Regarding Observation 12430312 …
I want to understand what the lines in the waterfall plot mean i see there is noise and interference but how are the horizontal green line different from the horizontal black lines? I am stuck on analysing the plots
These lines are “man made noise” picked up by your antenna but no part of the Oscar 7 transmission. A valid observation to compare with is SatNOGS Network - Observation 12470745
If possible, try to run same SDR on SDR software and view in realtime what’s transmitting. Might be adjusting the gain a bit lower solves this.
