Friday's failure had nothing to do to with the method of transmission, but I don't recall such a long outage. I thought it was meant to be covered by backup generators? But this is a separate issue to the one of its unreliability post-DSO.

A conspiracy, Briantist?

I don't believe Lee Harvey Oswald shot the transmitter.

But it is unequivocally the case that the government decided that digital TV was the (only) way forward; and it is also certainly the case that if I wanted to watch TV, post switchover, then I HAD to buy digital equipment.

If there is any part of that you think is inaccurate, do feel free to rip it to shreds.

john bayliss: Well, there is the tiny matter that the digital coverage areas match exactly the analogue ones.

If you had an analogue alternative, you now have an identical digital one.

Richard Jones: The main transmitters have full power backup systems, but on the relay transmitters, no additional power backup systems have been installed. If there wasn't a generator for analogue, there won't be one now.

Long Mountain's a main transmitter, not a relay.

Richard Jones - Long Mountain may be line fed and an 'island' site with dependents but for all organisational purposes it is still a relay of Blaenplwyf much the same as Torosay is organisationally speaking a dependant of Blackhill...

I believe all main transmitters aerials are horizontal polarization and relays are vertical polarization.
Long Mountain is still listed as a vertical polarization.
If they switched polarization then everyone would have to adjust their aerial to get a proper signal.

Mark A.: Also this transmitter only has three multiplexes and is not one of the 81 main Freeview transmitters.

Mark A - That isn't entirely correct some high power relays use HP, Cambret Hill being a good example...

At the risk of hijacking this thread, (Should I start a new one? please advise)
I live in Oswestry, slightly North of the town and approx 500ft ASL. At present I receive good analogue from the Wrekin TX on an old aerial that's been here long before I moved in.
As a welsh speaking Welshman I would very much like to receive BBC Wales etc and have been contemplating buyin a Hi gain aerial to pick up the Long Mountain digital transmissions but reading the above comments I'm thinking that perhaps I'm wasting my time planning in this direction.
Maybe I should wait until the Wrekin fires up to provide me with a decent "English" transmission and buy a suitable new Aerial for that to guarantee good digital reception and try and get the Welsh progs by satellite.
Advice would be appreciated.
