Observation 7508483: TIMATION-II (4256) - Help needed to understand if this is a sat

Regarding Observation 7508483

Hi Community,
can you help me out understand if I captured a signal here?
Looking at other captures from this sat mine looks different but I am not sure.

From the description I understand this should be morse code - and on the audio this sounds like morse to me.
Also I think we can see one terrestrial signal on the left hand side, which “bends” due to the doppler shift compensation.
The signal in the center seems straight to me, which would indicate to me it is not terrestrial.
But then I am confused that there are more than one straight lines from other sources? Probably not all sats?

Maybe you can help me understand what is going on here.
