I start this
column
in an attempt to research three major questions that have been asked:
° When did ham radio start?
° Who was the first ham?
° Where did the word 'ham' come from?
To answer these questions, let's set "The Wayback Machine" to Warp
Factor
9, and head back 100 years.
Practical "wireless" had its start in
1896,
when Marconi first sent a signal over a distance of two miles. By 1899,
he succeeded in sending a wireless message across the English Channel,
a
distance of 32 miles. The year 1899 also marks the first construction
project,
which appeared in "American Electrician" magazine. In December, 1901,
Marconi
was able to bridge the Atlantic, a feat which caught the world's
attention
and fueled the imagination of thousands of potential amateurs, who took
their first steps into wireless.
In the early days, everything was
"spark".
What exactly was spark? Well, sit down some summer night, listen to
your
AM or SW radio, and count the static crashes. Now turn on the vacuum
cleaner,
or an electric shaver, and listen to your radio again. Hear that noise?
In short, spark wireless was merely a form of "controlled static". A
high
voltage inside a spark coil would jump across a gap, which was coupled
to
an antenna. The spark was keyed on and off to transmit the code. The
signal
generated was extremely broad. A "state of the art" 1906 spark
transmitter
operating on 400 meters (750 kHz) would actually generate a signal from
about 250 meters (1200 kHz) to 550 meters (545 kHz). Receivers were no
better.
Before 1912, all systems were basically unamplified detectors. Tuners
were
primitive or nonexistent. As might be expected, by today's standards,
the
early wireless stations were terribly inefficient. Transmitting ranges
varied from as little as 600 feet with a 1/2 inch coil to perhaps 100
miles
from a kilowatt station and a 15 inch spark coil. Ships at sea with 5
KW transmitters might get as much as 500 miles maximum range.
It was into this world that the early
amateurs
ventured. Actually, if we were to concentrate on the years prior to
1908,
it would be more appropriate to say "experimenters" rather than
"amateurs".
For in the first decade of wireless, there was little or no interest in
personal communications with other stations; rather, the concentration
was
on technical development, either in the interest of pure science, or
(more
often than not) with an eye towards cashing in on this new medium.
Experimenters
were unorganized and, with the exception of those immediate stations
with
whom they ran tests, had no knowledge or interest in other pioneer
stations. Any true "amateurs" prior to 1908 have been lost in
pre-historic obscurity.
By 1908, however, the face of wireless
began
to change. Technical developments had reached their first plateau, and
a
number of major competitors had formed the first "wireless
trust"--United
Wireless. With a temporary truce in effect, equipment was now more
readily
available to the public. Along with this, new magazines, such as
"Modern
Electrics," were formed with wireless communication as the primary
thrust.
The circulation of "Modern Electrics" jumped from 2,000 to over 30,000
in
just two years. The year 1908 also saw the first "handbook", "Wireless
Telegraph
Construction for Amateurs." It is difficult to know exactly how many
amateur
stations were on the air in this completely unregulated, laissez-faire
era, but reliable estimates put the number of "major" stations (i.e.
those capable of communicating over 10 miles) at 600, while "minor"
stations with
a one or two mile range probably numbered 3000 or more. Thus, if a year
had to be arbitrarily chosen as the start of amateur radio, it would
probably
be 1908.
As for the "first" amateur, that's a
harder
one. Without licensing, regulations, or a written record, there will
never
be a definitive answer to this question. However, "The Wayback Machine"
has come up with the name W.E.D. Stokes, Jr. He was a founding member
and
the first President of the first amateur radio club--the Junior
Wireless
Club, Limited, of New York City. This organization was formed on
January
2, 1909. Other founding members who might lay claim to the title "first
amateur" were George Eltz, Frank King, and Fred Seymour. Later the same
year, the Wireless Association of America, and the Radio Club of Salt
Lake
City were created.
By 1910, wireless clubs were springing up
all over the country, and the first callbook -- "The Wireless Blue
Book"
--was published. Since there were no regulations in this period, the
callsigns
listed in the "Blue Book" were self assigned--which brings us to our
third
question--where did the word "ham" come from? Legend has it there was a
phenomenal station on the air with a 5 KW transmitter, which could be
heard
at all hours of the day and night at distances of over 500 miles. The
station
operator used his initials for his callsign - H.A.M. I don't know if
this
is the real story, but I've always liked this explanation best.
Amateur radio continued to grow. By 1911,
"Modern Electrics" had a circulation of 52,000, and there were 10,000
amateurs
in the country. With thousands of stations on the air, both amateur and
commercial, interference was becoming a serious problem, especially in
marine
communication. Ships, because of their restricted antenna length, were
limited to frequencies between 450 and 600 meters (666 to 500 kHz). As
we have seen, one spark station could take up this entire spectrum.
Thus,
it was imperative that all stations cooperate and stand by when the
others
were transmitting. Sadly, this often was not the case. In addition to
interference
between amateurs and commercial stations, there was more interference
and
sometimes deliberate jamming between commercial stations of different
companies.
Prodded by the Navy (which was using inefficient and outdated equipment
and thus suffering from excessive interference), Congress was starting
to take a serious look at wireless regulation. However, before they
could
take up proposed legislation, an incident happened that would quickly
and dramatically alter the structure of the wireless spectrum.
On April 15, 1912, the R.M.S. Titanic
struck
an iceberg in the North Atlantic and sank. Thanks to wireless, and the
first
S.O.S. in history, 713 lives were saved. However, it has been argued
that
the number of survivors could have been doubled or even tripled, if
there
were stronger wireless regulations in effect. We are going to leave
"The
Wayback Machine" hovering over the year 1912, keeping a sharp eye on
the
Titanic, and on a 22 year old experimenter in Yonkers, NY, who would
soon make some major contributions to radio.
So, until then, keep that spark gap
adjusted
and those raspy CQs coming. We'll catch you next time on board "The
Wayback
Machine."
