The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Tacolneston (Norfolk, England) mast?

Yes the council did ask people in flats what they wanted but they never asked those in houses. Never told us it would be cut off.

Dave, thanks for the advice. On my Samsung tv I went Menu, Antenna, Manual Tuning, Digital Channel Tuning then hit the red button to add a new Channel. I selected Channel 62 and then Search and it added the 4 HD channels. Success!

Have lost nearly all channels.
ITV (Ch46) is at 30% strength (which is <50% of immediate post DSO) but Ch55 is 0 - 2%, Ch45 0%.
What on earth is going on? This is worse than pre DSO and is totally unacceptable.
Is there a transmitter fault?

Update
Signal strength now increased on Ch55 to 35% (c.50% of normal) but every few minutes drops to zero for a couple of seconds before returning to the same level as before.
I suspect a transmitter fault because all channels are now running at 50% of previous power and I don't believe it's atmospherics. Brian?
(My son in Langley - I'm in Dilham - reports 100% ss but that was some time after we lost everything.).

Ch55 now showing 72% ss so it must have been a transmitter fault.

Using my Humax HDR Fox T2 PVR I get a set of broken white lines across the top left hand side of the screen on ITV1 & ITV 1HD only. they don't appear using any other tuner.
Anyone know the cause?

I live on Thorpe Park, in Norwich and prior to the switch over had all freeview channels. Now it seems I cannot recieve things on COM4 and COM5.
I have a wharfedale DV832BN freeview box and our aerials (on the flats) were all re-done last year (so people could have the option of sky).
I have spent ages scanning these helpsites etc and can't seem to find an answer that I can make sense of! I have also re-set, re-scanned etc several times.
Does anyone know (and willing to explain to a non technical type) what this may be down to- is my freeview box likely to be outdated, or is it more likely an aerial thing?
All help greatfully recieved.

Blackcat: I am thinking that it might be an issue with the aerial system; not a fault, but due to different frequencies being used that weren't used before.
Is this a block of flats with a single aerial or do you have an aerial each? The latter is unlikely.
The multiplexes (groups of programme channels), e.g. COM4 and COM5 each have their own frequency. With TV, we usually refer to the frequencies as (UHF) channels 21 to 69 (not to be confused with logical channel numbers on a TV, 1=BBC1, 2=BBC2 etc).
Analysis of what Tacolneston used before switchover and what it uses now shows that COM4 and COM5 are on two channels that are a bit lower down than those used before switchover.
Pre-switchover, the five UHF channels used for analogue were 62, 55, 59, 65, 52 and the six digital ones were 63, 60, 53, 58, 61, 64.
Post-switchover, the six digital channels are (in order) 55, 59, 62, 42, 45, 50.
COM4 and COM5 are on Ch42 and Ch45 respectively, which is lower than those used before switchover. I suggest that this could be an explanation for the cause of your problem.
Your aerial system might have been set-up to allow the frequencies used previously through (from the aerial to your aerial socket).
If it is the aerial system that is not supplying the COM4 and COM5 signals to tennants, then only adjustment of the system will fix the problem and that is the responsibility of the landlord rather than the tennant.
Whether the above hypothesis is the reason for the problem is probably largely irrelevant as far as tennants are concerned. The responsibility probably lies with the landlord.
You could ask your neighbours if they have the same issue.
I also suggest that you try manually tuning in these two multiplexes (if your box allows manual tuning).
