Sec. 78.18 Frequency assignments.
(a) The Cable Television Relay Service is assigned the band of
frequencies from 12.70 to 13.20 GHz. This band is shared with the Fixed-
Satellite Service (earth-to-space) from 12.70 to 12.75 GHz and
Television Auxiliary Broadcast Stations from 12.70 to 13.20 GHz. The
following channels may be assigned to CARS stations for the propagation
of radio waves with the indicated polarization:
(1) For CARS stations using FM transmission:

(4) The Cable Television Relay Service is also assigned the
following frequencies in the 17,700 to 19,700 MHz band. These
frequencies are co-equally shared with stations in fixed service
[[Page 670]]
under Parts 21, 74 and 94 of the Commission's Rules. Applicants may use
either a two-way link or one or both frequencies of a frequency pair for
a one-way link and shall coordinate proposed operations pursuant to
procedures required in Sec. 21.100(d). These bands may be used for
analog or digital modulation.

(b) Television Auxiliary Broadcast Service stations may be assigned
channels in the band 12.70-13.20 GHz subject to the condition that no
harmful interference is caused to fixed CARS stations authorized at the
time of such grants. Translator Relay stations are assigned on a
secondary basis. New CARS stations shall not cause harmful interference
to television STL and intercity relay stations authorized at the time of
such grants. Television pickup stations and CARS pickup stations will be
assigned channels in the band on a co-equal basis subject to the
conditions that they accept interference from and cause no interference
to existing or subsequently authorized television STL, television
intercity relay, or fixed CARS stations. Channels in the 13.150-13.200
GHz band will be assigned exclusively to television pickup and CARS
pickup stations on a co-equal basis. A cable television system operator
will normally be limited in any one area to the assignment of not more
than three channels for CARS pickup use: Provided, however, That
additional channels may be assigned upon a satisfactory showing that
additional channels are necessary and are available.
(c) An application for a CARS station shall be specific with regard
to the channel or channels requested. Channels shall be identified by
the appropriate designations set forth in paragraph (a) of this section.
(d) For CARS Fixed stations using FM transmission with an authorized
bandwidth per channel of 25 MHz, to conserve spectrum applicants are
encouraged to use alternate A and B channels such that adjacent R.F.
carriers are spaced 12.5 MHz. As example, a fixed station in the CARS,
relaying several channels, would use A01, B01, A02, B02, A03, etc.
(e) For CARS stations using vestigial sideband AM transmissions,
channels from only the Groups C, D, E or F and those frequencies listed
in paragraph (a)(4)(ii) of this section normally will be assigned a
station, although upon adequate showing variations in the use of
channels in Groups C, D, E or F and those frequencies listed in
paragraph (a)(4)(ii) of this section may be authorized on a case-by-case
basis in order to avoid potential interference or to permit a more
efficient use. In situations where the number or the arrangement of
channels available in these groups is not adequate, or in order to avoid
potential interference, or in order to achieve the required VHF
channelization arrangement on the cable television system or for
repeated operations, or for two way transmission, or upon the showing of
other good cause, the use of channels in the Groups C, D, E or F and
those frequencies listed in paragraph (a)(4)(ii) of this section may be
authorized. Applicants are encouraged to apply for adjacent channels
within each group of channels, except that different channel
arrangements may be authorized when required to conform to the required
channelization arrangement at VHF on the cable television system, when
it is necessary to transmit non-adjacent off-the-air channels or signals
intended to fill non-adjacent slots in the spectrum, or to avoid
potential interference, or upon other showing of good cause.
(f) For vestigial sideband AM transmission, the assigned visual
carrier frequency for each channel listed in Groups C, D, E or F and
those frequencies listed in paragraph (a)(4)(ii) of this section shall
be 1.25 MHz above the lower channel-edge frequency. The center frequency
for the accompanying FM aural carrier in each channel shall be 4.5 MHz
above the corresponding visual carrier frequency.
(g) For CARS stations using double sideband AM transmission or FM
transmission with authorized bandwidth of no more than 12.5 MHz, Group K
channels normally will be assigned to a station, although upon adequate
showing variations in the use of channels in Group K may be authorized
on a case-by-case basis in order to avoid potential interference or to
permit a more efficient use.
(h) For double sideband AM transmission, the assigned carrier
frequency for each channel listed in Group K shall be 6.25 MHz above the
lower boundary frequency for each channel, and the sideband frequencies
corresponding to the carrier frequency of the accompanying FM aural
signal shall be 4.5 MHz above and below the visual carrier frequency.
[[Page 673]]
(i) All stations shall employ no more than a 12.5 MHz authorized
bandwidth per channel except in any one or more of the following
circumstances:
(1) The station is a CARS pickup station;
(2) The transmission path is more than 16.1 km (10 miles) in length;
(3) The station was authorized or an application was on file
therefor prior to July 26, 1973.
(4) Other good cause has been shown that use of a bandwidth of 12.5
MHz or less per channel would be inefficient, impractical, or otherwise
contrary to the public interest.
(j) Should any conflict arise among applications for stations in
this band, priority will be based on the filing date of an application
completed in accordance with the instructions thereon.
(k) Applicants for Group K channels shall apply for adjacent
channels and the requested channels shall overlap the least possible
number of Group A channels, except that different channel arrangements
may be authorized upon an adequate showing that the foregoing
arrangement cannot be used or would be contrary to the public interest,
or in order to avoid potential interference or to permit a more
efficient use.
(l) The band 13.15-13.20 GHz is reserved exclusively for the
assignment of CARS Pickup and Television Pickup stations on a co-equal
basis within a 50 km radius of each of the 100 television markets
delineated in Sec. 76.51. Fixed Television Auxiliary stations licensed
pursuant to applications accepted for filing before September 1, 1979,
may continue operation on channels in the 13.15-13.20 GHz band, subject
to periodic license renewals.
