We were advised that we would have to retune our televisions this morning following changes to the broadcasting situation in our area. We did this but have noticed that we've lost many of the channels we could receive yesterday. Very annoying to say the least! Can you please advise why, every time there are changes to the Sudbury transmitter we lose channels? Our postcode is CM82JS.

Martin Ellis: The most likely explanation is that you're using an older grouped aerial which was not designed to receive the lower frequencies now being used by COM4-6 at Sudbury. If you don't have satellite or cable you should be entitled to have a replacement wideband aerial fitted free of charge, which can be arranged by contacting the Freeview Advice Line (see link below).

Godfrey .Could be you have a groupE aerial . Might be not quite good enough for the BBCB (HD channels) multiplex. A group K or wideband is now needed. If you have no cable or satellite Freeview may be able to provide a new aerial.
