Amateur Radio After World War One (1919-1924)
Although there was concern that amateur radio stations would not be allowed to return to the airwaves after the war, in 1919 the wartime restrictions were ended. And the next few years would see tremendous strides, as amateurs adopted vacuum-tube technology and began to explore transmitting on shortwave frequencies, which resulted in significant increases in range and reliability. However, although they had laid much of groundwork that led to the development of broadcasting, in early 1922 amateur radio stations were explictly banned from making entertainment broadcasts.
Although the transmitting ban on amateur stations wasn't lifted until October 1, 1919, restrictions on private and amateur listening ended on April 15th of that year. Probably no one was happier than Hugo Gernsback, editor of Electrical Experimenter, who celebrated the end of wartime restrictions in his magazine's June, 1919 issue, telling readers in Amateur Radio Restored to expect exciting advances, because "the war has changed everything, for now the radio telephone has come into its own". A feature article by F. A. Collins, which appeared in a number of newspapers, including the August 31, 1919 Seattle Daily Times, declared that Now the Boy Wireless Can Get Busy Again . With the restoration of their hobby, amateur radio operators worked to reestablish themselves. Meeting of the N. E. Wireless Association, from the July, 1919 Radio Amateur News, told how a government District Radio Inspector spelled out the standards to be followed in order to get back on the airwaves. However, some amateurs were guilty of bending these rules. In the April, 1920 Radio Amateur News, Pierre H. Boucheron warned in Two Hundred Meters and What it Means about the need for amateurs to adhere to government requirements, and in particular to "Keep your transmitter on the lawful side of 200 meters". A later article by Boucheron, from the May, 1922 Radio Broadcast magazine, told how an Ohio amateur's sister was Found by Radio after her brother transmitted requests for information about her whereabouts.
Immediately following World War One, the Navy Department attempted to gain a complete government monopoly over all radio communication. That effort failed, so the Navy began to develop ideas for promoting interest in radio, since amateurs were a ready reserve of operators. To that end, on October 5, 1919, a Navy station in New York City inaugurated a nightly broadcast of "various items of interest to the amateur", in order to "maintain the interest of radio amateurs and to train them in receiving code", as reported in Navy to Broadcast News for Benefit of Amateurs, from the December, 1919 Popular Science Monthly. In 1922, Radio News began to print monthly summaries of these transmissions as filler -- the Daily Amateur Radio Broadcast messages for April appeared in the July, 1922 issue. The Wireless Don'ts section of the 1922 edition of A. Frederick Collins' The Radio Amateur's Handbook contained 95 cautions and words of advice, such as "Don't throw your receiving set out of the window if it howls", and, reflecting the superiority of the new vacuum-tube transmitters, "Don't think you have an up-to-date transmitting station unless you are using C.W.", before closing with, "Don't think you are the only one who doesn't know all about wireless. Wireless is a very complex art and there are many things that those experienced have still to learn."
Before broadcasting became popular in the early 1920s, the term "amateurs" referred to all non-professionals interested in radio, including those who merely listened to radio transmissions, which were still mostly in Morse Code. It was only after broadcasting to the general public became common that "amateur" would generally come to have a narrower meaning, of persons who held amateur radio transmitting licences. In 1920 the DeForest Radio Telephone and Telegraph Company issued a promotional pamphlet titled "How To Set Up An Amateur Radio Receiving Station". Company president Lee DeForest authored a section, The Fascination of Radio Telegraphy, which noted that because "the Government has removed all war restrictions on the use of wireless by Amateurs, there are thousands more who are already 'listening in' on Radio news, or preparing their apparatus and getting ready for the biggest wave of popularity that Radio Telegraphy has ever experienced". Persons learning about "the coming science" could set up a radio receiver to overhear "Messages that can be picked up by anyone long before they reach the general public through the newspapers." DeForest also extolled "If you haven't a hobby--get one. Ride it. Wireless is of all hobbies the most interesting. It offers the widest limits, the keenest fascination, either for intense competition with others, near and far, or for quiet study and pure enjoyment in the still night hours as you welcome friendly visitors from the whole wide world." (However, some might have warned that DeForest's advice to "ride" the amateur radio hobby could lead to obsessiveness. In his 1911 The Library of Work and Play: Electricity, John F. Woodhull cautioned "How to have compelling interests without riding hobbies is the great problem for both boys and men. As both prevention and cure of the wireless telegraph mania, my method was to encourage my boy to have several hobbies which he might ride with enthusiasm, but to make it a rigorous rule to exchange his 'mount' occasionally.")
BAN ON BROADCASTING BY AMATUER STATIONS
As entertainment broadcasting began to gain popularity, a number of amateur radio operators decided they wanted to use their transmitters to join in the fun. However, broadcast transmissions by amateurs eventually met with federal disapproval. Effective December 1, 1921, the Department of Commerce had formally established regulations setting aside 360 and 485 meters (833 and 619 kilohertz) as the standard wavelengths for a new classification of broadcasting station, operating under the Limited Commercial licence category. Then, in January, 1922, the department further announced that it was "temporarily" banning the growing number of entertainment broadcasts being made by amateur stations. The February 1, 1922 Radio Service Bulletin reviewed the Broadcasting restrictions, and stated that the department was investigating rules for re-establishing amateur broadcasts, but these revised rules never appeared, and ever since amateur radio operators have been restricted to experimental work and point-to-point communication with other amateur stations. However, due to their technical skills, many amateurs became employed as engineers at the rapidly burgeoning ranks of commercial broadcast stations.
ADOPTION OF VACUUM-TUBE CONTINUOUS-WAVE TRANSMITTERS
The development of vacuum-tube equipment helped to greatly advance amateur radio -- a March, 1921 QST article, Progress, reviewed how over the previous nine years the transmitting range covered by amateur Ralph H. G. Mathews in Chicago, Illinois had increased from only 4 to nearly 3,000 miles (from 6.4 to 4,800 kilometers). Crystal detectors were supplanted by far more sensitive regenerative and superheterodyne vacuum-tube receivers, meanwhile, vacuum-tube continuous-wave transmitters began to replace "King Spark". The better equipment led to successful transatlantic transmissions in 1921, and continued exploration of shorter wavelengths would soon lead to a huge increase in nighttime transmission range and reliability. In 1922, J. O. Smith, operator of Special Amateur station 2ZL, reviewed the ongoing progress in Modern Radio Operation, beginning with the Continuous Wave Transmission by Amateurs section -- this review included Paul F. Godley's prediction that "the day is almost here when spark stations will be of interest as having to do with history only". That same year, Charles William Taussig's The Book of Radio included a chapter, What the Amateur Has Done in Radio, which reviewed the post-war activities plus future goals for amateur radio, and showcased the expanding activities of the American Radio Relay League.
In 1914, Hugo Gernsback predicted, in "A Sermon to Parents", that "Electricity and Wireless are the coming, undreamed of, world-moving forces". Ten years later, with the expanding radio industry now "34th on the list of all the industries in this country", the prospects were even brighter, so Gernsback updated his remarks in the December, 1924 Radio News, and in Your Boy and Radio declared that "Radio to the youth is the best possible foundation of the future self made man."
|"There was a time when the activities of the amateur were a source of irritation to the government. Steps were taken to eliminate him, but they were unsuccessful. At the outbreak of the war, the government found thousands of amateurs ready for radio service. Among the many groups of people who claim credit for having won the war, the author wishes to include the amateur radio operator. There are many pursuits which men and women follow, outside of their regular business or profession. No hobby is more suitable for people in general than radio."--Charles William Tassig, The Book of Radio, 1922.|
