I see that the DigitalUK site is saying there's a 're-tune event' on 3rd September. Can anybody give any reasons for this please? Thanks Kevin

Have done the September 3rd retune, Sudbury transmitter, but now have no signal on channels 58, 60 & 56. Is this a known problem?

robp: Have just completed a DTV retune (Sept 3) and have lost BBC4 HD and several other channels (especially HD ones are now subject to freezing). Is there a problem with the upgrade? Problems appear on both TV & harddrive box.

Hello Everyone

What a fantastic website! I hope you can help me.

I have recently bought a house in Felsted which is on the overlap between Crystal Palace and Sudbury. I was previously living in another house in the same estate that was rented and had excellent signal from Sudbury.

The house that I have bought had 2 aerials installed: one in the loft (disconnected and pointing roughly east) and one outside on a pole that was in use and pointing South (Crystal Palace)

The signal from Crystal Palace wasn't great, so I thought I would see if I could repurpose the disconnected aerial to recieve from Sudbury. I have reconnected this old aerial and pointed it towards Sudbury. Following a return, I have all the channels except ArqA (Dave etc are missing) all the other channels have 90%+ signal and perfect signal quality.

Where have I gone wrong, and how do I get ArqA?

Richard: That multiplex is on the highest frequency and the most temperamental, if any of the muxes go down, it will be that one, it is a pain in the *. If I use a wall plate instead of the aerial cable straight to the set, that mux [only] goes down, if it foggy, it goes down, if it sunny, it goes down.....
