ALASKAN COMPANY TO TEST NEW SHORTWAVE TECHNOLOGY By Bob Brewin, 07/18/08

The Federal Communications Commission on Tuesday granted an Alaska company a
two-year experimental license to establish a radio station that will test
new shortwave technology that the Defense Department eventually could use to
support intelligence operations.

Comment on this article in The Forum.Digital Aurora Radio Technologies,
based in Delta Junction, Alaska, said in its license application with FCC
that it planned to use a new open standards broadcast technology called
Digital Radio Mondiale to blanket the entire state with crisp, near FM
quality signals. It plans to transmit signals from Delta Junction, which is
95 miles southeast of Fairbanks. Shortwave broadcasters such as the BBC and
Radio Australia currently use DRM.

DRM could be used for military purposes in much the same way the British
used the BBC's shortwave services during World War II to transmit
programming to occupied Europe and beam coded messages to agents operating
behind enemy lines, radio analysts said. The company told FCC that its
initial tests would be funded by and conducted for the Defense's Joint
Electromagnetic Technologies program, a classified operation whose mission
is to develop technologies for use by special forces and intelligence units.

Defense also will supply surplus transmitters from the closed, Cold War-era
Over the Horizon Radar, located in Delta Junction. The radar system bounced
shortwave signals off the ionosphere to detect aerial targets, such as
Soviet bombers, at ranges up to 1,800 miles.

Digital Aurora provided numerous details in its filing about its broadcast
operations, but offered no information on its tests for the Joint
Electromagnetic Technologies program. The company said the purpose of the
project is to provide a terrestrial digital radio service for the citizens
of Alaska, and if digital transmission proves reliable, it will seek
partnerships with content providers with priority given to nonprofit
organizations.

Whit Hicks, Digital Aurora's president who also is the chief executive
officer of the Delta Mine Training Center in Delta Junction, declined to
identify the military purposes of the DRM shortwave test in an e- mail
response to a query from Government Executive.

"We are still in the planning stage for our project and don't have much to
talk about now," he said. "Our project is fairly basic at this point. We are
just trying to determine if the theoretical propagation predictions hold up.
If they do, we will see where it takes us. Until then its just basic
research. Give us a year to see how things work."

Digital Aurora did not did not indicate in its filing whether it intended to
broadcast programming during its two-year test. The company said it intends
to broadcast unspecified types of digital audio during testing to determine
the power levels needed to provide an adequate signal so that DRM receivers
can decode the signal with high reliability throughout the state.

DRM easily can be adapted to fit the requirements of Special Forces, said
Bennett Kobb, who runs a Web site advocating the use of DRM technology for
development of a low-power broadcasting service in the United States in the
26 megahertz wave band. He said because DRM is a digital technology, it
could be used to transmit data, imagery and maps to deployed forces.

But the narrowband high-frequency channels DRM operates at frequencies
between 4.4 megahertz and 10 megahertz limit throughput. DRM transmits at a
rate between 3,600 and 5,400 bits per second, according to industry
estimates. That's far below high-speed Internet connections, which provide
throughput in megabits per second.

Eric Johnson, professor of electrical and computer engineering at New Mexico
State University in Las Cruces, N.M., said DRM could be used as a one way
broadcast medium to support military operations. Johnson, who has helped
develop high-frequency data standards for NATO, said there have been
demonstrations using DRM to send charts to a ship sailing around Europe.

DRM could be used to send "change orders [and] map overlays to a team in the
field," he said. "It would be hard to disguise a high-power, encrypted
high-frequency broadcast, but with high-grade crypto, no one could read it
so all they would get is that we're sending data. [And there is] no way to
tell where it's going."

Johnson said DRM is not as robust as the Navy's High-Frequency Internet
Protocol system, which supports two-way transmissions at 9.6 kilobits per
second. "But DRM isn't bad, and the receivers are getting really
inexpensive," he said.

So wie ich es verstanden hab, sollen dazu doch wohl ausrangierte HAARP-
Sender benutzt werden. HAARP benutzt wohl 20 kW Einheiten, die dann
zigfach (mehrhundertfach?) zusammengefaßt sind. Aber eine derartig
steilstrahlende Antenne wie bei HAARP? Damit sollte zwar guter lokaler
Empfang möglich sein, wobei man dabei sicher nur recht tiefe
Frequenzen nutzen kann. MUF ist jetzt das Stichwort. Als DX-Übung
sollte das eine ziemliche Herausforderung werden. Das Wasser einer
Fontäne pladdert schließlich auch nur im direkten Umkreis um den
Springbrunnen runter, nicht weit entfernt wie bei einer
Feuerwehrspritze.
