roger: If only the BBC channels are being affected then carry out a signal check whilst on the BBC and make a note of the mux channel being indicated as BBC from Brierley Hill is on mux Ch60, if though mux Ch43 is indicated then your TV / box has stored the BBC from Sutton Coldfield.

roger: Have you confirmed that your receiver is tuned to the correct transmitter for BBC services?
Bring up the signal strength screen. If your aerial is directed to Brierley Hill then it should be tuned to UHF channel 60.

We live in Worthing (BN11) and in the last couple of weeks have found that we have bad interference (very blocky pixellation and digitally distorted sound) on ALL freeview channels.
Previously we've had occasional problems (which I believe are weather related), but this now seems to be continuous.
We have a roof mounted digital aerial correctly aligned to receive from the Isle of Wight transmitter and only one TV in the house.
I have tried connecting in a booster to the signal, but even when the TV's menu system is telling us that signal quality and strength are both 10/10, we still have interference.
Is it possible that the TV itself has a problem? It is a 5 year old Panasonic TX26LXD600. (BN11 an)

Duncan: Interference of the nature you describe is nearly always accompanied by fluctuating quality being seen when viewed on the signal check screen, the fact of you having a 10/10 indication suggesting that your signal strength is excessive.
Purely for test purposes, try removing the booster again and allowing the signal to drop under the 10 level thereby allowing you to obtain a more accurate check on the stability of the signal quality, further info dependant on indications seen.
By the way a (1) was missing from the post code entered, this having placed you at only just over 1 mile away from the Whitehawk Hill TX and so I used Worthing Post office as a test code.

Moved to Cambridge six weeks ago. All fine at first but no hd channels as before. Then began losing 5...5 US itv 3 itv 1+1 even Sky news. This is spasmodic but also get problems from planes. Any suggestions?

Sandie Blickem: Queries of this nature cannot really be answered unless more info is provided such as a post code or one from somewhere nearby like a shop / post office etc.
It would also be of assistance to know what type of aerial is being used, e.g: whether roof, loft mounted or communal?

Ref my comment Sat 18 May, I have now discovered that it seems to be our DECT phones which cause the very bad interference on all freeview channels when they are in use. Is there a filter that we can use to stop this?

Duncan: Modern DECT phones should not under normal circumstances interfere with with Freeview as they operate on far higher frequencies although non specific frequency digital noise will always be radiated by them, and so the question would be, does the coax from the aerial run anywhere near to the base station or cable to land line from latter? or even one of the handsets should you use same.
The other point I wondered about was if the interference starts as soon as you activate the handset but before dialling a number? if it does then what happens if you disconnect the line from the base station that connects into your landline, because if it stops when you do that then a ferrite ring might possibly cure it, details of dependant on reply.
