Observation 3209350: TTU100 (46312)

Regarding Observation 3209350

I don’t know why when an observation is kept for TTU100 there is no waterfall or audio decode just .out and .dat files (see attached image)

Please let me know why

Hi @vu2yq,

Could you check the size of these .dat and .out files, by running ls -la?

Also, I’m not sure about the error you get and if this is related with the issue of the produced files. Could you check the logs to see if there are other kind of errors, by running journalctl -u satnogs-client.service (use q for quitting)?

I will provide you the logs shortly… I had restarted the devicebut had taken screenshots before restart.

Also, FYI: I have moved the .satnogs/data folder to /home/pi location (with 777 permissions set to folder). This folder change was done few days back and it has worked okay so far.

EDIT: The logs for above files is provided in my second post above

Station was working fine when I was using a older generic RTL SDR dongle. Recently (3-4 days back)
I changed the dongle to Nooelec NESDR Smart RTL -SDR dongle. Results with UHF band on this dongle are good compared to older dongles.

There was pass of NO-84 at 08:14UTC today and here is the log

hm… that’s strange… we need to investigate this more. Please open an issue at https://gitlab.com/librespacefoundation/satnogs/satnogs-client/-/issues with all the details and the logs. Thank you!

vu2yq · November 28, 2020, 3:09pm

Issue is created with logs of two observations captured today (28th Nov). Let me know if more info is needed

Hello @fredy

To try out another approach I tried following things:

On a new memory card installed the Satnogs Raspi Image
As mentioned in the article https://wiki.satnogs.org/Omnidirectional_Station_How_To I updated the Satnogs client before using it.
Despite this I faced same issue wherein the observations would fail. Only one observation was successful, rest failed with similar issue mentioned above
There was one file which was shown as not found (I will share the details of that file shortly), after searching for similar articles I found an thread which suggested below steps:
Run sudo satnogs upgrade followed by Applying the changes through satnogs setup.
All this while the Nooelec NESDR dongle was connected. Finally did a system reboot
After almost 24+ hours I haven’t faced any issue with observation… all observations were successfully recorded… (check my observations log)

I will keep you posted if I see any issues
