You are correct, it was a a partial quote.
It is part 90 section 20
(5) A Police licensee may use, without special authorization from
the Commission, any mobile service frequency between 40 and 952 MHz,
listed in paragraph (c)(3) of this section, for communications in
connection with physical surveillance, stakeouts, raids, and other such
activities. Such use shall be on a secondary basis to operations of
licensees regularly authorized on the assigned frequencies. The maximum
output power that may be used for such communications is 2 watts.
Transmitters, operating under this provision of the rules, shall be
exempted from the station identification requirements of Sec. 90.425.
Use of frequencies not designated by a ``PP'' in the coordinator column
of the frequency table in paragraph (c)(3) of this section, is
conditional on the approval of the coordinator corresponding to each
frequency. Spread spectrum transmitters may be operated on Public Safety
Pool frequencies between 37 and 952 MHz, providing that they are
certificated by the Commission under the provisions of Sec. 2.803 of
this chapter and Sec. 90.203, and meet the following conditions:
(i) Frequency hopping transmitters can be operated, with a maximum
output power of 2 watts, on any Public Safety Pool frequency between 37
and 952 MHz listed in paragraph (c)(3) of this section. At least 20
hopping frequencies shall be used and the average time of occupancy on
any frequency shall not be greater than \1/10\ second in every 2
seconds;
(ii) Use of spread spectrum transmitters under paragraph (f)(4) of
this section is subject to approval by the applicable frequency
coordinator of the radio services of the district in which the license
and equipment are to be used; and
(iii) The use of direct sequence spread spectrum equipment is also
permitted. Equipment must meet the technical standards of Sec. 15.247 of
this chapter.
(6) In addition to the frequencies assigned for mobile service
operation, one base station frequency above 152 MHz may be assigned as a
common frequency to all licensees in a particular area to permit
intersystem communication between base stations or mobile stations or
both. This frequency use will not be authorized in any area where all
available frequencies are required for independent systems.
(7) A licensee may use, without a specific authorization from the
Commission, transmitters on the frequencies indicated below in
connection with wildlife tracking and/or telemetry and in connection
with official forestry-conservation activities, provided that such use
shall be on a secondary basis and shall not cause harmful interference
to services of other licensees operating on regularly assigned
frequencies. The provisions of Sec. 90.203, Sec. 90.425, and Sec. 90.429
shall not apply to transmitters complying with this paragraph. To be
eligible for operations in this manner, the transmitter must comply with
all of the following requirements.
(i) The carrier frequency shall be within the bands listed below.
The carrier frequency must be maintained
[[Page 279]]
within 0.005 percent of the frequency of operation.
Use on assigned channel center frequencies is not required.

(ii) The emitted signal shall be non-voice modulation (A1D, A2D,
F1D, or F2D emission).
(iii) The maximum occupied bandwidth, containing 99 percent of the
radiated power, shall not exceed 0.25 kHz.
(iv) The transmitter output power shall not exceed a mean power of 5
mW nor shall any peak exceed 100 mW peak power, as measured into a
permanently attached antenna; or if the transmitter and antenna
combination are contained in a sealed unit, the field strength of the
fundamental signal of the transmitter and antenna combination shall not
exceed 0.29 V/m mean or 1.28 V/m peak when measured at a distance of 3
meters.
(v) The requirements of Sec. 90.175 regarding frequency coordination
apply.
(
An additional frequency may be assigned for paging operations
from those frequencies available under paragraph (d)(13) of this
section.
(9) The frequency 155.340 MHz may be assigned as an additional
frequency when it is designated as a mutual assistance frequency as
provided in paragraph (d)(40) of this section.
(10) Additional frequencies may be assigned for fixed station
operations.
(11) The assignment of an additional frequency or frequencies may be
authorized notwithstanding this limitation for common, intra-county,
intra-fire-district, or intrastate fire coordination operations. The
frequency or frequencies requested must be in accordance with a
frequency utilization plan, for the area involved, on file with the
Commission.
