PSB1 and PSB2 fell off air c. 14:45, about 25 minutes ago, and LM is not even broadcasting them as a blank carrier. Whatever frequency they broadcast at is just static. My Philips box is complaining "No signal. Please check antenna/cable", and same fault off all devices off both antennas here.

Digital TV an improvement on analogue?

Don't make me laugh.

If you are in an outlying area, which clearly Wales is considered to be, then what you get served up is a second class service for second class citizens.

Engineering works my arse.

The blank screens provided by Long Mountain since 2.48 today is only marginally worse than the paucity of choice they 'offer' when the damn thing is supposed to be working.

A plague on all their houses, and on all those in government who decided this was the way forward.

Forward?

Back on air c. 20:30. Arqiva confirmed it was caused by a HV cable failure to the site. Why the backup generators didn't function, I've no idea. FM radio lasted until c. 16:30 before all that went off air also.

I had to resort to using www.tvcatchup.com to watch the first half of the rugby tonight. Not good. I may as well not have bothered anyway...

john bayliss: It has nothing AT ALL to do with being digital, the transmitter had a serious fault. It would have been exactly the same with analogue.

Briantist, it has everything to do with being digital, instead of analogue. I could have tuned in to an analogue signal from elsewhere; but the digital signal is not strong enough to enable me to do that.

We were presented with a fait accompli, HAD to buy digital equipment at OUR EXPENSE: all for a system that does not provide us with the choice that is available elsewhere, when it is actually working.

That, pal, is why it has everything to do with digital.
