Short Description I was waiting for a pass from the satellite NOAA 18 when I was a choppy APT signal from what I assumed from NOAA 19, but a picture from WXtrack showed that its radio horizon was over 1,000 miles away from my location (the green cross).l I am not sure if this is some sort of signal propagation or if there was an old NOAA satellite that may have come back to life (I have seen articles from a few sources of how this might be).
