I notice that the frequency calculated by MacDoppler is slightly off from the frequency that I hear the telemetry at. It's off by up to half a kHz. It's not a fixed offset (as I would expect if my Radio was not calibrated on the right frequency), so I can't just offset the frequency slightly in the software.
Is this expected (within experimental error), or is likely that I have something wrong with my setup? It's hard to tell if I have the same offset for other satellites, because a CW beacon is present even if the tuning is off just slightly. When using a radio to receive AO-73 (vs the dongle) the tuning needs to be quite accurate. 73 Chris ac2cz -- Chris E.
