126. (1) The licensee shall take due precaution to preclude over-loading or distortion in any stage of the apparatus, and in this connection some visual indication of modulation level shall be provided, together with suitable means of control.

(2) In the case of stations having an anode power exceeding 300 watts a monitoring attendant shall be in constant attendance for the control of such apparatus.

127. (1) Except with the Minister’s approval, any studio or room housing the microphone apparatus shall be separate from the room containing the transmitting-apparatus.

(a) A practical knowledge of the adjustment and operation of typical broadcasting-station apparatus (including speech-input equipment, studio-control equipment, and radio-receivers), together with an elementary knowledge of the theory of electricity and magnetism. This will include tracing and clearing faults in the apparatus; altering the frequency (wave-length); testing and charging accumulators; maintenance of motor generators and other accessory apparatus; a knowledge of the functions of the various pieces of apparatus; and a knowledge of the care and adjustment necessary to maintain the apparatus in an efficient condition.

(b) Ability to transmit and receive clearly conversation by radio-telephone apparatus.

(c) A detailed knowledge of such of these regulations as relate to the design and operation of broadcasting-station apparatus.

(2) The fee for examination for a radio-broadcasting operator’s certificate shall be 5s.

(3) The fee payable in respect of a duplicate of a radio-broadcasting operator’s certificate shall be 5s. Such duplicate shall be issued only on production of satisfactory evidence that the original certificate has been lost or destroyed.

131. The holder of an operator’s certificate issued under the Broadcasting Regulations, 1925, may, on application, have such certificate exchanged, free of charge, for a radio-broadcasting operator’s certificate.

132. The examination for a technical certificate in broadcasting shall comprise (i) the examination described in paragraphs (a), (b), and (f) of clause (1) of Regulation 96 hereof (relating to the examination for a first-class radio-telegraph operator’s certificate): Provided that the examination described in clause (f) aforesaid shall be extended to include a practical examination in the operation and adjustment of typical broadcasting-station equipment; and (ii) an examination requiring a detailed knowledge of such of these regulations as relate to the design and operation of broadcasting-station equipment.
