                    Subpart D_Technical Requirements

 

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.
