17/5000 No NOAA pictures #95

Closed EA4GSX closed 4 years ago

EA4GSX commented 4 years ago

Hello I really like the project, it is very interesting but I have several problems. With the same configuration in windows I can decode more frames. Nor can I receive images from the meteorological satellites. Could it be the saturation of the LNA? Thanks in advance and congratulations on the project Captura

Hey,

Yes, it could be. Or antenna was not connected to the rtl-sdr. I cannot see anything on the spectrogram.

EA4GSX commented 4 years ago

Hello again The antenna was connected with NOAA you don't see a signal but with the rest you can see a lot of the Doppler. This is normal? Captura2

Hi! Yes, spectrogram contains the visualization of raw i/q data (.wav file) before applying any corrections to the data.

Okay Thank you very much for your help, finally, why could the problem be with the noaa? with the METEOR if I see a signal in the waterfall

Thank you

why could the problem be with the noaa?

Do you see the same picture for all NOAA satellites or just one pass had it?

EA4GSX commented 4 years ago

Hello The problem is with all NOAA passes
