The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

By the way I think this page needs updating regarding the output from Walthan on channel 29 Brian.

Steve: You previously said you were at DE4 3ET, is that still the case?
Digital UK don't offer any prediction from Waltham at that address. A look at the terrain shows some very big hills blocking line-of-sight. While signals do refract over terrain, they will always be weaker than if you did have a direct path available.
The Bolehill relay also transmits on C57 and could be generating enough interference to stop the weak signal from Waltham getting through. The problem on C56 is less clear, although it could be down to being adjacent to the HD multiplex from Stanton Moor on C55, and the C57 service from Bolehill.
The broadcasters use antenna diversity - more than one antenna used in an array, or at different heights on the mast - to handle such problems. You *can* do this yourself, but it can be expensive. It's usually a lot easier to go with a satellite service. You can compare the channels available on Freesat, versus Freeview, at Compare Freeview and Freesat TV | ukfree.tv - independent free digital TV advice .
It *is* possible that you have too much signal, which often causes problems for adjacent channels on a transmitter. You did try turning the amplification *down*, not up?

I live in Derby, and I believe my antenna is pointed towards Waltham. The past few weeks we've been getting terrible interference on the BBC channels (BBC1-4, Ceebies, BBC News, etc.). We were using the 800 numbers since they were giving better reception, but now they either no longer come in at all, or have very bad reception. The 'regular' BBC channels have improved slightly, but still freeze up and lose signal constantly. It's also much more pronounced in the evening.
The antenna is mounted on the chimney, and was bought (and professionally installed) only a few years ago when we went from analog to Freeview (now using a Humax PVR).
I don't understand most of the technical lingo on this site, so all this talk about 'C57' and 'Mux', etc. is over my head. Can someone just tell me what's going on with the BBC channels, and will it improve? Is there anything I can do?
Thanks for any help that can be provided.

The BBCA mux on fr 61 on the main Waltham transmitter will possibly around 2013 be relocated to another frequency due to fr's 61-68 being cleared for the 4G mobile phones network.The big question come that time is where will BBCA mux be relocated to,49 possibly as 50 is out of the question due to a clash with Tacolneston ArqB on fr 50 after DSO2,also fr's 53 ArqA & 60 ArqB at Belmont (after Wed 23 Nov 2011) are used !

Mark Fletcher: The "rules" say C61 and C62 get moved to C48-C53, with the displaced service in C48-C53 getting moved to C39 and C40.

Briantist.Thanks for reassuring in relation to the issues surrounding the future relocation of certain mux's on fr's 61 & 62 from certain affected transmitters/relays after DSO UK wide is completed after October 2012,in preparation for the future 4G mobile phone networks.Looking through the link you provided via my previous text,barring any future musical chairs,i can safely assume in the case of Belmont,the ArqA mux on fr 53 and the ArqB mux on fr 60 will remain as they are,fingers crossed !

My mum lives in Littleover, Derby, very close to the Derby relay transmitter and a the top of a slope. To the north and at the bottom of her garden are three small-leaved birch trees, about as tall as a house. Beyond these and going north down the slope are two bungalows. Since switchover, the occupants of these two bungalows say they have worse freeview reception than they had before, and are blaming my mother's trees for interference, to such an extent that she's contacted a tree surgeon to thin the trees.
But I'm not sure the trees are the cause at all. Surely if they had good freeview before switchover they should have it now, with much higher power? My mum did say at least one of the bungalows uses a signal amplifier, which again rang alarm bells with what I've read on these pages. But she also said the same bungalow had had an aerial engineer in to look at their set up, so surely he would have tried taking out the amplifier... wouldn't he?
I realise the properties being bungalows and down a north facing slope will have inherent problems getting good signals from both the Waltham amd Sutton Coldfield transmitters to the south (I don't know to which their aerials are directed) but could the trees actually be the cause of the problem?
Many thanks,
David
