§ 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.
