§ 90.217 Exemption from technical standards.
Except as noted herein, transmitters used at stations licensed below
800 MHz on any frequency listed in subparts B and C of this part or
licensed on a business category channel above 800 MHz which have an
output power not exceeding 120 milliwatts are exempt from the technical
requirements set out in this subpart, but must instead comply with the
following:
(a) For equipment designed to operate with a 25 kHz channel bandwidth,
the sum of the bandwidth occupied by the emitted signal plus the
bandwidth required for frequency stability shall be adjusted so that
any emission appearing on a frequency 40 kHz or more removed from the
assigned frequency is attenuated at least 30 dB below the unmodulated
carrier.
(b) For equipment designed to operate with a 12.5 kHz channel
bandwidth, the sum of the bandwidth occupied by the emitted signal plus
the bandwidth required for frequency stability shall be adjusted so
that any emission appearing on a frequency 25 kHz or more removed from
the assigned frequency is attenuated at least 30 dB below the
unmodulated carrier.
(c) For equipment designed to operate with a 6.25 kHz channel
bandwidth, the sum of the bandwidth occupied by the emitted signal plus
the bandwidth required for frequency stability shall be adjusted so
that any emission appearing on a frequency 12.5 kHz or more removed
from the assigned frequency is attenuated at least 30 dB below the
unmodulated carrier.
(d) Transmitters may be operated in the continuous carrier transmit
mode.
(e) Transmitters used for wireless microphone operations and operating
on frequencies allocated for Federal use must comply with the
requirements of § 90.265(b).
