   Meteor burst communications may be authorized for the use of private radio
   stations subject to the following provisions:

   (a) Station operation is limited to the State of Alaska only.

   (b) The frequency 44.20 MHz may be used for base station operation and 45.90
   MHz for remote station operation on a primary basis. The frequencies 42.40
   and 44.10 MHz may be used by base and remote stations, respectively, on a
   secondary  basis  to  common  carrier  stations utilizing meteor burst
   communications.  Users  shall cooperate among themselves to the extent
   practicable to promote compatible operation.

   (c) The maximum transmitter output power shall not exceed 2000 watts for
   base stations and 500 watts for remote stations.

   (d) Co-channel base stations of different licensees shall be located at
   least 241 km (150 miles) apart. A remote station and a base station of
   different licensees shall be located at least 241 km (150 miles) apart if
   the remote units of the different licensees operate on the same frequency.
   Waiver of this requirement may be granted if affected users agree to a
   cooperative sharing arrangement.

   (e) The authorized emission designator to be used in F1E, F7W, G1E or G7W to
   allow for Phase Shift Keying (PSK) or Frequency Shift Keying (FSK).

   (f) The maximum authorized bandwidth is 20 kHz.

   (g) Station identification in accordance with  Sec. 90.425(a) or (b) shall only
   be required for the base station.

   (h)  Stations  may be required to comply with additional conditions of
   operation  as  necessary  on  a case-by-case basis as specified in the
   authorization.

   (i)  Stations  employing  meteor  burst communications shall not cause
   interference to other stations operating in accordance with the allocation
   table.  New  authorizations will be issued subject to the Commission's
   developmental grant procedure as outlined in subpart Q of this part. Prior
   to expiration of the developmental authorization, application Form 601
