I don’t think that MCubed-2 is Object A or C.

Objects J, K and L are very close – there is an offset of max. 1 KHz between J and K.
We think the MCubed-2 is not transmitting on her nominal frequency 437.485 MHz. We see an offset of -5 .. -7 KHz. So it’s very hard to say which TLE suits better. I am going with object J and correct the offset.
