At HMKV Dortmund in the Workshop [[Satellite Border Footprint|Satellite/Border/Footprint]] the question came up if it would be possible to send directly to a satellite. During the workshop a lot of art projects were shown, that work with received satellite data. The shown projects update the already existing Artist Working With Satellites List by [[Max Neupert]]. [[Satellite Border Footprint/Lisa Parks|Lisa Parks]] showed satellite TV enthusiasts covering their whole house with sat dishes to receive a broad range of signals.

During the workshop Satellite/Boarder/Footprint at HMKV the question cam up if it is possible to send directly to a satellite. During the Workshop several was of receiving satellites came up. A lot of art projects receive satellite data shown during the workshop and stored in the allready existing Artist Working With Satellites List by Max Neupert. Lisa Parks showed satellite TV enthusiasts covering their whole house with sat dishes to receive a broad range of signals. She showed as well improvised, handcrafted dishes made of metal pots. So there are ways to receive.

Its allowed to send in some of those frequencies, like in the 2.4 Ghz frequency used for WiFi internet and other civil transmission.. Most other Frequencies are forbidden for public use.

Those postcards are in a special For special events Radio Amateurs search in cars wih mobile systems for hidden transmitters.

Send it via outer space

Some thoughts and ideas on satellite transmission

How can I send via Satellite

At HMKV Dortmund in the Workshop Satellite/Border/Footprint the question came up if it would be possible to send directly to a satellite. During the workshop a lot of art projects were shown, that work with received satellite data. The shown projects update the already existing Artist Working With Satellites List by Max Neupert. Lisa Parks showed satellite TV enthusiasts covering their whole house with sat dishes to receive a broad range of signals. She showed as well improvised, hand crafted dishes made of metal pots. So there are ways to receive. But is it possible to send information directly via satellite in the context of an artistic project or open technology? Of course it is but realization depends on laws and at least on the budget. So what can one do? Collect information and calculate.....

Becoming a Ham Radio Amateur

One simple way to send via an satellite is to join the radio amateur community. Becoming a ham radio amateur is quite a hard work, but not very complicated. If you learned your lessons from a book, a CD-ROM or on line you can pass the test at your national agency, that is in charge for radio frequencies. In Germany this is the Bundesnetzagentur. The dates for the test in different cities around Germany are sown here.

"The Great Brazilian Sat-Hack Crackdown"

Wired reports the arrest of 39 people in Brazil hijacking of U.S. military satellite transponders.

"This had been happening for more than five years," says Celso Campos, of the Brazilian Federal Police. "Since the communication channel was open, not encrypted, lots of people used it to talk to each other."

Some recordings of the transmissions were recorded and uploaded to YouTube: http://www.youtube.com/watch?v=s5jFWxGeqSk http://www.youtube.com/watch?v=CnVYdByVvNc

Brazilian filmmaker Bruno Vianna just finished a documentary about this case, which is going to be released on September 15th.

Earth is covered by a dynamic shell of secret and official satellites. They are launched by states like China, USA, Japan, Russia, Germany, France, etc... for military and secret service applications. Beside official organisations like NASA, ESA, DLR, etc... numerous private concerns launch satellites. Those satellites stream live TV casts, transmit TV shows, send SMS or email and transfer data or voice through outer space around the world.
