Yes that is where i always start 0.8w
Reset you motor before setting up again, as if starting from new again.
Motor should then be driven to 0.8w (some motors have digital displays on the actual motor - i am not sure about your one? )
Fine tune for best signal on 0.8w on both H and V transponders try channel U tv (12687 H 27500) and channel Al Jazeera English (12418 V 28000) both are free channels.
Then drive motor to 30west and check for signal ,then to 39 east, and check for signal.
If there is no signal at 30w or 39e then bend dish face up or down to try for signal, that will tell you which way to adjust the motor latitude.
Go back to 0.8 west and check for signal. If signal is reduced, fine tune parabolic (dish face) elevation.
Repeat this process several times, between all 3 satellites' until you have good signal on all 3.
When you do, then you should have good signal everywhere, the full satellite arc.
