Tuning A Station

HD Radio Multicast Channels (FM Only)

In addition to digital-quality sound, some HD Radio broadcasters offer multiple programs simultaneously using multicast channels on their existing frequency.

If the station offers multicast programming, “-1” appears next to the station frequency. Use the tuner buttons to select multicast channels. Tuning up the frequency band will take you to that radio station’s next subchannel, which would have a “-2” after its frequency.

Audio Delay In HD Radio Systems

Digital systems inherently produce an audio delay. The HDX3 uses a station’s analog signal to tune the station. After approximately 5 seconds, the analog audio blends to digital. The blend is typically smooth, but if the station has not implemented their HD Radio broadcast correctly, you may experience a skip. This is not a problem with your radio. It is a broadcast implementation issue, which the station should correct over time.

Only the main channel contains an analog signal. If you tune directly to a station’s multicast channel, the audio will delay for approximately 5 seconds. This is normal operation.

Note

HD Radio broadcasts in the AM band may terminate at night due to FCC regulations.

FAQ

Why does my audio quality change after a few seconds on some HD Radio stations?

HD Radio stations blend analog signals to digital HD Radio signals. The blend is typically smooth, but in some cases, the audio quality can take a few seconds to reach enhanced digital levels. This is not an issue with your HD Radio receiver.

What can I do if I my audio is not clear or I don’t hear any audio? If your radio audio isn’t clear or you don’t hear any audio, you may be experiencing one of the following conditions:

¤Check all connections, including power and antenna.

¤Is the radio muted? If so, unmute the radio or turn up the volume.

¤Is the radio in AUX mode? If so, your auxiliary device may not be sending audio signals or may not be correctly connected.

¤Is anything plugged into the headphone jack? If so, unplug it.

¤Is the signal too weak? If so, tune to a stronger station or reposition your radio and/or antenna.

¤If you are using an antenna other than the one supplied, make sure the antenna supports FM reception. If the antenna uses an FM trap, make sure the FM trap is off.

Note

If you are using an amplified antenna with adjustable gain, turn down the gain all the way and adjust slowly upward.
