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.

Briantist, have you seen there is a common thread to a number of recent posts regarding loss of signal level from Crystal Palace? In my case I now have only Muxes 1, B, and C, with zero signal levels on the others, having had until recently very good signals on all muxes. Is there a statement somewhere which says that the Crystal Palace signal level has reduced and will only be increased to full power on the final swithchover day? I can see from the publicised signal strengths that this is the case, but a statement from the Transmitter Engineering posts might be useful.

Graham: It is legally forbidden for the output levels of any transmitter to be reduced before switchover. This has never happened.
If you have issues, they will be related to reception, rather than transmission.

Briantist: I am sure what you say is true - but wonder if work in advance of reconfiguration of antenna arrays in ahead of swithover could be having some effect on signal levels for some marginal locations - although ERP is maintained. Whether this happens or not; it should all sort itself out after the final switchover when Freeview gains from a massive increase in transmission power.

An aerial company makes this statement on their website with regard to Crystal Palace Transmitter: "Note, as work takes place on various digital transmitters (to prepare for the DSO) you may experience problems, e.g. with certain MUXES disappearing." So, the output power may not be reduced, but this issue of missing Muxes is recognised by a professional aerial company.

Graham: It's poppycock, the final commissioning testing of Crystal Palace happened ages ago.
Even Digital UK's report says "Crystal Palace main transmitter: ... TV (digital) working normally.
