Feb., 1945 EXCERPTS FROM FCC REPORT 133
tion, experimentation with intra and inter-city relay of theater television programs may be authorized in the following bands of frequencies, namely, 1900-2300, 3900-4550, 5750-7050, 10,500-13,000, 16,000-18,000, and 26,000-30,000 megacycles, as discussed in section 19 of this part."
SECTION 19— RELAY SYSTEMS INTRODUCTORY
"The allocation of frequencies for use by relays presently operated as links in fixed public point-to-point services and in connection with such radio services as police, forestry, and the like have already been considered and dealt with under the respective services. The types of stations here considered in connection with the allocation of specific frequencies for relay operations are the following:
(1) those which are designed to be operated as common carrier systems;
(2} those which are used for relaying programs in connection with individual
broadcast services and in connection with certain point-to-point radio
services not open to public correspondence.
"The Commission has promulgated no specific rules and regulations governing the operation of relay systems such as those dealt with in this section and no frequencies are now specifically allocated for that purpose. Authorizations for the stations now operating as relay stations of the types here considered have been granted on an experimental basis only. Proposals made at the hearing involve setting aside substantial portions of the radio spectrum for the exclusive use of relay systems. They are discussed more fully below.
"All the relay stations now authorized, with the possible exception of a few common carrier radio links and radio control and keying circuits, are operating, or have been authorized to operate within the frequency bands which the Commission now proposes to allocate for such purposes. Due to the fact that much experimental and developmental work remains to be done, any conclusions at this time with respect to the most desirable position in the spectrum for relay operations would appear to be premature. It is for this reason that the Commission is of the opinion that it is essential that all radio relay operations be presently authorized on an experimental basis only.
