Hello Bali,
The SSDV decoder is in this repository: Files · master-f4tnk-v3.1 · f4tnk / gr-satnogs · GitLab . Search for it using the keyword “ssdv”.
Then you need a flowgraph compatible with h=2: generic/fsk.grc · master-f4tnk-v2.2c · f4tnk / satnogs-flowgraphs · GitLab
And a compatible Satnogs client, like this one: satnogsclient · master-f4tnk-v2.1 · f4tnk / satnogs-client-librespace · GitLab
I want to emphasize that this is very experimental and not yet validated, as I haven’t received enough frames for the same image.
It’s not trivial to set up

2026-06-07 18:16SatNOGS Network - Observation 14250720
With the update to satnogs-flowgraphs-2.5.2, my SatNOGS ground station is now able to record audio that can be decoded later. This is a very welcome improvement, as it allows me to conveniently analyze observations made during weekdays and late at night when I am unable to monitor passes in real time.
The image I recovered has an ID of 000. Does this indicate that the image was retransmitted?

i’m wondering why hades-sa signal is not stable as silversat for example. is it caused by the pocket sat tumbling?

On the HADES-SA (SpinnyONE) satellite, SSDV Image ID 0 is a pre-loaded commemorative mission plaque stored in the satellite’s Flash memory

Obviously the preloaded image #000 has been overwritten. Here is the original image as it was received in Greece a few minutes after the deployment of the satellite Transporter-16 Rideshare: VSFB SLC-4E : 2026-03-30 11:02 UTC - #72 by sv2hwm @PY4ZBZ ,
