Welcome to PA1PJ's APT POLAR WEATHER SATELLITE
Simple receive and decode APT-signals from NOAA
weather satellite.How ?
Connect a 137-138 MHz receiver to the
soundcard of your PC , record the signal of the satellite as a
wave-file , use decode software and finally you have nice images.
Difficult ? Just try.In case of trouble
