John rye: Your missing some muxes, so check that TV is actually locking on to that transmitter. And check signal strength - could be that the aerial lead to it has a problem - try swapping them over.

BBC4 HD if often at lower strength than ITV, but if your missing both, it cant be the transmitter - it either works, or it doesn't.

SANDY HEATH transmitter - Possible weak signal [DUK]

a quick thanks to jb38 as I was indeed having some problems from my digibox retuning to the wrong transmitter. when my reception of ch51 and ch52 is poor it sometimes retunes com4 and com5 to ch42 and ch45 (Tacolneston, perhaps).
I've retuned now (2 or 3 weeks ago) and keeping an eye in case it retunes again - but of course if the signal was good I wouldn't have the problem.

Quick update, I am in Peterborough (PE3), since early June my Com5 reception has been a couple of seconds of picture followed by longer gaps of no picture. Sometimes Com4 is affected too but the other muxes are fine.
But last week things changed ...and went on changing
Sunday was the same as it had been.
Monday, it was fine (except for occasional very small glitches)
Tuesday, the problem returned to com5.
Wednesday, occasional brief picture loss on com5 but the quiz shows on Challenge were watchable
after that ... virtually nothing on any of the com5 channels (so worse than before)

John King: I'm in Peterborough as well, but on Waltham. Check the signal levels on all the muxes - Com 5 should be about the same as most of the others (Com7 is certainly weak).

The most likely problem is somewhere in your system - perhaps a frayed cable, loose join, etc. Cables can be odd, and a problem might mean a really strong mux is wiped out, but a much weaker one is OK. Simply changing the aerial lead isn't a bad idea - they are cheap, easy to change, and if there is no difference, then at least you know its not that.

If there is still a problem, then you'll have to check up the signal path - good luck!

Hello and please help! I live in the NN3 area and our freeview signal (assume from Sandy Heath) has gone from excellent (with no problems) to completely pixelated in the last couple of weeks. Several re-tuning attempts haven't worked - in fact, signal strength is excellent, whilst signal quality is poor - which I thought was odd. Another website mentioned about removing booster boxes so am going to try that next.

I really don't want to have to call an aerial company so would appreciate any thoughts on what to do...

Stephen Kightley: See the page 'too much of a good thing' - the fact that you have a booster sounds about right for too high a signal.

Since the power cut in the Ely Cambs area on wensday we have lost every thing but BBC 1 & 2, bbc4 and the radio channels and children's channels.
I have retuned and we would appricate any help.

Andy: Provided that your TV or box was not in the process of updating when the power dropped out? then you shouldn't really have lost anything, however as you partially have done and with retuning not having rectified the problem, try carrying out a full reset on your receiver, this on some models called "first time installation" / "default setting" etc.

That said is on the assumption that your Freeview reception is from the Sandy Heath transmitter via normal aerial system (not communal), if it isnt? then a post code will be required for signal strength assessment purposes.

Really bad reception over the last three days. Picture breaking up or no picture because 'no signal or weak signal'. Atmospherics may be partly at fault but can anything be done about the strength of the signal. We are in North Cambs PE13 5LB and prefer East Anglia to other transmitters.

J Knights:

It is not an issue with signal strength or quality from the transmitter but a perfectly natural and well known atmospheric phenomenon that no one can change. Your best solution is patience. The high pressure that gives rise to this tropospheric disturbance is predicted to move away from around Thursday so everything should come back to normal after then - unless you have tried to retune your equipment. If you have done that, wait until at least Thursday before retuning again to recover the lost channels.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
