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?

FJC Farrar: No, there is no effect as the current are being provided by the same panels that have been there for the last decade.

The new equipment is being used for the current and will just switch to digital, as it did on the recent commissioning tests, overnight.

Thea: As your query concerns a problem the you really have to indicate your location (pref: post code) to enable an assessment to be made on the signal level expected in your area.

However as far as one device being able to receive OK whereas the other doesn't is something quite commonly experienced by many, and with the usual reason for this being that because no two tuners have the same sensitivity its always the more sensitive types that's able to produce a on a weak signal whereas the less sensitive types cannot.

There is of course a complete reverse of this situation where excessively strong signals are involved, this being another reason for requesting your location.

Another factor to keep in mind is that there is constant work taking place at in preparation for the in April, so glitches and breaks in reception has to be expected at any time.

Hi. Postcode HP10 8ES. Have an with 8 crossbars, installed 6 years ago on pole attached to outside of chimney. Feeds into in and to 4 sets around the house.
Worked ok on until a couple of weeks ago when we started losing sky news, dave and a few other - all late at night. Unable to receive HD channels at all.
Tried retuning - no difference.
2 nights ago lost them again and they have stayed lost, even during the day!
Suggestions please.....(do I need a high aerial?)
Thanks
