Sec.  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
    Sec. 90.265(b).
