§ 90.250   Meteor burst communications.

   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 § 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 must not cause
   interference to other stations operating in accordance with the
   allocation table. New authorizations will be issued subject to the
   Commission's experimental licensing rules in part 5 of this chapter.
   Prior to expiration of the experimental authorization, application Form
   601 should be filed for issuance of a permanent authorization.
