In order to provide the best possible experience, use the contact form to
report any station issues found while listening to a station broadcasting
with HD Radio technology. Independent entities own and operate each
station. These stations are responsible for making sure all audio streams
and data fields are accurate.

Potential Reception Issues
If you are listening to a multicast station and
you are on the fringe of the reception area,
the station may mute due to weak signal
strength.
If you are listening to HD1, the system
switches back to the analog broadcast until
the digital broadcast is available again.
However, if you are listening to any of the
possible HD2 through HD7 multicast
channels, the station mutes and stays muted
unless it is able to connect to the digital
signal again.
When the system first receives a station
(aside from HD2-HD7 multicast stations), it
first plays the station in the analog version.
Once the receiver verifies the station is an HD
Radio station, it shifts to the digital version.
Depending on the station quality, you may
hear a slight sound change when the station
changes from analog to digital. Blending is the
shift from analog to digital sound or digital
back to analog sound.
