Regarding Observation 2230340 …
This looks really strange to me. It seems to alternate between two different “modes” with different noise level? Also, doppler correction curves are usually very smooth arches, but here the doppler correction looks like a straight line.
Any idea why this happens?
@surligas ^^ reminds you of something?
The issue is tracked at https://gitlab.com/librespacefoundation/satnogs/satnogs-client/-/issues/354
I have reported the way to reproduce it and the possible cause. If I recall well, the only way to recover from it is to restart the client.
Should I downgrade my station until a fix is available? If so, to what version and how do I perform a downgrade?
Or should I stop satnogs-client.service until a fix is available?
I don’t think it’s even possible to perform a downgrade of a current install right now, especially with the move from GNURadio 3.7 to 3.8. I’ve asked this question before and been met with only silence.
It may be possible to grab a much older image (possibly this one from 2019: https://gitlab.com/librespacefoundation/satnogs/satnogs-pi-gen/builds/artifacts/2019091100/raw/deploy/image_2019-09-11-Raspbian-SatNOGS-lite.zip?job=release ).
However, I’m not sure the image comes with all the required dependencies, and an upgrade will immediately bring in the latest versions of everything unless the git repos are set to a specific tag. I’m not sure how to do this, or what tag to use…
And yes, it looks like the doppler correction isn’t running correctly in that waterfall. It sucks that there isn’t an obvious solution to this, and that there isn’t an easy way to downgrade.
https://network.satnogs.org/observations/2247583/ managed to get a decodable packet, but the observation is a mess. So are most of the observations from my station.
