Steve Flynn: The poor quality on some muxes is indicative of the signal either being subject to interference from another transmitter (including an RF modulator) or the signal is corrupted due to multiple reflections or partial obstructions such as trees in the signal path. The Digital UK postcode checker does not make a prediction for the Hannington COM muxes at your location and significantly shows the PSB mux on C42 as being less reliable than the other two. This makes me wonder if Heathfield signals could be present at a very low level, but sufficient to cause problems to reception from Hannington. Heathfield shares C41, C42, C44 and C47 with Hannington. If this is the case careful positioning of the aerial to find a null for the Heathfield signals will be required.

Hi, Please could you tell me why there is no ITV3 transmission from the London tansmitter at East Grinstead West Sussex? Also the number channels transmitted is low compared with other transmitters. Thank you.

Tony Putner: ITV3 is carried on the SDN mux which is only transmitted from main transmitters and a number of former relay sites which serve relatively large numbers of viewers. The reason for this is based on economics, as additionally serving all the other relays would double the transmission costs whilst only adding about 8% more viewers. The owners of the COM muxes therefore declined when invited to consider serving additional sites. Crystal Palace is your nearest main station for reception of the full six mux service.

Tony Putner: Because the Commercial networks operate purely for profit and so choose those sites where they can cover the most viewers for least cost:

The only thing you can do is investigate the possibility of receiving from another, full-service, transmitter.

Although in Kent I can only get London from CP on Freeview, whereas a friend 100yds further down London Rd gets London on the Front room freeview and South East on the back room both with her roof arial.
My Community new Digital Dish arial is fitted at equivilant to gutter height on a house but is 1/2 way up the Block height. When it was fitted 2010, apparently if Tenants wanted Sky they could have Sky and pay tuned to this same arial.
I have just noticed on my Orange PAYG Mobile that EE is now showing so in my area already but dont use it.
My Question is should some of the occasional No Signal and pixel bands be due to 4G and have I got worse to come.
At present since Switchover Quality is shown as 100% but Signal has is constantly jumping from 80% and settles to 61% then on channel change goes back upto 80% then back to a usual 61%, or is this Digi. Box about to turn up its toes.

Ann: Your friend could be picking up the signal from the Bluebell Hill transmitter located at roughly half way between Gillingham and Maidstone, it being BBC1 South East for news etc.
Not quite sure what you are meaning by "digital dish" as that is used for Sky or Freesat purposes Freeview being received via a normal aerial, and so the question would be whether or not you are using a normal aerial? or is it a communal one?

Thanks jb38 I thought that may be the reason although I didnt know if Bluebell was still operating.
Yes it is a 2010 fitted Communal dish aerial and total rewiring to each flat and as mentioned in my 2nd paragraph is fitted on the side of Block 1/2 way up which is approx gutter height on a normal house. I know of a couple of Tenants who wanted Sky and the Aerial Contractor could supply and tune to this aerial instead of fixing individual dishes which are not allowed. The blocks would look like millipeds if seperate sky were fitted.

Ann: The frequencies that EE are currently using for 4G are among those already in use for mobile phones. They are not part of the former UHF TV band, which is due to be used for 4G in a few months time and has been the subject of wild speculation and scaremongering. Reception from Crystal Palace is really among the least likely to be affected, and your installation might already be fitted with filters which prevent reception of UHF signals on frequencies higher than those used at Crystal Palace. This could also be a factor in the non appearance of Bluebell Hill on your TV when scanning for channels.

Thanks KMJ I thought EE(Orange) had bought into the New 4G tipical con.
I dont somehow think the Council would think that far ahead, just get the Switchover rewiring job done as cheap as possible and tackle any problems when they hit. I guess it will be a case of wait and see.
Thanks guys for tempory peace of mind, I knew I would get the true picture on here.

Ann: You are correct in that EE was successful in bidding for spectrum in the 800MHz block. Other companies to win spectrum are Hutchison 3G, Telefonica UK and Vodaphone. Services are expected to launch using these frequencies around the middle of this year - 2013.
