  Sec.  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 log[10](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.
