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

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

Oh well I tried my Samsung BD-C8200 box at my parents (CB11) and could get no HD from Sandy, their Panasonic TV pulls it in ok. I have emailed Amazon concerning a warranty return. I await their reply in anticipation.

There only about 5 areas for ITV1+1 and ITV HD. So you only get Meridian. I live in Sometset and have make do with Welch on those two.

Gary Dadds: Thanks for the update, which has somewhat proved my suspicions about the box, however this was reinforced when I finally managed to have a look at the user manuals spec for that device, as it doesnt state that its capable of operating on DVB-T2, the UK's freeview HD standard, as its only shown as a DVB-T device, that being the cause of your problem.
