There are several ways that you can get the dish settings.
1) At home, go into the sat settings screen and enter your zip ans dish type, as you enter them you will see the settings for the dish alignment.
2) you can go dishpointer.com, enter your zip code and again the dish type, this will give you the settings.
Now, using your readings for home, when you go on the road, set up dish the exect same way, then, if you traveled east from home, move the dish right JUST A HAIR AT A TIME, waiting a minute between adjustments and do only one movement at a time.
After you have obtained a lock, write these settings down for that location.
As a rule, you can travel about 200 miles in any direction and only have to move your settings by less then a couple of degrees from your base settings.
Go to dishpointer.com enter your location and then select the DTV 101 satellite click go and get your settings.
