§ 101.131 Transmitter construction and installation.
(a) The equipment at the operating and transmitting positions must be
so installed and protected that it is not accessible to, or capable of
being operated by, persons other than those duly authorized by the
licensee.
(b) In any case where the maximum modulating frequency of a transmitter
is prescribed by the Commission, the transmitter must be equipped with
a low-pass or band-pass modulation filter of suitable performance
characteristics. In those cases where a modulation limiter is employed,
the modulation filter must be installed between the transmitter stage
in which limiting is effected and the modulated stage of the
transmitter.
(c) Each transmitter employed in these services must be equipped with
an appropriately labeled pilot lamp or meter which will provide
continuous visual indication at the transmitter when its control
circuits have been placed in a condition to activate the transmitter.
In addition, facilities must be provided at each transmitter to permit
the transmitter to be turned on and off independently of any remote
control circuits associated therewith.
(d) At each transmitter control point the following facilities must be
installed:
(1) A carrier operated device which will provide continuous visual
indication when the transmitter is radiating, or, in lieu thereof, a
pilot lamp or meter which will provide continuous visual indication
when the transmitter control circuits have been placed in a condition
to activate the transmitter; and
(2) Facilities which will permit the operator to turn transmitter
carrier on and off at will.
(e) Transmitter control circuits from any control point must be so
installed that grounding or shorting any line in the control circuit
will not cause the transmitter to radiate: provided, however, That this
provision will not be applicable to control circuits of stations which
normally operate with continuous radiation or to control circuits which
are under the effective operational control of responsible operating
personnel 24 hours per day.
