Jackie Miles:

According to the Digital UK Coverage Checker, you are just 18 km from the KLnockmore transmitter, see Coverage Checker - Detailed View The channels used are: 31, 37, 29, 33, 36, 48. It is likely that you need to be using a wideband type aerial aimed at the transmitter on a bearing of 138 degrees.

When you say a " normal arial (sic)" ( you actually mean a normal aerial) do you mean one mounted externally on a roof or chimney stack or an indoor type? The indoor types will not be much good in your location so you need an external one properly mounted and aimed.

Jackie Miles: When you say a normal aerial, do you mean an indoor aerial or a rooftop/loft aerial. You're predicted to get a strong signal from Knockmore (18km away) so a decent rooftop (or possibly loft) aerial should be fine.

All HD channels have voice issues. The sound doesn't match the picture. Tried the reset etc, not fixed. I am reading numerous reports of other people in the same area with the same problem. I have 3 tvs in the house, all modern flat screens with built in Freeview. This issue is affecting them all.

R Turner:

The Knockmore transmitter is currently listed for Planned Engineering with Possible effect on TV reception "Possible Pixelation or flickering on some or all channels".

This is probably what you are experiencing. It's worth checking all your coax connections etc. if the signal is weak, bad connections will not improve the situation.

If there are no problems with knockmore why have I had black screen with no signal' since 21st May. FreeviewAdvice have advised me via e-mails that they are aware of problems yet still other sites indicate that there are no problems. Why are viewers not being told about current problems. My local MSP Richard Lochhead has been contacted and he in turn has contacted your CEO. Come clean tell it as it is and DO something about it.
