Which companies have run the Channel 3 services in the Mendip transmitter area
Thanks for reply I only have one aerial a wideband pointing at Mendip so seems its picking up unwanted signals from back of aerial. Not bothered about region just want pvr to stop dropping PSB at will, picking up Rowridge & poole with poor quality pictures & digital break up.

Variable attenuator makes no difference, just lowers signal strength and bad signals just get worse, not better! Now today cannot get the 'bad' channels at all - receivers just say No Signal. It is raining so I guess that effects signal, BBC chas all OK as usual. Dont know where to go from here. Should I try pointing ariel towards Wenvoe and try that?

No BBC at all still, and the other channels are messed up (except the Humax receiver, which is fine). I've almost given up hope, next step is to enquire with a local TV repair company and see if they have any tips.
Good luck Lordgeous!

Ben Ward: Judging by your latest reports I have to say that I very much doubt if you will ever manage to obtain good reception, as erratic intermittent reception of the type you are plagued with is nearly always because of the signal path between two points being obstructed by vegetational reasons such as trees etc, this also giving a seasonal aspect to the intermittency of the signal plus adding daily changes dependant on whether its wet or windy, something which unfortunately there is no real way around although the situation can in some instances be improved by NOT using high gain narrow pick up angle aerials.
However, looking back again over your various postings I realise that you have already tried a few tests / answered questions from various advisers including one from myself, but the thing that really stands out is the fact of you reporting that the Humax always seemingly operates OK when nothing else does that really intrigues me, albeit of course being fully aware that Humax tuners are one of the best around for stability hence providing reasonably consistent level of signal indication accuracy across the various models.
I would therefore be interested to know the outcome of another test involving only your upstairs set up, namely the Humax and the Panasonic TV, the latter being another piece of equipment that's excellent for carrying out signal tests on because of its versatile tuning menu.
What I would like you to try is to select BBC (Ch61) on the Humax and check the signal strength / quality being indicated, making a note of whatever it is, then transfer the aerial directly into the Panasonic and delete everything stored in its memory by going into the tuning menu and selecting "auto-set up", ignore the warning message and press "start auto setup", BUT! as soon as it starts and you see the empty page where any channels found would be listed press the "exit" button on the remote control as everything will then have been deleted by then, the usual "no channels" message being seen to come on.
That done, go into the tuning menu again and select "manual tuning / access" where on pressing you will see a bar at the very top of the screen with a channel number being indicated on the right hand side of it, then using the "up / down" facility on the remote controls large round button inch the channel numbers either way until you get to Ch61, because as soon as its been selected the signal strength / quality of that channel should be seen on the level bars. (no need to scan!)
If you do not see any level being shown, then insert the attenuator in-line with the aerial socket of the Panasonic and turn the adjuster to fully advanced, nothing will likely be seen at this setting so "slowly" start to bring it back towards zero whilst observing the screen when hopefully the level indications will suddenly jump on, and if they do then adjust it to give about 80% or so strength and then press "search" and let the TV scan for BBC channels, giving an update on results.
Do not by-pass the procedure in anyway, as it has to be carried out in that fashion.

Lordgeous: With regards to the variable attenuator not having improved the situation any, this result was not entirely unexpected when you had reported that a set top aerial only received a very weak signal, and the reason why I always request that a person tries that test first, as its only in situations where someone reports getting a reasonably good signal from a set top aerial test that I would then advise them to purchase an attenuator.
However, I carried out a more detailed check on the signal path route between Mendip and your location, and "if" the post code provided is truly representative of your position then your aerial would be pointing not too far off straight along Camden Road and into a row of houses situated at a slightly higher level, that is as well as them being topped from behind with a higher level line of trees, but to compound this problem even further random patches of trees were seen at various points along the signal path, and so erratic reception has to be expected in that type of situation as its nearly impossible to avoid.
I also carried out a terrain check indication, something I do not take as being remotely accurate as it does "not" show anything other than an obstruction of a hill nature, meaning that a person could be located behind a tower block or alternatively tucked in at the back of Sherwood Forrest and yet it would still show a clear path, however it "does" indicate that the signal from Mendip clips the top of a hill about 2.5 Km or so away from you, the problem there being that if your signal is partially obstructed before it even reaches the more localised and visual tree lined hill / houses on hill problem, then reception is bound to be hit and miss.
I realise that you have said that reception had been OK since switch over, but as your signal path routes over areas with numerous trees (just like applies in Ben Wards situation) then seasonal vegetational growth has to be playing a significant part in your problem, this always being worse when obstructions of that nature are located not that terribly far away, as even a single tree can seriously affect a persons reception let alone a numerous amount of them, and especially so during wet weather.
