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 
log10(P) decibels

[[Page 570]]

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.
