My True South Satellite?

[PilotS77]

Great to find a forum for FTA!

I am having the hardest time installing my system

I will try your suggestions - however what is USALS?

My setup is a Microyal MRX-900 and I do have an SG2100 motorized system.

My Latitude is 38.84 N and my Long is 94.66 W, so if I understand correctly I should point to Galaxy 3C?

Any assistance greatly appreciated! I am very very new at all this.

Well here are some more questions since I had some time to play with my setup this morning.

If I understand correctly Galaxy 3C is my true south satellite for Long. 94.6.

My declination is -3.7, so do I point my motorized dish to 176.3 (my true South if I am correct) or 181.6 where Galaxy 3C should be?

I do get almost always signal strength - never below 45 but no quality.

Here are the settings in the receiver:

LNB Type: Normal
LNB Freq. 1: 5150
LNG Freq. 2: 10750

22K Hz Tone: None

Pointing to where I think it is True South I get Strength 57 and Quality 0

If I change LNB Type here is what I get:

LNB Type: Universal
LNB Freq. 1: 9750
LNG Freq. 2: 10600

22K Hz Tone: None

Pointing to where I think it is True South I get Strength 45 and Quality 0

Any help would be appreciated - specially if I have understood something wrong!

Thanks

Hello and welcome to the SatelliteGuys.US FTA forum!

Your receiver does not have USALS, lots of other receivers have it, and it REALLY helps find all the satellites after you have found your true south. (Yes G3C is your T/South sat.)

http://www.usals.info/inglese/home.htm

Your Motor elevation should be at 51 deg.
And dish elevation at 24 deg.

You need to find out what kind of LNBF you have, your first example was for C band that will never work. (Any markings on the LNBF?)

Standard LNBF L.O. 10750
Universal LNBF L.O. 09750-19600

To find G3C I use the below coordinates.....

CCTV-9

11780 Freq.
H Polarity
20760 S/R

Here are some pictures of my set up - any ideas?

Do I point the dish to True South or the True South Satellite?

Is there a trick to the pointing?

Thanks again!

John

True south satellite, its positioned at your true south.

Man those pictures are BIG : )

I see a problem right away in the 2nd picture your mast is not level, this is the part that the motor is clamped to, use a level and put it on top. If this is off NOTHING will work.

If you get stuck remove the motor, find the satellite and work your way back.

 

[PilotS77]

So I point it to 181 and not 176? I

That can make a huge difference!!!!

Actually the post is level - the photographer was not!

Thank you for sticking with moe on this -

Magnetic south is at 180 deg. on a compass
True south is 180 deg. +/- your magnetic deviation in your area of the country.
Set your compass to 180 deg. then subtract 4 deg. dont move the compass just look at 176 deg. and thats where the satellite will be!
But thats really just to get you close to the satellite, you will need to use the TV and the Quality meter .

So I will set the disk tp pont at 176 - but calculations tell me that the satelite is at 181, what am I missing?

In any case, I set the dish to 176 and then a rotate the whole assembly right or left and just see what it does to the signal?

I must be missing somthing basic here.

Thanks

Have a look these....

[PilotS77]

These are very good thank you!

You have done this many times so it must feel very simple to you - so forgive my instance, as you obsereved in the pictures I think that my settings are correct, my question is do I point the whole assemby towards 176 and that is where G3C should be?

Then if I fine tune that sat the rest should be failrly easy to find?

Again thank you for your patience.

John

 

[PSB]

You have got it! The motor should be at zero and point everything true south (174deg.) at G3C.
The other satellites can be found using DiSEqC 1.2
(enter coordinates/motor over until you see signal quality/store position)
Lets stick to finding true south first, if no luck remove the motor and find the satellite with just the dish/LNBF.

 

[PilotS77]

I plan to try Monday and see if I can poin it to 176 and get something!

Now here is my setup:

A Microyal MRX-900 Receiver
A Winegard dish
An SG-2100 motor

Please give me some feedback on the equipment.

I am also including soem additional pictures of my install - here is my problem on most everything that I have read to point the dish one must be behiind it - not possible with my install any advise?

Again thank you for the pateince and help!

Should be plenty of room to get to everything from where it is. I would have kept the dish lower, unless you have "line of sight" Issues, or kids.
Nice pictures!

 

[PilotS77]

Weather not co-operating today but I did spend 45 minutes - no results!

The mast is level - rechecked it all looks good.

I am pointing to where 176 should be and scanning - nothing!

Now another question: the settings you provided are different than the ones in the receiver - I used both. For oyur settings I get a stonger singla strength but the scan is almost instant; when I use the build in settings I get a lower singal strength but the serach takes up to 4 minutes. Hope the picture help, also maybe you will see something that I am doing wrong!

Again thank you so much - I am learning and having fun!

Don't use the one in the right picture. Those are C-band (C-Band is 4 digit frequency...KU is 5 digit)

Use 11780 H 20760 as your option. The thing with a Microyal is its REAL sensitive with the frequency...if its off by one or two it won't work. I think PSB gave the wrong Symbol Rate

Also, is your LNBF universal or Standard? If its standard, the LO frequency should be 10750 for both. If its universal, the 22K setting needs to be set to on.

 

[Mr Tony]

also, once you get the frequency in there and such, don't scan it...
try and move the dish a little bit to see if the bottom bar will turn yellow (telling you that there is a good signal)

 

[Mr Tony]

something isn't setup right

The bottom bar (quality) should be jumping around and grey (no signal) or yellow (good signal). With it at 0, something isn't set right

 

[PilotS77]

My LNB is a standard one

Model ASC321S DMS International Digital KU Band LNBF

The options available are LNBF, Normal, or Universal - what should I choose?

Thanks

John

 

[Mr Tony]

normal

and then change BOTH LO frequencies to 10750/10750

So even if you are on the right satellite, the settings right now made it not work.

 

[PilotS77]

A ray of hope! I god an orange strength and quality movement for a second as the motor was moving the dish - lasted for a millisecond!

So Now I try to point as close to 176 and Galaxy 3C should be there, correct?

Thank you for all your help!
