THE EVOLUTION OF KMUW
Last month we included an article in Static about KMUW’s Signal
Expansion Project. A major component of the project is the
addition of digital FM broadcasting to Wichita Public Radio’s mission
of public service. Digital FM is referred to as HD Radio™ which
is, as the little symbol suggests, a trade mark from a company known as
iBiquity Digital.
iBiquity developed HD Radio technology and over 1,350 stations are
currently transmitting a digital signal. “HD” may make you think
of High-Definition, the terminology being used in the current
transition of television services. The use of HD for radio
doesn’t literally mean high definition, but the new technology is still
a significant evolution in the world of radio broadcasting.
On the TV side, stations have been required to convert to digital, and
the existing conventional, or analog, service will be terminated in
February 2009. On the radio side, as we mentioned last month,
KMUW’s analog FM won’t go away. The digital signal will be
combined with the analog signal at our new transmitter site, and
delivered through a single antenna.
The digital signal on our main channel will be a simulcast of our
current analog service. To pick up the new digital service,
however, you will need to acquire a radio capable of receiving HD Radio
transmissions. A number of national, regional and online
retailers offer a variety of home and car receivers. The NPRShop
at npr.org offers HD Radio items, and your purchase from NPR also
supports KMUW. Several auto manufacturers are including HD Radio
receivers in their new products. Your new radio will pick up
digital signals in your vicinity from stations operating an HD Radio
transmitter, as well as the existing stations broadcasting only in
analog.
One characteristic of the digital service is that it doesn’t fade out
like analog. When you’re out of digital range while listening to
the main channel, your receiver will switch you to the analog mode and
you shouldn’t miss anything. When you’re back in digital range,
your radio will automatically switch back to digital.
When KMUW implements HD Radio, we will increase the number of channels
from 89.1 FM and be able to offer a variety of new data services to
your radio. We have already acquired the license to use
iBiquity’s technology and have a digital transmitter ready for
installation. HD1 will be our primary digital channel – a
simulcast of our current schedule of news, information, music and
entertainment programming.
A second channel, known for the moment as “HD2” will include a mix of
music based on an A3, singer-songwriter, or World Café programming
model. We are developing a music library for this channel and
will program our own mix of music, while offering additional broadcasts
of World Café, Global Village, New Settlers Radio Hour and more.
When you’re tuned to Wichita Public Radio at 89.1 HD1, you will simply
tune up to HD2 on that FM channel to access the music mix on HD2.
We’re also finalizing our set-up for “HD3” which will be based on a
24-hour broadcast of the BBC World Service. Knowing that many
listeners find great value in access to global news and information, it
seemed natural to use one of our digital channels to provide this level
of world-wide coverage. Again, when you’re on 89.1, you’ll click
on through to HD3 for round-the-clock global news. We’ll also
have the option to include other news programs, specials and even local
news on HD3.
The channels will be available only in the digital mode – there will be
no analog simulcast of HD2 and HD3 like there is for the HD1 main
channel. Until we get the transmitter facility constructed and
the antennas on the tower, we’ll offer you the chance to sample the
programming for HD2 and HD3 by streaming them from our website.
Those streams will be up and running this summer.
Along with the compelling news and great music audio from our digital
service, your HD Radio receiver will be capable of displaying text
information on any of the three digital channels. We can offer
weather updates, song title, artist, emergency alerts or the phone
number to call to support Wichita Public Radio. Actually, we
don’t plan to do on-air fundraisers on HD2 and HD3…right away.
There will be additional expenses for the program content and the
equipment necessary to make it all possible, but we will be able to
offer these new program channels for a significantly lower cost than
what it would take to run three separate radio stations.
You can help us get these additional channels off the ground and on the
air by sending a contribution to KMUW for the Signal Expansion
Project. After you do that, be sure to check our website for
additional information and updates, and check back here next month for
the latest on the Evolution of KMUW.
