  Sec.  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.
