Anita: That will explain why you managed to obtain a good picture when tuned to that station even although its commercial channels are being indicated as being variable as far as reliability of reception is concerned.

But though you should try a test over a week or so with your equipment manually tuned to the Bluebell Hill transmitter and see how it goes, albeit I would be surprised if you did not experience any spells of picture glitching etc due to the fact of the signal from Bluebell Hill being received via diffraction, this being signal bending.

Bluebell Hills mux channels being /

46 (BBC) - 43 (ITV1) - 40 (HD) - 45 (ITV3 etc) - 39 (Pick TV etc) - 54 (Film 4 etc)

Remember to switch off auto-channel update on the various devices you use or you will land up with some channels from Crystal Palace being stored again.

jb38: Guess I with have to become more accustomed to "manual tuning" here. I don't mind the odd glitch had a few of those in Newham on the plus side defiantly No manual tune was required.

Thanks for your time and help

I'm curious why does a freeview hd box require my postcode during setup??

Many Freeview boxes use your post code to determine which of the available local news services it sets as being your main programmes and which are to be 'secondary' (in the 800's). Example, if you live south of Oxford you might well want the South Midlands news as your main feed instead of the South services (sourced from Southampton studios!).

Anita: Yes! as the manually tuning in of a stations multiplexes is a procedure that's essential to master in areas such as your own where reception is possible from more than one station, as its the only positive way of being able to store what's actually required rather than a programme guide loaded with duplicate channels from stations that offer "iffy" levels of reception.

The problem though with manual being that there are a number of devices in circulation that do not offer this manual facility, the designers of these devices being rather blind as to the circumstances that their boxes are liable to be used in, whereas on the other hand there are owners of boxes that do offer an excellent manual tuning facility but they themselves have great difficulty in mastering it, yourself in my opinion, based on that said in your replies, "not" coming into this category.

I realise that MikeP has answered your query with regards to a post code being required, but though I personally do not necessarily approve of a post code system for Freeview boxes as this can cause problems for many people that reside on the doorstep of another region and prefer to view the news etc from that region, myself having a preference for the more usual "choice of area" box that pops up after having completed an auto-tune (not on all boxes though!) by the fact of "area choice" being up to a point self explanatory for viewers of a less able disposition.

Rob: Hi Jb38 sorry for long delay... had a nasty accident was in hospital.. anyway just to confirm the I do get BBC Oxford news and ITV meridian news from Oxford..However i get BBC south and ITV from Hannington but not that great as it comes in the back of my tv aerial that's pointing to Oxford.. its a triple stacked array type aerial i got from screwfix for 19.99... it works well with 26db mast head amp and power box. works well for 3 years so far......Bear in mind i am at the bottom of the village and i have a massive hill at the back of my house where hannington is coming in.. which is impossible to get a decent signal unless i get a aerial tower of 60 foot up lol. I wanted to combine London as i am deaf... the subtitles would often drop out either bbc or itv i can change region then get subtitles back... it was the same problem when we had the old anolougue tv via 888 on teletext.

Rob: Sorry to hear about your misfortune and hope that you are on the mend!, me having put the gap in continuity down to you possibly trying some experiments prior to giving an update on the situation.

However on reading all you have said as far as your reception is concerned and from where, and when taking this into consideration along with the fact that the reception you do manage to achieve from these stations is only via diffraction (signal bending) plus an element of reflection, both of usually bringing the summer and winter effect into the equation, I now feel that rather than use any multi element high gain aerial (high gain only under correct conditions) I would be far more inclined to remove the triple element aerial and try either a reasonably flat response DM log, or if Crystal Palace is also being catered for then a Log 40 would be best.

The reason for the change being, that in my experience logs used in conjunction with a high gain amplifier generally give excellent results over any other type of aerial when used in difficult reception areas, this basically due to the fact of them not being quite so sensitive to slight variations in the reception angle of the signal being received and something that is always experienced in situations such as yours, and the reason why that if an aerial is installed in one season and then alignment checked in another its nearly always found that it requires slight trimming to the left or right to return it to perfect alignment, albeit that the perfect alignment is short lived!

Of course most are totally unaware that this effect exists!, but its something that can even be experienced in some areas when a transmitter switches to high powered operation and which can have a knock on effect as far as the reflective element of the signal being received is concerned, a few in my own area having found that their aerials had to be turned nearly 10 degrees to the right when Waltham had switched to high powered operation to regain peak reception.

The only problem I have ever found with logs being the a psychological one, insomuch that many equate large pieces of metalwork as somehow being superior for reception, that is until it gets down to viewing the result of what they consider as being a "dinky toy" aerial, or that they are over influenced by reading aerial gain specifications, all of obtained when the aerial is being tested under perfect short distance line-of-sight conditions, these never the same as in real life situations.

Hi

I live at GU14 6PW and have always received Freeview from Crystal Palace via my loft aerial with booster. Recently, I have lost the channels from the frequency C22 and C23 (hence all the BBC channels) although the other 3 (or 4 on the HD TV) are fine. I have tried bypassing the booster and have the same problem. Why would some channels be affected and not others? Could it be linked to some 4G interference?

I appreciate that loft aerials are not the best option, but as I use Sky for 95% of my viewing, I am not keen to pay for an aerial upgrade.

Amy advice or thoughts will be gratefully received.

Thank you.

Kevin what aerial do you is it new one or old one...If the aerial is old one... check the cables if possible replace them with double screened cable and make sure the aerial is correctly lined up..an small movement can mess up the the signal. so try move it a little at a time till the signal is 80%.. i find if its 100% it be too much gain....will cause problems.I do think for London it should be a Group A areial the reason for that its group A's have a really good gain and picks up Crystal palace... If the booster is very old... try replacing it... i had one of mine burnt it self out. Hope my tips helps.

Thanks Rob. I have an aerial that I bought from B&Q for about £20 8 or so years ago. It is wideband, rather than group A.
Last night, I moved the aerial completely and pointed it at the Hanington transmitter. This seems to have done the trick, although I haven't carried out enough testing or getting the positioning perfect to ensure it is as good as it can be. I did however notice the Freeview HD channels were fairly week. When you say aim for 80%, I assume you are referring to signal strength rather than quality. Presumably I do this via the variable gain on the splitter.
The booster is probably about 15 years old - it is one of the bean shaped One For All boosters in blackwith 4 outputs and variable gain. I only use one output, would I benefit from getting a single output booster?

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
