    (a) An AM, FM or TV transmitter may be type accepted or notified 
upon the request of any manufacturer of transmitters following the 
procedures described in Part 2 of the FCC Rules. If acceptable, the 
transmitter will be included in the FCC's ``Radio Equipment List, 
Equipment Acceptable for Licensing.'' Since March 5, 1984, these 
transmitters have been authorized under notification.
    (b) A permittee or licensee planning to install and use as a main 
transmitter one not included on the FCC's ``Radio Equipment List'' must 
obtain authority to use such a transmitter by filing for a construction 
permit on FCC Form 301 (FCC Form 340 for noncommercial educational 
stations). The application must include a complete description and 
circuit diagram of the transmitter, description of the carrier frequency 
determining circuits, complete operating parameters, and measurement 
data as would be requlred for a grant of type acceptance. A permittee or 
licensee planning to modify a transmitter which is included on the FCC's 
``Radio Equipment List'' or for which an FCC Form 301 has been submitted 
and approved, must follow the requirements contained in Sec. 73.1690.
    (c) A transmitter which was in use prior to January 30, 1955, may 
continue to be used by the licensee, and successors or assignees, if it 
continues to comply with the technical requirements for the type of 
station at which it is used.
    (d) AM stereophonic exciter-generators for interfacing with type 
accepted or notified AM transmitters may be type accepted upon request 
from any manufacturer by the procedures described in part 2 of the FCC 
Rules. Broadcast licensees may modify their type accepted AM 
stereophonic exciter-generators in accordance with Sec. 73.1690.
    (e) Additional rules covering type acceptance and notification, 
modification of authorized transmitters, and withdrawal of a grant of 
authorization are contained in part 2 of the FCC Rules.
