On November
2, 1920, Warren G. Harding was elected President of the United States.
Millions read the election results in the newspapers the next day. In
the
Pittsburgh area, however, hundreds heard the election returns the
moment
they were wired in, thanks to Dr. Frank Conrad, a Westinghouse
employee,
who broadcast the results over 8XK, his amateur station. This station
would
evolve into KDKA, and the night of November 2, 1920 has been called the
start of the multi-billion dollar broadcast industry. But was it? This
month "The Wayback Machine" looks at the evolution of broadcasting, and
the amateur's role in it.
The idea of broadcasting was first considered by Lee deForest in May,
1902,
when he wrote that "Ultimately, wireless telephony will be possible".
He
urged the financial backers of the deForest Wireless Telegraph Company
to
develop and patent the concept. The stockholders, however, were more
interested
in immediate profits (through massive stock sales) rather than genuine
development, and refused to finance the necessary research. Undaunted,
deForest
in 1907 formed the deForest Radio Telephone Company. In a statement
that
for 1907 must have appeared radical and even bizarre, but was amazingly
prophetic,
he wrote, "I look forward to the day when opera may be brought into
every
home. Some day the news and even advertising will be sent out over the
wireless telephone".
Despite deForest's intense interest in this area, he was not the first
to
broadcast the human voice and music over the airwaves. That honor
belongs
to Reginald Aubrey Fessenden, a Canadian Professor. He was the first to
recognize the inherent flaw in the concept of spark transmissions, and
set
out to find an alternative. His quest led him to Schenectady, NY, and
the
services of General Electric's most brilliant scientist, Charles
Steinmetz. Fessenden explained his idea: an alternator capable of
generating waves
of 100,000 cycles per second (3000 meters). Steinmetz and his
assistant,
Ernst Alexanderson, worked for almost two years, and finally produced
an
alternator that met Fessenden's requirements. The Alexanderson
Alternator,
as it was now known, was delivered to Fessenden's station in the Fall
of
1906. On the evening of December 24, 1906, ship and amateur operators
heard something in their headphones they had never heard before:
someone speaking!
A woman singing! Someone reading a poem! Fessenden himself played the
violin.
(The Alexanderson Alternator would play a prominent role in early high
power
stations and will be fully covered in a column exploring Schenectady's
contribution
to the development of radio and television).
Not to be outdone, deForest continued his radio telephone experiments
in
the period 1907-1910, broadcasting from the Eiffel Tower and live from
the
stage of the Metropolitan Opera, where Enrico Caruso was singing.
However,
all of these transmissions had a major problem: without a pure, stable,
direct current CW carrier to modulate, all the signals had a background
whine and distortion. Real development in the area of modulated
carriers
would have to wait until Armstrong discovered the oscillating
properties
of a regenerative circuit.
By 1916, both Armstrong's circuit and the Audion were widely
circulating
in the radio world, and broadcasting surfaced again. Lee deForest
resumed
his transmissions, with programs of "good music, culture, and
lectures".
deForest can be credited with two "firsts" in 1916; the first
advertisements
(for his Audion and other products), and the broadcast of the
Presidential
election between Woodrow Wilson and Charles Evans Hughes.
(Unfortunately,
deForest signed off before the California results were in, so he
declared
Hughes the winner over Wilson).
Also, in 1916, amateur station 2ZK broadcast one hour of music each
night.
David Sarnoff, who had manned his station during the Titanic disaster,
also
got into the act. He wrote a memo to his employers at American Marconi
suggesting
a "Radio Music Box", which would become a "household utility". He went
on to describe his vision of radio broadcasting, and then turned to
finances.
He predicted an income of $75,000,000 or more each year from the sale
of
receivers. Marconi, still focusing on ship to shore telegraphy, took no
action on the memo.
After amateurs had returned to the air in November 1919, hundreds of
them
began to explore the area of broadcasting. In May, 1920, amateur
station
8XK joined many other hams in the transmission of music. Incidentally,
it
WAS LEGAL for amateurs to broadcast music, news, sports, lectures,
advertisements,
or indeed just about anything else they wanted. The Radio Act of 1912,
still
in effect, did not mention "amateurs", rather, one paragraph made a
general
reference to individual private or commercial stations. The only real
restriction
was the 1 kw power limit and the 200 meter wavelength. After that, the
government didn't care. Thus, those amateurs who had built equipment to
modulate
their CW transmitters eventually played a phonograph record or two,
sang
(or tried to sing), or broadcast some form of entertainment.
With all of the above documented evidence, why is November 2, 1920
considered
the start of broadcasting? The answer lies not at the transmitter, but
at
the receiver. Prior to that night, all broadcasts had, in effect, been
from
one amateur to another, or to a commercial station. The November
broadcast,
though, was designed and promoted by Westinghouse as a transmission to
the
general public. Starting in September, stores were selling basic
receivers
for $10.00 to receive 8XK. Westinghouse, in effect, had seized
deForest's
and Sarnoff's idea, and was marketing it to the general public. Thus,
it
was the makeup of the listening audience that defined the start of
broadcasting.
When the word of this successful transmission got out, more amateurs
got
into the act and set up their own little broadcast stations. By the end
of 1921, it was estimated that about 1200 amateurs had made at least
one
broadcast. Some had a regular schedule of programs and would evolve
into
commercial stations, others did it just out of curiosity. But there
were
listeners. Over 400,000 people heard the Dempsey-Carpentier fight on
July 2, 1921. Radio sales were approaching 100,000 per year, not
counting crystal
sets which were selling at the rate of 20,000 per month. However, with
this
explosive growth came two problems for the amateur.
The first was an identity crisis; what should the role of the amateur
be
in broadcasting? Some thought we should stay out of it and just stick
to
traffic handling on CW. Others envisioned the amateur as a jack of all
trades,
expert CW operator and relay station, as well as community broadcaster.
In fact, a new name evolved to describe this amateur/broadcast hybrid,
"Citizen"
radio or wireless. Even QST was confused; for a period of time in 1921,
the word "Citizen" replaced "Amateur" on the front cover.
The other problem was frequencies. Everyone - amateur, broadcaster and
hybrid
- was on 200 meters. Tuning across the dial in 1921, one would mostly
hear
CW, a few spark holdouts and the new broadcasters. While the amateurs
were
used to the interference, the general listening public was not. They
had
purchased their radios to hear music, not CW. Complaints started to
pour
into the Secretary of Commerce. Legally he was powerless, as the Radio
Act
of 1912 offered no solutions. A conference was called for all
interested parties, held in Washington in February 1922 to try to
resolve the impending
crisis.
Even though he was exceeding his authority under the Radio Act,
Secretary
Hoover was able to get the following proposals accepted at the
conference:
1) Henceforth, special broadcast licenses would be issued. Two
frequencies
would be available for broadcasters immediately, 360 meters (833 kHz)
for
regular transmissions, and 485 meters (619 kHz) for crop reports and
weather
forecasts. 2) After the marine interests had abandoned the 220 to 545
meter
range (1363 to 550 kHz), it would be turned over to broadcasting. 3)
Broadcasting
was forbidden by amateurs, who were defined for the first time by name
as stations operating "without pay or commercial gain, merely for
personal interest". 4) "Quiet Hours" were imposed on all amateur
stations effective from 8:00 to 10:30 PM daily, and on Sunday morning.
The fact that the number of broadcast stations dropped from 1200 to 30
immediately
after these regulations went into effect shows just how many amateurs
were,
in fact, pioneer broadcasters. This agreement, however, was a house of
cards. Secretary Hoover has stretched his authority under the Radio Act
of 1912 well past the breaking point. In 1926, the cards came tumbling
down, and the "Summer of Anarchy" was ushered in. How would amateurs
fare
with no enforceable regulations in place? Join us next time as "The
Wayback
Machine" explores the events leading up to the creation of the Federal
Radio Commission.
