essential communications related to training and maintenance of an
efficient organization. In addition to base and mobile stations, this
frequency may be assigned to fixed stations on a secondary basis to base
or mobile stations. Upon a showing of need, the use of a second
frequency in the band 2505-3500 kHz may be made available to these
organizations through appropriate arrangements with Government agencies
for restricted area use on a shared basis with maximum power output,
emission, and hours of operation determined on the basis of the
technical conditions involved in using the selected frequency in the
particular area.
(2) This frequency is shared with the Police Radio Service.
(3) The maximum output power of any transmitter authorized to
operate on this frequency shall not exceed 2 watts.
(4) Subpart T contains rules for assignment of frequencies in the
220-222 MHz band.
(5) This frequency is not available for assignment in this service
in Puerto Rico or the Virgin Islands.
(6) Assignment and use of frequencies in the band 72-76 MHz are

(14) Subpart L contains rules for assignment of frequencies in the
470-512 MHz band.
(15) Subpart S contains rules for assignment of frequencies in the
806-824 MHz and 851-869 MHz bands.
(16) Assignment of frequencies above 928 MHz for operational-fixed
stations is governed by part 94 of this chapter.
(17) This frequency band is available to stations in this service
subject to the provisions of Sec. 90.259.
(18) Available only on a shared basis with stations in other
services, and subject to no protection from interference due to the
operation of industrial, scientific, or medical (ISM) devices. In the
2483.5-2500 MHz band, no applications for new stations or modification
to existing stations to increase the number of transmitters will be
accepted. Existing licensees as of July 25, 1985, or on a subsequent
date following as a result of submitting an application for license on
or before July 25, 1985, are grandfathered and their operation is co-
primary with the Radiodetermination Satellite Service.
(19) Use of this frequency is limited to stations located at least
120.7 km (75 miles) from the center of any urbanized area of 200,000 or
more population (U.S. Census of Population 1970). Operation is on a
secondary basis to that of the Power Radio Service.
(20) For FM transmitters, the sum of the highest modulating
frequency in Hertz and the amount of the frequency deviation or swing in
Hertz may not exceed 2800 Hz and the maximum deviation may not exceed
2.5 kHz. For AM transmitters, the highest modulation frequency may not
exceed 2000 Hz. The carrier frequency must be maintained within .0005
percent of the center of the frequency band, and the authorized
bandwidth may not exceed 6 kHz.
(21) This frequency is available on a shared basis with the Power,
Petroleum, Forest Products, Special Industrial, Business, and
Manufacturers Radio Services for remote control and telemetry
operations.
(22) Operational fixed stations must employ directional antennas
having a front-to-back ratio of at least 20 dB. Omnidirectional antennas
