`
`s 22.106 Emission limit.
`
`(a) For transmitters other than those employing digital modulation techniques, the mean power of emissions shall be attenuated
`below the mean output power of the transmitter in accordance with the following schedule:
`(1) On any frequency removed from the assigned frequency by more than 50 percent up to and including 100 percent of the
`authorized bandwidth: at least 25 decibels;
`(2) On any frequency removed from the assigned frequency by more than 100 percent up to and including 250 percent of the
`authorized bandwidth: at least 35 decibels;
`(3) On any frequency removed from the assigned frequency by more than 250 percent of the authorized bandwidth: At least
`43 plus 10 Log10 (mean output power in watts) decibels, or 80 decibels, whichever is the lesser attenuation.
`(b) For transmitters not equipped with an audio low pass filter required by the provisions of paragraphs (f) and (g) of s 22.508,
`and for those employing digital modulation techniques, the power of any emission shall be attenuated below the unmodulated
`carrier power (P) in accordance with the following schedule:
`(1) For those transmitters that operate in the frequency bands of 35.0 to 44.0 MHz, 72.0 to 73.0 MHz, 75.4 to 76.0 MHz or
`152.0 to 159.0 MHz,
`(i) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in kHz) of more
`than 5 kHz up to and including 10kHz: at least 83 Log10 (fd/5) decibels;
`(ii) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in KHz) of more
`than 10 KHz up to and including 250 percent of the authorized bandwidth: At least 29 Log10 fd2/11 decibels or 50 decibels,
`whichever is the lesser attenuation;
`(iii) On any frequency removed from the center of the authorized bandwidth by more than 250 percent of the authorized
`bandwidth: at least 43 plus 10 Log10 (output power in watts) 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 unmodulated transmitter carrier power.
`(2) For those transmitters that operate in the frequency bands 450.0 to 512.0 MHz, or 929.0 to 932.0 MHz,
`(i) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in kHz) of more
`than 5 kHz up to and including 10 kHz: at least 83 Log10 (fd/5) decibels:
`(ii) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in kHz) of more
`than 10 kHz up to and including 250 percent of the authorized bandwidth: at least 116 Log10 (fd/6.1) decibels or 50 plus 10
`Log10 (P) or 70 decibels, whichever is the lesser attenuation;
`(iii) On any frequency removed from the center of the authorized bandwidth by more than 250 percent of the authorized
`bandwidth: at least 43 plus 10 Log10 (output power in watts) decibels or 80 decibels, whichever is the lesser attentation.
`
`Note: The measurements of emission power can be expressed in peak or average values provided they are expressed in the
`same parameters as the unmodulated transmitter carrier power.
`(3) For those transmitters that operate in the frequency bands 932-932.5/941-941.5 MHz with a 12.5 kHz bandwidth,
`(i) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (f subd in kHz) of
`more than 2.5 kHz up to and including 6.25 kHz: At least 53 log sub 10 (f subd /2.5) decibels;

`
`(ii) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (f subd in kHz) of
`more than 6.25 kHz up to and including 9.5 kHz: At least 103 log subd 10 (f subd 10/3.9) decibels;
`(iii) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (f subd 10 in kHz)
`of more than 9.5 kHz up to and including 15 kHz: At least 157 log sub 10 (f subd /5.3) decibels;
`(iv) On any frequency removed from the center of the authorized bandwidth by a displacement frequency greater than 15 kHz:
`At least 50 plus 10 log sub 10 (P) or 70 decibels, whichever is the lesser attenuation.
`(4) For those transmitters that operate in the frequency bands 932-932.5/941-941.5 MHz with a bandwidth greater than 12.5
`kHz,
`(i) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (f subd in kHz) of
`more than 5 kHz up to and including 10 kHz: At least 83 log sub 10 (f subd /5) decibels;
`(ii) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (f subd in kHz) of
`more than 10 kHz up to and including 250 percent of the authorized bandwidth: At least 116 log sub 10 (f subd /6.1) decibels
`or 50 plus 10 log sub 10 (P) or 70 decibels, whichever is the lesser attenuation;
`(iii) On any frequency removed from the center of the authorized bandwidth by more than 250 percent of the authorized
`bandwidth: At least 43 plus 10 log sub 10 (output power in watts) decibels or 80 decibels, whichever is the lesser attenuation.
`(c) 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.
