Probleem met kanaal zoeken

[edsel]

Hallo,

Ik heb een paar dagen geleden mijn VU+ Solo2 met "Openvix 6 3 007 Release Vusolo2 Usb" geflashed. Alles werkt uitstekend, maar wanneer ik kanalen ga scannen (1 LNB, gericht op Hotbird 13B/13C/13E) dan vindt mijn Solo2 slecht 23 kanaler. Na wat zoeken kwam ik tot de conclusie dat hij maar één transponder afzoekt. Als ik een blind scan doe dan vindt hij 4 transponders, maar de gevonden kanalen horen allemaal tot dezelfde transponder (zie beelden).

Ik heb van alles uitgeprobeerd, maar welke instellingen ik ook verander, ik krijg steeds hetzelfde resultaat.

Is hier iemand die licht kan werpen op dit probleem?

Bij voorbaat dank,

When I do a manual scan I select Type of Scan Single satellite and define the satellite.
Question 1: Have you attached the LNB coax cable to Tuner B?

Can you try with my settings if you get more

[edsel]

Hallo Nekrub2,

Bedankt voor je antwoord.
Ik heb zowel LNB A als LNB B geprobeerd.
Ook jouw instellingen heb ik geprobeerd, single satellite, enz. Maar ze geven allemaal hetzelfde resultaat.

[nekrub2]

Can you check the signal quality SNR on one of the found stations.
Setup > Tunters & Scanning > Signal Finder.

If the SNR is low (50% or below) I would try adjusting the dish. I get for my stations 85 - 95% . After adjusting your dish you can do a second scan.

Good luck

[nekrub2]

What stations can your receive? I noticed that they are all HD and having checked them on Lyngsat Hotbird I did not find these frequencies. Could it be that you direct to another sat nearby?

[edsel]

Hi,

The SNR is around 80%, but only for one (1) responder. All the other frequences are zero.

65306

[edsel]

These are the stations on the website of lyngsat:

65307

[nekrub2]

From your setup picture I see that you have setup Tuner A. You confirmed that you have plugged in you coax cable to Tuner B.
You should set up Tuner A to loop-through and Tuner B to
Configuration Mode Simple
Mode Single
Satellite "automatic"

I cannot give you a screenshot as I have a twin head and a diseq to switch between astra 19.0 and hotbird 13.0. I just refer to the openvix manual.
Hope this helps.

[edsel]

Thank you for your support, nekrub2!


I made the settings you asked for, but Satellite "automatic" did not work for me: It scanned a few satellites and returned with Satellite: "not configured"
Then I chose Satellite: "Hotbird" instead and did the automatic channelscan and it returned only the 23 same channels.

Before I opened my thread here on the forum I had moved the Coax cable to Tuner B since nothing worked. It was a last try to see if the problem depended on the A Tuner. But it shows the same problem and only finds these 23 channels.
So Now I have put the system back as it initially was:
Coax cable on Tuner A
Tuner A on Mode: simple, Mode Single and Satellite: Hotbird
Tuner B on "Equal to tuner A" (I guess this is the same as "loop-through" since that choice did not exist)

With these settings I made a "Blind Scan" and it returned with the 23 channels again.

There is a similar thread in the VU+ Solo2 forum

https://www.world-of-satellite.com/showthread.php?65992-Satellite-config

The moderator Abu Baniaz suggested as I did. Maybe you contact him via PM and send him a link of this thread. I wouldn't know what else I could suggest you.

[edsel]

Thank you, nekrub2!
I think I will start a new thread in that subforum.
But it can also be something wrong with my equipment.

Can you translate the first few posts please?

Channel search problem

Hello,

A few days ago I flashed my VU+ Solo2 with "Openvix 6 3 007 Release Vusolo2 Usb". Everything works great, but when I start scanning channels (1 LNB, aimed at Hotbird 13B/13C/13E) my Solo2 only finds 23 channels. After some searching I came to the conclusion that it only scans one transponder. When I do a blind scan, it finds 4 transponders, but the channels found all belong to the same transponder (see images).

I've tried everything, but no matter what settings I change, I always get the same result.

Is there anyone here who can shed light on this problem?

Thank you in advance,

Edsel

Hello Nekrub2,

Thanks for your reply.
I have tried both LNB A and LNB B.
I also tried your settings, single satellite, etc. But they all give the same result.

[Joe_90]

Now - Hotbird at 13E should return 1000's (well at least 1,000:)) channels if you are scanning the entire satellite constellation, so getting only 23 channels would indicate that only one transponder is being scanned. @edsel - are you sure that you are scanning the entire satellite and not just one transponder?

[abu baniaz]

"Equal to" means you have exactly the same hardware hooked up to the tuner. For Solo2, to use internal loop through, the signal wire must be hooked up to Tuner B.

You have not fully described the hardware connected to the tuner. Is it a single universal LNB? Do you have any diseqc switches or splitters? Are you using any face plates? I presume that you have checked F-plugs are fine. And lastly, sometimes, the PSU fails and it cannot supply the required current for the tuner. Are you able to test another 12v PSU?

[edsel]

@Joe_90 - Yes (I think so), it is scanning all the transponders but finds only channels att one (1) transponder.

@abu baniaz - Here follows the hardware:
VU+ Solo2
A single universal LNB
No Diseq switches
I don't know what Face Plates are
F-plugs look ok and I get these 23 channels clear.
Failing PSU sounds as a possibility. I don't have another 12V PSU, but I can measure the PSU output while it is scanning. If it has issues the voltage should drop below 12V.

For Solo2, to use internal loop through, the signal wire must be hooked up to Tuner B
I did not know that. Then I will move the coax back to Tuner B and change the tuner settings.


Thanks for your help! I will test the PSU this evening.

[Joe_90]

@edsel - I scanned 13E last night just for free-to-air channels and got almost 1,000. Once you eliminate a configuration (or cabling issue) as per @abu's posts, I think you need to verify that your dish is pointing correctly at 13E. My location is in Ireland at 6W, so it may be that you can't receive all beams in Sweden, perhaps?


EDIT - I checked the beam coverage for 13E in Lyngsat and Sweden is well within the pattern, so you should be receiving almost the same signal as me.

[abu baniaz]

While you are testing, disable the tuner with no signal wire. It does not matter whether you use A or B (unless you are using internal loop through). Can you please post a screenshot of the scanner options you are using, so that we can double check. Can you also confirm whether you are using a different satellites.xml file or using the one that comes with the image? Some channel lists replace the xml file. The one in /etc/enigma2 is a user one and takes precedence, the one in /etc/tuxbox is the system one. You can easily replace the xml file using "xml update", it is pre-installed on Vix

For your PSU, you will have to check the current. I think that is where the PSUs fail rather than the voltage dropping. Any 12V PSU with at least 2.5A should do for testing.


An example satellite face plate is here:


https://www.screwfix.com/p/british-general-900-series-1-gang-f-type-satellite-socket-white-with-colour-matched-inserts/97776


You should keep your tuner set as simple, single, 13e.

If it helps, one way of getting clear/good screenshots id described in following thread:
https://www.world-of-satellite.com/showthread.php?44054-How-to-take-screen-shots-How-to-attach-files


And are you able to see the LNB easily and safely? Are you sure it is not damaged? A friend was not getting any services recently. We found his LNB in the pictured state. I am pretty sure it is a hardware fault: signal wire, dish, lnb or PSU.

[edsel]

@abu baniaz
I looked for the satellites.xml file and this file exists only in /etc/tuxbox (507377 Apr 27 19:10 satellites.xml), not in /etc/enigma2.

The LNB was installed by a technician for about 10 days ago and he received Hotbird channels on his little screen, sitting on the roof. I also receive 23 Hotbird channels with 80% SNR.
I believe - like you - that there can be some hardware error.

I don't use a face plate, the cable comes directly from the LNB.

@Joe_90
Hotbird is popular in Sweden and has a strong signal. I have received it before with other equipment.

Thank you for your help, guys. Much appreciated.

[bellejt]

did the guy/technician not tested with your decoder ?

[abu baniaz]

Last software check:
When you change tuner configuration, some entries remain. To exclude any "Advanced" settings you had previously used, try one of the following:

1. Flash the image again, do not restore settings after it restarts. Ensure you set tuner with the signal wire as simple, single, 13e
2. Stop enigma2 with "init 4" command. Edit the file called "settings" in /etc/enigma2/ by deleting all the lines that have "nim" in them. Transfer back, restart with "init 3". Ensure you set tuner with the signal wire as simple, single, 13e

[edsel]

@abu baniaz
Here follows the screenshot of the scan settings:

65321

I disconnected the internal harddisc, just in case it took too much power, and measured the current and voltage during a scan.
The voltage was stable around 12.2 V and the current around 1.15 A. During boot was the current around 700 mA.

I saw your last message only now and I will make the software check you propose. I come back with that tomorrow.

Thanks again.

65322

[Joe_90]

@edsel - you are only scanning one transponder! (predefined transponder). Click the "Type of scan" settings (use right arrow) until it reads single satellite and then scan.

[abu baniaz]

@joe_90
He had tried autodiseqc earlier and it did not find 13e. Can you please double check that these are still correct? We are checking transponder for Rai1

@joe_90
I have now scanned with type of scan: Single Satellite
it gives the same result, the same 23 channels.
It is strange that every time I go back to Manual Scan, the type is changed again to Predefined Transponder.

@abu baniaz
I have stopped Enigma2, deleted all the lines with "Nims" in /etc/enigma2/ , restarted and made a scan but it did not change anything.

I guess the next thing to do is to exchange the LNB.

Can't actually check right now, but I used default Vix settings and got all the RAI HD channels (except for the encrypted ones of course). Over 900 channels tuned in.

[edsel]

Today I have been looking on the roof and this is the LNB that is installed, för less than 2 weeks ago.
Just wondering if you know this brand.

65335

[abu baniaz]

That is not a universal LNB, it is a unicable LNB. The brand is not really important it is the frequency/scr channels that it uses.

Pdf:


https://www.mtigroup.com/upload/media/products/03_Satellite-TV-Solution/MTI_dCSS_24UB_LNB_AKU0_U05_M103_Spec.pdf

Have a look at the existing unicable file and pick one that has matching bands.


https://github.com/OpenViX/enigma2/blob/Developer/data/unicable.xml



One guide to setting unicable LNB:
https://www.world-of-satellite.com/showthread.php?60640-GT-Sat-GT-dLNB1DY-and-tuner-configuration

[abu baniaz]

Use same settings as:
Inverto
IDLU-24UL40-UNMOO-OPP

It has following bands that match your LNB
<product name="IDLU-24UL40-UNMOO-OPP" positions="4" format="jess" bootuptime="800" scrs="1210,1420,1680,2040,1005,1050,1095,1140,1260,1305, 1350,1475,1520,1565,1610,1725,1770,1815,1860,1905, 1950,1995,2085,2130"/>

We will add the device to the unicable file later, but that is not too important. Receiver just needs to know what frequency to communicate with LNB.

Edit: Please hook up wire to Tuner B and configure that tuner only.
Leave tuner A as not configured for now. I have a test for you to do after we have you working fine.

[edsel]

Ok, thank you. But what is a better solution? I have some of these LNB's (see picture).
What do you advise me? To continue with the Unicable LNB and make the changes you have suggested or put the old 'Black' LNB?

65336

BTW Sorry that I thought it was a Universal LNB that was mounted.

[abu baniaz]

No need to be sorry. Golden rule of tuner configuration is that it must match hardware. Finding out the LNB type is important. Well done and thankyou for getting a pciture.

Why did you remove the old LNB?
What other LNBs do you have installed?
What is the complete setup?

From what I can see, the old one is the narrow one that allows closer fitting. It is universal. As you have fitted the wider/standard one, that is not an issue.

If you are going to add 13e to a diseqc switch, you will need a universal one. There is a thread on another forum about using diseqc switches with unicable LNBs, I obviously can't post a link to other forums otherwise I will get an infraction. If you are not going to use a diseqc switch I would keep the unicable one. The test I was going to suggest will/should allow you to configure both tuners for 13e. But let's not confuse things, one step at a time

[edsel]

Thank you for your explanation. Then I will continue with this LNB until I need a diseqc swith.
I have not yet changed the changes in the unicable file but just made a scan with Unicable - Inverto and it has already given 730 free channels!
After changing the unicable file it will give all the channels.

You asked about the other LNB's, for some years ago I had an other receiver and used these LNB's for different satellites. The equipment was old and had problems and I bought a new receiver, the Solo2, but it has stayed in the package for several years. Until for some weeks ago when I got help with adjusting the parabole and a new LNB. The fact that my neighbours (in south direction) have cut som really high trees has helped me in that decision.

Thank you very much both, @abu baniaz and @Joe_90! I have learned a lot and the results are that the satellite receiver now works.
Great with such a help!

You will meet me more on this forum.

[abu baniaz]

Compare with your neighbours/friends nearby and see how many services they get. They must scan using same parameters as you. If there is a massive difference, you may need to tweak the dish.

Changing the xml file won't make a real difference. The only possible difference is the boot up time. Basically, the receiver sends a request before the LNB wakes up. You can modify that (by improving boot time), restart and scan again. The file should be in /etc/tuxbox. Or install satellite equipment control plugin which will allow you to alter the delay.

Can you now configure tuner A. The options/settings will be similar to what you have set for B.
However, Tuner A does not have its own signal wire, you are going through another tuner. So set connected to yes. You are going through tuner A, so that is the one it is connected to. If it does not show these, then no problem. You should then be able to use both tuners independently. This is why I always stress Unicable technology and FBC technologies are independent.

[edsel]

I connect the cable to tuner B, but do I not set 'internal loop through' for tuner A?

[abu baniaz]

I did not say to use loop-through after we established it is a unicable LNB. I said: "The options/settings will be similar to what you have set for B." Just to clarify, set tuner A (which has no signal wire) as:
Advanced, unicable LNB, connected = yes, connected to Tuner B

[edsel]

Use same settings as:
Inverto
IDLU-24UL40-UNMOO-OPP

It has following bands that match your LNB
<product name="IDLU-24UL40-UNMOO-OPP" positions="4" format="jess" bootuptime="800" scrs="1210,1420,1680,2040,1005,1050,1095,1140,1260,1305, 1350,1475,1520,1565,1610,1725,1770,1815,1860,1905, 1950,1995,2085,2130"/>

@abu baniaz
I can't find this file.
In /etc/tuxbox I have only the files
atsc.xml
cables.xml
satellites.xml
terrestrial.xml
timezone.xml

In none of these files I can find "Inverto".
What should the filename be?

[abu baniaz]

My apologies, the unicable.xml file is in
/usr/share/enigma2

There are two sections, one for switches and one for LNBs.

No problem. Thank you!

[abu baniaz]

On second thoughts , it is a better match to the Megasat diablo because it is not progammable and also has the longer boot time. So easiest option is to just do that.

I have added the LNB here:
