One of the most popular features of HD Radio Technology is the extra channels that you receive when you listen to HD Radio broadcasts.
These extra channels are called HD2/HD3 Channels, and are located on the FM dial, adjacent to your long-time favorite stations. Your
local radio stations are inventing all kinds of unique and fun to listen to HD2/HD3s Channels – everything from deep cuts, to classical, to
new music formats, to in-language programming and hosts of other creative stuff.
All you will need an HD Radio receiver. HD Radio receivers are available in many forms for car, portable and the home. You can select HD
Radio receivers from 17 different automakers as factory installed radios and from leading consumer electronics brands at more than 14,000
retail stores across the country.
How it works.
Basically, digital radio works the same as conventional radio. There’s a signal on one end and a receiver on the other. But there are a few key differences.
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 traffic, stock info and song titles can be sent out, as well.
The digital signal layer is compressed.
The combined analog and digital signals are transmitted.
Inevitably, radio signals bounce off objects, causing what is called multipath distortions. This is what causes the static in conventional radio receivers. HD Radio receivers are designed to sort through reflected signals, reducing static, hiss, pops and fades.
When the HD Radio broadcast signal reaches you, it arrives in a crystal clear, static free format that will amaze you and includes a wide array of data that appears on your radio display as useful text and/or images.
