In the Ipswich area, you get similar powers from Tacolneston and Sudbury and the aerials are often pointed depending on geography and the positions of local trees, so what you are saying isn't a big surprise.
Your problems could still be cured by improving your aerial setup.
Firstly, the leads from wall sockets to the TV can make a big difference and are the simplest to fix. If you replace cheap leads with good quality double-shielded cable and decent connectors, that can often make the difference between a borderline digital signal and something that's viewable.
If that doesn't sort out your system, the next thing to bear in mind is that you probably have one aerial and yet you have at least 2 TV connections. If the splitting is carried out with a cheap connection, that will also cause problems. The best type of splitter is called a 'diplexer' and should be labelled that way. Unfortunately, such things are often buried away in the loft/airing cupboard/floorboards, so it may take a bit more time to find out.

hello Norm de Plume
Thanks for your help. Not sure where our "diplexer" is, as we have an external aerial cable that runs from the roof top aerial over the roof and down the back wall to the back of the house and then comes in through the wall into an aerial socket in the dining room, and another cable that runs from the aerial over the roof, down the front wall and into a socket in the front room. I'm too old to climb up on the roof and look to see if the splitter is up there!! Still unsure as to why my new cheapish JVC telly with built in tuner works fine on both aerial sockets, but the Humax box is, quite frankly, a pile of manure. Surely if it was a problem with the aerial lead (either indoor our outdoor), would it not make the digital reception on that a load of old pants too?

Elaine Fuller: To be quite frank about it, the Digital UK trade reception predictor doesn't really indicate good reception being possible from anywhere associated with your post code, with the only slight glimmer of hope being on the 23rd of November from Tacolneston, however this being short lived by going downhill again in June 2012.
In areas such as yours where aerials can be seen pointing in various directions, is always (and without exception!) an indication of an area of erratic reception where signals are capable of changing strength within a few yards of each other, needless to say nothing can be done about this, as areas like that are really what Freesat was intended for, or partially anyway.
As regards your JVC TV Vs the Humax box, Humax boxes are amongst the best for reception sensitivity and stability as far as glitches are concerned, and when you say that the Humax was poor compared to the JVC are you sure they were both receiving from the same transmitter? as judging by what you have said I feel that your reception area is possibly even worse than the trade predictor has forecast.
When you are carrying out experiments with reception, "always" check via the devices tuning menu / signal strength / quality indicator that each device is using the same Mux channel for whatever you may be looking at, this just in case they aren't! and something which is not beyond possibility at your location.

Hello Elaine,
It sounds like the splitting is done at the aerial.
Do you know if any power needs to be sent to the aerial from a box of tricks somewhere or one of the receivers? If so, you might have an amplifier on the aerial, so the splitting would be electrically of a good quality. Unfortunately, if not, it could well be that the wires are both just joined together at the aerial and that will lead to a lower quality signal. The reason that I suspect the aerial installation is because the Humax is giving problems - Humaxes should give you a good picture but if there's something wrong with the wiring, that would lead to unexplained results.

hello Norme de Plume and jb38
Just to say huge thanks for all your assistance on this. Being a technological idiot it really is good to be able to talk to folks who know what goes on! I did however, have a minor brain wave last night and went and bought a decent scart cable (Monster, £34 from Comet), and replaced the cheap and nasty one that had been supplied by Humax. Lo, it seems to have worked! (I'm saying this with all extremeties crossed!!) The Humax was only set up with its new Monster cable last night, and it seemed preettty good all evening, only interference was a slight stutteriness on picture, but no loss of sound, when the local gang of young mopedists roared past at 5 miles an hour. Am hoping that this is the miracle cure. Once again huge thanks for assisting a ranting, technophobic old bird! :+)

Elaine : have been following this for a few days. There is no way the problems you reported, which all sounded related to reception, could have been fixed by a new SCART lead between box and TV. But, hey!, if it's working now that great!
(£34 for a SCART though : I'd expect the PVR for that ...).

H, I live in CB9 which although is listed in the Sandy reception area the east side of the town in general looks to Sudbury. Last Christmas in anticipation of the comming digital switch over I purchased a Samsung BD-C8200 Blueray/HDD/Freveiw HD box. After the switch and necessary retunes I'm not aware of anything missing, possibly gained a couple of extra channels, but no HD. My question is. Should I be seeing some HD now?

Gary Dadds: The trade reception predictor indicates that you should be receiving a perfect signal from Sudbury on Mux Ch47, so I would try a manual scan on this channel.
If still nothing, then try the same test but on Mux Ch21, that being Sandy Heaths HD service, as although it doesnt indicate such good reception at least its still in the predictors green zone. (good!)
