HD RADIO DISCOVERS STATIONS BETWEEN STATIONS
I
guess I'm dating myself once again when I say I remember as a kid
that my TV set had a channel dial from 2 to 13. Then we got TVs with
a UHF dial that held the exciting promise of more channels only to
discover that there was nothing ever good there. Today's TVs are
going digital and can get literally hundreds of channels with cable
and satellite programming. Even with just an antenna you can still
get lots of stations, especially if you live near a metropolitan
area. But what about radio?
There's a revolution happening in the radio world as well. Many
stations broadcast an RDS signal that gives equipped radios the
ability to display information about the programming it's playing
such as a song's artist and title. Satellite radio from XM and
Sirius offer hundreds of stations but the radios are costly and as
with cable and satellite TV, you must pay a regular subscription fee
to listen. But the TV you get over the air with an antenna, be it
analog or digital is still free and the same thing goes for the new
Hybrid Digital or HD Radio. Using the same old AM and FM analog
signal, they've discovered a way to piggy-back a better digital
signal.
This hybrid signal has the ability to not only carry a better
sounding radio, it can also carry along with it a lot more
programming. And it's all free.
With multicasting, they can broadcast two, even three different
programming channels. Let's say you are listening to 90.3 on the FM
band. With an HD radio, you can also get 90.3-1, 90.3-2 and even
90.3-3 if that station is offering it to be heard. And more and more
radio stations are doing just that because the equipment to make all
of this happen uses a stations existing broadcasting towers and
infrastructure. According to Radiosophy (www.radiosophy.com), the
makers of a little table-top HD radio, there are over 1700 stations
doing this right now. In fact, 90 percent of the US population can
tune in an HD station in their area and that continues to grow.
Radiosophy's HD100 radio can still tune in ordinary AM and FM
stations but when it detects an HD AM and HD FM signal, a little
blue indicator signals it's locked in. HD AM has the clear
static-free audio quality of an FM station and HD FM sounds like
you're listening to CD-quality audio. The HD100 has an LCD display
that describes the programming you're hearing along with the station
information. If it's music, you'll see the artist's name and song
title, playing time, and more. Talk stations will show relevant data
such as who is being interviewed for example.
The HD100 also offers features you'll find on a typical clock-radio
such as an alarm clock that beeps or plays stations to wake you, a
snooze button and even preset buttons you can set to 5 AM and 5 FM
locations that include the newer HD broadcast locations on the dial.
It also offers a headphone jack, an AUX out for your stereo system
and an input for your MP3 player to use its stereo speakers.
If you want to check if there's an HD station in your area, you can
go to the Ibiquity Digital website at www.ibiquity.com. You can
search for a station by state, city and market. Ibiquity is the
company that created the HD radio technology and makes the equipment
available to radio stations.
I want to make one thing perfectly clear here. Unlike satellite
radio where you can tune in all of the programming offered
regardless of location, the HD Radio signal comes from the local
radio stations to which you are tuning in. So you won't be able to
get more radio stations. You will however, be able to listen to more
offerings that are coming from those same radio stations in your
area that are multicasting their HD broadcasts.
Radiosophy's HD100 table radio is available only in a glossy black.
It sells for $99.95 and can be purchased directly from the
Radiosophy website.
The HD Radio broadcasts are free. Thank goodness something out there
still is.
