Sec. 74.1201 Definitions.
(a) FM translator. A station in the broadcasting service operated for the
purpose of retransmitting the signals of an 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 FM broadcast service to the general public.
(b) Commercial FM translator. An FM broadcast translator station which
rebroadcasts the signals of a commercial FM radio broadcast station.
(c) Noncommercial FM translator. An FM broadcast translator station which
rebroadcasts the signals of a noncommercial educational FM radio broadcast
station.
(d) Primary station. The FM radio broadcast station radiating the signals
which are retransmitted by an FM broadcast translator station or an FM
broadcast booster station.
(e) FM radio broadcast station. When used in this Subpart L, the term FM
broadcast station or FM radio broadcast station refers to commercial and
noncommercial educational FM radio broadcast stations as defined in Sec. 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. The coverage contour for an FM translator
providing “fill-in” service is congruent with its parent station: For a
fill-in translator for a commercial Class B station it is the predicted 0.5
mV/m field strength contour; for a fill-in translator for a commercial Cass
B1 station it is the predicted 0.7 mV/m field strength contour; and for a
fill-in translator for all other classes of commercial stations as well as
all noncommercial educational stations it is the predicted 1 mV/m field
strength contour. A fill-in FM translator's coverage contour must be
contained within the primary station's coverage contour. 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).
