HD Radio® Broadcasting in Your Future?

Nautel has you covered, thanks to our field-proven, high performance HD Radio solutions, and ongoing R&D in digital radio technology.

About HD Radio

HD Radio is Xperi’s “in-band on-channel” (IBOC) digital radio technology that lets broadcasters build digital capabilities without sacrificing their established analog frequency and audience.

Start by simply adding a high-quality digital copy of your existing analog content to your FM or AM transmitted signal. Analog listeners will see no change, but customers with digital receivers will now receive the high-quality digital signal. Signal fading, static, hisses, and pops will be a thing of the past. And HD Radio is all FREE for consumers, just like today’s analog AM and FM radio.

FM broadcasters can choose to add up to three new digital channels and new digital data content, all on your original station frequency. Data services such as displayed song and artist information, weather and traffic alerts, and more will revolutionize the way your customers experience AM and FM radio.
