Stephen Hall: You're in an awkward location that's between three main transmitters, but the terrain blocks line of sight to all of them.

Your best option will be Sutton Coldfield once it switches over in September. Sandy Heath is expected to continue to be poor, for you.

You're quite close to the Dallington Park relay, but again it's the wrong side of a hill, and the radiation pattern is restricted in your direction.

If you're currently without TV at all, you could try Sutton Coldfield now. You're unlikely to get reliable digital service, but you should get reasonable analogue pictures: the problem here is that digital power levels are relatively low at Sutton Coldfield (and at Oxford, the other alternative).

If you're insistent on Anglia news, you'll probably have to look into satellite.

I retuned my freeview box on the morning of 13th April and I was delighted to see that I could receive Yesterday and ITV4 perfectly. However, when I returned home in the evening these channels had gone, i.e. no signal. I just wondered why these worked fine in the morning and had disappeared by the end of the day.

Ian: You are probably on the fringe of the reception are for ArqB, due to the low power output until 14th September 2011.

But, also see Single frequency interference | ukfree.tv - independent free digital TV advice .

Hi, NN9 5ND
Have retuned my tv (which has Freeview tuner built in) several times and the strength and quality of the signal is fine, as is the picture.
My only problem is that I am not receiving the Freeview HD channels.
I see on the channel guide on my tv that channel 52 is yet to be allocated.
Can anyone help as to if the HD channels are being broadcast or do I have an equipment problem.
Regards

Mick: The HD channels are being transmitted. Most likely you have an 'HD Ready' rather than a 'Freeview HD' TV. Please see What does "Full HD Ready" actually mean? | ukfree.tv - independent free digital TV advice for more information.

Maz: As above "The commercial multiplexes at Sandy Heath will remain on their pre-switchover channels and powers for a period after digital switchover. SDN will then temporarily move to channel 31 (at 20kW ERP) on 31 Aug 2011, before adopting its final allocation of channel 51 on 18th April 2012. Arqiva A will adopt its final allocation of channel 52 on 23 Nov 2011. Arqiva B will temporarily move to channel 67 (at 20kW ERP) at switchover and then it will adopt its final allocation of channel 48 on 14 Sept 2011"

We have experienced "sound drop" on some freeview boxes (metronic) since the "Switch over" can you advise if this is down to various tests and changes over this period as we have consumers complaining that there products appear to be faulty.
Please can you advise officially what the status is and when things are going to be "set"
Thanks in advance

Andy Hicks: I would see Freeview intermittent interference | ukfree.tv - independent free digital TV advice but the most likely explanation is you have too much signal.

If you have any boosters or amplifiers, remove them from your system. If you don't you may have to fit an attenuator.

Why are tuners not equipped to recognise and deal with a strong signal?
