Observation 6360913: Astrocast 0.2 (44083)

Regarding Observation 6360913 … There is a clear signal, not following the Doppler curves for terrestrial noise, but it also doesn’t seem to belong to this satellite? A different moving object? I looked through the sat, flying over the GS at that time and none of them was close enough in frequency, the closest one was 75kHz away
