Sec.  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 of any emissions 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 1500 microvolts/meter at 3 meters. The emission limits in
   this paragraph are based on measurement instrumentation employing an average
   detector. The provisions in  Sec. 15.35 for limiting peak emissions apply.
