NOAA 15 Satellite | 03 August 2022

NOAA satellites 15, 18, and 19 transmit weather images in APT format at 137 MHz which may be received using a DIY non-tracking circularly-polarized VHF antenna, an AirSpy Mini software-defined radio (SDR), and a decoder such as the NOAA-APT.

Receiving NOAA Satellite Image

NOAA satellites transmit weather images in APT format at 137 MHz which may be received using just a VHF antenna, a software-defined radio (SDR), and a decoder such as Wxtoimg running on a laptop.

My first weather satellite image decoded on December 3, 2020, as NOAA 18 passes over the Philippines.
