HD Radio technology is a method of transmitting audio and data. It transmits digital information instead of analog. HD Radio technology represents the evolution of traditional radio broadcasting into the digital age. | |
| HD Radio technology allows WUMB to transmit a high-quality digital signal. For you the listener, the benefits are: | |
 |
FM radio with CD-quality sound |
|
AM radio that sounds as good as FM |
|
No more static, pops, crackles or fades |
|
Transmission of additional information, such as song titles |

| How it works | |
| HD Radio technology works pretty much just like traditional analog radio transmission: | |
| 1. | WUMB sends out the analog and digital radio signals, along with a third signal for text data. |
| 2. | The digital signal is compressed before being transmitted. |
| 3. | The three-layered signal is transmitted from the radio station's upgraded digital transmitter. |
| 4. | Multipath interference, caused by the signal reflecting off of buildings, is ignored by the digital radio, which is able to discern the true signal and ignore interference. |
| 5. | Your radio receives the signal and, depending on your equipment, you hear either the digital or analog feed. |

What HD Radio technology is not |
| HD Radio technology is not a subscription service, like satellite radio. It is the same free, over-the-air broadcast radio that we've always known. Only better. It is not something that consumers have to buy into. Everyone can choose to continue listening to their current radios, but eventually all AM/FM radios will incorporate digital technology. It is a natural evolution of the medium. Soon, if you turn on a radio, you'll be listening to an HD Radio tuner. |
| HD Radio technology is not a competitor of satellite radio. It is an improvement to terrestrial AM and FM radio. Satellite radio is an alternative to terrestrial radio, in the same way that cable or satellite TV are alternatives to broadcast television. Even if you do have satellite radio, there are often times when you want to listen to local radio. |
