Nick,Woodbridge.I would strongly look up again single frequency interference concerning your long standing problem with the ArqA multiplex on frequency 60 from Sudbury.My suggestions for you to ponder would be Freesat,Virgin Media (Cable TV),Sky,diplexing your freeview aerial to receive an alternate ArqA from another main transmitter receivable at your location or just make do without an ArqA multiplex from Sudbury whatsoever.
As you rightfully say "Given Up" is precisely what i will do if i was in your shoes,and in my similar situation myself earlier concerning the elusively difficult ArqA and ArqB multiplexes on frequencies 53 and 60 respectively from Belmont in my location that is exacly what i have done,"Given Up" myself !

Michael.You may have a good point there concerning Local TV in your earlier text today at 8.32pm.You never know if Local TV ever does take off it will ultimately go down the road as ITV have done,almost national with only the local news bulletins and local commercial advertising left.
History will repeat itself here !

Kev,Chippenham.That could be a possibility if as you implied your new neighbours using some equipment could suddenly introduce interference.
It is unlikely though that more channels crammed into each mux will weaken the signal quality as such.
One other likely candidate that you mentioned only affectimg the BBCA multiplex on frequency 61 from Mendip the highest frequency used on this transmitter as such is possible aerial erosion.Check your main aerial lead and its main aerial plug as well as the aerial socket(s) of that main aerial itself for any signs of water ingress and rust stains as the highest frequencies suffer more in this situation than the lower frequencies.
If aerial erosion is the culprit then you may need to replace either the main aerial if it is eroding or the eroding main aerial lead and main aerial plug.
Or if it is an internal connection such as an aerial co-ax lead or plug that is at fault,that requires replacing as such !

Andy.Eastbourne,BN22 7EN.I would look up either single frequency interference or the inversion effect as likely culprits.

Im sure there are a lot of Welsh viewers in Wales/Cymru who dont want "foreign" programming from England,relating to England alone and concerning England alone to the decent Welsh population of Wales/Cymru as a whole.
Live and let live !

Maureen.New Milton,BH25 5SZ.Having checked with the BBC Reception Test link provided with your text there are no problems reported as such.
I would strongly look up single frequency interference as a likely culprit !

Paul.Hythe,SO45 6JG.First of all is it the radio or TV signals that is causing you the difficulties as judging by your two previous comments both were posted on the Basingstoke DAB radio transmitter page and this one on Hannington main TV transmitter page.
If it is TV related is your aerial polarised horizontally facing Hannington,or polarised vertically facing Salisbury major relay.Also what is the colour tip or your aerial if you can identify this as such,as if you decide to realign the aerial to Rowridge you will need to either change your aerial as Rowridge main transmitter is an all group A mast (red tipped group A aerials preferably will need to be used here),or consider diplexing your aerial (using a second antenna) with your current one facing either Hannington or Salisbury with a second antenna pointing to Rowridge.

Ken Clay,Warrington.One possible reason for your fluctuating signals on the BBCB (HD) multiplex from Winter Hill on frequency 54 is the siting of your aerial,in the loft under a slate roof.And it is common for BBCB (HD) multiplexes anywhere in the UK to suffer picture pixellations more so than the normal SD multiplexes which are often unaffected as such in normal conditions.
You may have to consider either moving your aerial within the loft to alleviate the difficulties you stated or to relocate the aerial externally onto the roof.
As for manual tuning or scanning this is highly recommended as auto tuning or scanning often picks up weaker transmissions on the lower frequencies while more often occasionally failing to pick up stronger transmissions on the higher frequencies,and believe me Winter Hill currently uses the higher frequencies and these transmissions can be omitted when the weaker Moel-Y-Parc transmisions lower down the frequency bands (middle bands) are often picked up first during automatic tuning/scanning around Warrington,Liverpool and South Manchester conurbations,etc.

Lorry.One indicator is the transmitter engineering text immediately above your text.Crystal Palace main transmitter TV digital liable to interruption.
Yes sometimes the transmitter engineering texts should be more transparent as such in advance of any ongoing works or interruptions so we are well prepared as such.

Julie Wilson.Bingley,BD16 1RB.First of all is your aerial polarised horizontally meaning it receives most likely the main Emley Moor transmissions,or is your aerial vertically polarised receiving either Idle or Keighley transmissions both being major relays.
Look up the transmitter engineering texts on the Emley Moor,Idle and Keighley pages just recently as well as the BBC Reception text by clicking that link on your first text back in November 2011.There is an issue currently at the main Emley Moor transmitter which also effects all its dependent relay masts as such simultaneously.
