Thank you for the replys
I tried a manual scan on channel 47 and received no results. As a check I did a manual scan on Ch44 and got 31 hits. I get 91 programs altogether with an auto scan, my tv finds 104 although it doesn't have an HD tuner so obviously doesn't list the HD channels.
I also tried a manual scan on Ch21 to see if I could pick anything up off the back of the aerial but with no results.
I must admit that I do have suspicions about the Freeview HD box. I think I need to either find someone local who is recieving HD and try my box there or take it to my parents who are getting HD off of Sandy.

Gary Dadds: Yes I think it best for you to try it as you have suggested at your parents house, and in that case its Mux Ch21 that will apply for Sandy's HD service.
I tried, but failed, to get more detailed technical spec info on your box, as I have to admit that I also was a bit suspicious of your box being the problem based on what you had originally said, albeit it is advertised as having an HD tuner.

thank you for your help looking at the aerials near my house most of them are pointing towards crystal palace accept for my neighbour who had a new one fitted and its pointing towards blue bell hill from what i can gather looking at the coordinates, would it be better to alter the position of my bigger 91 element aerial towards one of the London transmitters and put my newer 41 element in the position of sudbury?

Elliot (hockley): Well with regards to what you suggest, I really do think that before altering anything you should try and investigate exactly what your neighbours are receiving channel wise, and at what level of reliability, as just because they pointing at Crystal Palace it doesn't by any means mean that they are having good reception, as reception from Crystal Palace on DUK's trade predictor shows a mixture of variable and poor right into 2013. Bluebell Hill by the way showing far worse, with more "poor" reception, or none at all, being indicated right into 2013.
That said though, in situations such as yours even moving a few yards or so to the left or right can make big differences in reception, this likewise applying to aerial heights, as in many circumstances an aerial at gutter level can sometimes out perform an aerial perched on top of a pole mounted on a chimney, and so it shouldn't always be assumed that highest is best, a mistake made by many! but it does require time consuming experimentation to find the best spot.
Another point is, that even although you are about 30 miles or so from Sudbury I feel your reception problems might be caused more by signal obstructions rather than sheer distance, and large multi-element aerials with their "sharp pick up pattern" does not help in this type of situation, and indeed can actually make the situation worse in certain respects, so if its easy to arrange you "might" benefit slightly by using your newer aerial for Sudbury.
It could well be that where you are located pockets of good reception exist for "some" Mux's, so I wouldn't be surprised if some of your neighbours can receive what you cannot, but that's just the nature of RF signals insomuch that nothing can really be guaranteed in these type of areas.
Anyway, I would be interested in knowing the outcome of any investigations carried out on what exactly your neighbours are receiving, especially on the channels you have problems with.

Elliot (hockley): Meant to include, if you are experimenting these are the bearings from you for the transmitters mentioned.
Crystal Palace - 253 degrees
Sudbury - 2 degrees
Bluebell Hill - 206 degrees

jb38 thank you once again for your help its interesting because i thought sudburry was 7 degrees not 2 that maybe why im having a few problems i will readjust as my current 91 element is pointing 7 degrees i will let you know what I find out, tomorrow i will put the new 41 element aerial up onto my mast and see what happens see what i can find on other transmitters

Elliot (hockley): Sudbury is 7 degrees if you are in Hockley, but 2 degrees for Southend-on-Sea, as per your second postcode.

KMJ,Derby: Yes, quite correct KMJ, although in the practical sense the relatively close Rouncefall transmitter being on the same frequency as Sudbury would most probably upset any accuracy involving the exact direction angle for Sudbury anyway.
Elliot (hockley): Based on KMJ jogging my mind on the Hockley location, I carried out a new assessment of reception using a SS5 post code (Hockley Post office, Spa Road) and although it lifts Sudbury's MuxC/ArqA out of its variable classification on June 12th next year, unfortunately on the downside Bluebell Hill to all intents and purposes is virtually wiped out as a possible for reception, indications being far worse than at present.

John Stone, Hawkwell, Hockley, SS5 4JN. Hi, a couple of things; Rouncefall is very strong around this area and me and a lot of other people are having problems with too much signal. We have been used to having to struggle with weak signals from Sudbury, Dover, Bluebell Hill and/or Crystal Palace. We have erected large aerial which we now don't need. My Father inlaw lives in Rochford SS4 , about 2 miles away and has always received signals from Bluebell Hill, he can now receive Rouncefall on the back of his aerial, full strength! I think I will try and swing my aerial round to Bluebell Hill and see what happens. The other thing that someone may be able to answer is why is ITV 1 + 1 and ITV 1 HD from Sudbury/Rouncefall transmitting Meridian TV?
Thanks.
John.

John Stone: As far as your query on ITV1+1 & ITV1HD is concerned, unfortunately I cannot answer that as its really more in Briantists domain as far as an explanation is concerned, although I do see what you have mentioned listed in the PSB2 & PSB3 Mux charts.
However on the technical side, I found your reception report interesting as its gives a further insight as to the variable reception that exists in your area, with the post code indicating as you being only 1 mile away from the Rouncefall transmitter, so you must indeed get blasted with the signal.
I would appreciate though if you could give a further report on what you find when you try your aerial facing Bluebell Hill, as the Digital UK's trade view shows the four Mux's as being variable.
You will most likely have to carry out a manual tune on your set to receive Bluebell Hill, as Rouncefall etc would take up the low EPG positions on an auto-tune pushing Bluebell into the 800 ranges, that is if you can pick it up at all, as the powerful signal from Rouncefall might somewhat desensitize your tuner for other lesser powered channels.
The four Bluebell Hills Mux channels being 59 - 24 - 27 - 39
