36" dish

On the Motor Bracket, does it list Elevation or Latitude?

Part of the problem as I see it is that elevation means different things to different people. On the website I just gave you elevation means (90 degrees minus latitude) minus declination. Other people say elevation is just 90 degrees minus latitude. There is no way possible to communicate if the communicators can't agree on the meanings of the words being used!

My above comment pertains to your true south satellite. (Motorized systems are trickier)

look @ these pics.

HH90​

Distance: 37692km
Motor Latitude: 42.3°
Declination Angle: 6.5°
Dish Elevation: 38°
Azimuth (true): 180.0°
Azimuth (magn.): 187.4°"
This c/p is from dish pointer site.

You should adjust this to your latitude. That will make the motor's axis parallel to the earth's axis.

The scale in the pictures is set up so you set it to your latitude. Notice that if you were at zero latitude (at the equator) the motor would be at a very high angle and that if you were at the north pole the motor would be at level to the ground, a low angle. This makes sense.

 

[rogerduncan100]

Once you get the motor angle right you then adjust the dish angle (declination) to that it aims at the satellite which is about five earth radii away and above the equator. If the distance to the satellite was infinite the declination would be zero but because the distance is about five earth radii there must be a 6.5 degree declination angle.

How can you be doing this stuff in this bitter cold?? You are braver than I!

Maybe this pic shows my motor seting

That was yesterday. weather was a bit mild. now is cold.
i just want to test the motor for working condition and my new s9.

Your picture looks like you have it (the Latitude) set to about 43.
One other thing to check is that the top of the metal bracket is level and is not being pulled down due to the weight of the motor and dish.

 

[lme]

It is set to 42.3 as per dishpointer.
I have to wait for spring for more investigations.

 

[rogerduncan100]

That's wise. It's %&@*!%^ cold!

And another dumping of snow due!!!

Once you get the motor angle right you then adjust the dish angle (declination) to that it aims at the satellite which is about five earth radii away and above the equator. If the distance to the satellite was infinite the declination would be zero but because the distance is about five earth radii there must be a 6.5 degree declination angle.

So, where should I count the 6.5° declination: to the dish or the motor ?
(To the motor latitude scale makes sense for me in oder to bring its axis parallel to the earth!)

That is accounted in the Dish Elevation, so just set the Dish to the recommended Elevation for you location and motor.

Motor Latitude: 42.3°
Dish Elevation: 38°
Azimuth (magn.): 187.5° (compass)

Motor Latitude: 42.3°
Dish Elevation: 38°
Elevation: 41.2°
Azimuth (magn.): 187.5° (compass)

What is "Elevation:41.2°" for, if the dish elevation is already set @ 38°?
