The SDR tuner will allow us to receive the transmission but we need a good antenna tuned to the APT signals in order to receive a clear picture. So a small, cheap ~$15 radio dongle, containing two chips the RTL2832U and R820T tuner IC, is capable of recieving radio signals that cover a broad range, 25MHz-1700MHz, of the spectrum. It all starts with a simple SDR (Software Defined Radio) which is a radio where the traditional and complicated parts, the modulators and amplifiers, are now done by computer software rather than the hardware. This instructable covers everything you'll need to get started in being able to receive the APT (Automatic Picture Transmission) signals from the NOAA Satellites (NOAA-15, 18, and 19) flying overhead (and can be a foundation for listening to other satellites as well).
