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?

Christine Clarke: hi. My tv is an August 10 inch with built in free view. Its also hd. I've got a superb picture at home running it on batteries and any one of the 3 ariels supplied. Want to use it in Wimbledon Park so tried retuning it when there last year. I live in west Sussex so we're on Midhurst here. HELP.

Christine Clarke: Thanks for the update, however with reference to the content of, when you tried retuning the TV at Wimbledon Park last year "if" this was carried out using the aerial supplied with the set then reception cannot always be guaranteed using this type of aerial even although it might well have been satisfactory at home, as reception is not only dependant on terrain conditions (trees / high buildings etc) associated with where you are located within the Wimbledon Park area but also the screening effect of the walls in the building you are tuning the set in.
Judging by what you have said, if the W / Park location does not have an external (or loft) aerial installed then your best policy is to try and retune your TV whilst its temporarily connected into one in the same area as yourself, this being purely for the purpose of storing the channels into the set thereby making it considerably easier to experiment with the positioning of the aerial supplied with same by knowing that the TV is pre-tuned.

Christine Clarke : Just a thought! but that said was based on the assumption that the query involving reception at Wimbledon Park was "not" being made purely on your experience when trying to use the TV outdoors on a day trip or whatever? because if it was, then the only way of possibly rectifying the situation is by moving around, this being where pre-tuning the TV would be a decided advantage.

Phil: If you are referring to a Freeview TV and which has already been disconnected from the mains (or completely switched off) and the situation has remained the same, then carry out a "factory reset" on it followed by an auto-tune, this procedure also known as "default setting" or some similar sounding term.
If though you are using a Freeview box coupled into a TV, then check that the lead coupling both devices together is still firmly seated into their respective sockets, if they are, then carry out that said in the first paragraph but on the box.

Dear Sir
My Recorder stated on the TV screen, that there was a new channel (or programme?). I updated the Chanel List.
I no longer have BBC4HD and other HD programmes on this channel, Channel 33.
I see on the Television, which uses the same aerial, that the Channel 33 signal strength is much lower than other Channels.
Is the Channel 33 transmitter not at full strength at the moment?, and if so when will it be corrected?
I had not noticed previously which Channel, BBC4HD had been on, and have been recording the programmes for some time.
Have these recently moved to Channel 33?

John Dann: You should try carrying out a "manual" scan on Mux C33, as sometimes than will capture a weaker signal that the auto-tuning process is inclined to bypass.
On the subject of Mux C33 on the COM7 transmitter, BBC4 HD has always been on this Mux channel along with BBC News HD, Al Jazerra etc, etc, COM7 only radiating on 15.6Kw whereas the other Muxes are on 200Kw which could account for the lower signal strength being received, although this increaes to just over 43Kw on September 3rd.
