Near braintree - lost all ch 63 last friday - when i think i activated a new channel search as prompted by the tv. So no fim4 for me. I have tried everything including zeroing the memory by unplugging aerial and scanning then re plugging aerial and starting again - no luck. weird thing is was fine past the upgrade date and only went when i rescanned - can anyone explain that ?

Sudbury transmitter Mux COM6 ArqB

I have recently lost all the channels on this Mux, which appears due to low power levels of 1100 watts. Are they intending on increasing the power?

Aerial is on the roof.

Mike Cant: As I previously explained I had the same issue (as do many others by the sound of it) I got over the problem by moving the receiver in question to a TV point that was closer to the aerial and therefore getting a slightly better/stronger signal. The re-tune found the missing channels and then I moved the receiver back to it's original location. This worked! but now and again the picture is a bit flakey on ch63
Hope this helps.

hi Kevin: Thanks for that but i only have one aerial point - comes straight from the roof and into the living room and into the tv. Suppose i must wait until sudbury increase the power - must be hundreds of folk with the same problem.

I miss channel 4 - just like i missed my mate when he ran off with my first wife !! haha

I live in Tiptree. When the Sudbury transmitter switched over I reported that I lost ITV4, Film 4 etc like many others due to a very weak signal. Despite retuning a number of times when prompted by the on screen message I never got them back. However about a week later (after the transmitter in Norfolk switched over I think) I had a reminder come up on my Humax recorder to retune. Upon retune I got back all the missing channels (ITV 4, Film 4 etc) from the Sudbury transmitter - a bit of a weak signal but there okay. Funny thing is I lost many other channels (e.g. BBC 4, ITV 3, 5 USA, Dave etc) from the Sudbury transmitter (signal too weak) but found them all again in the 800 number range from another transmitter (probably from Kent / London). It does all seem a bit of a hit and miss affair but I guess will get better when the Sudbury transmitter power outputs increase next year.

I live in Chelmsford and like many others, lost ArqA (Film 4, Etc) on the Sudbury transmitter after latest re-tuning.

Tried re-tuning many times - no success - then lost ArqB (Sky News, Etc) a couple of days ago.

A manual re-tune said there was a "good signal" for ArqB but couldn't pick up the channels - New flat screen telly - old aerial on the roof.

Same again 1830 yesterday. Tried again an hour later & ArqB was back - still no ArqA.

Somebody must have "tweaked" something !!!

How can the Sudbury Transmitter say its got no reported problems when alot of people have lost channels like yesterday and film4 because it has low power until june 2012.

What a joke when people have lost channels and had the ariel upgraded at cost and had all the channels then lose them because of low power.

Also have to put up with adverts for freeview saying how wonderful they are !!!!!
