1923 __ Interference problems in broadcasting by public
‣ Comment : Radio Experts Talk Problems. — Will Discuss Ways to Combat Interference in Broadcasting by Public. — WASHINGTON, Mar. 20 -- Experts in the radio field and government officials concerned in its extension met here today at the call of Secretary Hoover to consider various problems that have arisen, particularly with a view to interferences in broadcasting by the public. The preliminary presentation of views by the government representatives, officials of radio associations, manufacturers and broadcasting station operators, the conferees went into executive committee sessions for consideration of a new scheme of allocating bands of wave lengths. Failure of the last congress to enact regulatory legislation, Secretary Hoover said at the outset of the conference, has made necessary voluntary cooperative and administrative assistance to establish rules. The objective, he said, is to guard against taking steps which might hinder the development of an infant science and to extend the usefulness of it which, he said already has enlisted 588 broadcasting stations and perhaps as many as 2,500. The government might be willing to relinquish part of the present monopoly of them and lengths between 600 and 1,600 meters, indicated, should the conference so determine while Major General George O. Squier, army delegate said the military authorities would take a liberal view of proposals to reduce their radio scope. C. F. Jenkins, in charge of the government experimental work in the transmission of photographs by radio, declared that within a short time research workers hoped to perfect even transmission of motion pictures and asked special consideration for the operation of such devices. Commander Bingham, naval representative, warned against favoritism of broadcasting of amusement by radio which might interfere with its necessary utility in the operation of ships and aircraft and W. A. Wheeler, for the Agriculture Department, asked protection for farmers in the use of radio, in receipt of market, crop and weather reports.

Commissioner Carson of the Commerce Department's bureau of navigation, acting chairman of the conference, said a day or more might be necessary before the conferees could solve all of its problems. The primary object will be to parcel out among users new and less conflicting bands of wave lengths, and to prescribe operating conditions which will allow commercial services, broadcasters, marine navigators, the army and navy and amateurs to be less hampered in their operations. Problems put before the conference today ranged form the direct notice given by American composers, through J. G. Rosenthal, as counsel for the American society of Composers, Authors and Publishers, that they would strive to extend the copyright laws to give them royalties from radio broadcasting concerns, to the plea of Texas cattlemen for protection in the wireless launching of stockyard reports to give them a knowledge as to whether packing centers were ready for their livestock shipments. Operators of broadcasting stations, whose conflicts are considered most serious, argued for various rulings. Commissioner Carson indicated that the conference considered that voluntary agreement of radio users to its decisions would be depended upon after its work is finished. It is possible, however, that President Harding will be asked to frame an executive order as to some of the wave length dispositions contemplated. (This article appeared in the St. Petersburg Times on March 22, 1923) — Are to Revise Wavelenghts. — Decision Made Saturday at End of Second Annual Radio Session. — WASHINGTON, Mar. 26--Recommendations for a revision of wave lengths in the ether for wireless use were completed Saturday by the second annual radio conference. Experts and government officials joined unanimously in suggesting to Secretary Hoover that President Harding be asked to open up to the public the wave bank hitherto reserved for military and governmental service and that broadcasting stations hereafter be given individual wave lengths on which they may continue their services with less interference to other users. Present powers of the commerce department, the conference decided, are sufficient to establish and enforce the new regulations, and thus bring order to the radio world. "Previously, all broadcasting was concentrated on three wave lengths," the official summary of the conference recommendations explained, "360, 300 and 485 metres. Now a new field extending from 222 to 545 metres can be created for the purpose. Within that field stations can be assigned individual wave lengths and divided into two classes: The higher power class "A" stations corresponding to the present class "B" stations can use the wave lengths between 288 meters and 545 meters, while lower powered stations "new class" "B" stations can use wave lengths from 222 (?) to [illegible]. This will enable the higher power stations distributed to 50 localities and comprehensively covering the United Sates to be within the reach of every listener. Suitable wave lengths are provided in the recommendations for the more than 500 existing lower power stations. "The report urges that the field of amateur activity be extended by plotting a band extending from 150 meters to 222 meters in place of the waves up to 200 meters now used. The band from 200 to 222 meters can be reserved for high grade continuous wave telegraph transmitting stations operating under special license. Technical and [illegible] school licenses can also occupy this band. The report [illegible] spark-amateur radio telegraphs to the band 175 to 200 metres. "It also includes the provision [illegible] ship using 540 metre waves to keep silent between 1 and 7 p.m. and as soon as possible, readjust their equipment for transmission to wave lengths above 600 metres. Provision is made in the recommendations for a new field of ship telephone service, enabling persons on shore to talk to those aboard ship. This can be carried out on waves far above broadcasting waves so that no interference can result.". (This article appeared in the St. Petersburg Times on March 27, 1923)
