Hi, thought I mention freeview issues again in SL2 2NN area West Slough (nr burnham)
For 5 weeks I have had no ITV, no Ch4, no Ch5, to start with BBC had also fallen to unwatchable levels and remained like this for around 8 to 10 days. BBC is back but the other still 100% missing
Checking every now and then to see if they have stopped messing about....
ch 25 85% signal strength 100% quality
ch 33 85% signal strength 100% quality
ch 21 20% signal strength 0% quality
when will someone actually notice they don't know what they are doing ?

Is it possible to have a HD test card transmitted on a regular time so we can adjust our sets.

I have just purchased a new LED HD ready TV with HD digibox. I can receive all/most chanels except HD. Will my external (roof) ariel receive HD after the switch over or should I investigate a new ariel now? Is Crystal Palace transmitter sending HD signals in all directions at this time? Any help with these questions will be much appeciated. Many thanks. David Kent

David Kent: It's likely that there will be no need for a new aerial.
The transmitters that operate before digital switchover do not carry HD except for Crystal Palace and a few others.
The Crystal Palace pre-switchover HD multiplex has been shoe-horned in. It's coverage area isn't as big as that for the other digital channels which might explain why you can't pick it up now.

David Kent: another thing to keep in mind is that the low powered Crystal Palace HD transmitter is also temporarily on the same frequency as the similarly powered ITV3 multiplex used by Sandy, this causing lots of problems for anyone even remotely North of London, although judging by reports it seems that its C/P's HD service that's taking the brunt of the same frequency clashing problem.
