I don't know why you don't all get freesat!
This changeover is a farce.

Is anybody aware of any plans to broadcast all channels in HD in future as this would have further ramifications for people even with digital TVs (without a second tuner),ie yet another box and more expense even though you are getting more than acceptable picture quality and don't neccessarily want it anyway?

Thanks for all the info herein. I had just complained to Digital UK and have written to my MP complaining about the total chaos of this DSO, my loss of channels and the outright lies which have been propagated. I could not understand why many of the digital channels which I had been able to receive from Sudbury prior to DSO were not now receivable! From this site I have learned that the reality is that this is because rather than being increased as Digital UK claimed the transmitted power of many channels has in fact been reduced. No wonder it is more difficult to receive good digital transmission signals where compared to analogue the transmitted power has been reduced by 150%! Digital UK claim that Ofcom state that the Sudbury power has been increased by a factor of 10 for all channels, which I now know from here is a lie!

The government and Digital UK have told a pack of lies rather than the truth, and those people who have been entrusted to organise this DSO clearly would not be able to organise a proverbial piss-up in a brewery! So thank you for your help in enabling me to understand why the problems exist, and exactly what they are.

Did anyone else lose all signal on these from just before 1am till 1.25am on Sudbury?
SDN and ARQb WAS PUMPING.

Dr. R. D. Feltham: I am very unsure why Digital UK would have not made it clear that the Sudbury switchover would have the effect that it did. Can you provide a link to a place where such misleading information was given out?

I have a Samsung TV with Freeview built in.
I have my original analogue aerial on the roof.
Since DSO the only channels that i can see on Freeview are Yesterday, Film4 and a couple of shopping channels.
If I install a new aerial will I get more stations? Or should i be doing something else.
My postcode area is CB8.
Any advice would be much appreciated.

James Clifford: No, you should wait until the end of November for the multiplex to move to the new frequency as this will restore your service. A new aerial would be a waste of your money.

James Clifford: Can you get the BBC and ITV channels at all? Did you have digital TV before switchover?

If you had digital before switchover, and you can't get BBC channels or ITV, *and* you had poor analogue reception before switchover, there's a possibility that you actually had the wrong group aerial for Sudbury. It could have been a group C/D. This particularly might be the case if best analogue signals came from a relay, and the aerial was moved around to point to Sudbury for digital. You need a group E or wideband aerial (which cover groups B and C/D) for all services from Sudbury.

If you had clear analogue reception before switchover, you may now have too much signal, causing the signal to be distorted and undecodable. If you have a booster or amplifier, try removing it or turning it down. If you don't have one, or that doesn't help, try adding an attenuator.

If you do have the channels listed above under PSB1/BBC A and PSB2/D3&4, it's likely that your aerial is a Group B (which was all that was needed for analogue reception). A change to a Group E or wideband is likely to be necessary for reliable reception of the commercial multiplexes, both at their current temporary location and their final homes.

I would have expected you to have most trouble with ArqB, which carries Yesterday and Film4, because it's on the lowest power level. That may well point to it being a problem with too much signal.

We need a full postcode to see what the prediction for your location is. A postcode area covers hundreds of homes and usually a few miles, so isn't precise enough. UHF reception can vary greatly over distances of only a few metres.
