pete: Basically yes! as although Sudbury (100Kw) @ 22 miles is the more local station, Crystal Palace (200 kw) @ 35 miles away is possibly being received on the rear of the aerial even although its offset by roughly 30 degrees, and so it could well be indicating as being the best signal during an auto-tune.

"Initial set up", "first time installation", or "factory reset" or "default setting" are the terms generally used on equipment.

pete: Did also meant to add, that if the problem is still evident after having carried out the procedure mentioned then the manual tuning in of each of the six muxes will cure the problem. Sudbury's muxes being / Ch44(BBC1) - Ch41(ITV1) - Ch47(HD) - Ch58(SDN / ITV3 etc) - Ch60(11: Pick TV) - Ch56 (15: Film 4).

Just a quick question regarding the channel moves, have noticed that the news channels and children's channels are still operating on there original numbers, even after October 17th deadline, will they continue to do so, had a message come up on screen to say some channel numbers have changed.

Hi
Just to let you know i sorted my Sudbury Ch 60 picture issues...
After reading this and other blogs i realised that my skybox was the problem..When i isolated it Freeview Ch60 worked fine...I then realised the ATV signal to my freeview TV came in on Ch 61...Too close for comfort that one so using the installer page i changed the RF output channel to 69...This instantly made the CH60 DTV signal perfect and the only other thing i needed to do was retune my TV to ATV Ch 69..

I can't get RT in suffolk, this site says i should have it but when I do the postcode checker on the freeview site it doesn't come up. I can't get sky news either (not that I want that right wing Murdoch bllx).

joe: Your reception possibilities cannot be checked on without a post code (or one from nearby) being given, but if using the Sudbury transmitter then RT(85) is on mux Ch56, Sky news(82) being on mux Ch60, and so you should manually tune in each of these two muxes.

By the way ITV4(24)is on the same mux as RT, and if by any chance you are receiving it but not RT then carry out a complete reset on whatever you are using to scrub everything already stored, then follow this by carrying out a normal auto-tune.

I see Sudbury has the fourth engineering works since they supposedly upgraded the service in July. Please does anyone know if so much engineering work is usual, ie, does it denote a problem?

Definitely a problem. All my agro (see 16 Oct post) went away after the last retune but returned at the start of the week. Bloody digital - bring back analogue. I would only miss BBC3/4 and Film 4 they can keep the rest.
