Sec. 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 (20 F1E, F7W, G1E or 
G7W).
    (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 574 should be filed for issuance of a permanent
