+ | ====== HOW TO ====== | ||
+ | |||
+ | We are broadcasting signals on the Frequency of 7067 khz. Like The signal | ||
+ | of Sputnik – it is not important want you are broadcasting its important | ||
+ | that you are broadcasting. Like the Signal of Sputnik 1957 the broadcast | ||
+ | itself is the politcal message. | ||
+ | |||
+ | Each Participant is sending who am i, where am i and i im attendance. 7067 | ||
+ | khz is a HAM-Radio Frequencies so if you want to be in the Network you | ||
+ | have to make the HAM Licence or find a Ham-operator who is working with | ||
+ | you. | ||
+ | |||
+ | ** How can i be participate**: | ||
+ | - Find an Ham-operator who has the knowledge and the devices to do this. | ||
+ | - Make a Ham Licence and buy the devices | ||
+ | - We are temporarly operating your node. | ||
+ | |||
+ | **Normal work during the year**:\\ | ||
+ | All nodes of the network are sending at diffrent time there callsign. The | ||
+ | shedule is coordinated at the Website 7067.stwst.at. Each station should | ||
+ | send not more then three times per day. | ||
+ | |||
+ | **Working during Events, Festivals and Exhibitions**:\\ | ||
+ | The radio jam session : The nodes of the Network are trying to reach an | ||
+ | designated destination (for Example an Exhibition) | ||
+ | |||
+ | **What kind of signal we do prefer**:\\ | ||
+ | We prefer signals with small bandwith like cw or sstv. With sstv you are | ||
+ | converting a picture into a audiofile and broadcast this audiofile with | ||
+ | SSB technologie. We also supporting and featuring WSPRnet.org. Wspr means | ||
+ | Weak Signal Propagation Reporte – In this technology you have very small | ||
+ | power consumation. With 2 Watt you can boadcast 2 times around the world. | ||
+ | The bandwith of information is also very low – about 32 bit in 5 minutes | ||
+ | But the common is SlowScanTV. SSTV working with Pictures and Pitcures are | ||
+ | very compatible to exhibitions with audience who has no knowledge about | ||
+ | informationtheorie. Once more: it is not important what you are | ||
+ | broadcasting its importand that you are broadcasting. | ||
+ | |||
+ | **Which devices can i use**:\\ | ||
+ | You can buy and build your own devices. But you also can buy a device | ||
+ | from us. We are offering a raspberry pi with a camera, touchscreen and | ||
+ | sdr (software defined radio). SDR is making a softwareradio for 7067 khz. | ||
+ | The cam on the system is automatically making the picture an broadcast | ||
+ | it. You only need a RF amplifier to broadcast the signal. | ||
