[SF8008] channel searching problem

[Huevos]

Here are two screenshots of what is happening with RTL Living on 11512H on 16E

This is the service info when scanned correctly:

Attachment 61995

Here it is when scanned incorrectly:

Attachment 61996

Provider and ONID are different

And based on that I would assume the SI tables are broken on that transponder.

Would be handy if someone could grab a transport stream recording.

Also service type changes.

<transponder frequency="11512000" symbol_rate="30000000" polarization="0" fec_inner="3" system="1" modulation="2" />
<transponder frequency="11512000" symbol_rate="30000000" polarization="0" fec_inner="6" system="1" modulation="1" />

So 2 transponders with very similar details. Second one is from South Africa beam. Try removing the second from satellites.xml and then reboot and try the scan again. Just to make sure there isn't some strange interaction.

I had tried that and it seemed to improve things. 11595H is another troublesome one on that bird and harder to scan successfully.

May not be anything to do with the poster's problem but t is worth mentioning that yesterday would not be a good day to scan Satellites. From the Guardian - In May 1921, a giant sunspot erupted, ejecting masses of solar material towards the Earth. This solar storm produced auroras visible all the way to the equator, and a rash of fires.

A telegraph exchange in Sweden was the first to burst into flames, followed by a control tower near New York’s Grand Central Station. Long stretches of telegraph wire were acting as aerials; the resulting induced currents were strong enough to blow fuses and cause overheating, sometimes resulting in fires.

May 1921? Yes that was a bad one but hardly relevant now is it. There are solar storms quite often and there's been a lot recently but they don't affect the satellite frequencies to any great extent. Actually RF conditions were fairly good yesterday with plenty of signals on the higher HF bands.

I've got my tinfoil hat ready in case of CME -

hi, so are we agreeing we need to edit the sat.xml file, anyone done this and confirm problem is gone 100% after editing the file, or are there still problems

thanks

[Huevos]

@clive01, you need to do your own testing. Every STB and setup is going to be different.

Remove this transponder and this transponder from satellites.xml and try again.

hi this is a part of my altered sat xml file

<transponder frequency="11595000" symbol_rate="30000000" polarization="0" fec_inner="3" system="1" modulation="2" />
<transponder frequency="11595000" symbol_rate="30000000" polarization="1" fec_inner="4" system="1" modulation="2" />

i scanned this freg, as a test, first time all names etc, then rescanned again, didnt even come out of the tuning menu and this time, correct names etc, so pretty sure it is not the xml at fault here.

I tried a few fregs on 16 east,like this no different sadly, when using the altered sat.xml file

[ronand]

How many transponders on 16e are you having a problem with? List them please

[clive01]

hi, yes i will do this today, but just to be clear its not just 16 east, 39 east, and 30 west i think also have this issue, maybe more, ill list the ones on 16 east today at some point

thanks for your reply

[ronand]

Just stick to 16e for the moment. 11512 and 11595 are the only ones I could find any problem scanning. The signal levels are lower on those transponders.

[clive01]

hi yes 11595 and 11512 , if i do a full satellite 16 east scan i get no channel names on these 2 freg, if i go to that freg only scan, i get the channel names, signal is fine, and depending on the type of scan, seems to be the "issue" the dish hasnt moved, getting 94% quailty on th2 11595 freg, other fregs are weaker with no problems

the 11512 freg when i scan it and get the freg in the channel name, i get tune failed, then i scan again, and it in most cases works then, but something i notice, on 11512, there is a channel named 11512h sid 0x46 so my stb is on that channel, i then go into the tuning menu and the stb should be showing that freg, but it isnt, it, instead it is showing 11262 h, in the transponder section.

If i go to say 11636 tv slo, and then go into the tuning menu manual scan, the stb displays that freg 11636, this dont happen on the problem 2 fregs, so it might be a clue, please try it yourself, and see if the same is happening, i hope i explained it so its clear, what im trying to say.

thanks

I don't have any of those problems - you must have messed something on your system. When I do a full scan on 16e I get the channels on 11512H about 70% of the time but the channels on 11595H only about 20% of the time. It seems like a problem with the signal (the data may be corrupt).

hi, the dish is 1.2 metre, no ber, 94% in quailty, other sats also effected, ill be amazed if it is anything to do with signal, the LNB was replaced not long ago also.

The dish was lined up, by a guy i know, who use to do satellite motorized installs almost daily, i never get any picture blocking etc, its just the channel names effected.

If others are getting this issue, please comment, i might see if i can hook up a different stb, but i think that is open pli image, so may not be much use.

It has an old image on it, from years ago.

thanks to all who posted
