SNR-signal, unstable

[maanvol]

I've tried many images on my 'VU+ Duo', but the problem remains: 'SNR-signal' is unstable, no services found. When the 'SNR-signal seemed to be stable, I've pressed the 'OK' on the remote, and the 'SNR-signal' became unstable again! Is there something wrong with the hardware of the receiver?

There's 'a struggle' on the 'AGC-signal' between 76% and 99%. When 'AGC-signal' drops to 76%, the 'SNR-signal' gets to 99%.

I do not understand why the receiver always jumps back to the standard:

Frequency: 11836
Symbol Rate: 27500
FEC: Auto

Only free scan: no

My choice was:

Frequency: 10723
Symbol Rate: 29900
FEC: 3/4

Only free scan: yes

You should put FEC mate for ex..3/4,just give it a go...

Have you tried a manual scan of the whole satellite not just that transponder?

Do your have another sat box that works on your dish setup?

The receiver today took the decision to function again. I noticed that this time 'the lock' was checked! How is this done, and what's its function?

On my Humax everything functions all right.

Now I do understand the problem! The receiver just arrives with an unstable image. I've tried many images -- if not all -- and came to the conclusion that the best image in town is 'BlackHole_VUDUO_136D_USB'. On this image the scanning process works just fine.

In my experience an unstable signal or no signal lock usually related to a dish that is not perfectly aligned. I don't think 'software' will be able to improve poor signals or that image team will release images that 'reduce' the quality of signal.

The fact that the BH image doesn't show you this problem may also be an indication that the scanning process in that image just deals with unstable signals differently. In that context BH may be 'worse' compared to other images.
