SES and ITV testing new FEC settings

[Archive-8]

Please take the location chat to pm - we are getting well off what was an interesting topic

I quite agree. It's not open to public discussion. Thank you @Analoguesat

What is going on, is my LNB going faulty, or is SES experimenting something? As 11052 now gets massive interference with some new data channel near?

That would probably be 11008V from astra 2C, has been causing problems with BBC Scotland HD for some time, skew adjustment should rectify the problem.

No, it cannot be that interference. Skew has been checked to get optimum from 10994/11023 that the 11008 was affecting. Now whole new slopes are appearing in the spectrum, when never before seen in Horizontal side.

 

[Analoguesat]

Anything new been lit up on Badr 5 at 26E?

 

[popolon]

here is now older spectrum from 12.02.2015. And latest from today. When you compare these, it can be seen that some signal slopes has been appeared after 11052H

I have an Invacom QDF-031 quad on a 1.8m looking at 19E which has started doing all sorts of weird things with transponders disappearing and re-appering on the wrong frequencies. I haven't bothered to swap the LNB yet, will wait for better weather, but I think it must be faulty. Could something similar be happing to you?

Tried to check , using the GI box in the bedroom as wife has main system in use at the moment, couldn´t see anything on 11122 H, or anything near it. But it is a very basic box, will try later when the boss has gone to bed!

same as Popolon saw, is here too (here 125x140 antenna +BU lnb)

That is weird. I'm in the UK at the moment but I don't have a spectrum analyser of any kind. My receiver is still picking up the transponders as normal and I haven't found any new ones.

Anyone else able to check this side of Europe if there are any obvious changes?

Are there any Lyngsat type websites that list data transponders?

Just checked with the S1 spectrum ( not the best machine in the world! ) but gives me some idea.
No sign of any peak signal on H frequency, but can see high level on V, 11008. Dont trust the spectrum on the S1 too much, but would expect to see something of a bump on the display if there was something there

 

[Archive4]

Checked flysat, nothing new there, as of yet. S1 cannot see anything unusual of H txp´s

H your machine is much better than mine, can you see anything?

Popolon, are there any other sats you have had " bleedover " from in the past?

He's got a 5m dish, I'd be surprised if there was any inference from nearby satellites with something so big.

I have had frequencies appearing after 11126V, something like 11141+11151V, as seen from spectrum view. I have not figured out from were those come.

That triggers a memory - I seem to recall someone having similar problems when tuners were overloaded when high levels of signal 2F (I think) went into service and they ended up with all sorts of spurious signals.

Is it possible you are getting similar effects from the 2C data channels overloading your tuner?

What if I have adjusted lnb to not center of 5m dish? E.g. 3mm wrong? Then something would be coming from other satellites? Or that because this dish is designed optimally to be used with cassegrein subreflector, now some unwanted signals can occur from outer edges of dish?

Wouldn´t normally disagree, but, we both know the affect 11008V is having on us, even though it is from 2C. I know this is not far from 2 E & F, but it still has an effect on our reception. I´m also aware that some BADR signals can cause problems with reception from 28.2.
Conversely, I have personally experienced picking up signals from 28.2 when locked onto BADR to pick up the MBC film channels on a 80cm dish, got CNN and Sky news, even though the Saudi package on 12015 should have wiped it out!

Is this the correct point to say

" take one attenuator every hour " and hope for the best!

But why today those H side signals appeared? Data channels have been there already before.
