Sec. 4.74 Reports by Class II Stations Quarterly reports on forms prescribed by the Commission shall be made by Class II television broadcast stations of their charges and costs as well as of other pertinent information which may be of assistance to the Commission in evaluating the economic feas¬ ibility of television broadcasting as a regular service to the public on a commercial basis. Sec. 4.75 Announcements At the time station identification announcements are made, there shall be added the following: “This is a special television broadcast made by authority of the Federal Communications Commission for experimental purposes.” Sec. 4.76 Scope of Experimentation, Limitations and Restrictions (a) Class I stations shall operate to conduct research and ex¬ perimentation for the development of the television broadcast art in its technical phases but shall not operate to render a regularly scheduled television broadcast service to the public. (b) No Class I station shall operate when objectionable inter¬ ference would be caused by such operation to the regularly sched¬ uled broadcast service of a Class II station. (c) Class II stations shall operate to conduct television broadcast research and experimentation for the development of the art in its program phases and in connection therewith may carry out experiments with respect to power and antenna requirements for a satisfactory service to the public. (d) Class II stations shall make all equipment changes neces¬ sary for rendering such external transmitter performance as the Commission may at any time require. * This provision modifies Section 4.4(d) in so far as that Section applies to Class It television broadcast stations. (e) Class II stations shall maintain a minimum scheduled pro¬ gram service of ten hours per week throughout the license periorl. Sec. 4.77. Frequency assignment. (a) The following groups of channels are allocated for assign¬ ment to television broadcast stations licensed experimentally: Group A Channel #1 44,000 50,000 kc. 2 50.000 56,000 3 66,000 72,000 4 78.000 84,000 5 84,000 90,000 6 96.000-102.000 7 102,000-108.000 Group B Channel #8 156,000-162.000 kc. 9 162,000-168,000 10 180.000-186.000 11 186.000-192,000 12 204,000-210,000 13 210.000-216,000 14 234,000-240,000 15 240,000-246,000 16 258,000-264,000 17 264,000-270,000 18 282,000-288,000 19 288,000-294,000 Group C .Any 6000 kc. band above 300.000 kc. excluding band 400,000 to 410,000 kc.

Both aural and visual carriers with side bands for modulation arc authorized for both Class I and Class II stations but no emission shall result outside the authorized channel. The assignment of a channel to a Class II television broadcast station does not pre¬ clude the assignment of that channel for use by Class I stations, but such a Class II television station shall have priority for the use of the channel for its scheduled program service. Licenses for both a Class I and a Class II station may be issued to a single licensee only upon a showing that the development of the television art will be assisted thereby, particularly where authority to operate on channels in Group B and C is requested for the Class I oper¬ ations.

No mobile or portable station will be licensed for the purpose of transmitting television programs to the public directly. (d) For the present no Class II television broadcast station will be assigned a channel for time sharing operation.'^ Sec. 4.78 Pou'er.
