Sec.  87.143   Transmitter control requirements.

   (a) Each transmitter must be installed so that it is not accessible to, or
   capable of being operated by persons other than those authorized by the
   licensee.

   (b) Each station must be provided with a control point at the location of
   the transmitting equipment, unless otherwise specifically authorized. Except
   for aeronautical enroute stations governed by paragraph (e) of this section,
   a control point is the location at which the radio operator is stationed. It
   is the position at which the transmitter(s) can immediately be turned off.

   (c)  Applicants for additional control points at aeronautical advisory
   (unicom) stations must specify the location of each proposed control point.

   (d) Except for aeronautical enroute stations governed by paragraph (f) of
   this  section,  the  control  point must have the following facilities
   installed:

   (1) A device that indicates when the transmitter is radiating or when the
   transmitter control circuits have been switched on. This requirement does
   not apply to aircraft stations;

   (2) Aurally monitoring of all transmissions originating at dispatch points;

   (3) A way to disconnect dispatch points from the transmitter; and

   (4) A way to turn off the transmitter.

   (e) A dispatch point is an operating position subordinate to the control
   point. Dispatch points may be installed without authorization from the
   Commission, and dispatch point operators are not required to be licensed.

   (f)  In  the  aeronautical  enroute  service, the control point for an
   automatically controlled enroute station is the computer facility which
   controls  the transmitter. Any computer controlled transmitter must be
   equipped  to  automatically  shut  down  after 3 minutes of continuous
   transmission of an unmodulated carrier.
