Get multiple satellite, SG2100 moter. Help Please

[flybird74]

I was able to get AMC3, G11, G3C, T5, T6,G4R and AMC4. But my problem is this. The signal strenth are strong on G3C, 81%, OK on T5 and
T6 50-61%, week on AMC 3 and AMC4 50% or less.

How do I adjust my dish and polarization so that I can get better signals from AMC3 and AMC4 without losing much on other satellite?

I started from AMC3, and was able to get signal strenth to about 71%. Then I adjusted my dish so that the signal strenth are strong on G3C, after I got better signals from G3C, AMC3 signals are now week. It seems I can never get it right by taking this approach. Your advice is highly appreciated.

Also, with sg2100, upto how many satellite can you get?

What sat is your true south? Did you aim your dish at the true south sat first? How big is your dish? It seems like you did not aim your dish at true south first, therefor the dish does not track the arc correctly.

In addition to dt's comments, make sure that your mounting pole is perfectly vertical. Use your angle meter or level not only on the top, but the sides and all the way around. Even if your only off 2 deg from vert it is enough to affect the tracking of the arc.

I have a 30'' dish from, my location longitude is 81.3, latitude 28.8.
So what Satellite is my true south? Also, if we get things right, so the
dish is able to follow the arc, what signal strenth should we expect on
these sat? Since some sat singls are strong, some are not.

one more comments. Even you can get the mast to be 100% v,
once you mount your motor and dish, it will not be 100% vert.

This is true. It is designed intentionally that way to compensate for LNB rotation as the dish moves. When using a motor the LNB must be mounted straight down -- 0 % polarity compensation.

Lat 81.3 deg your tru south sat would be nimiq 2 at 82 deg. However nimiq 2 is a circular polarization satellite and you probably wouldn't be able to get a lock with a regular LNB. The next best satellite to align to would be AMC5 at 79 deg. On AMC5 try 11742V, symbol rate 11110 and a fec of 3/4. This is the utah education mux and comes in strong. You get weak sigs and strong sigs because all sats are different. Some of the DBS satellites, direct tv, echostar ect are very strong (120W) because the receive dish's are only 18" dia. In addition it varies from transponder to transponder. If your tuned into a dsng feed it will probably be a lot weaker because the receive site is using a huge dish and they don't need to run so much power. Some sats only run 25W and on your meter thats a big difference. In addition your pole will still be vertical once the dish is installed. (the dish won't be vertical of course but your mounting pole for the dish/motor will be) If the pole moves when you mount the dish then your mount is not secure enough. The mount is designed to support the weight of the dish (and motor). If this wasn't the case then nobody would be able to track the arc once the dish is mounted. After you mount the dish use your level again around the pole and it should still be vertical, if not then retighten the bolts/screws on the mount or you will have to find something more sturdy to mount the dish on.

what the command synch means on the receiver menu when using a Disecq 1.2 motor. what Diseqc 1.3 means? how can a fortec star receiver and sg 2010 used using the usals feature?
Thanks

Diseqc 1.3 is the USALS feature.

One thing I want to add is that there are 2 deg apart between 81W (truesouth) and 79W (AMC5). So the h-h mount is not set at 0 for when tuning the AMC5.
There are 2 ways to compensate the 2 deg differences:
1. Use USALS feature to move the dish to AMC5. Make sure LONG and LAT are keyed in correctly.
2. Use Diseqc 1.2 to move the dish manually towards the EAST. 2 deg is pretty small, perhaps 1 click is enough. Then check the mount rotation indicator to make is the mount parks at 2 degs from the center (0 deg).

After reading the installation guide from the link you provided. It is still not clear to me as how do determine my true south.

My location is: L 28.75 Longt 81.34. So if you are facing magnetic south,
do you move 2 degrees to the east to get true south??

sorry. forget my previous msg. I did not notice there were 3 pages.
