This key fact that computer, not the chip, processes the signal, became a basis for creation of Software Defined Radio (abbreviated SDR) based on this platform and ushered in the era of RTL-SDR. Workflow of this device quite simple – built-in chip digitizes high-frequency signal, then computer and software extract desired frequency and information from it. Originally, no one guessed about other possibilities of this receiver other than digital television. Although DVB-T (not to be confused with DVB-T2) has not become widespread, the RTL2832U chip has become a real discovery for radio amateurs. Its main purpose to receive first-generation digital television broadcast on computers and portable media. But there is a very popular, and most importantly cheap device for receiving signals – DVB-T receiver with chip RTL2832U. ![]() Professional radio equipment for receiving or transmitting radio signals, like any other non-mass equipment – not cheap equipment. ![]() Today I will tell how to get a picture of the Earth from NOAA satellites within the city with a minimum set of equipment – an SDR receiver from RTL-SDR Blog and a conventional dipole antenna.
