View Full Version : which Transmitter
Hy Guys
I have Vu+ Duo2 with Opollo 12
Tuner A DBS-S Nim(AVL622) (dvb-s2)
Tuner B DBS-S Nim(AVL622) (dvb-s2)
Tuner C DVB-T Nim(CXD1978( (DVB-T)
1 Terabyte harddrive
bought from our sponsor WOS
Satellite part is fine
The problem is with the terrestrial TV side.
in tuner configuration you select the transmitter you want (quite a large selection) but my local transmitter is Sutton Coalfield (this is where my ariel is pointed) but is not listed.
The only one out of the list i can get programs from is Sandy Hill which is at the back of my ariel when looking on the transmitter map.
The signal is 80% SNR but only 10 % - 20% AGC which is not good.
Is there anything I can do to up date the card with Sutton coalfield on it?
Does this card get the free HD programs as I get none from manual scan on Vu+ Dou2 box ( but do on the built in free view on the tv in the bedroom, same ariel and good AGC as well ?
Do I need to buy a better Turner card from WOS to get the sutton coalfield transmitter and the free view HD channels
many thanks

you could have a read of this thread for help with DVB-T scanning.

Have you tried using ABM to scan your local transmitter ?.
Hi Phoenix
I read all the relevant posts i could find on the subject but no help
No I have not tried scanning with ABM, I manual scanned all uk transmitters.
as I said the local transmitter for this area is Sutton Coalfield but this does not come up as an option.
Thanks anyway
Try ABM see if you have better results with that.
@johnnym - the main Sutton Coldfield BBC transmitter multiplex is on C43 which is 650MHz (650000000), so you could try a manual scan on that. It is a powerful transmitter - 200Kw, so will have good range. This will give you all the BBCs, so will establish that you have a working tuner. Your DVB-T tuner is only good for SD - not HD channels. You would need a DVB-T2 tuner for those.
The problem with the terrrestrial scan file which is included with the ViX release is that it does not include the Sutton Coldfield transmitter group specifically. You could always set your tuner to the DVB-T Europe setting which will allow you to do an automatic scan, which takes a bit longer, but will scan all channel frequencies and you may end up with duplicates.
The AutoBouquetMaker (ABM) plugin does have Sutton Coldfield as an option, but from what I can determine from looking at ukfree.tv, it seems to be set on C40+ (626MHz) which is the BBC HD multiplex, which is no good for you. I thought it should be referencing the BBCA multiplex on C43 (650MHz) which is what you need for SD. Nevertheless you could try it and see if it works.
Hi Tony
Thanks for the reply.
Yes the AutoBouquet maker does have Sutton coalfield but times out as does all the other i have tried around my area.
I did already do a manual Europe scan and it does find some channels but the signal is so poor the picture drops off even on the stronger signals.
Is there a DVB-T2 card available for the VU+ Duo2 and will it have sutton coalfield on it.
The card does work on the Sandy heath transmitter which is at the back of the ariel so if i turned it around the signal would be good but it is the top of the range hy-gain i had installed a few months ago and don't want to move it as we also us it for the free view on the TV in our bedroom.

Can you try to scan with the following settings please?

Ok - forget ABM for the moment. Abu's post above may not help as you seem to not have a DVB-T2 tuner. There are issues with the way ABM is set for your DVB-T tuner. With your tuner set to DVB-T Europe, do a manual scan on channel 43, which is the Sutton Coldfield BBC multiplex. If your aerial is pointed at Sutton Coldfield this will bring in the BBCs. The problem with the automatic scan is that it may pick up the Sandy Heath or other transmitters first, before it picks up the stronger Sutton Coldfield transmitter. If the channel 43 scan works I will give you all the other manual data for Sutton Coldfield.
Here's a screenshot:
Hi Abu
I have tried that setting and do get the 121 channels but they are un-watchable as the picture flicks of and on don't know what transmitter that is locking on too.

Have you tried to scan as per fat-tony's advice?
Might be an idea to enable clear before scan
Hi Tony
I tried your setting and got the BBC channels but when i looked at the signal strength 80% / 90% and AGC of only 10% it looks like its on the sandy hill transmitter the back of my ariel.
As you said the card is not the best I think WOS has a T2 one for about £59 so I will get that and hope for better result.
if i have to i will get the ariel turned round to the sandy hill transmitter but the funny thing is its perfect on the built in free view in the tv HD programs and all and all the aerials around here goto the sutton coal field transmitter.
thanks for your time

Hi Abu

I had a similar issue with my local transmitter being on higher frequency than a more distant one. When I did a complete scan the more distant transmitter was being found first and the channels were stored and my local transmitter was being skipped. As a result I had lousy reception. The solution is to do a manual scan on the specific frequencies used by your local (Sutton Coldfield) transmitter as per my post above. You scan on a specific transponder - in your case UHF channel 43 (or you can type in a frequency - 650000000 if you prefer more typing!). If you confirm that works, then try chan 46, chan 42, ch 45, ch 39 and finally ch 51. As abu suggests, set "Clear Before Scan" to yes on the first scan (ch 43) and make sure it is off for subsequent scans.

What's wrong with signal strength 80% ? Is the picture ok? If your aerial is pointing at Sutton Coldfield (which is a friggin powerful transmitter) and your reception is stable on those specific channels I gave you, then what's the problem? My tuner gives a signal strength of 44% and the picture is rock solid. The information from these tuners is only relative. If you have signal strength of 80% - 90% it's absolutely fine. Signal quality is what counts, not signal strength.
What's Sandy Hill? Do you mean Sandy Heath? The BBC channels from Sandy Heath are on ch 27 - so no way is a scan on ch 43 coming from Sandy Heath. You do need to do a clear on your next scan to eliminate any duplicate instances of channels. Just start of 43 with a clear then follow with the others I gave. No HD possible without a DVB-T2 tuner, though.

Hopefully someone who knows will post an amended terrestrial.xml file with sutton coldfield details added. It goes in /etc/tuxbox. We can then add this to the feeds for all OE-A images.
http://www.ukfree.tv/txdetail.php?a=SK113003
It seems you and @micsave are in the same region. Your having an internal tuner may fare better. The ABM thread went cold with your region, it would be good if this can be revived and resolved. Perhaps once you have a picture that is watchable, you can take some logs as per the other thread.
abu baniaz
02-07-14, 03:40
Here is an xml file for you to test.
1. Backup you existing one from /etc/tuxbox/
2. Replace with attached
3. I will suggests you start with no channel details on your receiver (details below). Backup existing bouquets etc using Dreamboxedit etc.
4. To remove all cahnenl data, telnet the following command
init 4 && rm -rf /etc/enigma2/lamedb && rm -rf /etc/enigma2/*.tv && rm -rf /etc/enigma2/*.radio && init 3
5. When you receiver restarts, set your tuner for Sutton Coldfield
6. Ignore the sat channels for now. Perform a manual scan using the DVB_T tuner, having toggled the settings to match attached picture.
I'll keep this brief as I'm typing this on my phone. If I do a manual scan with it set to Europe DVB-T it does pick up all available channels from Sutton Coldfield with no duplicates. ABM still fails though
abu - what's constellation = "4" and transmission mode = "3" mean in your xml file? Both those values seem to be outside the range documented in the header. Are they new? Is there an explanation for them published anywhere?

I am afraid I do not know, I copied my area and replaced the frequencies with those for sutton coldfield. Might as well as try until someone who knows better posts.

That could be risky as HD tuning parameters are different in some regards to SD tuning. Problem there would be that the tuner may fail to lock on to the signal. Do you know who is the keeper of these details? Andy or Peterj perhaps?
I always use the default auto parameters and they seem to work, but if you explicitly set invalid parameters I don't know what would happen - tuning fail perhaps?

Then please upload the correct one and amend the other risky one where applicable. Using the details as thy are, scanning took less than 1 minute for me and all the channenls worked.
I was only trying to help. If it worked, well and good. If it didn't then the OP can revert to his saved one. There shall be no more involvement from me in this thread. Sorry for trying to help.
Conflict of proverbs.
"Too little knowledge is dangerous" vs "Better to try and fail than fail to try". Looks like the first one should rank higher considering my error stopped release of build 006.

abu - I understand you're trying to help the OP (as am I), and I'm happy to edit the terrestrial.xml file for testing (I can only test for Saorview, though), but I would rather start editing from an informed position where I knew which parameter values were valid for DVB-T2 and which for DVB-T. I found that if I used the "auto" values they work fine in my Quad Plus terrestrial tuners, but other hardware may be more picky about parameters. I'm probably too analytical about these things, so my bad! I'll pm Andy and see if I can get the additional parameter values.
Hi Abu
yes and did clear before scan.
I think the standard terrestrial / cable tuner is not up to the job and want the HD side so will up-grade to T2 and try again.
many thanks for your and Tonys help
