    which the station is situated followed by the letter Y and one
    or more identification letters—e.g., 1YA, 3YKG.

34. Any licensee or operator who impersonates any other licensee or
    operator, or who improperly uses the call signal of another radio station,
    commits an offence against these regulations.

DECLARATION OF SECRECY.

35. Every licensee (other than an association or corporation) and every
    operator shall execute a declaration of secrecy to the effect that he will
    not divulge to any unauthorized person any information whatsoever relating
    to public correspondence that may come to his knowledge; and that he
    will, by every means in his power, seek to preserve the secrecy of the same.
    Such licensee or operator shall not commit to writing any public corre-
    spondence that may come to his knowledge while exercising the powers
    conferred upon him by the license. In the case of societies, institutes, and
    similar bodies, all members of the body having access to the apparatus
    shall execute the declaration of secrecy, and special care shall be taken
    to ensure that all the conditions of the license, particularly those relating
    to secrecy of public correspondence, are strictly observed.

CONTROL OF RADIO STATION IN EMERGENCY.

36. If and whenever an emergency shall have arisen in which it is
    expedient in the public interest that His Majesty’s Government shall have
    control over the transmission of radio communications by the licensed
    apparatus, it shall be lawful for any officer of His Majesty’s Navy or
    Army, or for any other person authorized in that behalf by the Admiralty
    or by the Minister, to take possession of, or to dismantle, or to cause the
    licensed apparatus or any part thereof to be taken possession of or to be
    dismantled in the name and on behalf of His Majesty, and to be used where
    such use may be deemed necessary for His Majesty’s service, and, subject
    thereto, for such ordinary services as the said officer or person may deem fit;
    and in that event any person authorized by the said officer or person may
    enter any radio station in which any such apparatus is installed and take
    possession of or dismantle the said apparatus and use the same as aforesaid.

INSPECTION DURING CURRENCY OF LICENSE.

37. The radio station must be open to inspection at all times by a District
    Radio Inspector, and every reasonable facility given for ascertaining the
    condition of the station and whether the regulations are being strictly
    complied with.
38. The license of the radio station and the operator’s certificate shall
    at all times be exhibited in a prominent place at the radio station.

NATURE OF RADIO COMMUNICATIONS.

39. A radio station licensed under these regulations 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 a loss of
    revenue to the Post and Telegraph Department.
40. The licensee or the operator shall not transmit any radio com-
    munication of a seditious, profane, obscene, libellous, or offensive nature.
41. The licensee or the operator shall not transmit any radio com-
    munication of a false or misleading character, and, in particular, shall not
    transmit any false S.O.S. signal.

TRANSMITTING STATIONS TO BE EQUIPPED FOR RECEPTION.

42. An amateur, experimental, or broadcasting station shall be equipped
    for reception as well as for transmission, and shall observe the prescribed
    conditions relating to the keeping of a watch for the interference warning
    signal, AAAAQRM; provided that this requirement may be waived by
    the Minister in the case of a broadcasting station communication with
    which can be conveniently obtained by an adjacent coast station by means
    of a Government telephone-exchange connection.
