§ 15.223   Operation in the band 1.705-10 MHz.

   (a) The field strength of any emission within the band 1.705-10.0 MHz
   shall not exceed 100 microvolts/meter at a distance of 30 meters.
   However, if the bandwidth of the emission is less than 10% of the
   center frequency, the field strength shall not exceed 15
   microvolts/meter or (the bandwidth of the device in kHz) divided by
   (the center frequency of the device in MHz) microvolts/meter at a
   distance of 30 meters, whichever is the higher level. For the purposes
   of this section, bandwidth is determined at the points 6 dB down from
   the modulated carrier. The emission limits in this paragraph are based
   on measurement instrumentation employing an average detector. The
   provisions in § 15.35(b) for limiting peak emissions apply.

   (b) The field strength of emissions outside of the band 1.705-10.0 MHz
   shall not exceed the general radiated emission limits in § 15.209.
