Hi Roy!
I use Orbitron on Windows and the best I can do there is one refresh per second.
I've not tried FoxTelem w/ HuskySat-1 on linux, but the nice thing about GPredict is that you can get smoother doppler adjustments by using a shorter update interval. I use 1/2 second for doppler tracking w/ GPredict most of the time.
I guess use what is producing the best result for you, but I've never noticed that the update interval was a critical factor with various telemetry decoding efforts. Much more impactful with HuskySat-1's BPSK signal is to keep that audio output centered around the 1500 Hz mark. Fine-tuning your signal during a pass to keep it as close to center as possible in your 3k passband will produce best results, I think.

What are all all the computer controlled stations using for doppler adjust interval? I had previously tried 100ms, and was getting about 45 frames per decent pass. I just had a 50deg pass and increased the interval to 500ms, and got almost 70 frames. I wonder if there is a sweet spot?
