Kieran R: Sorry, for some reason you had a Southend-on-Sea postcode against your post which I assumed was correct.
If you're using Crystal Palace it's even more likely that the fault is somewhere at your end. Black-and-white and fuzzy/snowy indicates low signal levels or high noise levels. Black-and-white, but clear, suggests a problem with your TV. Check the Colour control!
Digital UK's predictor shows that for you, reception from Crystal Palace will be highly variable now, and up to switchover. While the PSB multiplexes are expected to work reasonably well after switchover, the COM multiplexes probably won't - it shows no prediction, because the same channels are used for the commercial multiplexes from Rowridge.
If you just moved your aerial, rather than changing it, it probably won't work very well. Hannington requires a Group E aerial designed to cover channels 35 to 68, while Crystal Palace requires a Group A aerial designed to cover channels 21 to 38. Wideband and semi-wideband aerials like the Group E type are a compromise, and they're particularly poor at lower frequencies compared to a similar-sized aerial designed for the job.
The analogue signals have to be switched off to make digital TV available to the vast majority of the population, and much more reliable for most of the people who have it now. There just isn't space in the UHF TV band for high power digital at all sites alongside analogue on their current frequencies. The Government also wants to sell off a part of the band for other services.
If you really can't avoid the trees, you will have to consider satellite or cable.

The introduction shows Associated Rediffusion as the ITV company from 1955 to 1968. Technically I believe that Associated Rediffusion operated from 1955 to 1964, then Rediffusion London from 1964 to 1968 (when Associated Newspapers was no longer involved).

Hi,
Ive had a Group A aerial fitted to receive Crystal Palace from Stevenage. Works ok.
Notice that after switchover a new Mux 8 is to appear on Chan 42 outside Group A? Does this mean I should really have installed a wideband aerial? Is this info correct? UK Digital site doesnt show this new channel and states Group A will be Ok now and in future?

Nick:
That information comes from NGW's Interleaved Frequencies analysis of what channels new multiplexes could potentially be launched on to reach the maximum amount of the Crystal Palace coverage area.
I'd be surprised if enough additional TV services were ready to launch by mid-2012 to require a second new multiplex - C29 (NEW7) would be preferred, but even that isn't ready to go at switchover. There's also a strong chance that the channel plan would have to be redone since the plan it was based on wasn't final.
The plans were made on the basis that while C42 is strictly outside Group A, many Group A aerials have usable gain at that frequency. It's not a sharp cut-off at C38. However, looking at some gain curves I think they're being optimistic: Gain (curves), Again (RG47SH)

Kieran R: I really can't offer any other advice. The signal strength is either too low or the level of interference too high - probably both - for services from Crystal Palace to be reliable at the moment. It will vary over time, because the signal strength *does* vary with changes in weather conditions, including as the atmosphere warms in the morning and cools at night. This is taken into account in the predictions - it's why Digital UK give quite a conservative prediction to the general public, and why the trade view is expressed in probabilities.
Your options are to stick it out for about a year until Crystal Palace switches over (but you might not get mux A, C or D), put the aerial on a longer pole to see over the trees, move the aerial to a different point on the building to see around the trees, cut down or prune the trees, or get satellite or cable.

Have lost all channels in MUX A entirely on Freeview this week, postcode WD19 area, Watford. Have two boxes on different aerials. One aerial is in a loft, the other is exterior. Both on Crystal Palace transmitter. Have tried resetting both boxes but channels are still not found. Any ideas?

I have recently moved in to a property in N7 9SE and tried to set up Freeview HD using the built-in FreeviewHD tuner in my Sony KDL-46EX703U.
I autotuned the digital service and 108 Channels were found. All the standard channels are working fine, but when I browse to any HD channels the signal appears for a split second and goes, flickering in and out of view. What appears is a random image of green squares and so on.
The TV is connected to a communal roof arial and the cabling and arial seem sturdy and not obviously broken - as far as I can see.
Can anyone advise whether I am experiencing bad signal or perhaps the wrong arial etc?
