§ 74.736 Emissions and bandwidth.
(a) The license of a low power TV, TV translator, or TV booster station
authorizes the transmission of the visual signal by amplitude
modulation (A5) and the accompanying aural signal by frequency
(b) Standard width television channels will be assigned and the
transmitting apparatus shall be operated so as to limit spurious
emissions to the lowest practicable value. Any emissions including
intermodulation products and radio frequency harmonics which are not
essential for the transmission of the desired picture and sound
information shall be considered to be spurious emissions.
(c) Any emissions appearing on frequencies more than 3 MHz above or
below the upper and lower edges, respectively, of the assigned channel
shall be attenuated no less than:
(1) 30 dB for transmitters rated at no more than 1 watt power output.
(2) 50 dB for transmitters rated at more than 1 watt power output.
(3) 60 dB for transmitters rated at more than 100 watts power output.
(d) Greater attenuation than that specified in paragraph (c) of this
section may be required if interference results from emissions outside
the assigned channel.
