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?

Alex: The HD channels are on lower power than the other multiplexes at present, and the multiplex also uses the same channel as one of the SD multiplexes from Reigate, at the moment.
This will change on 18 April: the HD services will move, taking over Channel 4 analogue's frequency, and be boosted to the same high power as the other multiplexes' new power levels - 20x the current power level.
Night-time does tend to cause interfering signals to travel further, something called 'tropospheric enhancement'.

Alex. The HD channel is also at a higher bit rate, which means that it needs a better signal to noise ratio. This means that it is at a disadvantage of more than the factor of 2 implied by the relative transmit power, when compared with ITV multiplexes and even more when compared with BBC ones. It will still be at a disadvantage when it goes to full power in April.

I live in dartford and a a day or two ago I've lost bbc 1+ 2 bbc news bbc 3.

David, Alex: That is not true. The DVB-T2 standard is just that much more efficient than DVB-T (reflecting nearly 15 years more development). The mode selected for the BBC B multiplex is only very slightly less robust than the post-switchover mode for the other multiplexes, which is about the same as for Mux 2 and Mux A now. The difference in radiation pattern between two channels is typically larger than the difference in the margin required between a DVB-T and DVB-T2 multiplex.
Now that the commercial multiplexes are going to use 64QAM 3/4 mode, not 64QAM 2/3 as BBC A and D3&4 will, the HD multiplex should definitely be more robust than them.

My nephew bought a digital tv (December) with no inbuilt freeview-as he is a teenager can someone please help him with firstly which reasonably priced box he would need and any other information that might help
Thank's

maureen: I find it quite amazing that he managed to buy a analogue only TV unless from some second hand source, is he absolutely positive that it is purely an analogue set and that DVB isn't seen mentioned on the remote control?
However, any of these low priced Freeview boxes seen in places like Argos etc should be perfectly suffice for his needs provided the TV he purchased does have a scart socket?
if not then any Freeview box purchased has to be of the type with an RF modulator so that the signal can be fed into the TV's aerial socket.
Of course needless to say he will require a suitable aerial, although advice on this only being possible by having knowledge of his post code, this to enable checking of the signal level expected at his location.

Thanks Brian but I don't have a set top box, the arial goes straight into the TV.

Adrian: You are indicated as being only 4 miles away from Crystal Palace and as such very prone to suffer from severe signal overloading problems, and indeed likely be unable to get any reception at all come April 18th when Crystal Palace goes over to high power operation, as the signal will grossly overload the tuner in your TV.
If you have a set top aerial lying around try a test using that to see what happens on your Freeview channels, if it helps the situation then you will require to use an attenuator in line with the aerial socket on your TV.
However maybe you could give an update regarding your aerial, that is where installed.

My digital TV often switches the radio stations from 700 numbers to 800 numbers. I retune but it happens again. Other BBC channels are also affected, not the main ones, but The news channel, Sky News and the Red button is now an 800 number. My transmitter is Crystal palace and the TV is a Marks and Spencer brand.
Thank you.

My post code CM9 4SF. My (low gain) aerial is mounted on a pole on the chimney and points at Sudbury. Looks like a 12 element (?) but I didn't put it up there. See aerial photo Pictures by 1stevebevan2 - Photobucket
I can only get PSB's. Is it likely that with replacement high gain aerial I could get COM 5,6 now or no chance, just have to wait until Sudbury goes to full power on COM 5,6 late July? Alternatively with high gain aerial, could I get all Crystal Palace muxes when it goes full power 18th April? Want to dump Sky as soon as possible! (CM94SF)
