Harmonic & Spurious
Radiation:
Any emission appearing on a frequency removed from the carrier by
between 120 kHz and 240 kHz inclusive is attenuated at least 25 dB below the level
of the unmodulated carrier.
Any emission appearing on a frequency removed from the carrier by more than 240
kHz and up to and including 600 kHz is attenuated at least 35 dB below the level of
the unmodulated carrier.
Any emission appearing on a frequency removed from the carrier by more than 600
kHz is attenuated at least 80 dB below the level of the unmodulated carrier.
