The Real Price of Home Satellite Radio

If your home stereo or entertainment system produces top quality sound, then the satellite radio will also. Or will it?


Aug. 24, 2007 — by John Pike

Millions love cruising in their cars to the huge channel lineups of music, news and sports with one of the two satellite radio companies, XM Satellite Radio Inc. or Sirius Satellite Radio Inc.

But for home use, some see satellite radio with ambivalence.

Satellite radio is digital and uses a binary code of ones and zeros. This means your radio either completely receives it or not at all. There is largely no in between, such as a signal marred by static, which often occurs on terrestrial (traditional) radio. But there can still be some distortion.

So for some, satellite broadcasts can be can virtually the only non-Internet radio available, especially for those who live or work within or near tall buildings. Living in urban skyscrapers, for example, might prevent you from receiving barely any local terrestrial radio.

Of course options exist to improve the signal, among which is changing the antenna or placing it either near or out the window.

Another option is ditching the traditional radio for satellite. Often its digital signal will get through when analog broadcasts will not. Sometimes the radio has to be moved around a bit to pick up a signal, but once it does you will never need to miss another erudite Howard Stern lecture on American sociology.

In case you can’t pick up Howard’s signal on the first try, Sirius sells an antenna with an option for an extension cable to place either near or running outside your window. A south-facing window is best for receiving a satellite signal. It also sells a gizmo called an echo signal repeater that allows you to place your radio where you want it most. Even in interior rooms, without restrictions due to antenna placement.

To listen to Sirius at home, you can purchase a Plug & Play Universal Home Kit, listed at $50 on its web site. Of course, you will need to purchase one of their radios, listed at between $40 and $120. The radio plan, or subscription to the broadcast signal, is another $13 monthly. Sirius also just announced a partnership with multiroom music system provider Sonos to conveniently stream the satellite’s Internet stations throughout the house.

XM has similar accessories, with tuners ranging from $40 to $250 on its web store (along with rebate offers).

You can also connect the satellite radio into the back of your amplifier, possibly the auxiliary jack. If your home stereo or entertainment system produces top quality sound, then the satellite radio will also.

Or will it? Here is where folks disagree.

Some say they hear compact disc quality music coming out of their home-based satellite radio, or at least as good as terrestrial radio. They’ll jump up and down on their couch like Tom Cruise to attest to its high quality sound.

But some experts say satellite sound quality is relatively poor compared with compact discs—or even terrestrial radio, especially for the music stations. Without the problems of analog, it often has CD clarity, but not the quality.

Sheer numbers tell that story. Satellite service providers send only one digital signal to each receiver. The signal is then split into hundreds of audio streams. The ones for voice are very narrow, while others for music are slightly wider. These audio streams may run from a few kbps for talk stations to 60 kbps for music channels.

Both satellite companies compress their steams to cram as much as they can down that thin line of bandwidth.

Satellite radio stations compress and expand their audio streams at a much lower rate than many MP3s. Some will defend the sound of a 128 kpbs MP3 file (that’s the standard bit rate for tracks sold on iTunes, for example), which is not even close to CD quality, but it’s more than double 60 kbps.

Some experts say an FM station is far superior. Compare the difference to hearing a live symphony versus on a transistor radio outdoors.

The ratio or split of bandwidth is also adjusted based upon the time of day, such as rush hours and evenings. Talk stations and rush hour programs get low bandwidth because it is mostly talk, which is satisfactory. But when quality matters, the music stations can suffer.

Some experts say there is more compression and low-quality sound on stations with the fewest listeners, pointing to classical stations as potentially at the bottom end.

And one final bit of caution before you purchase your satellite equipment. XM, Sirius and federal officials have been recently discussing a proposed merger of the two companies—who knows how that would affect pricing and sound quality.
