As mentioned by Paul, everything seems to be up and running again.

there has been some work going on in the last few days at Tacolneston. Probably this is mostly a final transmitter tuning to ensure that the reception is as intended on com7 and com8. All the other multiplexes should be fine or even slightly better than before but the reduction in the number of available frequencies has forced com7 and com8 (which have always been designated as temporary bonus channels) to lower their power. As the weather warms up there are also going to be periods of high pressure which will throw a red herring into reception problems. I think the transmitter authorities have done their best . They have no control over the amount of frequency space they have available which is allocated by government policy.
Near the Norfolk/Suffolk coast the best you can do to get Com7/8 is to use an amplified group K or B aerial or high gain wideband type . (Not the cheap DIY store wideband) . Personally I switched to freesat.

Seem to have lost some HD channels after recent retune. 113, 107 etc. Are these channels coming back?

JP:
They are still there! Maybe you do not have ideal reception or are too far away from the transmitter, or maybe do not have a wideband type aerial.

None of which explains or justifies channel 55 (COM7) being completely off-air for two-and-a-half days! Arqiva have apparently said that the cause was a cooling system failure, but it's not very satisfactory that the fault wasn't spotted until 9 a.m. today.

JP. due to the government making less frequencies available for tv (given to new radio/phone services) the transmitting authorities have been forced to reduce power for tv groups (multiplexes) com 7 and com 8 which carry channels like BBB4 HD and BBC news HD. So in some areas viewers may need a wideband and/or amplified aerial for these channels.

Those services are in the COM7 multiplex, which was completely off-air from Tacolneston from around lunchtime Friday until about 10 a.m. this morning. If you retuned in that period, it explains their loss. Try retuning again now the transmission has been restored.

Still no joy for me with COM7 and COM8 through my BT Youview box.
However no probems at all with them with the aerial plugged directly into the TV.
The readings from the TV for BBC1 HD is 95% quality 100% signal.
The readings from the TV for BBC News HD is 62% quality 100% signal.
The readings for BBC1 HD from Youview is 100% quality 96% signal.
Cannot supply figures for BBC News HD through Youview as it won't tune in.
I have another aerial for the kitchen that used to point at Tacolneston but now points to Sudbury. This was in the low power days and Sudbury was very patchy. In comparison Tacolneston was good. The quality and signal levels in those days were much lower than todays and the picture did get interrupted by the fridge motor. The point I'm making is, I could always pick something up despite much lower signal.
The one thing that I notice when I call up BBC News HD is it always has a slight delay before the picture comes on. Thereafter it is fine. I think these Youview boxes don't give their tuner enough time to lock on to the channel. This is something that could be easily resolved with a manual tuning option.

DJB: If you have 100% signal strength you may be overloading the tuner with too much signal. Try fitting an attenuator to reduce the signal strength.
