Strictly was ruined tonight. Complete blackout for several minutes at a time. It hasn't been this bad before.

Soham (CB7) Lots of pixellation and several 'No Signal' events on Ch4 between 21:00 and 22:00 (The IT Crowd - only saw 1/2 of it). Seemed to be worst on the ITV/Ch4/Ch5 multiplex, BBC seemed better.
Had some pixellation over the last few weeks, previously rock solid, completely useless tonight!

In Peterborough PE3. All this week our TV has been virtually unwatchable with either pixilation on most channels but more often on BBC and/or complete loss of signal.
In 6 years we have only had this problem once before just for one day.

Aerial is high above the roof. It was installed specifically for digital signals and points at Sandy Heath.
The problems only started this week.

Freeview bad or non existant on Sandy Heath tonight from 21.00, of course I can receive the shopping channels and other irrelevant material but no BB1/BBC2, Ch4, ITV1 etc, cannot find any contact details for transmitter info or engineering assistance, generally very disapointed with non subscription services, cable not even an option in my Village and would have Sky
Looks like a conspiracy to make us all buy Satellite systems.
Everything on the PSB1 and 2 Mux is 15% or less signal strength, missed on program I especially wanted to see, and missed the 4+1 repeat as reception broke up again at 22.18, I am a an ex TV Engineer and I know what I am talking about, service is currently not worth the TV Licence

CB24 9NU Using wide band aerial on roof to PVR then via Scart to TV. All used to work normally. No new hardware. Now some multiplexes no good especially BBC on ch 27. Can view signal on PVR. It gives "Strength" & "Quality". Some example numbers: ch24 S=60%, Q=0 or 10%; ch 52 S=61% Q=100%; ch51 S=61% Q=100%; ch27 S=58% Q=0; ch48 S=61% Q=100%. So the higher frequencies have more strength, but not that much more. Does the low quality on the others (unwatchable) indicate interference? Any ideas gratefully received, family are unhappy. Disenchanted with digital broadcast!
