  §  90.669   Emission limits.

   (a) On any frequency in an MTA licensee's spectrum block that is
   adjacent to a non-MTA frequency, the power of any emission shall be
   attenuated below the transmitter power (P) by at least 43 plus 10
   log10(P) decibels or 80 decibels, whichever is the lesser attenuation.

   Note: The measurements of emission power can be expressed in peak or
   average values, provided they are expressed in the same parameters as
   the transmitter power.

   (b) When an emission outside of the authorized bandwidth causes harmful
   interference, the Commission may, at its discretion, require greater
   attenuation than specified in this section.
