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.
