§ 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.
