If you do not know the HD radio, this is the new digital technology that radio broadcasters are burdened with the next great thing and the Earth Radio Savior.
First of all, the good news. The HD radio sounds much better than conventional radio. In fact, the sound of HD AM is almost as good as the FM radio and the FM sound is almost as clear, clear and clean as if listening to a CD. And since HD is digital, broadcasters may have multiple signals at the same frequency. This allows them to broadcast different programming of what is called the HD2 channels. For example, a old station can program sounds in & # 39; 70s and ' At normal frequency, classic rock is the " 60 on HD2 channel.
Another good news is that depending on who you believe, or even 1300 or 1500 stations in the United States broadcast HD radio.
The difference? HD Radio Alliance claims to have 1500 HD stations, but the FCC has only 1300 licenses in the file.
While the HD radio can give you great sound and although there are at least 1300 radio stations on the HD radio, you will not hear it. That is, without buying a HD radio. And HD radios are usually expensive. Only one low-cost entry-level desktop is available, the Radiosophy HD100 for $ 99.95. The next step is the RadioShack Accurian HD radio, which usually costs $ 199 and a $ 199.95 for a Sony unit. Then there is the Sangean HDR-1, whose manufacturer's recommended retail price of $ 249, followed by a $ 300 extra stratosphere.
Want HD radio in the car? The situation is even worse. There are few HD car radio available and most are only tuners and connected to existing radios – the best solution.
The hardest part of the HD2 channels is that programming – at least so far – is hardly enough or sufficiently innovative to buy HD radio.
What's so ugly is that the broadcaster can use HD2 channels to make something very creative like broadcasters in Britain where the digital radio has just picked up. Unfortunately, in the US, most broadcasters have chosen to use HD2 channels only in "variations of themes" or in the normal programming variants (see the example of a rock station above).
So what's the future of HD radio? At this point, it does not seem clear, especially when compared to satellite and Internet radio. But as they say, "stay tuned more," because, well, it would be better.
