fin: Could the Sony Bravia TV be referring to TV channels (not radio and others) only whereas the recorder shows all?
I would be more concerned with ensuring that all channels are present. Confirm that you have BBC One, ITV1, ITV3, Pick TV and Yesterday and these are one service from each group or multiplex. If you have all of these then you have all multiplexes and therefore all services carried by those multiplexes.

Mike: A HD TV does not necessarily have the ability to receive HD signals. These are usually described as HD Ready. Full HD simply means 1080p and doesn't mean that a Freeview HD tuner is contained within.
Look in the specifications. DVB-T is the standard definition format and DVB-T2 is the high definition one. So if it says the only the former, then it won't receive HD pictures itself.

Sean Marshall: The signal strength is not the main factor with digital reception; it is quality. So long as the strength is great enough to produce give "good" reliable quality, then I suggest that you do nothing with your aerial if you will have to pay someone to make any changes.
Directional aerials by their nature are more sensitive in one direction and less so in others. So if the interfering signal is coming from a direction at which your aerial is least sensitive then it will produce less interference to your receiver than had it been from a direction where your aerial is more sensitive.
So don't read the Tradeview predictor as being what you will actually get. It is simply a guide.
If your aerial happens to be in a spot where it picks up no signal from Crystal Palace then it will endure less interference than had it been in a location where it got a little. Such a difference could be metres.
Clearly the only way to give a definitive answer is to measure the signal levels on-site. On the basis that this will cost and that you already have an aerial, I suggest, just as the response from Digital UK says, that you leave it and see.
Should you find that you have an issue, then you are now briefed on the possible cause and possible solution.

Mike: I found the manual here:
http://pdf.crse.com/manua….pdf
The specs on page 48 only say "DVB-T" and not T2.
This review mentions it coming out in 2008:
Sony KDL-40W5500 review from the experts at whathifi.com
DVB-T2 was only finalised in 2008, so when the model was conceived, the specification for HD broadcasts had not.

Tony Browne: Where are you? To the west there is Stockland Hill which uses the same channels and in the east there is Crystal Palace which does. There are probably others that might interfere in places.
In some locations adjusting the aerial from horizontal may be helpful for reception of the three Commercial channels you refer to.

mh: What's the make and model of your TV? The description you give suggests that it may be that it won't receive post-switchover signals.

mh: That model is on Digital UK's "2k-only" list of equipment so will not receive post-switchover signals:

2k mode was used for signals before switchover and they are in 8k mode after switchover. Hence on 4th April BBC standard definition services switched to 8k mode which is why your TV wouldn't tune to them.

JohnM: There are less ITV1+1 regions due to the cost of creating +1 feeds for all ITV1 regions. For the same reason there are limited ITV1 HD regions and similarly the BBC does not provide regional BBC One HD feeds.
If missing local ITV1 programmes is that much of an issue, then set them on your PVR and you can watch them back at any time. I didn't realise that there was that much local programming left on ITV1....for cost reasons.

Phil K: Stockland Hill's COMs are co-channel with those of Rowridge. Last night they had a power increase so you could be getting interference from them. You may have to switch your aerial to vertical to reduce the chance of such interference as well as picking up stronger COM signals from Rowridge.
