Sec. 78.51  Remote control operation.

    (a) A CARS station may be operated by remote control: Provided, That 
such operation is conducted in accordance with the conditions listed 
below: And provided further, That the Commission, in Washington, DC, is 
notified at least 10 days prior to the beginning of such operation and 
that such notification is accompanied by a detailed description showing 
the manner of compliance with the following conditions:
    (1) The transmitter and associated control system shall be installed 
and protected in a manner designed to prevent tampering or operation by 
unauthorized persons.
    (2) An operator shall be on duty at the remote control position and 
in actual charge thereof at all times when the station is in operation.
    (3) Facilities shall be provided at the control position which will 
permit the operator to turn the transmitter on and off at will. The 
control position shall also be equipped with suitable devices for 
observing the overall characteristics of the transmissions and a carrier 
operated device which will give a continuous visual indication whenever 
the transmitting antenna is radiating a signal. The transmitting 
apparatus shall be inspected as often as may be necessary to insure 
proper operation.
    (4) The control circuits shall be so designed and installed that 
short circuits, open circuits, other line faults, or any other cause 
which would result in loss of control of the transmitter will 
automatically cause the transmitter to cease radiating.
    (b) An application for authority to construct a new station or to 
make changes in the facilities of an existing station and which proposes 
operation by remote control shall include an adequate showing of the 
manner of compliance with the requirements of this section.
    (c) The Commission may notify the licensee not to commence remote 
control operation, or to cancel, suspend, or change the date of the 
beginning of such operation as and when such action may appear to be in 
the public interest, convenience, or necessity.
