How HD Radio
TM
Technology Works
Basically, digital HD Radio receivers work the same as a conventional radio. There’s a
signal on one end and a receiver on the other. But there are a few key differences.
1. Instead of sending out one analog signal, stations send out a bundled signal – both
analog and digital. Because it is digital, textual data such as trafc, stock info and
song titles can be sent out, as well.
2. HD Radio technology enables FM broadcasters to offer several new channels of
digital programming in addition to their main station. To discover all of the new FM
stations in your city, please visit www.hdradio.com.
3. Inevitably, radio signals bounce off objects, causing what is called multi-path dis-
tortions. This is what causes the static in conventional radio receivers. Digital HD
Radio receivers are designed to sort through reected signals, reducing static, hiss,
pops and fades.
4. Finally, the signals reach their destination. Both HD Radio broadcasts are free, with
no subscription fee. To hear the digital broadcast, all you need is a digital HD Radio
receiver. To learn more about HD Radio technology, and to nd HD Radio stations,
please visit www.hdradio.com.
