Sec. 5.77  Change in equipment and emission characteristics.

    (a) A change may be made in a licensed transmitter without specific 
authorization from the Commission provided that the change does not 
result in operations inconsistent with any term of the outstanding 
authorization for the station involved.
    (b) Discrete changes in emission characteristics may be made without 
specific authorization from the Commission provided that the Commission 
is given written notification demonstrating that such changes will not 
exceed the maximum emissions envelope established in the existing 
authorization. Changes made pursuant to such notification that become a 
permanent part of the licensee's experimental program must be listed in 
the licensee's next application for renewal.
    (c) Prior authorization from the Commission is required before the 
following antenna changes may be made at a station at a fixed location:
    (1) Any change that will either increase the height of a structure 
supporting the radiating portion of the antenna or decrease the height 
of a lighted antenna structure.
    (2) Any change in the location of an antenna when such relocation 
involves a change in the geographic coordinates of latitude or longitude 
by as much as one second, or when such relocation involves a change in 
street address.
