Why yet again have we no signals or very low signals on channels 3, 10, 12, dont know about other channels as it was three three I wanted to watch or record. Yet another retune on 22nd November 2011 which incidently started at 00.03am on the 22nd and resulted in no channel 82 Sky News 24 was supposedly going to give better TV reception. 48 hours latter and channels are down - Think Sandy Heath must provide the worst freeview service in the UK for East Anglian residents and for the people living on the perimiter. Freeview advise PE13 4AG should get reception from Midlands - you come here and try !! I have been getting good reception for several months from Sandy heath until your supposed improvement on 22nd. Some improvement with no reception! Picture breakup started at approx 20.00 hours and gradually deteriorated until no service available by 21.00 hours. Would be interested in hearing what Sandy Heath engineers have to say about the lack of signals and also other hearing from other viewers living on the North Cambs, Lincs, Norfolk borders.

For the first time in several years, since I've had freeview in fact, Film4 has disappeared. Appears fine on the EPG, but says 'tuning to new channel' & eventually no signal. This is after the latest retune - for the past week or so I've been getting misleading & annoying messages about retuning. When my channels finally disappeared I retuned & recovered all my channels except Film4 & Yesterday.
I thought the latest update was to improve the service. It is now worse than it's ever been.

@ Michael Smith - perverse though it may seem, the signals for Channel 3 and others may be better if you attenuate them. In my living room I have an HD ready TV with a PVR, DVD recorder/player and an HD Freeview STB. I note that I get ITV 1 and ITV 1+1 on the TV, PVR and DVD but not on the Freeview HD box, which receives its feed directly from the rooftop aerial. I think that the signal degrades as it goes from one machine to the next, the evidence being that the TV and DVD player, which are second to last and last in the line, do not receive those multiplexes that are still on low power.

Could somebody please explain what is going on?
After several days of messages I finally got bad pixallation on ITV, Ch4 & 5 (possibly others), so I retuned & got them back - but shifted to the 800 channel no. region.
Finally BBC1 disappeared, so I retuned & everything came back fine & in the right place.
Yesterday, as described above I lost ITV4, Film4 etc. (although on the EPG). After carrying out the retune routine above, ITV4 etc. disappeared off my EPG.
I woke up this morning to find they had reappeared on my EPG - but still unavailable. I retuned & got (allegedly) 25 new channels, but still none of the above, although once again on the EPG.
Nothing about my system has changed. From my perspective, the latest transmitter rejig looks like an almighty cock-up.

Andy: You mentioned that some channels appeared in the 800 range. This happens when they are duplicated because the reciver has picked up the same channel twice. This occurs where signals from more than one transmitter are picked up. For example, ITV1 is picked up and put on logical channel number 3. Your receiver finds another and puts in the 800s.
Crucially what this tells me is that you're in a location where you can pick up more than one transmitter. Unfortunately receivers don't always pick the right transmitter.
The fact that you are getting break-up and no signal suggests that your receiver has picked the wrong transmitter. It could be that it's picked the wrong transmitter for some channels or for all channels.
If you are conversant with manual tuning, then try it if your receiver allows.
If you would like some help with this, then I'm happy to help you. If so, then can you post your receiver's model number and your post code. The post code will help with pinpointing what other transmitters you could be picking up which might help with the composition of a workaround.

Since retuning freeview on the Sandy Heath transmitter as advised last week, we have intermittent/poor quality reception on channels 12, 15, 18, 21 and 22 (as well as a number of the radio channels). Like others that have posted complaints recently, we had great reception on all channels before retuning, so what has happened?

I'm in central Milton Keynes (MK9) and until this week received all channel at 100%. Now all MUX C channels are missing :(
I'm getting the other channels that are described as "very low" at 71% signal strength.
Is there a problem with MUX C?

Terry: If you had good reception on Mux ArqB (which carries the channels you listed) before you retuned it suggests that you might have found and stored the channels from a different transmitter. Check which frequency you are receiving the problem channels on. It should be C48 for Sandy Heath, if it is C29 you are receiving a weak signal from Crystal Palace and will need to clear the channel list and do another retune. If possible do a manual tune to the Sandy Heath frequencies. ( C24, C27, C31, C52 and C48 plus C21+ for HD if required)This should restore correct reception on all channels.

David: MuxC/ArqA changed frequency on 23rd November 2011 and is now transmitted on C52. A retune is therefore required to restore reception of the missing channels.

My HD channels are very variable in quality, some evenings they are unwatchable due to picture break-up; other times it isn't so bad (although still disruptive). Non-HD channels are ok. I've done all the usual stuff: reset box, tuned manually to Sandy Heath frequencies. Nothing seems to make any difference. Any ideas anyone?
