As the team has built a DVB-T transmitter, we will give a in-depth insight in how things are really done - including a demonstration of the transmitter.\n-\u003e For that we plan to stream the content of the 23C3 lectures locally on Alexanderplatz using TV channel 22. Don't forget to bring your DVB-T stick.
