Sec.  87.475   Frequencies.

   (a) Frequency coordination. The Commission will assign frequencies to
   radionavigation land stations and radionavigation land test stations after
   coordination with the FAA. The applicant must notify the appropriate
   Regional Office of the FAA prior to submission to the Commission of an
   application for a new station or for modification of an existing station to
   change frequency, power, location or emission. Each application must include
   the FAA Regional Office notified and date of notification.

   (b) Frequencies available for radionavigation land stations. (1) LORAN-C is
   a long range navigation system which operates in the 90–110 kHz band.

   (2) Radiobeacon stations enable an aircraft station to determine bearing or
   direction in relation to the radiobeacon station. Radiobeacons operate in
   the bands 190–285 kHz; 325–435 kHz; 510–525 kHz; and 525–535 kHz.
   Radiobeacons may be authorized, primarily for off-shore use, in the band
   525–535 kHz on a non-interference basis to travelers information stations.

   (3) Aeronautical marker beacon stations radiate a vertical distinctive
   pattern on 75 MHz which provides position information to aircraft.

   (4) The following table lists the specific frequencies in the
   108.100–111.950 MHz band which are assignable to localizer stations with
   simultaneous radiotelephone channels and their associated glide path station
   frequency from the 328.600–335.400 MHz band.

   (6) The band 960–1215 MHz is available for the use of land stations and
   associated airborne electronic aids to air navigation. When distance
   measuring equipment (DME) is intended to operate with a single VHF
   navigation station in the 108–117.975 MHz band, the DME operating channel
   must be paired with the VHF channel as shown in the following table:

------------------------------------------------------------------------

   (7) 1300–1350 MHz: The use of this band is restricted to surveillance radar
   stations and associated airborne transponders.

   (8) 1559–1626.5 MHz: The use of this band is limited to airborne electronic
   aids to air navigation and any associated land stations.

   (c) Frequencies available for radionavigation land test stations. (1) The
   frequencies set forth in  Sec. 87.187(c), (e) through (j), (r), and (t) and
    Sec. 87.475(b) (6) through (10), and (12) may be assigned to radionavigation
   land test stations for the testing of aircraft transmitting equipment that
   normally operate on these frequencies and for the testing of land-based
   receiving equipment that operate with airborne radionavigation equipment.

   (2) The frequencies available for assignment to radionavigation land test
   stations for the testing of airborne receiving equipment are 108.000 and
   108.050 MHz for VHF omni-range; 108.100 and 108.150 MHz for localizer;
   334.550 and 334.700 MHz for glide slope; 978 and 979 MHz (X channel)/1104
   MHz (Y channel) for DME; 1030 MHz for air traffic control radar beacon
   transponders; 1090 MHz for Traffic Alert and Collision Avoidance Systems
   (TCAS); and 5031.0 MHz for microwave landing systems. Additionally, the
   frequencies in paragraph (b) of this section may be assigned to
   radionavigation land test stations after coordination with the FAA. The
   following conditions apply:

   (i) The maximum power authorized on the frequencies 108.150 and 334.550 MHz
   is 1 milliwatt. The maximum power authorized on all other frequencies is one
   watt.

   (ii) The pulse repetition rate (PRR) of the 1030 MHz ATC radar beacon test
   set will be 235 pulses per second (pps)  ±5pps.

   (iii) The assignment of 108.000 MHz is subject to the condition that no
   interference will be caused to the reception of FM broadcasting stations and
   stations using the frequency are not protected against interference from FM
   broadcasting stations.

   (d) Frequencies available for ELT test stations. The frequencies available
   for assignment to ELT test stations are 121.600, 121.650, 121.700, 121.750,
   121.800, 121.850, and 121.900 MHz. Licensees must:

   (1) Not cause harmful interference to voice communications on these
   frequencies or any harmonically related frequency.

   (2) Coordinate with the appropriate FAA Regional Spectrum Management Office
   prior to each activation of the transmitter.

   (e) Frequencies available for differential GPS stations. Frequencies in the
   112–118 MHz band may be assigned to Special Category I (SCAT-I) ground
   stations for differential GPS data links.

   (1) The frequencies available are on 25 kHz centers with the lowest
   assignable frequency being centered at 112.000 MHz and the highest
   assignable frequency being centered at 117.950 MHz.

   (2) Applicants must coordinate a frequency, time slot assignment, and
   three-letter identifier with the FAA and provide this information to the
   Commission upon application.
