HD Radio™ limitations
Limitations
Main channel vs. sub-channels (FM only):
•
The main channel is the only channel that
can receive in hybrid mode (both digital and
analog). 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
analog coverage area. Be aware that, like all
radio transmission technology, terrain, time of
day, vegetation and buildings can have a
positive or negative effect on radio reception.
Analog to digital/digital to analog blend-
•
ing: Analog to digital blending will occur as
the signal strength reaches a preset thresh-
old in the receiver. This will be noticeable in
fringe areas (areas with weak reception) and
is normal.

SiriusXM Satellite radio*
®
The SiriusXM Satellite system broadcasts from
of a number of high elevation satellites in geo-
synchronous orbit.
Listening to satellite radio
The digital signals from the satellites are line-of-
sight, which means that physical obstructions
such as bridges, tunnels, etc, may temporarily
interfere with signal reception.
Avoid any obstructions, such as metallic objects
transported on roof racks or in a ski box, or other
antennas that may impede signals from the
®
SiriusXM satellites.
