§ 15.237   Operation in the bands 72.0-73.0 MHz, 74.6-74.8 MHz and 75.2-76.0
MHz.

   (a) The intentional radiator shall be restricted to use as an auditory
   assistance device.

   (b) Emissions from the intentional radiator shall be confined within a band
   200 kHz wide centered on the operating frequency. The 200 kHz band shall lie
   wholly within the above specified frequency ranges.

   (c) The field strength within the permitted 200 kHz band shall not exceed 80
   millivolts/meter at 3 meters. The field strength of any emissions radiated
   on any frequency outside of the specified 200 kHz band shall not exceed the
   general radiated emissions limits specified in § 15.209. The emission limits
   in this paragraph are based on measurement instrumentation employing an
   average detector. The provisions in § 15.35 for limiting peak emissions
   apply.
