...Thinking about it, could it be co-channel interference from France?

The whole of MUX-C has gone walkabout again. Everything else is fine but C is non existent and has been all day.

Solent Viewer.I would look up inversion effect.Also there is a possibility as you mentioned that Rowridge's Mux C on channel 37 may have been temporarily swamped by the analogue Channel 5 signal from Crystal Palace.It is a possibility !

Solent Viewer.What i forgot to add is that the analogue Channel 5 signal from Crystal Palace uses channel 37 as well !

jb38 I think you are right about not getting Hannington on the old Tosh. Here in Winchester we can get both Rowridge and Hannington, and looking at the signal strength I think I was probably getting Rowridge (after DSO1 but before DSO2)from the back of the aerial pointing at Hannington, rather than anything from Hannington post DSO2. Anyway, the Tosh is now definitely for the tip, and many thanks for your knowledgeable and timely advice

Solent-Viewer I think Roweridge has been having intermittent problems since Monday (the 12th.)

On that Monday afternoon (14:00hrs) I was watching a film on 4+1 and after about twenty minutes started getting pixelation and the 'no signal' warning problems forever appearing. I thought it was just that channel but after about five minutes I flicked through every station and found everything was screwed up in a similar way (and the only channel I could get was Film 4.) I had to give up watching but left my set on and checked it from time to time and at around 17:00hrs everything was back to normal.

Now weather would not have affected every channel with interference as I experienced it and my belief is something is wrong with the transmitter and they try to fix it outside of peak time viewing which is why you could well be having some reception problems.

I may be wrong..and if I am good..but my feeling is all will be sorted out come the next retune on the 21st..we'll see.

Just thought I'd mention my experience in view of your troubles.

Colin T: Thanks for your update, as I am always extremely interested to know the outcome of situations such as yours, and with this irrespective of whether or not it might confirm my suspicions about the cause of a problem.

Its a bit unfortunate about your Toshiba as its one of the brands I rather approve of, but it would still make a good monitor if used with a cheap Freeview box coupled into it via a scart lead, or alternatively it being used on its analogue setting to view a Sky boxes RF modulators output.

Anyway, much obliged for your update.

Regards / jb.

Hello, I am in Dorset, near Wareham. Since the change to full digital early March, I am expediency many reception problems I didn't have before. Loss of quality on all BBC channels, no signal popup showing forever on some days, pixelisation, jerky image and sound. On the day I retuned, all seemed fine, the problems started on the next day. I have a topup TV account with a dedicated box that shows all channels, with the loss of quality described earlier. My TV set is less than 3years old, with all the modern trappings, but I have lost half of the channels on the day after retuning. (it was showing 125channels on that day). For several days I had 0 channels on the TV set. I Have lost most BBC, ITV, channel 4, 5 etc. I fail to understand why on the d day it was fine to subsequently end with the loss of reception? Can you help?

Kim V: Could you give more information with regard to which transmitter you should be using, your postcode would be most useful so that a check on predicted reception can be made. If you are using Rowridge remember that it is only the standard definition BBC channels that have switched to high power working at this stage. ITV1&2, C4/C5 etc follow on 21st March 2012 (and HD channels start too).The COM muxes switch to high power working on 18 April 2012. The Wareham area receives rather patchy coverage from Rowridge, Mendip, Stockland Hill and Hannington so it is possible that you might have found signals from a different transmitter to the one that your aerial is pointing to, resulting in unreliable channels being stored.
