After grabbing ISS SSTV images a couple weeks ago so I started looking at weather satellites on N2YO.com to see if I could pick up those signals. I noticed that NOAA 15 would be passing over this AM, so I grabbed my scanner and my RTL-SDR (and held a short 2m antenna to it since I don't have a connector). I can't access 1.7GHz but both of these can tune to 137.62 MHz. I was able to hear signal with RTL-SDR set to "Raw IQ" but not sure how to set that on the scanner. What to use to decode?
