Observation 20907: NOAA 19 [dev network]

Hey,

I have a weird observation
https://network-dev.satnogs.org/observations/20909/

I do not recognise the normal waterfall of NOAA APT signals.
Does my RTLSDR has been saturated by a more powerfull emission?
How can I classify this observation?

73,

The observation was done on the telemetry beacon frequency. You need to select the APT channel.

I think the observation is good because you can clearly see something coming from the satellite (the vertical lines around 0 Hz). We just can’t make any sense out of them.

OK, sorry, my finger slipped.
Thank you!
