Robin Bowes Posted March 20, 2009 Share Posted March 20, 2009 Hi, I'm a fairly long-time DVBViewer user - overall I'm very happy with it. However, I've always struggled with getting it to tune in to all DVB-T (Freeview channels) here in the UK. I've just done a clean XP install on my laptop and installed DVBViewer 4.0 and I'd really like to bottom out the this issue so I can receive all available channels. I have a couple of other set-top boxes running off the same aerial and they all pick up *all* channels. My DVB-T stick can also receive all channels when I use it with Kaffeine under Linux. However, when I do a scan in DVBViewer I don't see all available channels. In particular, I don't see 5 or Film 4. Can anyone help me out? Thanks, R. support.zip Quote Link to comment
Griga Posted March 20, 2009 Share Posted March 20, 2009 http://www.DVBViewer.info/forum/index.php?...st&p=234184 The best way to fix the frequency offset issue is: - Use TransEdit 3.3 (download from the members area). - Try to find information about your local DVB-T frequencies in the web. - Edit your DVB-T transponder list accordingly, or try different frequency offsets, e.g. 706.167 or 705.833 instead of 706 MHz.

CX23882-19 Posted March 20, 2009 Share Posted March 20, 2009 Hi, If you're in the UK, you can use ScanChannelsBDA-UK to find the appropriate frequencies to use: http://www.quantexzone.com/faq/wintv_faq/w...ng_channels.htm Quote Link to comment
Robin Bowes Posted March 20, 2009 Author Share Posted March 20, 2009 Hi, Thanks for the replies. I now have the following transponder list, which seems to be appropriate for my location: [sATTYPE] 1=5000 2=Terrestrial (Tollerton) [DVB] 0=12 1=474000,8 2=498166,8 3=522166,8 4=554000,8 5=578166,8 6=625833,8 7=642000,8 8=649833,8 9=673833,8 10=697833,8 11=705833,8 12=722166,8 How do I get DVBViewer to use these settings? Thanks, R. Quote Link to comment
Robin Bowes Posted March 20, 2009 Author Share Posted March 20, 2009 Aha! Figured it out. The transponder.ini files need to go in: c:\Documents and Settings\All Users\Application Data\CMUV\DVBViewer\Transponders\ I put the above file in that directory and it appeared in the selection list in DVBViewer scan list and I now have all available channels! I really think that this should be sorted out and supported out-of-the-box. Would it be too much to ask to have an ini file with a list of UK Transponder frequencies? R. Quote Link to comment
Lars_MQ Posted March 20, 2009 Share Posted March 20, 2009 Well you got one for us, which does fit all needs? I have no problem including them in the next installer but somebody has to provide them. Quote Link to comment

I have no problem including them in the next installer but somebody has to provide them. Ha! How did I know you'd say that! The thing is, that particular file is only good for the two transmitters that I am nearest - Bilsdale and Emley Moor. I'm sure it would be possible to put together a list of all frequencies for all UK transmitters, but I'm not sure I'm the best person to do it. I can give it a go. Personally, I think DVBViewer should scan the centre frequencies *and* +/- 166Khz either side (or whatever the value is). Most of the other software I've used does this. R. Quote Link to comment
Griga Posted March 21, 2009 Share Posted March 21, 2009 Does DVB-T in the UK use frequencies in the VHF range (below 474 MHz)? Without them it would be easier to provide a solution. Quote Link to comment

I don't believe so but, as I inferred earlier, I'm not the best person to give a definitive answer. The lowest channel seems to be on 474Mhz (see here). I dare say you won't go far wrong if you use centre freqencies (Fc) from 474Mhz to 850Mhz 8Mhz steps and scan Fc-166Khz, Fc, and Fc+166Khz. R. Quote Link to comment
Griga Posted March 21, 2009 Share Posted March 21, 2009 Ok, here is a general solution for scanning DVB-T UK. Designed for the blind scan capabilities of TransEdit. Please note: In its initial state the attached transponder list is not usable for scanning with DVBViewer. 1) Download TransEdit 3.3 from the members area. Please follow the installation instructions. 2) Launch TransEdit. Select Info -> Configuration Folder (opens an Explorer Window). Close TransEdit. Store the attached file Terrestrial_UK.ini in the Transponders subfolder of the Configuration Folder. 3) Re-launch TransEdit. Select "Terrestrial (UK)" on the left side of the main window. Initially this transponder list is empty, but it contains presets for the TransEdit Blind Scanner. 4) Click "Blind Scan" and, without changing anything in the Blind Scan Window, "Scan". The TransEdit Blind Scanner will now scan the centre freqencies from 474 Mhz to 858 Mhz with 8Mhz steps, after that the same frequency range with a +167 KHz offset, then with a -167 khz offset. Altogether 147 frequencies. It will take some time. 5) After the blind scan is finished, the Terrestrial (UK) transponder list will contain all frequencies resp. transponders of your region that deliver a signal. Save the transponder list by clicking "Save" on the left side of the TransEdit Main Window. It can be used now in DVBViewer. 6) Select the scan results in the TransEdit Scanner Window (-> Select All) and export them to the DVBViewer channellist by clicking "Add/Update". Done!

uglyned Posted May 25, 2009 Share Posted May 25, 2009 Thanks Griga. This is really helpful. Quote Link to comment
Mr Jolly Posted October 19, 2009 Share Posted October 19, 2009 (edited) Griga, that is really helpful. This is how I did mine. Coming from Nebula I knew nothing about offsets. First point was Ofcom to get my channel numbers for the UK DVBT muxes. http://www.ofcom.org.uk/static/reception_a.../index.asp.html I then used the following formula to convert from UHF channel number to MHz. Frequency = 8n+306 where n=UHF channel. For Oxford I get the following: 29 - 538MHz 34 - 578MHz 48 - 690MHz 51 - 714MHz 52 - 722MHz 68 - 850MHz The offset is listed as 0, - or +. Add or subtract 166.67kHz (0.16667MHz) 29 - 538000kHz 34 - 578000kHz 48 - 690000kHz 51 - 713833kHz 52 - 721833kHz 68 - 850000kHz Edited Europe.ini in Application Data and pointed DVBViewer at that file when tuning. Worked a charm. Edited October 19, 2009 by Mr Jolly Quote Link to comment
remlap Posted March 1, 2010 Share Posted March 1, 2010 My local analogue terrestrial relay switches of BBC Two on Channel 46 on Wednesday and full switch off is due at the end of the month. It will be using these three UK UHF frequencies C43 C46 C50 Is there anyone able to help me create an ini just for these three save me doing a long blind scan? Cheers Quote Link to comment
Cian Posted March 5, 2010 Share Posted March 5, 2010 It might be as quick to do "Scan Frequency" instead of "Scan Range" since you know the three channels involved. Just use the up/down buttons to select the channels. Quote Link to comment
