The symbol shows the location of the Hannington (Hampshire, England) transmitter which serves 470,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Hannington (Hampshire, England) mast?

Problems in the last few days may just be due to the weather (slow moving high pressure) carrying distant co-channel signals into our area.
It is rather disappointing to have problems with so many channels (the worst for years) so soon after changes (DSO) that were supposed to improve things.

Brian G.Yes it is atmospherics/inversion that is the cause as while im typing this i am receiving fuzzy analogue signals from Crystal Palace,Heathfield and Dover transmitters up here in Halifax near to the Yorkshire/Lancashire border !

Thank you jb38, your advice is much appreciated. I guess I will have to get someone out to turn the aerial to suit Rowridge instead. But I have to say I am a bit loath to do that, because I remember the tile damage done by the guys who put that aerial up about 5 years ago. The cost isn't just for the job, there's the other couple of hundred quid to mend the tiles they break clambering up the roof.
I don't think I have much option though, because all the channels are now starting to break up intermittently, which will only get worse as leaves come out fully. At least last year, during the summer, the BBC channels survived (and a couple of others some of the time) and there were the analogue channels. This year indications are that there won't be anything left at all. But what I just don't appreciate is how ridiculous it is that nowhere is there official acknowledgement that there are these problems. When I have phoned up to try to get advice, that any rain and leaves on trees are a factor is just completely denied. And not even just denied, the very very suggestion was derided, as I was an idiot. It was disgraceful! And there was no suggestion made then re changing to a different transmitter. The "problem" was just dealt with by deriding the problem.
What I don't understand, also, is why the aerial people that I had out to see if it could be improved, didn't tell me that I should be changing to Rowridge!
And re Rowridge I looked to see what manual tuning to Rowridge used frequencies produced. And there is absolutely nothing. There's no trace of recognition of any signal at all. I know the aerial is pointing the wrong way, and that it will (should) improve after the 21st, but I would have thought there still ought to be something getting through. But I haven't got a choice, I will have to try.
Thank you very much again for the advice....J

Joan: Well its totally inexcusable for any aerial installer to damage roof tiles and not have them replaced at their expense, as they should have insurance that covers this sort of thing. However as far as leaves on trees is concerned and especially if wet, this is something that's common knowledge by anyone involved with the technicalities of reception, as they have a blocking effect on signals whether its analogue or digital, although it always appears worse on digital reception because of it being so critical.
As far as trying tests to see if you can pick up Rowridge on the rear of your aerial is concerned, only try tests using manual tuning on Mux Ch24 as its only the BBC mux that's on 200Kw at present and nothing else.
Although being unaware of the brand / model of TV or box you are using, but when on the manual tuning menu on many devices and you enter the channel you want to scan into the choice box, as soon as you do this the signal level being received on that channel immediately comes on, this meaning that if you are only testing the channel you dont actually require to carry out the scan.
I do appreciate that as you have mentioned yourself you are on the extremities of both Hannington and Rowridge, but the vertical polarity output is officially predicted as being superior for reception, although horizontal should also be possible but just at a slightly lesser strength, but try another scan on Mux Ch24 and see what (if anything) comes up.
A qualification on this though as far as the present is concerned, numerous people have been (and still are) experiencing poor reception across large areas in the UK from the North downwards because of the prevailing current wave of high pressure, and with this causing interference to reception by the fact of enabling distant stations to be received which are in many cases clashing with the local ones, so any tests you carry out are unlikely to have much success until this problem settles down again.

Keith Sheppard, Dave and Brian G. etc,
Same here in Hook. Hannington service significantly degraded since DSO inc PSB multiplexes. Exhausted all options except Ae change. Just waiting now for April DSO and hoping to Rx stable BBC South from then on.

Further update. Contacted Digital UK and they say that Channel 44 is not now broadcasting in my area (Yateley,Hampshire)and that Channel 47 has variable output. They can only suggest waiting until April updates. They give no reason why the service had declined so badly. Worse now than before switchover. Also strange that Hannington continues to say 'No reported problems' even though we know and Digital UK confirms, that there are big problems.

Further update from Digital UK: Chanels 41 and 44 no longer working in many areas served by Hannington as they are now being used by Crystal Palace until 4th April. Also Channel 47 on very low power until April 4th. So, many people served by Hannington have been suffering in order to maintain analogue services to Crystal Palace until their 4th April swichover. Cannot find out who made this decision but bottom line is that those affected on Hannington will have to wait until April 4th to get good reception again on Channels 41,44 and 47.

Dave: Rubbish, Crystal Palace is not, cannot, and never will use C44 or C47.
The restricted aerial is there to protect analogue services at the Guildford relay (a relay *of* Crystal Palace, true), and that restriction has been in place since 1998. All that's happened is that, since switchover, the PSBs are no longer subject to the restriction. The further round to due east of Hannington you are, the greater the difference between PSB and COM power levels there is. Some boxes cannot handle large differences between power levels, particularly on adjacent frequencies.
The most likely impact is that the COM services will be *less reliable* than the PSBs - it doesn't necessarily imply that you'll lose them completely, but it means that you're more likely to lose them or suffer break-up in adverse weather conditions.
The commercial multiplex operators *have* been permitted to switch to a less robust mode without a sufficient corresponding power increase, which does mean that some people outside the 'Guildford notch' will have a less reliable service than before switchover. I haven't yet asked Ofcom why this has been permitted.

Thanks Mike. I only reported what Digital UK told me so it sounds like they do not know what they are talking about !!!
Their website and the person that called me from Digital UK both say that we will get full service, meaning all the channels we have been used to, and good reception on all of them from April 4th onwards. Let's hope they are right about that peice of information !!!

Completely lost signals tonight for reasons undetermined.
Anyone else lost signals since last night?
