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.
