A lot of people are curious about HD radio, but they don’t quite know what it is. HD radio uses today’s digital technology to broadcast instead of the old analog technology. It sounds so much better than analog broadcasting, the difference is nothing short of astounding. You can check out the difference online. Some stations make their digital broadcasts available on the web so you can hear the difference for yourself.
Once you buy an HD radio receiver, the broadcasting is free. If you buy a quality receiver, you’ll have a great sound system that lets you enjoy more than just HD radio broadcasts. The Polk i-Sonic ES2 system features a built in iPod dock and iTunes tagging. You can collect and store information on the songs you enjoy listening to on HD radio, then decide which ones to buy.
There’s one more advantage to HD radio, and that’s multicasting. If you have a favorite country music station, it may be broadcasting several other channels to supplement its main programming.
In some cases, these HD2 channels are like completely new country music stations. Take just one state as an example. With 110 Florida High Definition Radio stations broadcasting, there are 181 channels available.
