[A-DX] DRM und keine Receiver am Markt.

["Wolfgang Bueschel_web" <BueschelW@xxxxxx>]

Man hat zwei grosse Probleme, bisher keine Receiver am Markt, sowie
Interferenz ausgelöst von Gleichkanal oder Nebenkanal AM Modus Stationen,
die den komfortablen DRM Empfang vollkommen verhindern. Also müsste man
eigentlich auch für getrennte Frequenzbereiche plädieren, oder ? ...

Aus dem NASB Newsletter dieser Woche:

DRM at HFCC HAINAN China conference in mid Febr, 2006.

(...)
Mrs. Fang Wang, (RTC China) stated, "DRM is still in experimental phase in
China. Eighty percent of the population are peasants. Most people do not
have enough money to pay current DRM receiver prices. It is not whether the
audience is able to afford it but if it is able to buy it or not. Right now
it is still uncertain if DRM will succeed in China."

Rachel Staviskaya, (VOR): "There is lots of interest in DRM. Lots of people
try to develop specific programming to fit DRM. I am hoping that in the next
two years we will see some development before national standards are applied
for DRM. We use Russian txs that have been reconstructed. We are
broadcasting on two txs and already have two more txs in St. Petersburg. The
problem is the bands (spectrum) are too congested. Because of this the
development is much weaker. People in the country wonder why they should
spend so much money on this. For them it would be better to have domestic
broadcasts." In Moscow, two weeks ago, plans were mentioned for two
companies to produce inexpensive DRM receivers.

Burkard Beyer, (T-Systems Germany): " Most DRM broadcasts in the world are
SW and MW. We have three DRM MW txs in Berlin. We have many programs on the
air, but no receivers. We might get into problems if we aren't able to
produce inexpensive receivers."

Eugene Mueller, (Luxembourg - RTL) "We considered DRM as it was developing
to be a new (ideal) tool for advt. This is our main interest in it. We are
doing a full range of DRM broadcasts using MW & SW txs . We are also testing
our LW txions for DRM. We are broadcasting in MW and SW. We own 26 radio
stations in Europe. Our intent is to re-value our radio broadcasting. We are
also very concerned about the availability of receivers - this is a problem.
If the price doesn't come down, DRM will be in trouble."

Horst Scholtz (DWL): " Why did DRM start in Europe? Because Europe was ready
for the technology and willing to pay for the radios. (However figures of
analog receivers continue to grow as opposed to DRM.) For freq coordination,
"DRM" broadcasts are a problem and harder to coordinate around. Is it
practical to separate the SW bands with analog/DRM with two separate
systems? It would narrow the band usage if we did this (especially in the
lower bands.) Should the ITU decide, or will the HFCC-ABU?"

Horst noted that most complaints are from DX clubs.

Rachel noted that one of the goals years ago was to work on the same
frequencies.

Sharad noted we would lose flexibility dealing with SSN activity.

Note: The primary concern among the members at the HFCC conference is
whether or not we will see affordable receivers for DRM. There are yet to be
potential receivers for international usage.
