only by a person holding an amateur operator's certificate endorsed to
authorize the operation of a broadcasting station : Provided that the
Minister may waive the requirements of the Amateur Radio Regulations,
1925; in respect of Morse operating, and substitute therefor a requirement
that a candidate for an amateur operator's certificate with an endorsement
as hereinbefore provided shall possess an adequate knowledge of the theory
of radio-telephony and of the adjustment and working of the apparatus
used for radio-telephony.

(2.) The Minister may permit of the operation of a broadcasting station
by a person holding a certificate of a class higher than the endorsed amateur
operator's certificate prescribed in this regulation.

    personally supervise the operation of the apparatus in a broadcasting station
    during the whole time radio communications are being transmitted.

22. Each broadcasting station shall be allotted an official call signal
    by which the station shall be identified, and which is to be used in the
    manner prescribed in Regulation 30 hereof whenever a radio communication
    is transmitted from the said broadcasting station.

23. The licensee shall maintain at each broadcasting station a broad-
    casting service of a minimum duration of twelve hours weekly (Sundays
    not included), and the Minister shall determine the daily duration of the
    programme transmitted by each such broadcasting station : Provided that
    the Minister may approve in writing of any broadcasting station remaining
    silent for one day in each week (Sunday not included).

24. The licensee shall ensure that sufficient spare parts and apparatus
    are always readily available at each broadcasting station to enable the
    programmes to be transmitted regularly and reliably.

    charge to the Government, as part of the regular programme of any
    broadcasting station, any announcements by the New Zealand Government
    or by any Department thereof.

26. A broadcasting station shall not be used in any way to compete
    with Government communication services, and shall not transmit or receive
    radio communications the transmission or reception of which is calculated,
    in the judgment of the Minister, to cause loss of revenue to the Post and
    Telegraph Department.

27. The licensee shall not conduct point-to-point communication, but
    shall transmit from broadcasting stations radio communications of general
    public interest only.

28. Subject to the provisions of Regulation 29 hereof, neither direct
    nor indirect advertising shall be undertaken by the licensee from any broad-
    casting station, unless specially authorized by the Minister.

29. (1.) A broadcasting station shall not be used for the dissemination
    of propaganda of a controversial nature, but shall be restricted to matter
    of an educative, informational, or entertaining character, such as news,
    lectures, useful information, religious services, musical or elocutionary
    entertainment, and other items of general public interest as may be
    approved by the Minister from time to time.

(2.) The licensee shall supervise with all reasonable care, to the satis-
faction of the Minister, the matter broadcasted, and shall carefully select
the matter to be broadcasted in order to give effect to the requirements of
this regulation.

    the operator or announcer shall announce the call signal of the broadcasting
    station ; and in addition thereto may announce the full name and address
    of the station, and make brief remarks relevant to the matter about to be
    broadcasted.

31. Every person who impersonates any other radio station or any
    other person, or who improperly uses the call signal of another radio
    station, commits an offence against these regulations.

32. The licensee shall not permit the transmission of any radio com-
    munication of a seditious, profane, obscene, libellous, or offensive nature.

33. The licensee shall not permit the transmission of any radio com-
    munication of a false or misleading character, and in particular shall not
    transmit any false international distress signal or any other false signal of
    similar import.

34. The Minister may permit the use of mechanically operated musical
    instruments in broadcasting stations : Provided that the use of such
    instruments is strictly limited to a comparatively small part of the time
    occupied by the station in transmitting programmes.
