By the
time World
War I ended in November, 1918, almost 5000 amateurs had served in
uniform,
with many giving their lives overseas. Amateurs had proven themselves
to
be invaluable to the war effort. The Army and Navy were faced with an
absolute
lack of trained radio officers, instructors, operators, and even state
of
the art equipment. Amateurs stepped in and provided the knowledge, men
and sometimes even the equipment necessary to help win the war. An
interesting
example of this was the case of Alessandro Fabbri, a wealthy yachtsman
and radio amateur, who had top notch stations on board his yacht and on
Mount Desert Island, Maine. The Navy commandeered the stations (and the
yacht), made Fabbri an ensign, and placed him in command. Largely with
his
own money, he expanded his operation and improved his equipment.
Fabbri's
station was used to pass most of the official communications between
the
battlefronts in Europe and Washington. The traffic often amounted to
20,000
words a day, most of them in cipher. Captain (later Major) Edwin
Armstrong,
whose regenerative receiver was being used worldwide, was in charge of
the Signal Corps' Radio Laboratory in Paris, where he developed the
superheterodyne
receiver. Thousands of amateurs served as Navy radiomen and Signal
Corps operators.
It would seem from the information above
that amateurs had conclusively
proven their worth and that the Navy would return the amateurs'
frequencies back to them once the war had ended. Sadly, this was not
the case. A string
of events conspired against the amateur and almost eliminated all
privately
owned stations.
The villain in this play was the
Secretary of the Navy, Josephus
Daniels, a puritanical landlubber and teetotaler, whose opinions often
got
him into trouble. He was the type of individual that H. L. Mencken and
Sinclair
Lewis satirized as "one who is terrified that somewhere, someone is
having
fun". For years, he had demanded that the Navy have exclusive control
of
the radio spectrum. Now, it appeared, he had his chance.
The effects of the first modern global
war, along with the Bolshevik
Revolution in Russia, had temporarily turned the country extremely
conservative. It was in this mindset that the Espionage Act of 1918 and
Prohibition were
passed. Hundreds of suspected communists and anarchists were deported
in
the "Red Scare". Even the great Socialist Eugene V. Debs was imprisoned
for disagreeing with the government. Seizing the opportunity, Secretary
Daniels urged the passage of legislation giving the Navy a monopoly on
radio
communications. As a result, the Poindexter Bill was introduced in the
Senate, and the Alexander Bill in the House. Political observers gave
both
bills an excellent chance of passing.
Back at the ARRL, things looked bleak.
All memberships had lapsed
(along with all amateur licenses), 80% of the amateurs were still
overseas, "QST" had ceased publication, the unpaid printing bill was
$4700, and there
was $33 in the treasury. However, action was needed immediately to
defeat
these bills. Hiram Percy Maxim and the other board members dug into
their
own personal funds and sent out a "blue card appeal" to all known
amateurs
or their families asking them to write their Congressman and urge
defeat
of these bills. It worked. Thousands of letters poured into Washington
from
amateurs or (more often than not) their family members asking that
amateur
radio be saved. Congressmen who opposed a military monopoly of the
airwaves
also joined in, lending their support to amateur radio. Overwhelmed by
this grassroots opposition to Naval control of the radio spectrum,
Congress
killed the bills in committee. This 1919 letter writing campaign had a
profound
historical impact on all of radio, for, had these bills passed, not
only
would amateur radio have disappeared forever, but all private
communication
activities (such as broadcasting, business radio, CB, GMRS, Cellular,
etc.)
either never would have evolved, or would have been delayed by years or
even decades.
With the bills defeated, Maxim and the
ARRL Board of Directors issued
$7500 worth of bonds to League members to get "QST" going again. At the
same time, pressure was brought on Washington to lift the radio ban and
allow
amateurs back on the air. Partial success was achieved on April 12,
1919,
when the Navy removed the ban on receiving, but not transmitting.
Thousands
of amateurs and other listeners removed the seals from their receivers
(which had been placed there by Government Radio Inspectors), strung up
their antennas and warmed their filaments with the sounds of the
government
stations. But they wanted more. Their fingers fondled their telegraph
keys
as they waited for the lifting of the transmitting ban. Finally, in
November
1919, after a Joint Resolution had been introduced in Congress
demanding
that the Secretary of the Navy remove the restrictions on amateur
radio,
the transmitting ban was lifted, licenses were reissued, and amateurs
were
back on the air.
Now began the "second war", Spark vs. CW.
Remember that amateurs
were allowed, in effect, just one frequency - 200 Meters. A spark
station
on 200 meters actually generated a signal from 150 to 250 meters. With
the
sensitive regenerative receivers now in use, the practical range was
several
hundred miles. Transcontinental relays now took less than five minutes.
The number of licensed amateur operators stood at 5719 in 1920, 10,809
in 1921, and 14,179 in 1922. And all were operating on 200 meters! To
quote
Arthur Lyle Budlong in "The Story of the American Radio Relay League",
it was "Interference, Lord, what interference! Bedlam!". Something had
to be done.
And it was. Various transatlantic tests
were conducted from 1921
to 1923. The results overwhelmingly showed CW was far superior to
spark. Postwar vacuum tube production was at its peak. In 1921, an RCA
5 watt tube cost
$8, and, as a single tube CW transmitter, could outperform a 500 watt
spark
station. A 50 watt tube cost $30, and was five times more effective
than
the best 1 kW spark station. Since CW took only a fraction of the
bandwidth
that spark did, over 50 CW stations in the same area could occupy the
150
to 250 meter range, vs. one spark station.
The transatlantic tests also revealed
some other interesting facts.
Due to the excessive interference on 200 meters, some stations had
dropped
down to 100 meters where, to their surprise, they found conditions much
better. Throughout the 1922-24 period, hundreds of tests and casual
contacts
were made on the 100 meter wavelength which conclusively showed not
only
CW's superiority over spark, but increased range on the shorter
wavelengths.
Once again, the scientists came forward and said that long distances on
100 meters were mathematically impossible, and once again, the amateurs
proved
them wrong. During 1924, several CW contacts were made at distances
exceeding
6000 miles. On October 19, 1924, a station in England worked New
Zealand,
a distance of almost 12,000 miles. Amateur communications had now
reached
halfway around the world. Although it would take a few years to
discover
the role that the ionosphere played in shortwave communications, there
is no doubt that amateurs pioneered the practical uses of shortwave.
The phenomenal success of CW convinced
the vast majority of amateurs
to buy that vacuum tube. A few still clung to their spark sets,
screaming "spark forever", but by 1924, spark was almost extinct. The
150 to 250 meter region was now orderly, filled with thousands of CW
stations living in
peaceful coexistence with each other (and the occasional spark
renegade).
Legally, however, amateurs could not go below 150 meters. True, many
were
already on 100 meters without a problem, but amateurs wanted a slice of
the shortwave spectrum allocated to them. After all, it was amateurs
who
discovered the short waves. Now, with world wide interest being shown
here,
they wanted protection. Negotiations were ongoing with the Department
of
Commerce to give the amateurs specific frequencies.
On July 24, 1924, the Department of
Commerce authorized new amateur
frequency bands. They were 150 to 200 meters (1500 to 2000 kc), 75 to
80 meters (3500 to 4000 kc), 40 to 43 meters (7000 to 7500 kc), 20 to
22 meters (13,600
to 15,000 kc), and 4 to 5 meters (60,000 to 75,000 kc). Except for a
portion
of the 150 to 200 meter band, spark was prohibited. Spark would survive
in the hands of a few rebels until 1927 when it was banned altogether.
CW was here to stay. By January, 1925, the 80, 40, and 20 meter bands
were
filling up with amateurs, drawn by the promise of transcontinental,
daylight
DX.
