§ 90.463   Transmitter control points.

   (a) A control operator is required to be stationed at the operating position
   of a transmitter control point. A control operator is any person designated
   by the licensee to exercise supervision and control over the operation and
   use of the licensee's facilities. The control operator may be the licensee;
   or an employee of the licensee; or the agent of the licensee, appointed by
   the licensee to act as the control operator; or a third-party contractor,
   engaged by the licensee to serve as the control operator: Provided, however,
   In no case, through appointment or designation of any person to serve as
   control  operator,  may  the  licensee  delegate any of the duties and
   responsibilities the licensee may have in his capacity as licensee.

   (b) Each station or licensed system of communication shall normally have a
   control point, or control points, at which the control operator or operators
   are stationed and at or from which the licensee may exercise supervision and
   control over the authorized facilities, as required by the provisions of
   § 90.461. Provided, however, Control point requirements may vary from one
   system to another, depending upon the nature of the radio operation; the way
   and by whom the facilities are employed; and other factors, as set out in
   other rule sections under this subpart.

   (c) A transmitter control point may be located at a fixed position in a
   system of communication at or from which the control operator exercises
   supervision  and  control  over  the operation and use of the licensed
   facilities. Each fixed transmitter control point shall have equipment and
   facilities to permit the control operator:

   (1) To determine when the transmitter or transmitters controlled are either
   radiating “RF” energy, or when the transmitter circuits have been placed in
   a condition to produce such radiation. This may be accomplished either
   through  the  use of a carrier operated device which provides a visual
   indication when the transmitter(s) are radiating or a pilot lamp or meter
   which provides a visual indication when the transmitter circuits have been
   placed  in  a  condition  to produce radiation. Further, where a local
   transmitter is used to activate a remote transmitter or transmitters in the
   licensee's system of communication, a single pilot lamp or meter may be
   employed  to  indicate the activation of both the local and the remote
   transmitter(s).

   (2) To turn the carrier of the transmitter on and off at will, or to close
   the system down completely, when circumstances warrant such action.

   (d) The licensee's transmitting facilities may be operated from dispatch
   points, the fixed control point shall have equipment to permit the control
   operator  to  either  disconnect  the dispatch point circuits from the
   transmitter(s) or to render the transmitter(s) inoperative from any dispatch
   point being supervised.

   (e) Where the system is interconnected with public communication facilities,
   as provided at § § 90.477 through 90.483, and where those rules so require,
   the fixed control point shall be equipped to permit the control operator:

   (1) To monitor co-channel facilities of other licensees sharing an assigned
   channel or channels with the licensee in the licensee's area of operation;
   and,

   (2) To terminate any transmission(s) or communication(s) between points in
   the public communications system and the private communications system.

   (f) In urban areas, the location of fixed transmitter control points will be
   specified, “same as transmitter,” unless the control point is at a street
   address which is different from that of the transmitter(s) controlled. In
   rural areas, the location of fixed control points will be specified, “same
   as transmitter,” unless the control point is more than 152.5 m (500 ft) from
   the transmitter(s) controlled. In the latter case, the approximate location
   of the control point will be specified in distance and direction from the
   transmitter(s) controlled in terms of distance and geographical quadrant,
   respectively. It would be assumed that the location of a fixed control point
   is the same as the location of the transmitter(s) controlled, unless the
   applicant  includes  a  request  for a different location described in
   appropriate terms as indicated herein.

   (g) [Reserved]

   (h) Mobile transmitters shall be assumed to be under the immediate control
   of the mobile operator; provided, however, overall supervision and control
   of the operation and use of a communication system may be the responsibility
   of a fixed control point operator. In general, mobile transmitters shall be
   equipped to permit the operator to determine when they are radiating “RF”
   energy or when the transmitter circuits have been placed in a condition to
   produce such radiation. This may be accomplished either through the use of a
   carrier operated device or of a pilot lamp or meter which will provide a
   visual indication when the transmitter is radiating or has been placed in a
   condition to produce radiation provided, however, that hand-carried or
   pack-carried transmitters and transmitters installed on motorcycles need not
   be so equipped.
