effecting expeditious repairs to interruption of public communications
facilities where such interruptions have resulted in disabling
intercity circuits or service to a multiplicity of subscribers in a
general area. Stations authorized under this section may be used only
when no other means of communication is readily available, for the
transmission of messages relating to the safety of life and property
and messages which are necessary for the efficient restoration of the
public communication facilities which have been disrupted.
(xiii) Persons or entities engaged in the provision of basic or
advanced life support services on an ongoing basis are eligible to hold

also operate, subject to all of the foregoing conditions and on a
secondary basis, radio units at fixed locations and in emergency
vehicles that transmit on the frequency 24.10 GHz, both unmodulated
continuous wave radio signals and modulated FM digital signals for the
purpose of alerting motorists to hazardous driving conditions or the
presence of an emergency vehicle. Unattended and continuous operation
of such transmitters will be permitted.
(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 § 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 § 2.803 of this
chapter and § 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 § 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 § § 90.203, 90.425, and 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

frequency utilization plan, for the area involved, on file with the
Commission.
(g) Former public correspondence working channel in the maritime VHF
(156-162 MHz) band allocated for public safety use in 33 inland
Economic Areas. (1) We define service areas in the marine VHF (156-162
MHz) band by forty-two geographic areas called VHF Public Coast Service
Areas (VPCSAs). See § 80.371(c)(1)(ii) of this chapter (Public
correspondence frequencies). VPCSAs are based on, and composed of one
or more of, the U.S. Department of Commerce's 172 Economic Areas (EAs).
See 60 Fed Reg. 13114 (Mar. 10, 1995). You may inspect and copy maps of
the EAs and VPCSAs at the FCC Reference Center, Room CY A-257, 445 12th
St., SW., Washington, DC 20554. These maps and data are also available
on the FCC website at http://www.fcc.gov/oet/info/maps/areas/. We
number public correspondence channels in the maritime VHF (156-162 MHz)
band as channels 24 to 28 and channels 84 to 88. Each channel number
represents a channel pair. See § 80.371(c) of this chapter.
(2) In VHF Public Coast Service Areas (VPCSAs) 10-42, the duplex
channel pair 157.250 MHz/161.850 MHz (VHF Maritime Channel 25) is
allocated for public safety use by entities eligible for licensing
under paragraph (a) of this section, and is designated primarily for
the purpose of interoperability communications. See 47 CFR
80.371(c)(1)(ii) for the definitions of VPCSAs.
(i) The channel pair 157.250 MHz/161.850 MHz was formerly allocated and
assigned (under § 80.371(c) (1997) of this chapter) as a public
correspondence working channel in the maritime VHF 156-162 MHz band,
and was also shared (under former § 90.283 (1997) of this chapter) with
private land mobile stations, including grandfathered public safety
licensees. Thus, there are grandfathered licensees nationwide (maritime
and private land mobile radio stations, including by rule waiver)
operating on this channel both inside and outside of VPCSAs 10-42.
(ii) The channel pairs 157.225 MHz/161.825 MHz and 157.275 MHz/161.875
MHz were formerly allocated and assigned under this section as public
safety interoperability channels but were reallocated for assignment as
VHF public coast station channels under § 80.371(c) of this chapter.
Public safety operations licensed on these channels as of March 2, 2009
or licensed pursuant to an application filed prior to September 19,
2008, may remain authorized to operate on the channels on a primary
basis until March 2, 2024.
(3) All applicants and licensees under this paragraph must comply with
the relevant technical sections under this part unless otherwise stated
in this paragraph (g) of this section using the following standards and
procedures:
(i) Provide evidence of frequency coordination in accordance with
§ 90.175. Public safety coordinators except the Special Emergency
Coordinator are certified to coordinate applications for the channel
pair 157.250 MHz/161.850 MHz (i.e., letter symbol PX under paragraph
(c)(2) of this section).
(ii) Station power, as measured at the output terminals of the
transmitter, must not exceed 50 Watts for base stations and 20 Watts
for mobile stations, except in accordance with the provisions of
paragraph (g)(3)(vi) of this section. Antenna height (HAAT) must not
exceed 122 meters (400 feet) for base stations and 4.5 meters (15 feet)
for mobile stations, except in accordance with paragraph (g)(3)(vi) of
this section. Antenna height (HAAT) must not exceed 122 meters (400
feet) for base stations and 4.5 meters (15 feet) for mobile stations,
except in accordance with paragraph (g)(3)(vi) of this section. Such
base and mobile channels shall not be operated on board aircraft in
flight.
(iii) Frequency protection must be provided to other stations in
accordance with the following guidelines for each channel and for each
area and adjacent area:
(A) Protect coast stations licensed prior to July 6, 1998, by the
required separations shown in Table C below.
(B) Protect stations described in paragraph (g)(2)(i) of this section,
by frequency coordination in accordance § 90.175 of this part.
(C) Protect public safety stations granted under paragraph (g) of this
section by frequency coordination in accordance with § 90.175 of this
part.
(D) Where the Public safety designated channel is not a Public safety
designated channel in an adjacent VPCSA: Applicants shall engineer base
stations such that the maximum signal strength at the boundary of the
adjacent VPCSA does not exceed 5dBµV/m.
(iv) The following table, along with the antenna height (HAAT) and
power (ERP), must be used to determine the minimum separation required
between proposed base stations and co-channel public coast stations
licensed prior to July 6, 1998 under part 80 of this chapter.
Applicants whose exact ERP or HAAT are not reflected in the table must
use the next highest figure shown.

(v) In the event of interference, the Commission may require, without a
hearing, licensees of base stations authorized under this section that
are located within 241 kilometers (150 miles) of a co-channel public
coast, I/LT, or grandfathered public safety station licensed prior to
July 6, 1998, or an international border, to reduce power, decrease
antenna height, and/or install directional antennas.
Mobile stations must be operated only within radio range of their
associated base station.
(vi) Applicants seeking to be licensed for stations exceeding the
power/antenna height limits of the table in paragraph (g)(3)(iv) of
this section must request a waiver of that paragraph and must submit
with their application an interference analysis, based upon an
appropriate, generally-accepted terrain-based propagation model, that
shows that co-channel protected entities, described in paragraph
(g)(3)(iii) of this section, would receive the same or greater
interference protection than the relevant criteria outlined in
paragraph (g)(3)(iii) of this section.
(h) Spectrum leasing arrangements. Notwithstanding any other provisions
of this section to the contrary, licensees in the Public Safety Radio
Services (see part 90, subpart B) may enter into spectrum leasing
arrangements (see part 1, subpart X of this chapter) with entities
providing communications in support of public safety operations.
