§ 74.1201 Definitions.
(a) FM translator. A station in the broadcasting service operated for
the purpose of retransmitting the signals of an AM or FM radio
broadcast station or another FM broadcast translator station without
significantly altering any characteristics of the incoming signal other
than its frequency and amplitude, in order to provide radio broadcast
service to the general public.
(b) Commercial FM translator. An FM broadcast translator station which
rebroadcasts the signals of a commercial AM or FM radio broadcast
station.
(c) Noncommercial FM translator. An FM broadcast translator station
which rebroadcasts the signals of a noncommercial educational AM or FM
radio broadcast station.
(d) Primary station. The AM or FM radio broadcast station radiating the
signals which are retransmitted by an FM broadcast translator station
or an FM broadcast booster station.
(e) AM or FM radio broadcast station. When used in this Subpart L, the
term AM broadcast station or AM radio broadcast station or FM broadcast
station or FM radio broadcast station refers to commercial and
noncommercial educational AM or FM radio broadcast stations as defined
in § 2.1 of this chapter, unless the context indicates otherwise.
(f) FM broadcast booster station. A station in the broadcasting service
operated for the sole purpose of retransmitting the signals of an FM
radio broadcast station, by amplifying and reradiating such signals,
without significantly altering any characteristic of the incoming
signal other than its amplitude.
(g) Translator coverage contour. For a fill-in FM translator
rebroadcasting an FM radio broadcast station as its primary station,
the FM translator's coverage contour must be contained within the
primary station's coverage contour. For purposes of this rule section,
the coverage contour of the FM translator has the same field strength
value as the protected contour of the primary FM station ( i.e., for a
commercial Class B FM station it is the predicted 0.5 mV/m field
strength contour, for a commercial Class B1 FM station it is the
predicted 0.7 mV/m field strength contour, and for all other classes of
FM stations it is the predicted 1 mV/m field strength contour). The
coverage contour of an FM translator rebroadcasting an AM radio
broadcast station as its primary station must be contained within the
lesser of the 2 mV/m daytime contour of the AM station and a 25-mile
(40 km) radius centered at the AM transmitter site. The protected
contour for an FM translator station is its predicted 1 mV/m contour.
(h) Fill-in area. The area where the coverage contour of an FM
translator or booster station is within the protected contour of the
associated primary station ( i.e., predicted 0.5 mV/m contour for
commercial Class B stations, predicted 0.7 mV/m contour for commercial
Class B1 stations, and predicted 1 mV/m contour for all other classes
of stations).
(i) Other area. The area where the coverage contour of an FM translator
station extends beyond the protected contour of the primary station (
i.e., predicted 0.5 mV/m contour for commercial Class B stations,
predicted 0.7 mV/m contour for commercial Class B1 stations, and
predicted 1 mV/m contour for all other classes of stations).
(j) AM Fill-in area. The area within the lesser of the 2 mV/m daytime
contour of the AM radio broadcast station being rebroadcast and a
25-mile (40 km) radius centered at the AM transmitter site.
