Help with motorised setup

Vu+ Newbie
Hi Guys
I have just put up a 90 dish and motor attached to my VU+Duo2.
I followed the instructions on installation to the letter.
Put the wall bracket up and squared it with a spirt level, attached motor and set at due South then set the Latitude to 52.5 then attached the dish also set inline with the motor at due south (used a compass app on my iPad).
Set elevation to 29.8 (30 is near enough).
set find sat to Thor 0.8w , at these setting cannot find thor at i degree west unless I bring the dish down to 24 degrees then got another couple of sats to the east but not much.
put dish back to 30 degrees at zero (due south) so see what i could find.
i get
19.2e with SNR 71% and AGC at 79%
20.0e with SNR 74% and AGC at 79%
23.3e with SNR 62% and AGC at 84%
23.5e with SNR 68% and AGC at 84%
25.5e with SNR 38% and AGC at 79%
28.2e with SNR 76% and AGC at 79%
30.5e with SNR 37% and AGC at 79%

any ideas would be helpful and much appreciated

Hi
The elevation will depend on where you are - North - Central - South. Set Thor @ .8W then Astra @ 28.2E and finally Hispasat @ 30W. The rest should fall in line if you have the mounting mast 100% vertical and no trees etc in the way. Better to use a proper compass rather than a mobile phone. In multi-sat nothing is near enough, its spot on or not. If not you will miss out on a lot of weak sats. I have been installing multi sat for over 25 years. If done properly the first time it will save you lots of time in the future, believe me. If you have set up properly you should get 28.2E, 26E, 25.5E, 23.5E, 21.6E, 19.2E, 17E, 16E, 13E, 10E, 9E, 7E, 4.8E, 3.1E .08W, 4W, 5W, 7W, 8W, 11W, 12.5W, 15W, 18W, 22W, 24.5W, 27.5W and 30W. You may get more or less dependent on where you are. You will not find much on 18W & 27.5W but the rest there is plenty to see. I currently have approx. 10,000 channels!!
Good luck and have a good Christmas period.
 
It seems to me that you did not take into account the angle of the dish antenna
in relation to your motor.
Read once more manual for your motor.
 
You can use this very good site

http://www.dishpointer.com/

View the motorized systems
Perhaps there is your motor.

Example Stab HH120

0 sat for you location is i think 0.8 W

Dish Setup Data View dish alignment line in Google Earth
Latitude: 52.4°
Longitude: -1.4°
Name: Stab HH120
Distance: 38614km
Motor Latitude: 52.5°
Declination Angle: 7.5°
Dish Elevation: 22°

Of course this is valid only for STAB HH120
But read Manual to be sure.

And do not forget each millimeter is important
as well as the position of the LNB

Hi Guys many thanks for your input its much appreciated.
I did use the latitude and dish settings from dish pointer.com and my setting above are from there.
been doing some more searching and found that when you set everything to south I then input thor into sat finder (1degree west) and moved to it with the motor, then tried fine tuning by moving the motor and dish, first mistake,
I read you set eveythig to south then fine tune to find Thor (1 degree south) by moving motor and dish by hand not using receiver and motor.
The motor I am using is a Amiko DM 3800 not sure if this is a good one or not.
do it matter where along the motor shaft you put the dish on, in my mind i thinking that the lower you are the lbigger the arc and higher smaller arc (how important is this)?

best regards

Thats exactly how I set mine up.....dont think it matters position on motor shaft..mine is central...
