2 weeks passed, got nothing, need your help

[FTA001]

Bought M-2 Motorized DYNAMIC Satellite Choice Set with the following components:

90N Fortec dish
Sadoun PowerTech DG280B HH Motor
QPH031 Quad LNBF
SM21H 22KHz switch

Tried another week, still cannot get any signal. The “signal level” is always under 4%, the same level as no cable connected. We tried all possible ways trying to get any signals but nothing. We switched a little each time within the possible directions and also changed angle a little each time but nowhere to get signal. We even hold dish by hands, and move-stop and move-stop scanning the sky but no signal found. We think there are two possible reasons:

1. We didn’t connect the LNB (there are four outputs, L1 C1 L2 C2) correctly:
Our cable connection is totally like this connection (the same LNB as ours): http://www.sadoun.com/Sat/Products/Invacom/invacom-qph-031-7.JPG, L1 and C2 are used. But on the installation configuration diagrams, http://www.sadoun.com/Sat/Products/Invacom/Invacom-lnb-b.gif
, we cannot found a match one. There are four different configuration, we simply don’t know which one we should follow.

Our switch is this one, http://www.sadoun.com/Sat/Products/S/S-SM21H-2-way-switch.htm . We don’t know how to connect the LNB to this switch. Anybody can help us?

2. The LNB is broken and cannot get signal or transfer signal to the receiver. How can tell if the LNB is working or not?

We will try different connection tomorrow to see if we can find anything.

Thanks,

first take the switch out of the picture hook to the L1 and try to get signal first also leave the motor out for now find a sat with a active transponder make sure the numbers match in your receiver once you find a signal this way then you can install the motor and the switch.

PS............make sure you disconnect power and or coax at receiver, when working on the system. This will protect any damage to LNB or switch.

Yes, we did that and scan the sky for hours. We connected the receiver directly with LNB on the L1 and pointed dish to the direction of Galaxy3C and changed the angle little by little and also changed the direction a little by llittle. No reaction on the receiver.

How to test if the LNB hardware is working?

[rainman]

make sure you have the lnb power turned on with the receiver also make sure you have the Lo freq set to 10750.

There is NO power indicator on the LNB (http://www.sadoun.com/Sat/Products/I...-Quad-lnbf.htm). How I can know it is on? I know my cable is good and the receiver can send command/power to another end because receiver can drive motor with the same cable when motor is connected.

There is NO power indicator on the LNB (QPH-031 Invacom 0.3dB DBS and VSAT LNBs plus VSAT Ku Band Transmitters - BUCs, Receive Satellite TV, Quad CP LP 2-way Satellite communications). How I can know it is on? I know my cable is good and the receiver can send command/power to another end because receiver can drive motor with the same cable when motor is connected.

what receiver are you using? most receivers has a on off option for the lnb.

[FTA001]

DYNAMIC Fortec MPEG2 DVB Receiver

[rainman]

that has the same software as the Mercury when I get home will check which screen tells you if the lnb is on and post it back to you.

is your receiver tuned to an ACTIVE TRANSPONDER while looking for G3C?

if so - can you tell me what is that transponder frequency?

And - you cannot "hold the dish" in your hands.
When you find the signal just pushing on the dish with a finger will cause the signal quality to go away.
The aiming spot is very very small. It is very easy to miss - and make you think that your equipment is faulty when it is really OK.
