Report No. DC-2585         ACTION IN DOCKET CASE             April 18, 1994


      COMMISSION AMENDS TABLE OF ASSIGNMENTS FOR 450 MHZ AIR-GROUND 
                   STATIONS IN THE PUBLIC MOBILE SERVICE
                    (CC DOCKET NOS. 91-121 AND 92-137)

     The FCC has amended the table of assignments for the 450 MHz
air-ground stations in the Public Mobile Service.  It eliminated
interference problems with Canada and granted Mobile
Telecommunications Technologies Corp.'s (Mtel) request to move a
base station in Arizona.  The Commission denied the other pending
requests to allocate or reallocate frequencies for air-ground
service in these dockets.

     Air-ground radiotelephone service in the 450 MHz band is a
public radio service between base stations and airborne mobile
stations.  In creating the air-ground service, the Commission
adopted the goal of encouraging the provision of a nationwide air-
ground service utilizing the minimum amount of spectrum necessary. 
The Commission recognized that its allocation of 12 air-ground
channels would permit nationwide service if the channels were used
in sufficiently separate geographic areas.

     The Canadian Government notified the FCC that it was receiving
interference to its Toronto facility from the Commission's
allocation of channel 12 in Pittsburgh, PA.  The Canadian
Government asked the Commission to consider moving channel 10 from
Washington, D.C. to Pittsburgh.  To avoid this interference
problem, the Commission has moved channel 10 from Washington to
Pittsburgh and deleted channel 12 from the Pittsburgh area.

     In addition, Canada also stated in its letter that it
anticipated interference from channel 9 in Seattle, should that
channel be activated. To avoid potential interference, the
Commission has deleted channel 9 from Seattle.  

     Mtel proposed moving its facility from the Grand Canyon
Airport to Williams, AZ.  Mtel proposed this change because of the
inefficiency of operation at the Grand Canyon Airport.  An
engineering review of Mtel's  proposal revealed that no co-channel
interference would result from the move to Williams, AZ. The
Commission found that the public interest will be served by this
relocation and therefore deleted channel 12 from Grand Canyon, AZ,
and assigned it to Williams, AZ.

                                  (over)

                                    -2-

     The Commission declined to move channel 9 from Newark, NJ or
channel 2 from Boston to Laurel Run, PA.  It found that the
suggested reallocations would not be in the public interest.

     Additionally, the Commission reaffirmed the need for
substantial co-channel separation when it declined to allocate
channel 3 in Schaller, IA.

     Action by the Commission April 6, 1994, by Report and Order
(FCC 94-83).  Chairman Hundt, Commissioners Quello and Barrett.
