Dear Sirs

For the last 2 weeks when watching BBC One HD, the sound is cutting off often and to get it back, by switching to another channel and back, the sound will come back. It can start again after another 20 minutes and again.
It is only happening on BBC One HD.
A friend living near Cold Ash has experienced the same problem as another friend leaving next door, he thought that it's TV was going wrong but it is not the case. It does not do it on BBC One SD and any other HD or SD channels.
Can you please check what could cause this problem and come back to me?
Thanks in advance

My post code is RG22 5QW.
I cannot receive channel 108HD on either my Humax 1800T freeview box or my Samsung TV model LT24D390S. In accordance with instructions from Humax I have manually tuned the freeview box but it cannot find any programmes on Channel 32 even though this appears on the list of channels transmitted from Hannington. Can you please advise.

David Williams: The Samsung monitor is simple - it hasn't got an HD tuner. The Humax has two, and Al Jazeera is on Com 7, so if your getting BBC4 HD, you should get it as well, especially since your just 10km from the transmitter. If you have no C32 at all, check that your tuned into that transmitter.

David Williams: a couple of things spring to mind that could affect your ability to receive C32 from Hannington. Firstly is interference affecting the required frequency, either from the rf modulator of a vcr or Sky box set on or arround C32, or radiation from a poorly screened HDMI cable? Secondly is the Hannington aerial connected directly to the receiver, or is it combined via a diplexer with a second aerial pointing to Crystal Palace? If the latter, a diplexer made for the UK would probably split the frequencies to be combined at C38. This would result in the group A leg of the diplexer letting through what little, if any, of the C32 signal that is seen by the aerial pointing to Crystal Palace, whilst rejecting any signal below C39 on the feed from the Hannington aerial.

Location - Ash Vale GU12 5HS

Hello, since early March, myself and neighbours are now getting some from of interference on all 5 programs on the Multiplex where the BBC1 is, from Hannington ( Hannington is the only Transmitter we can see from this particular location )
The Multiplex of 5 channel where ITV is, there are no problems
The Multiplex where SKY News is has the same problems of interference, so it seem to be OK on some and not others. I changed the Aerial to one of the Same ( Wideband Fringe Reception Labgear ) as I thought the old aerial may of got rain ingress. The down lead was new 3 years ago and is a foam filled type.

This happens when the aerial is plugged directly into the back of the Samsung HD TV. I have tried other TVs and the results are the same. I even place a temporary aerial about 15 feet away and use another down lead but it made no difference. ( and yes the TV it has been retuned )

Since the complete change over to Digital I have received perfect Freeview with Strength indications of GOOD and on strength of 96% and Quality of 85%. Even now I get the same reading but get the intermittent sound and blocky picture... It is not a 4G problem as I have tried a filter. Clearly something has changed to a transmission somewhere and the only other nearest station is Guildford which is on a lower power and V polarised.

The only thing I can see is that DAB has come on full power from Hannington but it is a much different frequency and would not of thought it would offer co-channel..

Any guidance would be appreciated... Thanks

john: I dont know about anything else, but a signal strength of 96% is way too high - search for 'too much of a good thing' on this site.

Hi Mike... Well, on a Sig Strength meter ( the cheap one with 4 green LEDS) , I get 2 Green light on the roof with a 1mtr fly lead direct into the aerial which is about midway (60uV) I remember from the old Analogue days I used to look for 1mV :). If I plug just the inner core into the TV socket, I get ITV MUX Ok but BBC 1MUX is obviously blocky. I also have a variable attenuator and have tried that on the main TV input and it makes not difference to the BBC1 MUX... I thought at first it was the High Pressure weather ( I am a radio Amateur ) and I know that with some weather patterns you get what we called lifts so you can contact countries on 2mts frequency when normally you can't...As the neighbours are also getting the same problem and the weather has change a lot since early March I am not sure what to try next. I am not sure if a dedicated Group B would solve it but as it has always been fine I dont see why the aerial I have now should not be OK.. It is trying to find out what has change wit transmission......

I have checked again with neighbours and we are all being affected with this interference on certain channels ( as in my last posts ) It is not Atmospherics as the weather has changed dramatically . If anyone else is in the Ash Vale area ( GU12 5HS ), it would be helpful to learn if they are also having poor receptions on certain channels.. Thanks for a hopeful reply John
