Two other points. There is a 1200 Hz error on CAS-4A....a few hundred Hz is predictable, but I think an additional 1000 Hz may have crept in there, so check your calcs.
Notice all others are no more than a few hundred Hz...which is as it should be.
The reference freq are for USB, perfect voice tone and fully doppler corrected. The Rx are FunCube Pro+ SDRs, that have been calibrated to within 0.356 Hz @ 10 MHz and checked against 6 meters to be accurate within 3 Hz. (Compared to GPS Discipline Oscillator)

Hi Folks,
With the number of Linear Transponder Satellites that are operational or in the pipeline, I thought a simple program to convert uplink to downlink frequencies was worth writing. I’ve written one for Windows. You can find it here: https://www.dropbox.com/sh/4o375h6bygjxkzr/AABi9Ck9Wc6ODrhXwIVHxI-_a?dl=0 I’ve put the exe file and the same file in zip format. I have put all the current birds plus the ones that have launches pending. Just select the satellite of interest from the “Satellite” drop down menu, put your frequency into the text box and hit the Up or Dn calculate button.
Let me know if you think this is useful.
