The main channel is the only channel that
can receive in hybrid mode (both digital and
analogue). If a frequency has sub-channels,
they are broadcast in digital mode only. The
main FM channel will be displayed as, for
example, "WRIF-FM HD1". The sub-FM
channels will be displayed as"WRIF-FM
HD2", "WRIF-FM HD3", etc.

Reception coverage area: Due to current
IBOC transmitter power limitations, the
reception coverage area in digital mode is
somewhat more limited than the station's
analogue coverage area. Please be aware
that as with any radio broadcast technology,
terrain, time of day, foliage level and building
location can have positive or negative effects
on radio reception.
•
Analogue to digital/digital to analogue
blending: Analogue to digital blending will
occur as the signal strength reaches a preset
threshold in the receiver. This will be noticea-
ble in fringe areas (areas with weak recep-
tion) and is normal.
