Hi Mate,
I went on this project last week too...I had many questions that have become a lot more clearer now.
Go to...
Satellite Finder / Dish Pointing Calculator with Google Maps | DishPointer.com
I see that you are also using the technomate motor...
After putting in your location...select the motor 'MOTECK SG2100' from the list of satellites. This will give you line of site for true south (0 degrees). The technomate motor is the 'MOTECK SG2100' but has a its own branding and casing.
For example... I have selected leicester and 'MOTECK SG2100' on the above site.. Details i get back are below. (This is the block of text below the map towards the right)
Latitude: 52.6346°
Longitude: -1.1294°
Motor Latitude: 52.6°
Declination Angle: 7.5°
Dish Elevation: 22°
Elevation: 29.8°
Azimuth (true): 180.0°
Azimuth (magn.): 182.3°
From this information what i did...(Before i hung up the dish - all adjustments done at ground level)
1. Set motor Latitude angle to 52.6° - Well as close as.
2. The angle on the dish needs to be 22° as above mentioned Dish Elevation. (All the detail should be in the manual - I got confused here because i have read many articles on the setup. The motor arm comes off at 30° from the motor it self. So the 22° is derived from 30 - Declination angle = 22° or there about)
3. When attaching the motor make sure it is set to 0, and that when attaching to dish and all that everything alligns in a straight line. As in LNB in line with the 0 from the motor marking
No need to worry about Azimuth (true), Azimuth (magn.) or LNB skew angles. I didnt and it worked great.
Now...As you say you have the pole plum level. This is a must otherwise you will start to miss satellites on the complete Arc. (A meter also would be extremely handy because this can be difficult - The angle can be very exegerated once it reaches the satellite lol)
Ok...So once plum...hang the dish...Semi tighten bolts on the pole so that you can freely move it.
Point to south or as best possible south.
On the reciever got to USALS config (Motor config) and set your long and latitude... for the above example it would be Latitude 52.6 North and Longitude 1.1294 West.
Once that is set...its all about playing around, moving the whole dish around till you hit the satellite at 0.8 W Thor.
From there you will need to move around the arc scanning the satellites as you require.
Hope any of this is off help.
Regards.
