I corrected the receive frequency to 436.7485 and after that Doppler correction did the rest. Seems that we are getting somewhere. But after this weekend I am careful.

Here is part of the data that I received, the rest can be found at the download location. In total I received 44 frames.

Sorry for all the possible confusion. I have to go back to the drawing board because what seemed to be a good fit last night, isn’t working anymore. It is still not clear what TLE to be used with CUSat and DANDE.
