Hi,
I live in the SS0 post code area before DSO today I had a decent signal across the board using a high gain wideband Ariel pointing at the Sudbury transmitter. However, since retuning this morning the signal on channel 50 is very flaky al the the others are fine, is there any reason for this?
Thank you in advance

My digital aerial is on our roof. Before switchover I could get more freeview channels than I can now. Now all it does it break up and some previous channels I now cannot get.
Is the signal likely to get any better.
My neighbours freeview is the same!

I have watched Anglia News on analogue TV at 6pm for years. When I had a new aerial 2 years ago I made sure it would cover Anglai when the change took place.
I retuned my Freeview box today and now cannot get Anglia on either analogue or digital. I have manually tuned the Sudbury Group 34,41,47,49,54 and 50 as advised by Digital Tv but still no Anglia. How do I get it now please?

Retuned about an hour ago. I still seem to be missing the "MuxD" channels. With all others, I'm now getting the expected high quality and strength signal.

Keith Hook: The trade predictor does not indicate reception of Anglia as being possible when using the post code provided, at least not at the very low levels being forecast for of the only three Mux's shown, these being Ch's27 - 24 - 21, with the first two being poor and the latter variable.

Sudbury indicates good reception on Ch's 44 - 41 - 47, with the other two Mux's Ch49 being variable and Ch54 showing as poor, something that unfortunately does not show any signs of improvement until 27th of June of next year when channel changes and power up enables all six Mux's to be received, the changes concerned really only being associated with the latter three Mux's.

Dave W: If referring to Sudbury, MuxD(Ch50)hasnt actually changed as far as its power is concerned, this very low compared to the main Mux's, so if its reception wasnt good before then nothing has really happened that will change it.

jb38, Keith Hook: The Sudbury transmitter transmits the Anglia region, and the probability of reliable reception is VERY HIGH - not 'not possible'. I assume you're referring to the probabilities for Sandy Heath, also part of the Anglia region.

Keith, are you missing any other channels or just those on Mux 2/D3&4?
