that his detector-amplifier
stage gave "great amplification with unusual stability of operation," The Interflex
was later improved by balancing the rf stage and in December, 1925, the "Regenerative
Interflex" was described. It had the crystal in the grid circuit of the first tube,
with a tickler coil to produce regeneration, thus combining rf and af amplification
in a single tube, with a direct-coupled diode detector.
This picture from the Experimenter, in 1924, was the first description
of military television. A remote-controlled plane was represented as being equipped
with television cameras looking in the four directions as well as up and down, and
the scenes would be projected on a six-paneled screen at general staff headquarters.
The spring of 1926 had come. "What in your opinion will be the next great development?"
the editor of Radio News was asked one day. "Undoubtedly," he replied editorially
in the May issue, "it will be the ability of man to see objects at a distance -
any distance. Why not? Through practically the same medium-radio - we hear from
all over the world!" He went on to describe television - today's television - at
considerable length, and visualized whole networks of stations operating from a
single program source, "capturing with the utmost detail all the features of a face
or landscape, with sound of highest quality."
When remarks attributed to Edison charged that "radio is a commercial failure
with waning popularity," the editor of Radio News flew to its defense,
pointing out that interest is "steadily increasing" and that "radio dealers are
now making money." Radio sales in 1926 alone would top $520 million.
The National Broadcasting Co. was formed by RCA on Dec. 9, 1926. RCA had purchased
WEAF in July, taken over its 18-city Red Network, and in December added the WJZ
Blue Network. The World Series that fall had been carried by the Blue Network, as
the Yankees and Cardinals fought it out. The Edison Phonograph Co. had released
a 12-inch disc capable of playing 22 minutes - the world's first long-playing record.
"Hello, London! Are you there, New York?" And thus - on Jan. 7, 1927 - went 2-way
trans-Atlantic voices over the first overseas radiophone service ever offered for
public use. Single-sideband transmission was used. The preliminary story on the
project had been carried in Radio News of December, 1925, and a complete report
given by G. C. B. Rowe in the March, 1927, issue.
"Can We Radio the Planets?" was the title of a Gernsback article in the February,
1927, issue. It was proposed to erect a powerful beam transmitter on one side of
the earth, bounce signals off the moon or planet, and pick up the signal at a station
on the opposite side of the earth. This forecast became a reality 19 years later
when US Signal Corps scientists first established radio contact with the moon. Interestingly,
the January, 1958, Proceedings of the Institute of Radio Engineers, in an article
"Lunar Radio Echoes," refers to this early article as the first serious proposal
to send signals to other heavenly bodies "and return."
Thus went the round of invention and development. John L. Baird, Scottish inventor,
described his television system at Glasgow, Scotland. A Washington's Birthday address
by President Coolidge was carried by a 50-station network from a joint session of
Congress. Wire television was demonstrated between Washington (D. C.), New York
and Whippany, N. J., by the Bell Telephone Laboratories. Secretary of Commerce Hoover
spoke at the Capital City and was seen and heard at this end. Later in 1927, the
Labs demonstrated color television.
"When broadcasting was established in this country," Gernsback wrote in an editorial
for Radio News of July, 1927, "the universal opinion was that it would
always be free." And thus he disposed of the question of "wired vs space radio,"
venturing that toll radio would always be a challenge to the ingenuity of builders
to overcome it and get something for nothing - the bootlegger would take what he
The first "portable radio," an RCA superhet of the middle '20's.
In the November, 1927, issue of Radio News, the publisher disclosed
for the first time a new principle in receiver construction called the Peridyne.
It embodied a new method of "shield tuning" designed to bring the various rf stages
into perfect interstage alignment, hence to operate at maximum possible efficiency.
He did this by placing above the coil a metal disc that was moved up and down with
a threaded rod. The so-called "slug" or "shield" thus compensated for inequalities
in the inductance of the tuning coils, raising or decreasing the inductance in accordance
with its distance from the turns of the coils. The Peridyne principle is the first
use of nonferrous slugs or plates as tuning or trimming devices, and introduced
the service technician to the screw-adjusted trimmer.
True ac-operated sets began to come on the market in the spring and summer of
1927. RCA had announced the ac-heated 226 and 227 tubes early in 1927. By the end
of the year the ac era had arrived, and several articles in the November issue of
Radio News confirm that fact. The Columbia Broadcasting system went into
operation in September, 1927.
Radio News of January, 1928, announced that the double-grid tube had
arrived, calling it "probably the only real advancement ... since the invention
of the triode." The tube had enjoyed tremendous popularity in Europe, but had been
neglected here. Double-grid tubes had been described "for years in this magazine"
and had been used in the Solodyne, which eliminated the B-battery.
The Peridyne receiver, which introduced nonferrous trimming slugs
for coil tracking.
The electrodynamic cone loudspeaker was developed by the Bell Telephone Laboratories
and demonstrated in April, 1928. Radio News carried the news at that time
and touched on it again in November issue. The device revolutionized techniques
of sound reproduction. Twenty-one manufacturers were putting out such units by late
1928. Installed atop a New York office building, one dynamic speaker was heard three
miles away on the New Jersey shore. So great was their popularity that stores could
not get them fast enough, and reproduction was considered faithful from the lowest
to the highest tones in the range of human hearing.
"During the past few months," editorialized in Radio News in September,
1928, "a new era seems to have opened that will be known hereafter as the 'Shortwave
Cycle.''' Short waves, it was explained, are not new, having originated back in
the days of 1908 when amateurs began first to converse with each other on waves
below 200 meters with dots and dashes. Marconi, in October, 1927, speaking at the
Institute of Radio Engineers, had predicted that the short waves "are destined to
be vital in radio and television." The editorial went on: "As time passes the interest
in short waves becomes greater and greater ... It would not surprise me at all if
during the next 5 years, both sight and sound would be transmitted completely on
short waves, and the upper channels from 200 to 600 meters were abandoned completely."
The Radio News station 2XAL, WRNY's transmitter on 30.91 meters, which
had started in the spring of 1928, "had poor reception within 200 miles of New York,
but beyond that it gets better and better."
Start of Radio-Craft
In the spring of 1929, Radio News, Science and Invention,
Amazing Stories and associated magazines, were sold to other interests.
Radio News of April, 1929, was the last Gernsback issue. In July of the
same year he created a new magazine in the fields of the set builder, shortwave
fan, radio serviceman and amateur. He named it Radio-Craft. It would devote
itself to the experimenter and constructor, he editorialized, noting that in the
United States and Canada there were some 250,000 to 350,000 active radio enthusiasts.
Radio-Craft would not carry "re-hash stuff," but new material, "edited
first, last and always for its readers."
Under the heading "the Constructor," the first issue of Radio-Craft
carried a story about the "Supreme Power Amplifier" which had two CX-350 tubes in
the output stage. Another story was on the "Harkness Screen-Grid De Luxe." The magazine
also described the Pilot "Super-Wasp," which became one of the most famous shortwave
sets, in an article by John Geloso (now one of the leading Italian manufacturers
of electronic and hi-fi equipment). Other authors included Jack Grand, H. G. Cisin,
Clyde J. Fitch and Charles Golenpaul.
Marconi's early "microwave" equipment. Apparatus with parabolic
antenna at left is transmitter; that at right the receiver.
The permanent-magnet dynamic speaker made its appearance in 1931. It was recommended
for use with battery portables - scarcely anyone then foresaw it as the universal
speaker it is today.
In June, 1930, Short Wave Craft magazine had begun. It noted the huge
buildup of the art, which "promises to assume large proportions in the years to
come." In the June-July issue of 1931 it was reported that 7-inch waves had spanned
the 21 miles of the English Channel between Calais and Dover, and that amateurs
were blazing trails with contacts throughout the world. The boys were getting started
on channels as short as 5 meters. A 15-watter had been heard almost around the globe.
With the May issue of 1937 the publication had a new name - Short Wave and
Television (later Radio and Television), and combining the fields
of the shortwave and television experimenter, had the largest circulation of any
such periodical in existence. In the May issue, John V. L. Hogan, who then owned
and operated New York City's WQXR, wrote on "Short Wave Broadcasting." The publication
continued to dominate the radio-video field until 1941, when it was merged with
One of the decisive tube inventions of the early 1930's was the "variable-mu"
(also known as super-control or remote-cutoff) tube. It could be biased to control
rf gain gradually, hence was a highly effective device in automatic volume control
circuits. It also eliminated cross-modulation, a bad feature of earlier screen-grid
rf tubes. Based on the variable spacing of grid wires, it was the invention of the
late Stuart Ballantine of Boonton, N. J.
Gernsback Publications put out an Official Radio Service Manual late in 1930,
collecting for the service technician many hitherto unobtainable schematics of the
sets he had to service. Editions followed annually, and in July, 1933, a Consolidated
Manual, combining the first three volumes. was announced. One of the most important
and valued radio documents of the day, it sold more than 80,000 copies.
Meanwhile, British tube makers had produced Catkin metal tubes, and American
manufacturers were quietly experimenting with the metal types.
In 1932 the Radio-Craft Library appeared. This was a collection of practical
radio books, some of which were made up of material from the magazine. They were
larger than most of the earlier books published by the organization, running about
64 pages. Subjects ranged from radio set analyzers to frequency modulation. The
library ran to 28 books and suspended in 1941, due to war shortages. Some of these
red-covered booklets are still to be seen in old-timers' collections. Short
Wave Craft published a number of blue books on shortwave construction and operation.
One of these, on coil winding, was so useful to the constructor that inquiries for
it are still received occasionally.
In February, 1933, Radio-Craft announced "The Greatest Set of the Year,"
a complete ac-dc receiver which could be held in the hand. The famous International
Kadette opened an age of table midgets, though its size (8 5/8 x 6 1/2 x 4 inches)
would not be startling today. Indeed, it was a three-way portable, for it could
also be used with a 6-volt (auto) battery and B-batteries! The set, incidentally,
was not a superhet-c - it had one stage of rf, power detector, an audio stage and
a small mercury-vapor rectifier which had been designed for automobile B-power units.
Radio-Craft of December, 1933, carried a feature article on an even
smaller set, called the "Kaydette," by the same company. It sported two tubes and
an indoor antenna.
A typical radio store of the mid-'20's. It was operated by United
Cigars - believe it or not. The same company had four service stations in New York
City. Brown Bros. Photo
Elaborating further on his Osophone of 1923, Gernsback described in Radio-Craft
of March, 1934, a later idea in the field, the Phonosone. It was a Baldwin balanced-armature
loudspeaker phone attached to a headphone headband and worn against the forehead,
permitting vibrations generated by the output of a radio to be transmitted to the
bones of the head, to lighten the world of the deaf and near-deaf. The Osophone
was the first description of a bone-conduction hearing-aid unit. In the July issue
was a story on a light-sensitive device worn on a strap around the neck. Equipped
with a battery and buzzer, it would help guide the sightless.
An editorial in Radio-Craft of August, 1934, noted that the television
"picture is still pitifully inadequate," going on to remark that "as long as we
cannot have an image at least a foot square of excellent detail that can be viewed
in broad daylight, it is obvious that the television set has not arrived."
Radio, meanwhile, had grown into a multi-million dollar industry - RCA alone
in May, 1935, announced plans to spend $1 million for field television tests. The
radio servicing industry had grown likewise. The July, 1935, issue announced that
"the service business has advanced to where it must now be recognized as a separate
industry, its dollar sales are in the millions." Estimates from all sources "have
established the amazing figure of some $30 million in labor costs alone in 1934."
Added to equipment costs this swelled the total to $45 to $50 millions annually.
"And this is only the beginning."
Metal radio tubes, similar to those we now have in the shops, came from American
tube makers in the middle 1930's. October Radio-Craft of 1935 carried an
exhaustive semitechnical story about their design and capabilities. Glass tubes,
then, appeared to be on the way out. However, in Radio-Craft issues of
late 1936, 16 or more new receiving tubes were pictured and described. Only one
was a true metal tube.
"Good servicemen need not be worried about the quackery practices by the so-called
'gyps' of the game," who were "outnumbered and certainly would be eliminated," editorialized
the July, 1937, issue, pointing up to present-day readers that the gyp apparently
always has been with us. The same issue reported that the Department of Commerce
had installed ultra-shortwave fan type markers to aid air traffic at landing fields.
A special, more than double-size number of Radio-Craft in March, 1938,
celebrated the 50th anniversary of radio as dated from the production of the first
radio waves in 1888 by Heinrich Hertz. It was filled with articles on the progress
of radio, its early history, memoirs of old-timers, and included a few predictions
for the future. The most striking feature was the illustrations, which depicted
radio equipment and installations from the earliest days. Numbers of the better-established
radio companies reprinted advertisements that had appeared originally nearly two
decades before. Not the least valuable contribution made by the "Jubilee Issue"
was the preservation of historical material in some of the articles and the old-timers'
reminiscences, some of which would be hard to uncover today.
The International Kadette, earliest of the true small ac-dc radios.
The best news of summer, 1938, came - television-wise - when the NBC revealed
plans to broadcast 5 hours of visual programs weekly. Pictures were 441 lines, with
a 5 to 6 aspect ratio (10 by 12 inches, said July's Radio-Craft).
Meanwhile, at the convention of the IRE, Vladimir Zworykin and R. R. Law of the
RCA Laboratories had projected pictures on an 8 x 10-foot screen.
With the July, 1939, issue 10 years of uninterrupted publication of the magazine
had been completed. Gernsback wrote: "I take this occasion to voice our heartfelt
thanks to the thousands of loyal followers of the magazine and to the large majority
of those who have read it through all these years. Radio has come a long way since
then. In 1929 we had no pentodes, no variable mu, no metal tubes, no tuning eyes,
no octal, loctal or acorn tubes, no black-and-white cathode-ray tubes that finally
made television possible."
A. P. King of the Bell Labs had demonstrated that megaphone horns could launch
15-cm waves along a wire over distances to the horizon, adding in the November,
1939, issue that the fidelity of transmission was "flat within 1 db over a bandwidth
of 250 mc," enough to carry 40 or 50 TV channels. Dr. George Southworth of the same
organization was experimenting with coaxial cables and waveguides, and told stories
about removing the inner conductor of a quartz-insulated cable without affecting
the efficiency of transmission, and then of removing the outer conductor, allowing
the microwave signals to be "conducted" by the insulating quartz alone.
By early 1940, frequency modulation had earned for itself an almost permanent
niche in the Monthly Review department, as the continuing progress in that field
was appraised. Much experimental work was going on. Major Armstrong's Alpine (N.J.)
station W2XMN had been on the air for some time. On Oct. 31, 1940, the FCC issued
the first commercial FM licenses. The December issue carried an ABC primer of FM
prepared by authorities.
FCC's special authorization for use of Gernsback spark transmitter
at 1954 IRE exhibition. Note that this 1906 equipment was well up in the vhf range.
In the issue of March, 1942, Radio-Craft carried some 30 pages devoted
entirely to what leading American radio engineers thought about FM and its future.
Major Armstrong wrote a lengthy piece. The New York Times paid a million dollars
odd for WQXR and W2QXR. The NBC had installed its FM station - W2XWG - atop the
Empire State Building. There was a station on Mount Washington, N.H. The radio map
of FM was rapidly filling up.
But most radio activity was grinding to a stop because of war duties and war
shortages. The service technician was compelled-and urged as a patriotic duty -
to keep America's receiving sets operating without new tubes or components Radio-Craft
instituted a special Wartime Radio department, beginning in the August-September,
1942, issue. Articles began to appear on servicing volume controls, rf coils and
other components formerly replaced. There was even a story on "Wartime Transformer
Rewinding" and the long series of tube-replacement articles began with "War-time
Tube Replacements" in February, 1943. Dozens of such articles - and even a few books
- were printed. The service technician became adept at substituting practically
every tube in the manual, and even repairing a few!
About this time, with the US in the middle of World War II, the ugly head of
"radio censorship" made its appearance and Wendell Willkie demanded: "Let's not
have any more of this nonsense." Radio-Craft, editorially, echoed those sentiments
in December, 1942. Dr. Lee de Forest, father of radio, had celebrated his 70th birthday
at Los Angeles on Aug. 26, 1943, and his comments on radio in general were printed
in the October issue, following the anniversary.
Nikola Tesla, possibly the greatest inventive mind of all history, died Jan.
7, 1943. The next issue of the magazine printed a complete article on the life and
inventions of the almost-forgotten genius who had given us our now-universal alternating
current, had pioneered in high-frequency, radio remote control and in power transmission
by viscosity of liquids, but had in most cases seen his patents run out long before
society was technically able to put them to work. Expressions of appreciation from
the leading figures in the electronic world indicated that more than one had cut
his scientific teeth on the Inventions, Researches and Writings of Nikola Tesla,
published in 1894.
Beginning with the May issue of 1943, the Radio-Craft cover had begun
to show the name "Radio-Craft and Popular Electronics," advertising that the periodical
would henceforth cover the ramifications of the broader field. A monthly section
headed Electronics was carried thereafter in all issues, and grew rapidly in size
and importance. One of the first comprehensive stories therein covered the evolution
of the Klystron, and a serial "Practical Electronics" had begun under the authorship
of Fred Shunaman, then associate editor.
The Age of Television
On August 21, 1945, the FCC lifted its wartime ban on one amateur band - 112-115.5
mc. The other bands were freed Nov. 15, permitting some 60,000 stations to resume
operation after 4 1/2 years of silence. In November, RCA announced that postwar
TV sets, priced from $200 to $450, would be available in 6 months. Other manufacturers
were following suit. By September, some 515 FM stations had been applied for, also
129 TV transmitters and 265 AM outlets.
The book-publishing division of the organization picked up in 1946 where the
Radio-Craft Library had left off. Under the title of Gernsback Library,
a number of smaller paper-covered books were printed. Starting in 1951 with Frye's
Basic Radio Course, larger, cloth-bound editions were printed, with such excellent
results from the viewpoints of both publisher and reader that smaller books were
dropped almost entirely, and only full-length works printed, though they can still
be obtained in paper-covered as well as cloth-bound editions.
Large-screen television of 1939. The tube stands upright, projecting
an image upward to a mirror on the slanting cabinet lid, from which it is reflected
to the viewing screen.
The 40th anniversary of the invention of the vacuum tube by Lee de Forest was
marked by a special issue of Radio-Craft of January, 1947. The inventor
was then 73 and still inventing. Articles by de Forest himself, Frank E. Butler,
his chief aid during the inventive years of the early 1900's, and others who remembered
or were associated with the birth of the Audion, were included.
Radio-Craft in January, 1948, published its first Special Television
Number. It was the first of 10 annual television issues, the earlier ones of which
especially filled a need for detailed and consolidated information which could not
be obtained elsewhere. The special TV issues were discontinued only when such information
became general and easily available.
On June 30, 1948, the Bell Telephone Laboratories announced and demonstrated
the transistor, a crystal that could amplify an electric current like a vacuum tube.
The discovery was heralded throughout the world and was the subject of a feature
article "End of the Vacuum Tube?" in the September issue. Treating the coming of
the transistor later (in the January issue of 1949), Gernsback declared: "It will
play an increasingly important role in the future. When we look back at the humble
beginning of the crystal detector, we marvel at the spectacular comeback it has
made in the form of the new transistor, destined some day to supplant the vacuum
Late in the spring of 1948, a letter had been addressed to the older subscribers
by the publishers. The name Radio-Craft no longer seemed to be the proper
name for a publication that had so much to do with the modern world of electronics.
"Would the readers suggest a new title?" And so Radio-Craft, at the end
of 20 years of existence, became Radio-Electronics with the issue of October, 1948.
Gernsback promised that the publication would ever be in the forefront of radio-electronic
happenings the world over.
One of the first articles in it was about the new LP microgroove phonograph record
announced by CBS and Columbia Records to the newspapers in the spring of 1948 and
discussed subsequently at technical meetings.

Radio waves had long been directed through the air and carried over wires, and
much experimenting had been done with more advanced methods of guiding those of
ultra-high frequency. In its December, 1948, issue Radio-Electronics told
the story of the microwave guide, which channeled the uhf waves like water through
pipes. This was a project of the Bell Labs at its Holmdel, N. J., field laboratory,
based on pioneering work done for years by Southworth and others. The work is still
going on at Holmdel - with round guides - and is considered one of the most promising
fields of research for the future of long-distance communication.
Television was getting into high gear in the spring of 1949. "When broadcasting
began in 1920 it engendered the first major radio boom, but now we are in the middle
of another similar cycle," commented Radio-Electronics editorially in March.
"This time it is television that is gaining rapid momentum. The difference is that
the present boom will make the first look small by comparison." As of Jan. 1, the
editorial pointed out, only 1,037,000 homes were TV-equipped and the public had
paid some $432,429,000 for sets. Authorities had predicted that in 1949 the public
would own a minimum of 2 million sets at a cost of some $650 million. "All in all,
it will be seen that television will enrich our economy by $1 1/2 to $2 1/2 billions
By Jan. 1, 1950, 98 TV stations were operating in 24 cities. Noting TV's advantages,
the Navy had begun to use it in teaching.
The January, 1948, issue had carried a short note on the American Telephone &
Telegraph Co.'s plans to connect New York and Boston telephone-wise by microwave.
Experimental transmissions had been made as early at Nov. 13, 1947, with Washington
hooked in by coaxial cable. On May 1, 1948, this circuit was inaugurated as the
Bell System Eastern Network. A Midwestern network opened Sept. 20, and on Jan. 11,
1949, the Eastern and Midwest networks were linked, extending the system from the
East Coast to St. Louis. Sept. 4, 1951, saw the beginning of coast-to-coast television.
Radio-Electronics reported in October, 1949, on a new lightweight printed
circuit introduced in the Telex model 200 hearing aid. It was some 1 x 2 inches
in size and with all components weighed 1 1/16 ounce. How to build a see-in-the-dark
Snooperscope with war-surplus materials was described and pictured in the same issue.
Radio-Electronics noted in December, 1950, that the FCC had picked the CBS sequential
color TV system as standard for the country. It had been tentatively approved on
Sept. 1, but now was finalized and commercial broadcasting had begun Nov. 20. An
estimated 7 million sets then in the public's hand would need an adapter to tune
in the programs correctly and convert to color - the cost per set: $125 to $150.
Calling the FCC decision a "bombshell" to the TV industry, Gernsback editorially
called it "Choleric Color TV," stating that "color television should be allowed
to develop naturally," just as radio did. "To use forceps to force a premature birth
may mutilate the color TV child for life." And most of the TV industry agreed.
"Electric Spaceships" was the subject of an article by the German rocket expert,
Prof. Hermann Oberth, who touched on the use of electrical repulsive forces to drive
the rocket into space. It ran in the December, 1950, and January, 1951, issues.
Once free of the earth's atmosphere, he went on, "we can then build machines which
collect energy from the sun ..." At the time the article was considered almost fantasy
(but fantasy backed up with rigid mathematics) and even Gernsback would scarcely
have dared to predict that by 1957 we would have a space vehicle in flight.
Phonevision, the first proposed toll TV system, was advocated by Zenith. Subscriber-Vision,
engineered by Skiatron, had also been undergoing tests over New York City's WOR-TV.
The picture was given an electrical "jitter" by the transmitter in both these systems.
It could be taken out at the home receiver by a call to the phone operator or by
inserting a special card key that introduced a correcting voltage.
By May, 1951, television and the various subjects associated with it were occupying
a clear majority of the pages of the magazine. Ultra-high frequency was the keynote
of the national IRE convention summarized in the June Radio-Electronics. In the
same issue it was announced that Western Union had organized a television service
outfit. Opening shop first in New Jersey, it would handle Du Mont installations
and do service work in several counties at rates commensurate with Du Mont's regular
charges. Radio-Electronics treated the topic editorially in the July issue. Conclusion:
Western Union "has still to learn the business, and that they cannot do overnight."
The furor subsided.
Oldest member of the staff
One of the oldest members of the staff is the invisible Martian office boy, Mohammed
Ulysses Fips, who in the early days of Modern Electrics had his own department,
The Martian Spark. Now, grown to a grave and long-bearded consultant, member of
many learned societies with unheard-of name, he confines himself to the description
of one wonderful discovery a year, usually in the April issue. These range from
a radium-operated one-tube receiver, so powerful that it needs a throttle rather
than a volume control, to a means of keeping an office quiet by picking up the noise
with a microphone, amplifying it and reproducing it at equal volume, but opposite
phase, to the original sound. Thus complete silence would result. Fantastic, when
published, but patented within 2 years by one of the country's greatest acoustic
researchers. Other ostensible April Fool stories were trial balloons, stories of
things a little too far-fetched to be predicted with confidence, but which might
or should be invented. Such was the Westinghouse 1933 vest pocket receiver, so ridiculously
small for the time as to arouse the indignation of engineers, but a clumsy and bulky
set by today's standards, or Electronic Brain Servicing, screamingly funny in 1950,
but quite serious when described in July, 1956, as manufactured by Lavoie Laboratories.
The silver tribute awarded to Hugo Gernsback by the radio-electronics
industry in 1953.
"A radically new type of teaching now becomes possible," Gernsback editorialized
in the September, 1951, Radio-Electronics. Television had now made many
things possible that were not easy before. With television in all public schools,
wired with a city TV Education Center, 50 brilliant teachers could reach the city's
800,000 students, whereas, with the usual system, 35,000 teachers were needed.
An editorial in the November, 1951, issue pointed out that "the radio-electronics
industry will soon be one of the top three" in the country, ranking next to steel
and aircraft production. More than $7,600,000,000 in electronic contract's will
have been awarded by the year's end, Dr. Allen B. Du Mont reported.
Tape recording, a new field of the electronics industry, had been growing rapidly.
In the August, 1952, issue it was noted that newspaper opinion held that a "revolution
was taking place in the science of capturing and reproducing sound" and was being
used widely in many fields - entertainment, business, education and professional.
The January, 1953, issue - the sixth annual television number - noted editorially
that as the issue went to press "the first closed-circuit telecast of the Metropolitan
Opera was about to be carried to a number of theaters.
In April, 1953, Gernsback predicted that "intercontinental TV programs are feasible."
He added that the idea was not original with him - Baird had actually bridged the
ocean with images as early as 1928 but with low frequencies - present-day TV used
high ones. It would be necessary "to build many relay stations to skip from island
to island" over any large bodies of water. Where natural islands were not available,
"iron islands" in the form of steel caissons are advised for the relays.
In the April issue there was also an article on a new German electrostatic speaker
- not a new idea exactly, but a new design. In June, the editorial told of a new
"booming field for video-closed-circuit television," which, the editorial went on,
"is certain to rise in the next 10 years to unimagined heights." Du Mont had produced
three-dimensional or stereoscopic TV for use in atomic research.
In May, 1953, several hundred leaders of the electronics industry awarded the
editor and publisher of Radio-Electronics, at a Radio Industry Banquet
in Chicago, a trophy, a large sphere cradled in rare metals, mounted atop a handsome
silver base set in ebony. The whole stands 27 inches high. On it were engraved the
names of his many friends and associates (33 firms and 97 individuals) who contributed
to the award, as well as the names of 75 living and dead "immortals" in the field
Part I of a series of special articles on "High-Quality Audio" began in the September,
1953, issue. An important -feature of the series, it was said, would be to go beyond
the purely technical details and treat the subject as an extension of the art of
music in general, as one would like it in the home. Richard H. Dorf was the author.
The FCC, which had granted a limited tentative approval to the NTSC compatible color
TV system in midsummer, now brought the year to a happy close by granting full approval
on Dec. 21, thus opening the door to our present system of color TV broadcasting.
Use of the G-Line, invention of Dr. Georg Gobau of the U.S. Signal Corps, was
described as an ideal facility for long uhf-TV transmission lines in the March,
1954, issue. The pros and cons of "High-Fidelity Loudspeakers" were discussed in
this and subsequent issues by the British authority, H. A. Hartley. The August issue
carried a Bell Laboratories story on the solar battery, which operated a small transmitter
and was the first practical attempt to obtain real electrical power from light.
About the Author
To prepare an article of this type required an unusual combination
of qualifications - expert knowledge and wide experience in the fields both of journalism
and electronics, Radio-Electronics found this combination in Tom Kennedy, recently
retired associate radio editor of the New York Times. His acquaintance with radio
goes back to 1907, when as a high school student he assembled a crystal set from
parts bought from the E.I.Co. (following it up the next year with a 12-inch spark).
He studied electrical engineering at the Carnegie Institute of Technology in Pittsburgh,
then worked on radio compasses, first as Radio Compass Officer in the Navy (World
War I) and later as civilian employee, installing equipment on more than 50 destroyers
and a dozen land stations. He was radio editor of the Pittsburgh Post and Sun and
technical radio editor of the Philadelphia Evening Ledger before joining the Times
in 1927. Since his retirement Mr. Kennedy has done some consulting work in high-fidelity
(his activities in the high-fidelity and amateur recording field were the subject
of an article in Fortune, October, 1946) and free-lance writing in electronics and
"'How foolish we once were,' our children will say in future, 'to allow our great
scientists to speak to only a few dozen, or perhaps a few hundred pupils when the
great man could lecture to 500,000 at the same time,' " Gernsback editorialized
in the February, 1955, Radio-Electronics on the topic of "Tec-Teleducation,"
the substance of which he had proposed as far back as December 1950 in "Newspeek,"
a prognostic spoof on the times. "Fortunately," he went on, "we have in our hands
today the means of making Teleducation a reality in the immediate future ... Just
as we have a national closed-circuit TV network, there will be a similar one for
grade and high schools, colleges and universities, covering the entire country ...
Teleducation will not displace our teachers - it will supplement and augment them."
More than 42,000 radio engineers registered at the 1955 national convention of
the Institute of Radio Engineers. Ultrasonics was one of the chief subjects. It
drilled teeth painlessly and was useful in internal diagnostic work. RCA exhibited
a new tri-color vidicon tube, and Du Mont displayed the Iconumerator, which counted
a million small objects in the twinkle of an eye.
In the August Radio-Electronics was a story of reliable TV "scatter"
communication over 188 miles between Holmdel, N. J., and the Round Hill station
of the Massachusetts Institute of Technology, near New Bedford, Mass. Sixty-foot
antenna "dishes" beamed the 4,000-mc waves over the horizon, and scattered bits
were recovered at the receiver and reproduced as the complete image.
The Philco "Apple" cathode-ray tube for color reception was described in the
last special television issue, January, 1957. It is a 21-inch single-gun device
coated with a repeating array of red, blue and green stripes arranged vertically.
The term "Apple" is a Philco code word and has nothing to do with apple characteristics.
The picture-on-the-wall TV tube, which had been predicted for some time by many,
"has at last reached the advanced laboratory stage," reported Eric Leslie in the
March, 1957, issue. The account was from English sources and described a flat tube
in detail. Others in this country are experimenting with similar devices and have
pooled their patents with the British developers, the article revealed.
Dr. H. C. Ko, of the radio observatory of Ohio
State University, wrote in August, 1957, about the 96-helix radio telescope being
used there to sound outer space for galactic signals, and gave some hints to would-be
radio astronomers. The Solion and the Spacistor-new amplifiers neither like tubes
or transistors - were described in the November, 1957, issue. An editorial about
the same time wondered about, them, and what would come after them, but closed on
the note: "The greatest scientific discoveries still lie in the future - the art
has barely begun!"
