Had nothing but trouble with picture break up & keeping getting "Weak / No Signal" coming up. Have re-tuned a number of times - no better. Aerial on roof high up.
Digital has been a complete joke forced upon us. What do we pay our licence for - B.B.C. executive salary increases?

Same problems as people above, weak signal for the last two days.
If it is just atmospherics then please us!
Is it too much to ask for an explanation?

During the summer months I was able to receive all the free view channels without any problems.
Since the latest engineering work on Sandyheath, my television reception has been terrible. The signal strength remains very high at all times, but the signal quality is zero a lot of the time. The BBC mux is most affected, but the interference moves across the band.This sound like massive multi-path interference .What have they done to the Tx aerials or are they playing with the linarity of the PAs?

Sadly folks it's just interference due to foreign stations coming in strong. Happens on Digital signals just like it did on analogue terrestrial TV in the past when you used to see two pictures at once.
This type of interference usually happens when the barometer reads between 1025 and 1030mB; a little unusual to happen at 1010mB, the current pressure. As soon as the high pressure system moves away all should return to normal. However it looks to be with us for at least another week according to the forecast. If, like I, you also have Freesat that isn't affected. Mike.

MikeG: Sometimes the culprits are UK transmitters in adjacent regions! A look at the William Hepburn's Tropospheric ducting forecast charts will give some indication of which transmitters could be sending signals way beyond the normal coverage area. The Rowridge transmitter is co-channel with the Sandy Heath PSB muxes and Emley Moor is co-channel for the COM muxes.
