§ 90.249 Control stations.
Control stations associated with land mobile stations under this part
shall be authorized to operate subject to the following:
(a) Frequencies for control stations. (1) Control stations may be
authorized to operate on frequencies available for use by operational
(2) A control station associated with mobile relay station(s) may, at
the option of the applicant, be assigned the frequency of the
associated mobile station. In the Industrial/Business Pool, on
frequencies designated with an “LR” in the coordinator column of the
frequency table in § 90.35(b)(3), such a control station may be assigned
any mobile service station frequency available for assignment to mobile
stations. Such operation is on a secondary basis to use of the
frequency for regular mobile service communications.
(3) Control and fixed stations in the Public Safety Pool may be
authorized on a temporary basis to operate on frequencies available for
base and mobile stations between 152 and 450 MHz, where there is an
adequate showing that such operations cannot be conducted on
frequencies allocated for assignment to operational fixed stations.
Such operation will not be authorized initially or renewed for periods
in excess of one year. Any such authorization shall be subject to
immediate termination if harmful interference is caused to stations in
the mobile service, or if the particular frequency is required for
mobile service operations in the area concerned.
(c) A base station which is used intermittently as a control station
for one or more associated mobile relay stations of the same licensee
shall operate only on the mobile service frequency assigned to the
associated mobile relay station when operating as a base station and on
the mobile service frequency assigned to the associated mobile station
when operating as a control station. Authority for such dual
classification and use must be shown on the station authorization. When
operating as a control station, the licensee must meet all control
station requirements. In the Industrial/Business Pool, on frequencies
designated with an “LR” in the coordinator column of the frequency
table in § 90.35(b)(3), base stations used intermittently as control
stations shall operate only on a mobile service frequency which is
available for assignment to base stations.
