Problem setting up tuner at SCR(Unicable/JESS)

[Mick12334]

Have you tried using the basic satellite setup?
Go into the Menu, Setup, Tuner and Scanning, and set the configuration mode, to simple, single LNB, for 0.8W, and then check if you can scan in any channels.

The reason I wanted you to test your Duo 4K, on one of the other LNB's, currently connected to your Duo 2, was to confirm that the problem wasn't with your receiver, as you can alter your LNB settings, on your receiver.

The basic reasons, for loss of signal, are:
1. Cable problems, either a break, in the cable, or the F Plugs not done correctly. I had a problem, when I set up my system, as the F Plug was too tight, for the cable, and cut off nearly all the braid, causing an intermittent problem.
2. The dish has moved, and no loger aligned.
3. The LNB has failed.
4. The receiver has a fault
5. The Tuner configuration is wrong.

Thanks for the detailed description.
Single LNB, for 0.8W works.
I am about to buy a new cable that is adapted for SCR(Unicable/JESS).

 

[Akita]

Have now installed with new cable.
The picture came right away.
Thanks for the help.

 

[Akita]

Now it has happened again with the new cable that I got to work with.
No signal from the satellite.
Black box.
Can a microwave head work sometimes and then stop working and work again then stop working etc.

Any LNB can be faulty, but first you need to check everything else, especially your connections.
What signal quality do you have?
Have you altered the skew, rotation, of the LNB?
Is the dish correctly aligned?
You might have to check your receiver, in case something is failing, as you have another dish setup you can test your receiver on that dish/LNB setup.

Signal quality when it worked 75% SCR?
Have you changed the LNB tilt, rotation? No.
Is the dish correctly adjusted? Yes
Works perfectly with LNB setup.

When I connected the microwave head for the 1st time, SCR worked for a while.
Thought it was due to a bad cable.
Bought a new antenna cable class A.
Worked for a while now no signal again.

 

[Akita]

Tried again today.
Now it works.
Can a microwave head work this way.
Works for a while and then no picture, turned off until the next day and works again.

Is your receiver well ventilated? An overheating problem, can cause this, in either the LNB or receiver.
You might want to do a google search, for your LNB, to see if this is a known problem.
You can also contact your supplier, and explain the problem to them.

Thanks for the tip.
Heat might be an explanation.
Now it's on top of another receiver that heats.
I'm moving so maybe the problem will be solved.

 

[Mick12334]

Just put some spacers, between the two receivers, at each corner, sufficient to allow good air flow.

 

[Akita]

Have placed the box separately.
Same problem.
Can the receiver work poorly with different SCR microwave heads.
What I have works sometimes and then loses the signal completely.
LNB works with good signal strength.

 

[Akita]

Now I'm tired of all the errors with the connection with the microwave head GT-SAT model GT-S3DCSS24.
Works one day and the next day there is no signal.
Must be something wrong with the microwave head.
Could this microwave head be a good alternative?
Dur-line uk 124-3l dcss

 

[Akita]

I have now acquired a new microwave head.
DUR-Line UK 124-3L and it worked straight away.
How strong is the SNR usually?
I get between 70%-75%.
Maybe I need to change to a different satellite dish?
Is quite old 90 cm but otherwise no damage that I can see.
Recommendation for a good satellite dish for central Sweden.

After fine-tuning the microwave head and dish direction, I got the SNR up to about 81% in cloudy weather.
