The Code Rate for com8 was reduced to 1/2 a while ago.

Here are the current Bitrates for com7 and com8:

PCRs in each transport stream were used to calculate the bitrate.

Median values tend to eliminate rogue PCR results.

The values can be used to deduce the transmission parameters using a calculator such as:

DVB-T2 Data-Rate Calculator: DVB-T2 Data-Rate Calculator - Tools for Digital TV and Mobile DTV

Hi js, > The Code Rate for com8 was reduced to 1/2 a while ago.

It's believed this happened on the 12th Feb. when Sandy Heath and a few other transmitters had a retune, it was spotted on the Freeveiw Detailed Coverage checker for Sandy Heath reception and supposedly upcoming changes on WH on the 20th, and later dates for other TXs, but it seems they all must have changed on the 12th as one might expect because it's an SFN. Checking here on off-air it hadn't changed on the Monday (10th) but had later in the week!

Oh, forgot to add a lot of the (DUK) database has NOT been correctly updated. Many TXs still showing 2/3 for COM8 in the Detailed Coverage Checker.

Chris.SE: Yes, I saw the report on DS. They might have changed simultaneously but com8 is not in the SFN yet. In fact, it has a Cell ID of 2369 which is the same for all the multiplexes that originate from Winter Hill apart from com7 which has Cell ID of 16449.

The Cell ID is shown in this screenshot from CrazyScan2, taken the morning after reading the report. I'm not sure what bitrate CrazyCat shows here but the parameters are correct.

Hi technically you are right of course, I could have worded what I said better - instead of "because it's an SFN" it might have been been better to say "because they all will be/or are part of an SFN it's sensible/necessary for them all to change simultaneously"

All:

For anyone visiting here that has lost and doesn't realise what has happened, there has been a retune event.
The PSB1/BBCA has moved to UHF and the COM8 multiplex to . You need to retune to restore your channels.
If you are having trouble getting the BBC channels in their normal place at LCNs 1,2,9, .......etc in the EPG, this could be because you have an old C/D group that is not receiving C32 very well or at all. Some of these aerials will work ok if you are in a good area. Otherwise you now need a Group T/ aerial to receive all multiplexes from reliably.

For those having problems with the BBC multiplex on C32, you can still find the old programmes/channels at LCN751, 752..... in your EPG until the 22nd April to give you time to get your aerial problem resolved without loss of service. See Problems with Freeview reception? | Help receiving TV and radio and click on work affecting television in the North of England on the 19th and 20th February for more detail about these changes.

If you don't have or , and use your own aerial (not a Communal or Landlord's one) then you can get free - phone on 0808-100-0288.
See What is 700MHz clearance? | Freeview for technical information about these changes.
For further information about these Winter Hill retunes and channels used, see my posts on 12th/13th Jan et seq. on p189 here.

ON instructions on our tv I have tried all day to re-tune the tv, however all the BBC stations have been not available. At 6pm there is a very weak when I do a manual tuning.
When will we have a good signal as we had previously?

I happened to have a decent external Group T fitted in Tuesday 18 Feb as part of repair works, and was getting good signals (~80% strength on ch58(COM4) according to my PVR's , similar on other ) immediately after installation, and I had no problems with recordings made on Tuesday or Wednesday, including some from COM4. My location is BB8 7DS (Colne, right on top of a hill).

Today (20 Feb), both before and after retune, signal strength is more like 40% on ch58 and most other channels, though ch32 is more like 65%, and recordings made from ch58/COM4 after the retune are showing some patches of mild breakup (kind of expected at that signal strength).

Have the power outputs been [maybe temporarily] lowered as part of the retune process?

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
