Sec. 74.751 Modification of transmission systems.
(a) No change, either mechanical or electrical, may be made in apparatus
which has been certificated by the Commission without prior authority of the
Commission. If such prior authority has been given to the manufacturer of
certificated equipment, the manufacturer may issue instructions for such
changes citing its authority. In such cases, individual licensees are not
required to secure prior Commission approval but shall notify the Commission
when such changes are completed.
(b) Formal application (FCC Form 346) is required for any of the following
changes:
(1) Replacement of the transmitter as a whole, except replacement with a
transmitter of identical power rating which has been certificated by the FCC
for use by low power TV, TV translator, and TV booster stations, or any
change which could result in a change in the electrical characteristics or
performance of the station.
(2) Any change in the transmitting antenna system, including the direction
of radiation, directive antenna pattern, antenna gain, transmission line
loss characteristics, or height of antenna center of radiation.
(3) Any change in the overall height of the antenna structure, except where
notice to the Federal Aviation Administration is specifically not required
under Sec. 17.14(b) of this chapter.
(4) Any horizontal change of the location of the antenna structure which
would (i) be in excess of 152.4 meters (500 feet), or (ii) require notice to
the Federal Aviation Administration pursuant to Sec. 17.7 of the FCC's Rules.
(5) A change in frequency assignment.
(6) Any changes in the location of the transmitter except within the same
building or upon the same pole or tower.
(7) A change of authorized operating power.
(c) Other equipment changes not specifically referred to in paragraphs (a)
and (b) of this section may be made at the discretion of the licensee,
provided that the FCC in Washington, DC, Attention: Video Division, Media
Bureau, is notified in writing upon the completion of such changes.
(d) Upon installation of new or replacement transmitting equipment for which
prior FCC authority is not required under the provisions of this section,
the licensee must place in the station records a certification that the new
installation complies in all respects with the technical requirements of
this part and the station authorization.
