§ 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.
