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 be accompanied by a statement showing the name of the
FAA Regional Office notified and the 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; and 510-525 kHz.
(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.

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
