keplers-updater-for-wxtoimg VS noaa-apt

GOES sats are geostationary but the NOAA APT satellites are encircling the planet and you can pick them up. Old tutorial but still relevant, just use "noaa-apt" tool[0] instead of WXtoImg. https://www.rtl-sdr.com/rtl-sdr-tutorial-receiving-noaa-weat...

Sometimes WXtoIMG just discards parts of the recoding when the signal wasn't strong enough. In those cases I've had some luck running the recorded .wav file through noaa-apt to get the full image.

so the NOAA_APT decoder link on your guide did not work properly, By chance did you mean this link https://noaa-apt.mbernardi.com.ar/?

So far I only use it for noaa-apt program though.

Had this exact problem, the thing that I found is that GQRX records at the wrong sample rate, which WXtoImg can’t handle. However, https://noaa-apt.mbernardi.com.ar this utility did work for me. I’ll also note that WFM is the setting I use in GQRX, not AM

You should try noaa-apt too, it usually gives better results for me.
