So what are the benefits of HD Radio Technology? We'll get into this in more detail later on, but here are some of the things that really appeal to the customers:

More music. More sports. More everything: Multiple channels of new content can be streamed over a single FM frequency, vastly increasing the range of programming. These new channels, called HD1, HD2, and HD3 channels, are found "adjacent" to traditional FM stations on the dial.

Amazing sound: AM now sounds as good as traditional FM, and FM now offers crystal clear CD-like sound without the hiss, static and pops of traditional analog signals.

Free: No subscription fee. No monthly payments. All listeners need to experience the benefits of digital radio is an HD Radio receiver or tuner.
