Regarding Observation 373481 …
Is this another satellite crossing path with Range A?
It looks like a terrestrial signal. You can say that from the curve and also that there is a similar curve at ~+15KHz which has the same shape.
cool thanks @fredy, I’ll do the ppm and see how I go.
I thought it may have not been the TLE i was looking for because of the Doppler shift.
I’ll waterproof this node, set the ppm and take it out of test.
