Thanks.
Making a map of the arc is brilliant idea. I will try to do it in two weeks, weather will be cooler a bit.
I want to push up and down (strictly vertically) the whole dish assembly, as I understand, without untightening any bolts, for all the important for me satellites:
79 (east-most), 87, 97, 121 (south), 123, 129, 148(not important, but west-most).
If the signal improves for any of them while moving up/down, I will mark it on my map with up/down arrows. Then, will analize
the results.

Back to the topic: I saw specs for
Moteck SG2100, looks like that one gives more travel in each direction:
75˚EAST ~ 75˚WEST.
But I am happy with the Satcontrol so far, even without getting eastern sats.
