Trouble with my new installation Dish 33 inch + SG2100

[regisma]

Hi,

I have installed my Fortec Star 80 centimeters Dish with a SG2100 motor.

My Latitude is 45.5 N and my Longitude is 73.8 W (Montreal, Canada)

I have set the Elevation angle of the motor to 45 degree and figured out in the SG2100 user manual that the Declinaison Angle of the dish to be 23.2 degree.

Then I have ensured that the motor is set to 0 degree and tried to align the dish to my True South (Magnetic South +16 Degree).

Then I have set my Longitude and my Latitude in My Digiwave Diamond through the Motor settings and specified USALS.

Then I have asked the IRD to point to AMC 6 (71.8W) so around 177.2 in my Azimuth.

I was able to just have a signal between 53 % to 67 % and a rough Quality of less than 10%.

Would it be easier to find a Satellite such Estrela do Sul1 at 61.5W that correspond to 180?

Does My LNB is damaged?

Note I have tried to ensure that my Mast is perfectly vertical.

thanks

Make sure the LNBF is straight up and down for your true south satellite and set it as far back from the dish/reflector as it can go in the holder.

(SBS6) 74w I would use this satellite (ONN)

Your motor angles are good. And very rarely do you get a bad LNBF, it happens but not a lot. If all else fails remove the motor and see what quality you get with a fixed dish. If anything a motorized dish should give you better quality than a fixed dish as the whole dish skews as it follows the arc.

Sounds like to me that possibly you need to recheck your LNB LO settings and that you afre serching for a live transponder and symbol rate.

Hi,

Here are the info related to this LNB, do I need to change something in my receiver?

thanks

HIGH BAND SELECTION

OPERATING TEMPERATURE -40 ~ +60

-------------------------------------------------------------
NOTE: This what I see on the LNB:

RF: 11.70/12.20GHz
IF 950/1450 MHz
LO: 10.750GHz
Gain 5.5 db
Noise 0.5 db
-------------------------------------------------------------

The menu should be very close to the CoolSat 4000 Pro.

Dish Setting:
- Satellite: AMC 6
- LNB Power: (On / Off / 13V / 18 V) is at ON presently
- LNB Type: (Single / Universal / OCS ) is at Universal
- LNB Freq. : ?????
- 22KHz: (ON / OFF) Presently already set to ON
- DISEqC : (OFF / 1.0 / 1.1) Presently set to OFF, I have not install it yet

Motorized Settings:
- Satellite: AMC 6
- LNB Power: (On / Off / 13V / 18 V) is at ON presently
- LNB Type: (Single / Universal / OCS ) is at Universal
- LNB Freq. : ?????
- DISEqC Motor: (OFF / 1.2 / USALS) is at USALS
- Move: (<< East / Stop / West >>) now it show Stop
- Limit: Disable
- Antenna Position:
-- Sat Degree: 72.0W
-- Antenna Longitude: 073.8 W
-- Antenna Latitude: 045.5 N

vLooks like a Universial LNB

I do not have one but I think you have provided enough infor for some others on here to set you up with the right info.

I would guess on your receiver you want to choose Universial for LNB Type, 10600 and 9500 for you LNB Freq.

I think,

Watch out about the elevation angle on the Fortec dish. The scale on the dish isn't all that accurate. I think mine was somewhere around 6 to 8 degrees off. You might try peaking your dish like you did before and got 10% quality, and then try making small adjustments on the elevation of the dish.

Hi,

Thanks a lot for the warning.
