Hello Brian,
No. You used to list the conflicting signals and specifically state that (for example) on channel 51, the signal from Hemel Hempstead would be stronger than the signal from Oxford, meaning that the Oxford signal would not be received. The above link isn't as useful in this respect, as although it shows in detail the signal strengths, it doesn't say where one signal will overide another.

Nicholas: I see what you mean, let me have a think about how that might be shown. The problem is that it depends on where you point your aerial...

Mike Dimmick. Thanks for that advice, you may well be right and I will certainly try it. I have got a powered splitter so I'll begin by changing it to an unpowered one before putting in an attenuator. Then wait on the final switchover to see how all channels are. Thanks again

I live in Swindon, SN3 4UX, and my freeview signal has gone for the likes of BBC1-4, ITV,2, CH4...
This appears to have happened since Monday 12th.
Is there work going on to cause this?
Cheers.

Have been unable to watch freeview since last Thursday and was hoping that the problem related to switchover interference etc. Live in ox14 4ax and have roof aerial. Have been in to loft and no obvious problem with cables. Labgear distribution box is on as is power light to masthead amplifier. Sky is watcheable in all rooms via analogue but remaining analogue channels are poor with thick white band moving up the screen. When retuning today my old kitchen tv, using Phillips freeview box, found c71 freeview channels but signal strength was 5-15% with signal quality always being max of 30%. No picture or sound on any channel although program details are shown. Our toshiba tv with integrated freeview tuner does not find ant channels. Was wondering whether it was worth waiting until after next switchover date, 28 sept, before calling out aerial installer again? Views appreciated.

MH: I would have a look at Freeview reception has changed? | ukfree.tv - independent free digital TV advice - the problems you have are nothing to do with the switchover.

Mike Dimmick. I have now tried taking out the powered splitter and have the aerial plugged directly into the freeview box (humax PVR). I had to manually tune again to get the oxford channels as it still wanted to pick up the Sandy channels first. All channels seem ok and are showing 100% quality and about 80% strength except the Mux A channels. It is not finding them at all and showing the signal strength and quality often jumping to '0' or very very low. So it doesn't seem that the splitter box made a difference.
I've checked the frequency which is set at 714000 but can't think of anything else to try. Do you think it could be the aerial direction is slightly wrong?

Hi Brian, I assume the main BBC multiplex (BBC1, 2, news 24 etc) has migrated to ch53 this morning AND boosted to full post DSO power already. If so I need to turn the wick down on the booster - my tv has found the signal but wont display the channels so it must be too strong - postcode ox9 3je
