Ah well - one extra HD channel is better than nothing. Thanks again for the response.

30 December 2013: the site says all is working, but I have no signal on 4 of the 6 multiplexes. Channel 41 and 44 are working, 47 56 58 and 60 are not. They were all OK yesterday.
Is this a strange fault in my aerial, or has nobody realised yet that tose transmitters are off?

Keith: Its impossible for anyone to make comment on your problem or offer any advice if they are unaware as to your location albeit it would seem to be in the Sudbury area, the location preferably in the form of a post code or at least one from somewhere nearby, e.g: a shop / Post Office.

Following from Brian's answer of 7 December , we may have lost the Freesat red button HD but I can't find a red button SD. Has Freesat totally lost a red button facility?

Here at Aldeburgh in a high location, I have a large areial which receives all muxes with signal strength/quality at least 95% from Sudbury. I do not use the Aldeburgh transmitter due to the limited number of channels In summer, one or two muxes often come up'no signal.' I think this is due to the Dutch.
Now, though, one or two muxes are again showing 'no signal' from time to time, and the Dutch are not interfering. Any ideas as to cause? Sometimes the BBC/ITV muxes go, other times other ones.

Please would someone explain how much signal and how much quality, percent, is required to to display a good picture which does not pixellate?
Also, why on many occasions do I not get any pixellation, then suddenly, 'no signal?' When I check the strength and quality they have moved from their usual 95% to zero.

Nick : If indeed you are presently located at Aldeburgh then according to the terrain indicator you do not have a line-of-sight with the Sudbury transmitter as seen by opening the undermentioned link, therefore the signal you receive from that station is purely via diffraction, i.e: signal bending around obstructions.
Reception under these conditions is always vulnerable to problems relating to weather conditions and the effect it has on the surface of the terrain as far as its reflective properties are concerned, plus of course the effects of any atmospheric condition changes that may be in evidence at the time, all of generally causing the signal level to gradually drop off to the extent that it starts to encroach on the minimum level required for the digital receivers decoder to operate correctly, any further reduction taking it under this level whereby reception suddenly vanishes giving the impression as though someone has done something, or even that the transmitter has failed! albeit that the signal is still there.
I suggest that the next time whatever you are viewing vanishes you should immediately go into the TV or boxes tuning menu / manual tune and enter the mux channel number of the programme being viewed but with this action NOT being followed by pressing search or scan as not doing will cause the TV or boxes tuner to act like a signal meter, the indications from same being noted for the purpose of cross checking with that obtained when reception was OK.
As far as levels are concerned, its not really possible to give levels with any sense of accuracy as it all depends on the calibration of the equipment being used, hence vast variations in levels can be experienced.
However, on the older Humax SD boxes such as the PVR-9200 / 9300 a signal strength level of around 70% coupled to a 80 / 100% quality could be considered as being good.

I live in Thorpe-le-Soken, which is shown as a fringe area for Sudbury digital transmissions. However, with a high gain antenna and masthead amp it is OK.
I have a problem with routing Sky to other TV's in the house using RF2 output. I get vertical striations on the picture due, I believe, to adjacent channel interference. RF2 is tuned to channel 68 currently. Any suggestions for a better channel to minimise the problem. A final point. The striations vary in intensity and seem to be worse in the evening.
Any help appreciated.
