I have been experimenting with AO-92 as from its launch. Some observations:
1) The fading on this bird seems to be high and quite unpredictable, requires a lot of changes of polarization to keep the Rx signal to an adequate level.
2) Seems that the fading is both on the U/V and L-mode, more seems to me that the uplink is more affected.
3) Telemetry seems to be quite reliable with FoxTelem in all modes.
Today, it was even worse losing the bird many times during the pass, it seems that it is degrading quite quickly, hope that this is not the case.
Just to share my observation.
