I was about to mention it as well.
I thought the problem could be solved by displaying the value in degrees somewhere on the X screen.
For example, when you're engaging a jamming target with the SA-5, you have to adjust the altitude gauge with a control on a different screen. While this is very annoying I think the altitude gauge is in the correct place. It wouldn't make much sense if it were located anywhere else, same for adjusting the Square Pair elevation, the elevation indicator wouldn't really "fit in" any place else. However, being able to move the radar without having to even be on the same screen would eliminate this problem entirely.
