After updating the ST16 and Typhoon H with the March 2017 update I have the same problems of pixelated, jumpy frames, and smeared images that everyone else on this thread has had.
It is pretty obvious that the cause of this is the coding in the March update, it's not a hardware problem that suddenly broke after the March update.
The reason it is necessary to have an honest and accurate video recording by the ST16 of what it has received is to determine when and under what conditions the video link becomes corrupted (out of range or obscured).
If the ST16 software doesn't faithfully record the video link it's not possible to determine if or when the actual video link was corrupted, or if it was corrupted at all.
As it stands now the ST16 video recording is useless as it shows the video link is corrupted with the Typhoon sitting on the ground 20' away from the ST16.
hmmm, the previous message didn't show up as being posted until I posted this one, after all this typing I'll leave both up.
