My mother lives in retirement apartments in Rushden,Northamptonshire. Following the last changes to Freeview in July, when there were messages advising everyone to retune their televisions, she has lost a number of stations. She informed the Estate Manager that she and other homeowners were unable to receive all the Freeview channels and he stated that he had consulted a Freeview expert and that the channels would return eventually. He advised her to retune every day, which she has done, but she is still missing a large number of channels. Can you advise please. Is it the case that the channels will return eventually? I live in close proximity and receive all Freeview channels .

Jayne Hilton: Retuning every day is pointless and won't restore the missing channels unless something else changes. It's quite likely that your mother's apartment has a communal aerial system which may need to be modified following the recent frequency changes. You should go back to the estate manager and insist that they get someone out to sort it out and stop trying to fob people off.

Hi my postcode is NN1 5RN
I have recently lost several free view channels 11, 12 , 40, 41, 48.
I have done a complete reset but no improvement.
These channels were fine until a few weeks ago.
I have several tv's and this problem has suddenly occurred on all of them.

Robert Corns:

Do you have a wideband aerial fitted? Without one you will have problems receiving some of the programmes from Sandy Heath transmitter.

Robert the coverage checker indicates that at your location you should get a good signal with a medium size wideband aerial. I assume that you already have a wideband aerial if you used to get all the cannels listed on this page . The channels you lost are in mid band so I suspect a fault in your wiring. or if in the loft the aerial is in a poor position.

Since last retune I haven't been able to get anything on C21 so no HD progs. I could get these before the retune. Is this down to my aerial ? Also thought I should get something on C36 C55 C56 but nothing. Looking at the channels above I don't think these are available but would like to get HD progs. My postcode is PE13 5LB.
Thank you.

J Knights:

Look at the Digital UK Coverage Checker results shown through the blue 'digitaluk trade' box below your posting or at Coverage Checker - Detailed View This shows that many of the transmitter signals have some potential problems but you should be able to get all the channels if you are using a wideband aerial (that need changed at an earlier transmitter channel reset to allow for the extension of mobile services).

That page mentioned also shows the correct channels for the available transmitters and the direction that your aerial needs to be aimed to get them.

J the coverage checker shows you should be able to get most of the channels from Sandy Heath . You are in range of some other transmitters so you may have to tune in manual mode to be sure of getting Sandy heath . I think a good outdoor wideband aerial is essential in such a complex multi transmitter area.

The Digital UK Coverage Checker for your location, see Coverage Checker - Detailed View shows that reception of COMs 7 & 8 from Sandy Heath to be variable. Therefore it is unlikely that you will get reliable reception of any of the programmes carried on those multiplexes.

The alternative transmitter at Sudbury does not carry COMs 7 & 8 so does not transmit those HD coded channels.
