§  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 § 15.35
   for limiting peak emissions apply.
