HD Radio™ multicast channels (FM only)
In addition to digital sound quality, HD Radio technology gives broadcasters the opportunity to offer
more than one programming channel simultaneously using their existing frequency on the radio dial.
If the Recepter Radio
®
HD recognizes an HD Radio channel, the HD Radio logo starts blinking until
the signal is tuned in. After the Recepter Radio HD is tuned to an HD channel, arrows will appear on
the right side of the display. The arrows will indicate the existence of multicast services. Use the
Tuning
knob to select the multicast channels.

channel present – tune clockwise to hear it

Last multicast channel selected – tune counter-clockwise to return
to the main channel
Special information about delay in the HD Radio™ system
Digital systems inherently produce a delay in audio. To overcome this delay, HD Radio utilizes
a station’s current analog signal to enable fast tuning of an AM or FM station. After approximately
5 seconds, the audio will blend from analog to digital HD Radio. If the blend is smooth, the radio
station has implemented the HD Radio broadcast correctly. However, if the station has not, you will
experience a skip in content of approximately 5 seconds. This is not a problem with your Recepter
Radio
®
HD. This is an HD Radio broadcaster’s implementation issue, which should be corrected by
the station over time. Today’s analog is only present on the main channel. Should you tune directly
to a station’s multicast channel, the Recepter Radio HD will delay playing audio or content for
approximately 5 seconds. This is normal operation.
RBDS (Radio Broadcast Data System)
This radio supports RBDS, Program Identification and Radio Text. This function allows a radio
station to transmit free-form textual information that can be either static e.g. station slogans or in sync
with the programming such as the title and artist of the currently-playing song.
Example: 107.1 has two multicast channels.
