Suzy: Yes, sorry I forgot all about that event, maybe you could give an update on your findings after you have carried out the "dreaded" retune as I would be most interested know the outcome and which hopefully is favourable! or on the other hand maybe not as the case may be, and should be any remote chance it be the latter then carry out another retune about an hour or so later. Various things are happening then, but to my knowledge the main EPG channel moves are as below / Dave (from 19 to 12) Yesterday (from 12 to 19) Really (from 20 to 17) Gold (from 17 to 20) Food Network (from 49 to 48) Jewellery Channel (from 60 to 49)

Suzy: I am unaware as to whether or not you have managed as yet to carry out a second rescan, but just purely for your info the other programmes that are also on the "same" transmitter as Yesterday (19) are Film4 (15) / ITV4 (24) / Ideal World (22) and Argos TV (55).

I have performed retune (auto and manual)(Sandy Heath on 20 and 21.9.2012) and my BBC1 and 2 are now on Channel no 800 and 801; why?

Mick I think the only way is to do a 'factory reset' and then a Manual tune of the 6 channels you need on Sandy Heath. The channels for that transmitter are 27, 24, 21+(HD), 51, 52, 48. If your equipment does not handle HD then you can leave out Ch21+.
I've had this nightmare with the retune this week too and Manual tuning is the only way round it. Hope that helps, Mike.

Hi - I live in Buckingham and have had poor signal/no signal on a number of primary channels over the last few days. Doing an auto-retune has not helped. BBC1 and BBC2 are disrupted again this afternoon (of Monday the 24th September). Coverseley ITV, Channel 4 and Channel 5 are fine. Any advice please? Many thanks!

Hi Ian,
According to the map you should be beaming SSW to Oxford and receiving your signals on Channels 53, 60, 57 (HD if required), 62, 59, 55. No reports of problems with this transmitter.
There's a chance that when you Auto retuned you picked up a different transmitter which may account for your weak signal on some channels.
Do a 'factory reset' on the unit and a Manual Retune to just those channels and all should be well. You may need to refer to your User Guide to do that.
Hope that helps,
Mike, retired Radio & Electronics Eng.

Hi MikeG (in the hope you are picking up)...
Many thanks for your reply. However, all the aerials on my estate in Buckingham point to Sandy Heath, more or less the opposite direction. I think Oxford is 3 or 4 miles nearer but, because of land mass and buildings, we've all found Sandy Heath to be the stronger signal. In my case, an engineer measured the signal strength on a couple of occasions. Any other thoughts? Again, many thanks.

Hi Ian, if you are on Sandy Heath you need to do a Manual Tune on channels 27, 24, 21 (HD if needed), 51, 52, 48.
I'm on Sandy too and there have been no problems that I've noticed, so chances are you've grabbed a few extra wrong channels instead; maybe from Oxford off the back of your aerial; not unusual. Hope that sorts it out.
Mike
