Hi all,
Having an issue getting my station up and running, and have spent substantial time reading and troubleshooting before this post. I’m guessing this is likely a PEBKAC issue (Problem Exists Between Keyboard And Chair), though could use some advice.
Thanks in advance.
Problem:
After installing and setting up my Pi and Satnogs client, I can schedule an observation successfully. When it comes time for the observation to run - it appears that little happens and that no observation is made.
What I Have Done
- Reinstalled image from scratch
- Tried another RPi
- Ensured that Raspbian is up to date
- Ensured that satnogs-config is updated
- Installed Satnogs Monitor - I can see the jobs come up, but when the job should be active there is no waterfall or activity
- rtl_test is successful
- /tmp/.satnogs/data temporarily has the ‘receiving_waterfall…dat’ file of 0 size
- /tmp/.satnogs/data/incomplete is empty
- Installed SoapySDR and attempted a connection with CubicSDR on Win (crashes)
- There are some kernel mismatch errors, but after investigating these appear unrelated and of no concern (common in current Raspbian)
- APPLY - Interestingly, the Apply function ALWAYS stalls and I must Ctrl-C (this occurred on both Pi’s and with different installs) - This happens on 'Download UHD images…
systemctl status satnogs-client
pi@RPi1683:/tmp/.satnogs/data $ systemctl status satnogs-client
