NOAA 18 weather satellite image received on May 25, 2021 with an AirSpy Mini SDR on GQRX SDR app and a DIY satellite antenna. The signal was recorded in WAV sound format and then decoded (converted to image) with the NOAA-APT decoder. NOAA satellites (15, 18, and 19) transmit weather images in APT (Automatic Picture Transmission) format at 137 MHz which may be received using just a VHF antenna, a software-defined radio (SDR), and an APT decoder.
