DPØGVN WSPR Beacon in Antarctia is operational
On January 15 in the afternoon hours, the multiband receiver of the new
permanent WSPR beacon *DPØGVN* in Antarctica was put into operation. It is
active from the German research station "Neumayer III" of the Alfred
Wegener Institute for Polar and Marine Research. The installation is part
of a scientific project of the Technical University of Munich in
cooperation with the University of Bremen and the German Amateur Radio Club
(DARC).
The beacon is still under test and will be shut down occasionally for more
configuration and optimization of antennae and software before it can be
mounted to the final installation site in a few weeks. Currently, there are
three radio specialists at the research station, all beeing HAM operators
and DARC members (Felix DL5XL, Matthias DH5CW, and Daniel, DL1SU).
The technology used consists of a WSPR multiband receiver based on a Red
Pitaya mini computer, it can simultaneously monitor up to eight HAM bands
from 160m to 6m and feed several hundred receive reports per hour into the
WSPR-Net. Meanwhile, the 5 Watt multiband transmitter has also been
commissioned, working into a 5m Procom vertical antenna matched with a
network.
The first operating results have positively surprised all project
participants. After a few days in service, DPØGVN has received several
thousand beacons spots already. This is due to an extremely quiet location,
far from any human civilization and man-made noise sources. The beacon
project in Antarctica was initiated by two professors, who are also radio
amateurs. One is Prof. Dr. med. Ulrich Walter, DG1KIM, scientific astronaut
of the ESA and professor of space technology at the Technical University of
Munich. Also involved is the well-known SDR specialist Prof.Dr. Michael
Hartje, DK5HH, from the University of Bremen, who takes care of the
software solutions.
The DARC is closely involved in the project, as the worldwide community of
radio amateurs allows a "swarm project" in order to generate the database
for systematic scientific evaluation of the propagation paths in polar
regions. The devices for this scientific project were built by a group of
volunteer German radio amateurs.
