I have notice the same thing here, but use the amateur.txt instead nasa.all and nasabare.txt, that improves a lot, maybe is just that the source is not updated as often as the amateur.txt

That being said, double check time sync and qth location just in case.

Try it and let us know if you notice the same improvement as I.

Subject: [AMSAT-BB] ISS Dopplers Still Off

So… using nasabare for 7/2 didn’t help. The ISS was still about 10kHz above where SatPC32 was tuning the IC 9700. Had to enable the VFO and manually tune up to it and then follow it back down the band. Also still getting good signals after supposed LOS, down to -5 to -8 degrees. Had SatSat in front of me on the iPad watching the ISS az, el, range, altitude and Doppler at 100MHz, AOS/LOS times. It was all very close to what SatPC32 was displaying. Yet SatPC32 did not put the rig where the ISS links were. Only seems to affect ISS as far as I can tell. I really don’t get it.
