Hi all
Two months and two weeks ago I started groundstation #1627. The setup was quite easy, the learning curve hasn’t been too steep and the station (based on a Raspi 3B+ and a SDRplay) has been up&running for weeks. Sometimes I got some failures but it worked.
Two weeks ago – out of the blue (no change in the setup whatsoever) - it stopped working: no waterfall at all, anymore. I ran every troubleshooting routine I could find in the documentation with no success; I decided to reinstall everything from scratch on a brandnew SD card, following carefully the instructions e doublechecking every step. Once again it did not work. I made two further reinstallations – still no way to get a single observation.
Here are some data.
- curl https://network.satnogs.org is OK
- SDRplay is detected:

- Two days ago I got following message

I confess that I start to believe that the satnogs software is not as stable as it should be.
If someone could help me it will be greatly appreciated.
