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/Boarder/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 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. 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.....
Transmission

Sharing information via electro magnetic fields is a highly protected form of communication. A small number of frequencies can be received for several applications in everyday life e.g Radio(UHF), TV(UHF/Satellite), Internet 2.4 Ghz. surveillance cameras 2.4 Ghz, GPS,... 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. Radio Amateurs or Ham Radio Amateurs have the right to use some. To become a Radio Amateur one has to pass a quite complex test on technology and laws of radio communication. Unlike the untested public radio user Ham Radio Amateurs are allowed to send on the frequencies they are receiving. The Ham Radio community is a world wide network based on privat equipment reaching from very low level to highly advanced technology. Most of the Radio Amateurs search for signals comig from a far out place. The aim of transmission is as well to reach a far away receiver.
