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 anaverage 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.
