Governance

The ARRL is governed by a member-elected, volunteer Board of Directors. The organization divides its membership into 15 Divisions, each representing a portion of the country. One Director and one Vice-Director are elected by the members of each Division to serve a three-year term. Director elections are staggered so that one-third of the Directors and Vice Directors are up for election each year. The Board of Directors manages policy direction for the organization as a whole.American Radio Relay League (2008)

History


1914–1920

In 1914, Hiram Percy Maxim of Hartford, Connecticut, was a prominent businessman, engineer, and inventor (notably of the Maxim Silencer). He was also an active radio amateur, with one of the best-equipped stations in the Hartford area. One night in April he attempted to send a message to another ham in Springfield, Massachusetts. He had a one-kilowatt station (call 1WH), and Springfield was only away, well within his normal range. He was unable to make contact, and remembering that he knew another ham in Windsor Locks, about halfway, he asked him to relay the message. At that time, the maximum reliable range of a station was a few hundred miles, and so Maxim realized that a formally organized relay system would be of tremendous use to amateurs. Maxim was a member of the Radio Club of Hartford, and he presented a plan for the organization of an "American Radio Relay League" at its April 1914 meeting. The club agreed to sponsor the development of such an organization. Maxim and Clarence D. Tuska, the secretary of the Hartford Radio Club, developed application forms and sent them out to every amateur station they could think of. By September 1914 they had over 230 stations on the roster. In early 1915, disagreements began to surface as to the role of the Hartford Radio Club in the new organization, and in February the ARRL split off from the club and incorporated under Connecticut law. Finances were shaky, and most of the income came from sales of booklets, maps and message blanks. By March 1915, there were 600 stations on the roster, and due to improvements in equipment and operating ability, some of the better stations were claiming communication ranges of up to a thousand miles. It was apparent that the ARRL now needed some kind of bulletin to stay in touch with its members. Maxim and Tuska agreed to personally finance it, and in December 1915 the first, 16-page issue of '' QST'' was sent free to all members. Further issues would be supplied through subscription at $1 per year. In 1916, with ARRL membership nearing a thousand, Maxim set up six trunk lines of relay stations, both east–west and north–south, and individual managers were appointed. Messages were now being relayed over longer and longer distances, and in February 1917 a message was sent from New York to Los Angeles and an answer received in one hour and twenty minutes. In 1917, the ARRL was reorganized to a more formal organization. A constitution was adopted, twelve directors and four officers were elected (including President Maxim and Secretary Tuska), and membership was opened to anyone interested in radio. No sooner had this happened than all amateurs received a letter from the

. During the war the ARRL facilitated the recruitment of amateurs into communications positions with the armed services, but had little else to do since all civilian experimentation with radio equipment was prohibited. In November 1918 the Armistice was signed, but Congress introduced bills to put all radio operations in the United States under control of the Navy. The ARRL strongly opposed the bills. Maxim testified before Congressional committees and the League organized an effective grass roots campaign with thousands of individuals contacting their congressmen in opposition. The bills were defeated, and in April 1919 amateurs were permitted to put up antennas again, but only for receiving. Meanwhile, the League needed reorganization. A financing plan consisting of selling bonds to members was adopted and about $7500 was raised. '' QST'' was purchased from its owner, Clarence Tuska. ARRL continued to lobby Congress for the resumption of transmitting privileges, and after a number of protests and appeals, amateur radio was fully restored in November 1919.


1920–1964

The 1920s saw tremendous technical growth in radio. Pushed both by wartime demands and by the growing commercialization of radio, equipment rapidly improved. The use of spark gap technology quickly disappeared as the more efficient

for the first time. With government uncertainty as to how to allocate both commercial and amateur frequencies, the ARRL kept discipline in amateur ranks so that spectrum was not unnecessarily occupied. They worked with Washington and the result was that amateurs received the orderly series of

frequency bands that they largely hold today (originally 1.8, 3.5, 7, 14, 28, and 56 MHz; other bands have since been added and the 56 MHz allocation was changed to 50 MHz). Other activities during this time included transcontinental relays to quickly move messages across the United States, communications assistance in several emergencies, and encouragement for an amateur radio operator on an Arctic expedition of Donald B. MacMillan—perhaps the first beginnings of DXpeditions. The League also began to act in an advisory capacity for the American delegations at international radio conferences. In 1925 the

band. A controversial idea was originated in 1961 when the League encouraged "incentive licensing", which sought reversion to the principle that higher levels of license privileges should require higher levels of demonstrated knowledge and CW skill but took away some amateur privileges until licensees requalified at higher levels; "incentives" are still in effect and only holders of the highest class of license ( Amateur Extra) maintain all amateur privileges. By 1964 the positive influence of the ARRL was so evident that the United States issued a commemorative postage stamp on its 50th anniversary. As the League prepared for the future a new headquarters building was opened at Newington.

Regulatory advocacy

, arguing that the power lines will radiate interfering radio energy, impeding amateur radio activities. The League has filed several interference reports with the FCC. The ARRL sued the FCC, claiming that the FCC violated the Administrative Procedure Act in creating its rules pertaining to BPL. On April 25, 2008, a US Court of Appeals agreed with the ARRL that the FCC violated the APA, especially by redacting data from the public that could have shed doubt on the FCC's decision. "It is one thing for the Commission to give notice and make available for comment the studies on which it relied in formulating the rule while explaining its non-reliance on certain parts," D.C. Circuit Judge Judith Rogers wrote. "It is quite another thing to provide notice and an opportunity for comment on only those parts of the studies that the Commission likes best."


Services

The American Radio Relay League offers several services to members that support their on-air operations. For members with an interest in DXing, the organization operates both incoming and out-going QSL bureaus for the exchange of QSL cards with stations in other countries. Staff at the organization headquarters maintain and operates station W1AW, the Hiram Percy Maxim Memorial Station, as a living memorial to the "Father of Organized Amateur Radio". The W1AW station is used for regular

) sponsors amateur radio license examinations for the three classes of U.S. amateur license. License classes and examinations are held in various locations throughout the year. Although the FCC currently recognizes 14 different organizations as VECs, the VEC sponsored by the ARRL oversees about two-thirds of all U.S. amateur radio license examinations.


Publications

The ARRL provides dozens of publications and journals to both members and non-members. ''QST'' is the organization's monthly membership journal, named after a Morse code Q signal that means "calling all stations". The organization also publishes two bimonthly magazines of special interest: '' QEX'' for radio electronics experimenters, and the '' National Contest Journal'' for contesting enthusiasts. The ARRL publishes various technical books and online courses. Members of the organization also have access to a special Members Only section of the ARRL web site that includes technical documents, expanded product reviews of amateur radio equipment, expanded contesting information, and a searchable database of all league publications. A flagship annual publication, The ''Radio Amateur's Handbook'', has been published since 1926. The ARRL also publishes a series of manuals designed to assist interested persons in obtaining an amateur radio license or upgrading to a higher class of license.


Contests

The ARRL sponsors numerous amateur radio contests throughout the year with the biggest of these being November Sweepstakes and the International DX Contest. Other contests and sponsored operating events include Straight Key Night, VHF Sweepstakes, UHF Contest, and 10 GHz and Up Contest. The ARRL also participates as a Headquarters station for the IARU HF World Championship. Field Day is an annual event organized by the ARRL that includes both a competitive element as well as an emphasis on emergency communications readiness and the promotion of amateur radio.


Controversy

Criticisms of ARRL have included its support for less strict licensing requirements in the 2000s, which opponents consider a " dumbing down" of amateur radio or making it more like

Other critics have felt almost the opposite, however, arguing that the ARRL was slow to lobby for the removal or the easing of the Morse code proficiency requirements of the various license classes, a "conservatism" keeping otherwise qualified people out of amateur radio and thus threatening its future. Other critics have cited ARRL's support for segmentation of the HF amateur bands in the U.S. by bandwidth, rather than by
