Sec.  15.239   Operation in the band 88–108 MHz.

   (a) 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 frequency range of 88–108 MHz.

   (b) The field strength of any emissions within the permitted 200 kHz band
   shall not exceed 250 microvolts/meter at 3 meters. The emission limit in
   this paragraph is based on measurement instrumentation employing an average
   detector. The provisions in  Sec. 15.35 for limiting peak emissions apply.

   (c) The field strength of any emissions radiated on any frequency outside of
   the specified 200 kHz band shall not exceed the general radiated emission
   limits in  Sec. 15.209.

   (d) A custom built telemetry intentional radiator operating in the frequency
   band 88–108 MHz and used for experimentation by an educational institute
   need not be certified provided the device complies with the standards in
   this part and the educational institution notifies the Engineer in Charge of
   the local FCC office, in writing, in advance of operation, providing the
   following information:

   (1) The dates and places where the device will be operated;

   (2) The purpose for which the device will be used;

   (3) A description of the device, including the operating frequency, RF power
   output, and antenna; and,

   (4) A statement that the device complies with the technical provisions of
   this part.
