The symbol shows the location of the Crystal Palace (Greater London, England) transmitter which serves 4,490,000 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 Crystal Palace (Greater London, England) mast?

I have purchased a new Samsung HD BluRay/PVR and cannot receive any freeview channels on it despite having no problems receiving them on my 5year old Panasonic Freeview TV.
Having read some of the other comments it does appear that older sets may have a better sensitivity and that as I am probably due a new aerial it would be the way to go.
I currently receive my signal from Crystal Palace & would appreciate your advice on what type I need to buy (ie Log Periodic or Wideband) & size.
Many Thanks

Chris Low: For now I'd go with an 18-element Group A Yagi. The prediction suggests - because it's below 100% with DUK's assumptions - that a log-periodic probably wouldn't have enough gain.
You do not need a wideband for Crystal Palace either now or after switchover, it is unlikely that any new services would start up after switchover that are outside this group. Widebands have to be larger to provide the same amount of gain as a grouped aerial, particularly in Group A.

Chris Low: If you can receive Freeview perfectly OK on the Panasonic but not on the new Samsung (on the same aerial) then a simple booster is all that should be necessary to correct this, as changing your aerial would be like taking a sledge hammer to crack a nut, to use the expression!
Have a look on e-bay under "TV amplifiers" or "boosters", something shown as about 10db gain would suffice so long as its shown as having two outlets, one lead to each device.
(Maybe you could indicate the model number of your new purchase)

Chris Low: You should also be aware that Mux 1/2 (BBC & ITV) presently indicate as being variable in reception at your location, and with this continuing until April 18th next year, so even although taking the predictors element of inaccuracy into account good reception isn't guaranteed on these two multiplex channels no matter what you might do.
That said though, the booster I mentioned should certainly get over the problem you mentioned "if" its caused by a signal just under its receiving threshold, although I am a bit suspicious of you not getting anything and that's why I requested its model number.
Just for a matter of interest, boosters are generally always better as near to the aerial as you can get them "if" excessively long downleads are involved, (loft mounting perfectly OK though) although based on what you report anywhere in the vicinity of the TV or PVR being used should be OK if a weak signal is the reason for your problem, and not caused by a fault in your new purchase.

About 16 months ago purchased a Sony DVD recorder. About 3 years ago had new aerial installed on my chimmney stack. Annalogue reception good, digital reception thru DVD recorder has become appalling,impossible to see picture accompanied by loud screeches. Sony (via DVD supplier) state not their problem, Supplier wont change DVD recorder to one that will work with poor signal.Now "up a gum tree" what do i do?

Hi
I have had a Panasonic HDTV recorder that up until 10 days ago received HDTV ok (albeit with a low signal). I have now lost all HDTV. Is there a problem/work with Crystal Palace. I live in Leatherhead and know that it is a bit "iffy" here.

graham campbell: Well what both Sony and the DVD supplier have said is quite correct, as they aren't responsible for you receiving a poor signal, this aspect of reception possibilities unable to be checked on as you havent mentioned where you are located (pref:post code) nor anything about your aerial being used, such as loft or roof mounted, or maybe even on a communal system.

graham campbell: Apologies, just noticed that you did state that your aerial was on the chimney, if you indicate your location the signal expected at your location can then be checked on.

Andy Hagerty: As it says above, there are no problems with the transmitter. I would have a look at Freeview reception has changed? | ukfree.tv - independent free digital TV advice .

HP15 6NN. High Wycombe. Please can you email me an explanation? (As I am nearly 80 I cannot understand complicated instructions.) I had a new digibox installed on Wednesday, using the very helpful & efficient BBC Switchover Help Scheme. The engineer said I had a poor signal from my aerial (best available 10 years ago & I have had no previous problems.) He put up a new aerial facing exactly the same direction as my old one (however not the same as all my neighbours.) He could not remove the old aerial as his ladder was not long enough. I have 2 sets & now use my bedroom TV mostly. After he left I was unable to get the digibox to work. My other TV (app. 18 months old) was still OK. But after teething problems, & re-tuning it via the Help number, it worked spasmodically, but I could not get all channels all the time.
Today is a different story - my bedroom TV has "no signal" & broken-up picture with bad static & will not change channels. The sitting-room TV is now also affected in the same way, but at 5pm I can get some freeview channels.
(Apologies for this long explanation.) Is there a problem at Crystal Palace? Do I just have to accept that from now on, I am unlikely to get a proper service until next April? If the Switchover Engineer returns to try to sort me out, I have to accept what I am told (i.e. I live in the wrong area!) If there are no problems at your end, do you think it is the aerial being sited incorrectly? Thank you very much, in anticipation of a reply. Claire Evans
