338 McCoy AND WARNER October
In its final report of May 25, 1945, in the general allocation hearing, the FCC allocated certain frequency bands to theater television on a shared basis with other services for experimental use only. It made no exclusive allocation to theater television. The bands on which experimental theater television were permitted included the 480 to 920megacycle band (on which experimentation with multiple-addressee systems was permitted), subject to the understanding "that the band 480 to 920 megacycles will be used primarily for television broadcasting to the public, with higher frequencies being more properly utilized by theater television and relay operation." In addition, the following bands, allocated to the Fixed and Mobile service were made * 'available for theater television experimental use, including multiple-addressee purposes if the need for such use can be established": 1325 to 1375; 1750 to 2100; 2450 to 2700; 3900 to 4400; 5650 to 7050; 10,500 to 13,000; 16,000 to 18,000; and 26,000 to 30,000 megacycles. The FCC's final report thus opened the door for theater television experimentation in a large portion of the radio spectrum. As a practical matter, however, even in 1949 equipment is available for radio relay only on the frequencies up to the 7000-megacycle band, and equipment is actively being developed in the 10,000 to 13,000-megacycle band. Development of equipment for use in the 16,000 and 26,000megacycle bands must await the future.
The 1945 allocations in the spectrum between 1000 and 13,000 megacycles did not remain "final" for long. In November, 1945, the 4000 to 4200-megacycle band was allocated to Air Navigation Aids. In July, 1946, the FCC proposed an extensive reallocation of frequencies in the 1000 to 13,000-megacycle band. A hearing was held on this proposal, as amended October 22, 1946, and Mr. Larsen again testified on behalf of theater television and the SMPE on February 4, 1947. He took the position that theater television should be classified by the FCC as a " common-carrier" service, entitled to use the frequencies allocated to "Common-Carrier Fixed Circuits." If this classification was not made by the FCC, Mr. Larsen objected to the proposal of the FCC that television pickup and STL stations "will be licensed only to licensees of television broadcast stations and to common carriers." Finally, Mr. Larsen objected to the failure of the FCC to include in its proposal frequencies for intercity television relay, which the FCC stated could not be accommodated in the 1000to 13,000-megacycle band since there was not sufficient spectrum
