  §  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
   modulation (F3).

   (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.
