Within the last few weeks a massive wind turbine has been erected approx. 4km from my house (LU7 2RH), in a direct line with the Sandy Heath transmitter. Ever since it has been operational, presumably when the turbine is facing, we get a pulsing break up (at about the rotational speed) on some channels, especially those on COM6. I notice that COM6 is about 2m lower on the mast than most of the other multiplexes, so perhaps that is significant. My question is, am I able to claim compensation from the owner/operator of the turbine (who is presumably making quite a lot of money from this) to change my aerial, or raise it up? If so, who should I approach? Any help would be greatly appreciated. Thanks!

Hi Richard - you might be advised to change to the Oxford Transmitter - this will involve turning your aerial round......

Hi Bob - thanks for the info, but unfortunately there is a hill behind my house which blocks Oxford. All the houses in the road seem to use Sandy Heath anyway. Strangely I've discovered that my house is exactly in line and half way between Sandy Heath and Oxford! As it happens, over the last week since I posted, there has been no interference - perhaps it's because the wind isn't blowing, or it's in the right direction (for me!). All the best, Richard

For the last couple of weeks we lose freeview channels Pick, Really and Movie-Mix when we turn TV off. We then have to retune everyday when we turn the TV on. Our aerial is only a year old and we've never had a problem before. Is this caused by a receiving problem from the transmitter?

Nikki Leone: These services are on the multiplex (signal) COM5 which is found last during the tuning scan. Sometimes what you describe happens because there isn't enough memory to remember all multiplexes, the symptom being that the one picked up last is forgotten.
You might find that it is storing signals from other transmitters and that preventing it from doing so will mean it won't forget COM5.
How you might achieve this depends on whether your TV has manual tuning and, particularly if not, what the unwanted signals are, the latter not being able to be ascertained without knowledge of your location.
If you have manual tuning then run the automatic tuning through with the aerial unplugged so as to (hopefully) clear everything that's stored, or there may be an option for this. Then tune in the channels:
PSB1 - BBC One - C27
PSB2 - ITV - C24
PSB3 - BBC One HD - C21
COM4 - ITV3 - C51
COM5 - Pick - C52
COM6 - 4Music - C48
COM7 - BBC News HD - C32
PSB3 and COM7 are only applicable if you have a HD receiver. COM7 may be unavailable as it's on lower power, whether you had it previously may be an indicator as to whether this might be the case.

Nikki Leone: Let us know if the manual tuning trick works.
Knowing your location you may be picking up Crystal Palace and its frequencies and interleaved with those of Sandy Heath so it will be nigh on impossible to avoid it by repeatedly unplugging and plugging in the aerial (because they are so close together).

On Thursday 19 February all my freeview channels disappeared or just turned into a complete mess of broken up images. It's as if the signal has gone through the floor. I retuned and that just made it worse as the weakest ones have been dropped completely.
My aerial is pointed at sandy heath with no issues for 13 years since I moved here (near St. Neots).
Could something have gone wrong with the transmission or some new interference occurred? Maybe 4g mobile?

David Nash : The problem referred to was likely to have been caused by reasons related to atmospheric pressure, as according to last Thursdays (19th) tropospheric index map, a wave of high pressure swept (diagonally) over most of the Anglia coverage area on that day, with it stretching right across Southern area's as far as the Isle Of Wight.
