Had a blast collecting telemetry for MaSat-1 just now. I used object C, which was not correct for doppler. Judging by the point at which the signal ended on my clear horizon, I think it might be F or G.
For those who are new to the software, I'd note that the strongest signal on the waterfall is the one that should be aligned approximately with the 575 Hz mark. It is quite tolerant of your being off by a 100 Hz or so, I'd say. I also think that the CW signal should be on the 1200 Hz mark (i.e., don't tune the CW to a typical CW tone, which is around 600 Hz).
Does anyone know how close to the upper and lower marks I can set my filter on the TS-2000?

I just tried F and G. G was the better fit, with a 80+ deg. pass, it held up pretty well against the doppler, though not perfectly.
