§ 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.
