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.

Tuning A Station

1. 

Press the Volume/Mode knob on the 

HDX3

 console or 

MODE

 on the 

remote control to select either an 

AM

 or 

FM

 mode.

2. 

Use the tuner buttons on the 

HDX3

 console or on the remote control 

to select a station.

3. 

To search for a station, press and hold the tuner buttons. When the 

HDX3

 recognizes an HD Radio channel, the HD Radio logo appears.  

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. 

Saving Stations Into Preset Memory

HDX3

  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.
