I am starting to think this digital switch over is just a huge con. Before the "power boost" we got 103 radio and TV channels. Now it's 74. Film 4 has gone as has More 4. The box upstairs is displaying artefacts every 30 seconds. The aerial is on a mast on the roof and is almost new and the cabling all good. We have a 4 way splitter box. Now I read something about Sandy Heath not really going full strength until September. Why?! Didn't they have long enough in the first place? I also have been told that the booster in the loft could be an issue but without it how do we split the signal? The Humax box downstairs is giving 74% for signal strength and 100% for quality. Blimey, things were a lot easier in 405 days!!

Adam - I don't follow your post.
What can YOU get and what can YOU not get?
I for one have no idea where Dunstable is.
If you plug your full postcode in top right there are useful links.

Adam: UHF reception can vary greatly between locations only a small distance apart, so we really need a full postcode to see the situation for you.
Taking a postcode for the centre of Dunstable (Bing Maps gives a co-ordinate of 51.8858052045107,-0.52066370844841 which nearby.org.uk translates to LU6 3SH), I get a prediction of 100% on the PSB multiplexes, 73% on Mux A, 76% on Mux C and 92% on Arqiva B. This is the estimated probability of finding a location for a rooftop aerial that would give reliable reception, at that postcode. The simplified coverage checker for consumers will show that as 'good' on all six multiplexes (the threshold is 70%).
I would start by bypassing the booster and splitter and seeing what the situation is like on each TV connected individually to the aerial. If you can get all the channels, plug the splitter in without the booster and try again. If you find that you can't get all channels with the booster, but can without, leave it disconnected. Otherwise, check that the booster has just enough gain to offset the loss through the splitter. A 4-way splitter typically drops 8 dB.
It may all just fix itself as the switchover programme completes. The retune in August changes the prediction for Mux A to 97%, while that in mid-September puts Mux C to 93% and Arqiva B to 99%. The November retune and mode change turns Mux C into Arqiva A, for which the new prediction is 99%.

Nigel.
I too have a 37"Panasonic TV with freeview and freesat tuners built-in. I get, from Sandy Heath, 100% signal on all multiplexes and 100% quality on five of them the HD multiplex shows about 20% quality. There has been no pixelating on any picture and there has not been since April 2011.
I also use a Humax HD recorder,the signal quality on all including the HD multiplex is 100%, signal strength between 90% on the PSB channels and about 78% on the comm. multiplexes.
That is using the same source signal, cable etc. so I wonder if the Panasonic TV is not displaying the quality properly on Ch 21? The same could be happening to yours?

The aerial is outside on 16ft pole. My tv is HD ready and I have an LG full HD dv3 recorder but no HD transmission. What else do I need?

You need a recorder or TV which has a "Freeview HD" tuner. See:

Robert Dawson: 'DV3' is probably the stylised DVB logo from DVB - Digital Video Broadcasting - Home . The model number is likely to be on a sticker on the back of the unit.
