Regarding Observation 14973564 …
@fredy It looks like you marked this observation as having a good reception report. I am trying to tune my ground station still and I’m not sure how this one worked but it doesn’t have any visible signal on the waterfall.
This is the automatic guess when there is a frame uploaded for specific modulations in observation.
You can see the vettings of the waterfall (currently the only artifact we vet) if you click on the square next to the info button above the waterfall.
As you noted there isn’t any signal in waterfall, so I vet it as “without signal”.
The frame is a noise frame, in other words noise that passed the demodulation process. This is not something rare, it happens depending on the modulation parameters.
