Tom, the commercial multiplex operators didn't want to pay for fitting digital transmitting equipment to the 994 relay transmitters. They figure that the 80 transmitters that already ran Freeview before switchover will cover something like 90% of the population once the power is turned up after switchover, and they don't care about the other 10%.

TV advertising revenue is now way down and this decision is very unlikely to be reversed.

Until the last two weeks I was able to receive ITV 1 , ITV 2 , Channel 5 and all of the BBC channels on Digital with very occasional break up of picture. All from Redruth. I am at TR3 6SG. Now the ITV channels and 5 are either not there at all or unwatchable.Is this connected with the switchover and will it improve soon.

I have had no problem for over 12 months receiving Freeview with all channels, but this last week i have started having break up of signal on all BBC channels. Next door is having no problems receiving these channels on analogue. When i rang digital uk i was told i was a liar and i couldn't receive freeview until tomorrow and I know i have. I just phone them up to find out why i now all of a sudden could not receive BBC 1, BBC2, BBC3, BBC NEWS, CBBC, AND SO ON, and then to be told that i could never have been able to receive them when i know i have not had a problem before. This is on Redruth. I am in Truro TR1 1LA

We've had no BBC1, BBC2 or BBC3 on our Freeview today and yesterday. But for some reason we have BBC4. We're in Penzance / Newlyn area TR20 8TW. And we've already bought a booster for the signal. All clues gratefully received.

Friday 10 July 2009 9:26AM
D Thompson: You MUST completely reset your receiver to wipe its memory (take the aerial lead out) and then rescan with the aerial in. See if that works, Redruth has been partially switched over.

Any reason why the digital red button is not working in Helston. It was listed as one of the few things we get on the relay mast.
Briantist
Saturday 18 July 2009 5:55PM
tom osborne: Whilst BBC Red Button text can be used now, the interactive streams are on the other multiplex that you will get when switchover is complete on Wednesday 5th August 2009.

At 8:30am the ArqA and ArqB muxes are not broadcasting (UHF Ch 51 and 52). But the old (low power) MuxA and MuxD are (UHF Ch 45 and 49). This gives an overlap of Five.
Furkin
Wednesday 5 August 2009 10:34AM
Since our analogue was switched off (today 5th Aug) I can't pick up BBC1 & 2, ITV1 or Ch4.
Am I rescanning too early, or is there a fault ?
industrycynic
Wednesday 5 August 2009 11:33AM
See digitalspy for full details of Redruth.

The following are operating at high power 8k 64QAM:44, 41, 47. The following are STILL operating: the old commercial muxes UNTIL 30 September 2009 when related Wales switchovers take place. Its at the top of the DS Redruth thread. Quite confusing I know.
Jason Hulance
Wednesday 5 August 2009 11:55AM
Yes, it does seem more like a three stage DSO. This means the technical information in the "Switchover overview" above is incorrect, since the COM5 and COM6 (and NEW7) muxes are not operational on those frequencies, and we're currently in the temporary position of having Five duplicated across two of the operational (and necessary) muxes. I suppose that's not quite as bad as Stage 1 which left a lot more duplication. But clearly it would be nicer if they were a little bit more upfront about this (so that sites like this could show accurate information).
Briantist
Wednesday 5 August 2009 12:17PM
Jason Hulance: I suspect they were not so "up front" about this because Digital UK wants to put around the "red button" myth that DSO is very simple.

There does now seem to be an "inbetween" stage between now and 30 September.

"NEW7" will not come into operation for some time, if at all.

BRIANTIST:
thanks Brian.
That link is slightly different to my probs,,, but great advice for clearing the mem.
1/ Am I right in assuming that the link refers to 2k muxes ?
2/ Am I right in assuming that all my transmissions should now be in 8k ?
3/ I see different names/numbers for muxes now - is the 1, 2, A, B etc the old 2k ones ? If so, where can I see a list of the 8k ones please ?
A great site & some great help.
Thanks on behalf of other readers also.
Briantist
Wednesday 5 August 2009 2:48PM
Furkin: 1) Not sure which link. Post DSO multiplexes are supposed to be in 8k/64QAM mode, but it would appear that only the PSB multiplex have actually changed

2) the rest will follow on 30 September 2009.

3) The multiplex names are detailed here - www.ukfree.tv link icon What is behind the Freeview retune? | ukfree.tv - independent digital television and switchover advice, since 2002 - however, the Act of Parliament refers to the multiplexes by their original names still, as does DMOL.

Porthleven relay transmitter (Redruth). Retuned today and get about 20 channels. All I want to do is watch Dave! Had heard that we'll never get it.
Briantist
Wednesday 5 August 2009 11:00PM
Jo: Please see www.ukfree.tv link icon Porthleven digital switchover date | ukfree.tv - independent digital television and switchover advice, since 2002 - yes, that is a public service transmitter and will not carry the commercial multiplexes. You will, however, soon have four HD channels, if you buy a new box.
industrycynic
Thursday 6 August 2009 5:15PM
Jo: As you know Porthleven is in a dip with respect to Redruth. If your neighbours have horizontal aerials pointed towards Redruth its worth a try. By the harbour its in a dip, but the road up the hill past the church by the harbour towards Helston is on higher ground. Check for aerials towards Redruth. Lovely part of the world. Otherwise its Freesat!
Briantist

Thursday 6 August 2009 10:54PM
Just retuned my freeview box manually to each channel/mux as stated above so that I would avoid any overlap (had this issue before the 5th of August). Now they don't appear to be correct - 48, 52 & 51 are not working and appear to be replaced with 45, 43 & 50 respectively.

Either I have misunderstood the information above
or its not clear
or its wrong
or is this all to come in september when the switch over is complete as mentioned by others?
Which is it?!
Frank Hazell
Thursday 6 August 2009 11:05PM
Living at TR49BJ, about 4 miles north of Truro on high ground. Now can only reliably receive the COM6 channels whereas prior to the switchover more was available, especially PSB1. Done all the re-scans as instructed.

Specifically I am struggling to understand why I can receive from a Multiplex with half the effective power (COM6 - 10,000 Watts) and not receive PSB1 at 20,000 Watts.

My experience leads me to conclude that there are other technical factors that are not being published or that the actual output of the Redruth transmitter differs from the technical data stated on this site.

Any comments or advice would be greatly appreciated.

Thursday 6 August 2009 11:38PM
Frank H - I have just found out that my TV with in built freeview is not 100% compatible, I don't think it works with PSB1 and PSB2 (and possibly PSB3) you may have the same issue, though it did work before the 5th of August!

Thanks Garf... My STB is Sainsburys RED and is not listed for any incompatibility issues. Still scratching my head looking for a solution. Ideas anyone?
industrycynic
Friday 7 August 2009 8:13AM
Garf: The PSB's are correct for post DSO and the OLD frequencies and powers are being used for the commercial multiplexes till 30 September 2009. A big West Country/West Wales combined switchover takes place then. After that Redruth COM frequencies will be as advertised on higher powers

Frank etc: Do a complete factory reset followed by rescan. If you don't receive BBC, ITV1 etc then you may need to buy a new STB.
Frank Hazell
Saturday 8 August 2009 7:15PM
Thanks for your words of wisdom. The saga continues. Manufacturer (Sainsbury's) has confirmed the STB should be good. (as if they would say anything else).

Completed the factory reset and rescan. Manual setup shows the following when scanning these as provided by digital UK.

UHF
44 0 Strength, 0 Quality
41 0 Strength, 0 Quality
47 8 Strength, 7 Quality
45 0 Strength, 0 Quality
43 0 Strength, 0 Quality
50 7 Strength, 7 Quality

So only getting anything on UHF 47 & 50. The other frequencies show nothing at all. Have digital UK given me the wrong frequencies?

Just wishing this would end. I originally owned a Setpal which was incompatible so having replaced the STB once I am reluctant to do so again. Will be taking it up with Sainsbury's again!
Furkin
Sunday 9 August 2009 7:43AM Hayle
My (current !) problem is over. I just kept Factory ReSeting & ReScanning. After a while, I got all the channels back. It was a bit frustrating though, as I didn't know what to expect immediately after the switch was thrown.

Incy dentally: any one work with the BBC SwapOver Help people ?
I tried, but they lost my original papers and refused to help me (without payment) until I re sent the papers !? Of course, I couldn't RE-SEND 'em, cos they lost 'em !!!

Which brings me on to my next query: I'm after a reasonable STB for the new channels/power etc. Any recommendations out there please ?

Good Luck to the rest of you.
Briantist
Monday 10 August 2009 8:38AM
Furkin: The idea that a "switch was thrown" is a Digital UK marketing device, and totally misrepresents what has to be done.

Do you mean the "Digital Help Scheme"? This may be paid for out of BBC money, but it is not run by the BBC.

Any set-top box with the Digital Tick logo is guaranteed to work!

Monday 10 August 2009 7:15PM
I have a Philips digital TV that unfortunately only receives 2K transmissions, now most of my digital channels have gone. UkDigital / Offcon did not give any warning that, in addition to switching off the analogue signal, they would also be switching off 2K digital signals. I wasn't even aware there was such a thing as 2K & 8K existed. I now need to buy another bleedin' set top box, even though I had already 'switched over to Digital just under 7 years ago. (only just finished paying for the set !) :-(
Briantist
Tuesday 11 August 2009 7:56AM
Mark: There is a list www.ukfree.tv link icon TVs and boxes that do not support the 8k-mode | ukfree.tv - independent digital television and switchover advice, since 2002 of devices that do not support "8k mode".

Thankfully you can get replacement Freeview boxes for around £20. If your set is 7 years old, it probably will not have HDMI either...
Briantist
Tuesday 11 August 2009 8:32AM
Frank Hazell: What about C41 and C44?
Frank Hazell
Thursday 13 August 2009 7:04PM
Briantist: C44 is nonexistant for strength or quality. C41 is coming through with good strength but no quality. So nothing scans on either of those.

Was wondering if it was a bandwidth issue with the aerial. If I can get 47 / 50 shouldn't I be able to get 44 stronger/better than 41 as the frequencies are closer?

Will go and fiddle with alignment see if that makes any difference.

I don't have the money to buy my way through a process of elimination unfortunately. And whatever will work now may not work after the next swap around (30th Sept I think).

It really does seem that it was impossible to get ready for digital as the technical specifications and details were not widely published.

Is it just me that wants to punch the digital robot? ;p

Briantist
Thursday 13 August 2009 7:23PM
Frank Hazell: Just out of interest, do you have a wideband aerial?

The change on 30 September swaps some channels between multiplexes, but it will not change the strength of the signal in any way.
Frank Hazell
Friday 14 August 2009 3:27PM Truro
Briantist: I'm not sure but i would guess its not a wideband aerial. Its rented accomodation.
All I know is that we used to get most, if not all the digital channels prior to switchover.
Is there a way to find out specifically what was changed as I would really like to understand the problem.
Briantist
Saturday 15 August 2009 10:28AM
Frank Hazell: At a basic level the analogue channels were turned off at switchover and the digital service switched into their old frequencies at higher power.

You are not using, by any change, a single booster?
Frank Hazell
Sunday 23 August 2009 6:39PM
Briantist: Yes I am using a signal booster but have tried both with and without and I get the same channels either way. Will try again just to double check. I also found a cable splitter in the loft so will try a direct cable run to eliminate that as well.

Once I get this sorted I will detail the solution in case anyone finds it of use.
Briantist
Sunday 23 August 2009 9:00PM
Frank Hazell: Any connector can be the source of losses and interference, so it is worth checking everything.
Frank Hazell
Tuesday 25 August 2009 11:29AM
Success!!! All channels working!!

The root cause was the 3 way splitter in the loft. Which for unknown reasons was totally eliminating the signal on everything other than COM6.

My apologies to the Digital Robot!
Briantist
Tuesday 25 August 2009 1:48PM
Frank Hazell: I am sure that Digit Al (sic) will accept your apology.

I'm really pleased you tracked down the fault.

I have seen situations like this before. A friend's dad in Poole couldn't get Multiplex 2 and I removed the splitter in the loft and everything was fine.

Happy viewing.
