HD Radio (Hybrid Digital) vs Satellite Radio – Coverage, Price, and Technology

Just what is HD radio and how can it compare to Satellite Radio?

You’ve in all likelihood seen an increasing number of ads encouraging this new thing you have never heard of before: HD Radio. They say you can hear “undiscovered content” and digital quality sound. You almost certainly even heard the best section of the whole ad, “No subscription fee!”

I would like to help you learn a bit about HD Radio. I’ll try and make sure it stays simple so as to giving you all the info that you need with as little technical lingo as potential.

High definition isn’t High Definition

To begin with, when you have not learned of it and you most likely know of HDTV, I am guessing you live in a cavern. HD Radio really isn’t something similar as HDTV. The high definition in HDTV stands for High Definition. Don’t mistake this as the same in HD Radio because high definition in this particular context means Hybrid Digital.

Yet, it provides radio transmission that is considerably better than conventional radio signals. Some HD radio stations transmit 5.1 Surround Sound digital audio signals, letting you appreciate authentic concert-like encounter. You may be certain that more stations will choose this particular way of transmission later on.

Digital and Sub-Stations

HD Radio enables digital information to be air by various radio stations through the FM or AM frequencies. In addition, these digital transmissions might be sent on numerous sub-channels, enabling about three stations per frequency. This would triple the number of stations you may possibly listen to on HD Radio. What would it look like on the screen, you inquire?

Typically, conventional AM/FM radios would show the following: FM 104.7

On HD Radios, it’d show as: FM 104.7 HD-1 or 104.7 HD2 (with each high definition-X suggesting a sub-station)

As of 2007, the signal quality is reported to be close to CD-quality sound on the FM stations, which is an enormous jump in the radio business. Nevertheless, it’s exceedingly improbable for AM frequencies to experience this development since a considerably smaller band is operated on by the AM. Think of it as a hose. A smaller garden hose can barely deliver as much water as the hose of the fire department; and sadly, AM is that smaller garden hose.

Progress in Digital Technology

There were criticisms and reports in the first phases of HD Radio (2006) of noise and static when tuning in to these high definition stations. But, the technology has really advanced within the past two years and has enhanced isolation and signal quality. Do not worry about quality- loss much unless you are on the AM stations.
