Hi guys! I Hope you are doing well.
Some colleges and I are developing the SatNOGS project in Uruguay, we have recently construct a QHA antena to get some NOAA images. The problem we are seeing is that, at some point the images get all black. It happens for all our observations, here I left some examples.

Any input you can give is will be helpful or any tips about where to start debugging also. We believe It is a software “issue”, I believe that in some point the image decoder or FM demodulator stops and soon on the image is black.
Thanks in advanced!
