                       TITLE 47--TELECOMMUNICATION
                    Subpart C--Intentional Radiators
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.
