Q.
What is HD Radio?
A.
HD Radio has been described as “the most significant advancement in radio
broadcasting since the introduction of FM stereo.”
Instead of relying solely on analog broadcasts, FM and AM stations now
also have the ability to broadcast their programs digitally, a change that
offers multiple advantages.
-
More Programming Options
-
Improved Fidelity
-
No Audio Distortion
HD
Radio provides better fidelity than AM or FM. For
AM-HD Radio, the difference is striking, though current rules limit digital
broadcasts on AM stations to daylight hours.
For
FM, the improvement in fidelity is more subtle.
FM-HD Radio's big advantage is its ability to multicast -- that is, to
carry more than one program service at the same time on the same frequency.
This provides stations the ability to double and even triple the amount
of programming offered to listeners who have new HD radios.

Q. How will Northwest Public Radio
take advantage
of the multicasting capability?
A.
NWPR broadcasts two program services, and we plan to put both services
on all our FM digital stations (because of narrower channels, this multicasting
capability will not be available on AM, nor is it currently authorized for FM
translators). In the case of KNWY
in Yakima, for example, this means our
NPR and Classical Music service will continue to be on the
analog side and on 90.3-HD1 on the digital side. NWPR's
NPR News service can be tuned in on 90.3-HD2.
Eventually (meaning when there are a sufficient number of
receivers in listener hands), our plans are to add an HD3 service that will be
something entirely different.
To
summarize, this will be the initial configuration for stations currently
providing our
NPR and Classical Music service (KZAZ, KNWV, KNWO, KRFA, KNWP,
KFAE, KNWR and KNWY):
Analog/HD-1:
NPR and Classical Music
HD-2:
NPR News
HD-3: To Be Determined
And,
except for KWSU-AM, this will be the initial configuration for FM stations
currently on our
NPR News service (KLWS, KQWS, KMWS, and KWWS):
Analog/HD-1:
NPR News
HD-2:
NPR and Classical Music
HD-3:
To Be Determined
Because
KWSU-AM does not have multicasting capability, it will continue to provide only
our
NPR News service, but of course most KWSU listeners can also
receive KRFA or KNWV.
Both our program
services are also available,
streamed as they are broadcast, from our web-site.

Q. What are Northwest Public
Radio’s plans for converting
its stations to HD Radio?
A.
The first Northwest Public Radio station to be converted to HD was KNWY
in
Yakima
. It was completed in
December, 2006. KWSU-AM in
Pullman
will follow in early 2007. Also
planned for early 2007 is KMWS in
Mount
Vernon
. KMWS will be
converted to HD as part of a significant upgrade to that station.
Three
more stations are scheduled for completion in 2007.
The tentative schedule includes KFAE (Tri-Cities) in the spring,
followed by KNWR (Ellensburg/Wenatchee) in the summer and KLWS (Moses
Lake/Ephrata) in the fall.
We
have received a commitment for federal funding for all 13 of our stations and
are in the process of raising the local portion.
We're hoping to convert all 13 to HD Radio within the next two or three
years pending successful completion of fundraising efforts.
Q. Will I need to buy a new radio?
A.
To enjoy the benefits of HD Radio,
you will need to buy a new radio. More
and more HD radios are coming on the market, and prices are dropping
rapidly and some good ones are already available under $200.
Click
here for more information on the products currently available.
If
you purchase a new HD radio, you will encounter the realities of digital
transmission. If you have a
digital cell phone or one of the new digital television receivers, you know
that digital transmission is "brittle." It's
either perfect or not there at all. There's
no gentle fading away as in the case of analog. Unlike
your digital cell phone or digital television, though, the main channel of HD
Radio is designed to simulcast the analog programming.
When fading occurs, the digital signal will blend into the
analog signal, so you won't lose service. For
the 2nd and 3rd HD Radio channels, however, this will not be available, so you
will experience a smaller reliable coverage area for those program services
than for the main one.
Q.
If I am satisfied with the current
service I receive from Northwest Public Radio, will I still have to buy a new
radio?
A.
No. The
digital program information is embedded within the existing AM or FM signal, so
those analog signals will not go away.
Q.
Is there a fee for this service as
there is for satellite radio?
A:
No.
The HD-1, HD-2 and HD-3 services will be free.

Q.
What factors will affect my HD Radio reception?
A.
Based on our limited experience with this new technology, here is some general
information on HD reception. As always, reception depends on proximity to the
transmitter site and lack of blocking terrain.
·
HD radio reception in vehicles is generally strong.
·
HD radio reception in wood-frame homes should be strong.
·
HD radio reception in steel-reinforced buildings is problematic,
especially on the first floor of such buildings. Reception improves near
windows and on higher floors.
Additionally,
and this is a very important point, good FM antennas are critical to HD
reception. At a minimum, a “T” antenna must be attached to the
radio with the top of the “T” in a straight line (horizontally or vertically)
and with the wire to the receiver perpendicular to the top of the “T” for a
foot or two. TV “rabbit ears” should also work as well. With either
antenna, a listener should experiment with positioning for best reception.
Q.
How much does is cost to convert stations to HD Radio?
A.
The current estimate to convert all Northwest Public Radio stations to
HD is about $1,663,000. The
federal grant program is providing about $1,188,000 toward this project.
We have also received generous support from the M.J. Murdock Charitable
Trust and the Paul Lauzier Charitable Foundation for the projects completed in
2006 and scheduled for 2007. The
amount still needed to complete the remaining stations is about $325,000.
