When everyone thought that the last word on radio broadcast had been told years ago, there comes HDRadio (High Definition Radio) to shake up the radio broadcast business.

HD Radio is a new way of broadcasting radio that enhances the quality of the sound to levels not possible with the traditional, analog system. In short, what HDRadio does for radio is comparable to what HDTV does for TV - it makes the user experience much (much, much) better!

What makes this jump in quality possible? HD Radio technology works much like traditional analog transmissions (AM and FM) with a bonus. The difference is that the station broadcasting HD Radio technology also transmits an extra digital radio signal, which is piggybacked to its normal analog signal. The digital signal can also broadcast a third signal for text data, which is normally used to send information about the radio station, the current tune being played, even weather information.

On the other end, your radio receiver receives the signal - just as it does a regular AM or FM signal. But if you have a HD Radio receiver (like the Polk Audio I-sonic ES2), the receiver will decompress and decode the digital signal and play that signal instead of the regular analog one. The result? You get bright, clean, near-CD quality sound. In fact, when you listen to HD AM radio with a HD radio receiver, you’ll think you’re listening to FM. And when you listen to FM, you’ll think you’re listening to a CD.

Are you wondering how do you find HDRadio stations, say new country music stations? Easy enough, just point your browser to HDRadio.com and you’ll have a list of all Florida High Definition Radio stations, or anywhere else in the US. You can then find any HDRadio-compatible receiver and enjoy the superb quality of HDRadio broadcasts.

The sound quality of HD radio is clean, broad, and deep with no static to speak of. The high sound quality is not the only thing that makes HD radio a superior choice for your listening pleasure. HD Radio’s text-on-screen feature, that displays station name, track title and artist information is a nice addition to the usual frequency-only displays and if well used by the station, can provide a useful information feed to its listeners.
