The symbol shows the location of the Waltham (Leicestershire, England) transmitter which serves 770,000 homes. 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.

Marie Martin: Film4 is loud and clear in Derby. It might be worth checking that you still are tuned to C57 rather than a possible C39 from Sutton Coldfield if your receiver has been re-tuned recently. Otherwise check for single frequency interference from the RF modulator of a Sky box or VCR. Also try repositioning aerial and HDMI leads relative to the receiver in case there is any interaction with the tuner.

Something is defiantly going on at Waltham, over the past week or so a client of mine has had problems with some channels constantly breaking up while I have not not noticed anything, then yesterday they were all working perfectly for him, there have been lots of reports lately describing the same thing. What's going on???

Ian. You have probably answered your own question. If 'your client' has had reception problems but you haven't, it seems quite likely that there is a problem either with his equipment or local interference.

Ian: Another point being, that if your client happens to reside anywhere in the LE10 area then reception from Waltham is only predicted as being poor anyway due to en-route signal path obstructions, and although many people contrary to the predictors indications might well manage to achieve reasonable reception but what they do manage to receive is not by any means guaranteed as lasting, as in many cases the level that the signals are being received at is not at what could be considered as being a robust level by being not that terribly much above the reception cut off level of their equipment, this meaning that any relatively "minor" variations in transmitter output that would not even be noticed by most would however have more serious consequences to equipment whose reception was near to the aforementioned level.

I live in the LE10 area and my reception is strong. Always has been. He lives in the LE9 area his reception was fine before and after switch over then suddenly for about 10 days reception on some stations was bad, then without doing anything its fine again. Lot's of people have reported the same thing from Walthem. Digital just isn't as reliable as the old analogue was, you only have to read this forum to see that.

Ian: Of course it isn't! as analogue reception can work right down to near zero signal level when the picture can barely be picked out from the background speckles, whereas with digital reception a picture can "only" resolved from between two set levels, namely the lower and upper thresholds, the problem being that under the lower as well as over the upper results in exactly the same symptoms and why set procedures have to be used to determine which applies.
The DUK's reception predictor in common with anything associated with RF signal prediction is never guaranteed to be 100% accurate as RF signals in the frequencies used by Freeview etc cannot ever be accurately predicted, but when transmitter coverage maps do not indicate that the signal being radiated from a certain transmitter covers an area then any reports of bad reception from the said area has to be associated with the fact of it not officially being covered, and as such anything that might be received could be classed as being purely through good fortune.

Another reason satellite is far better

Aerial is positioned on chimney of bungalow. We experience severe signal disruption most days. When retuning topbox signal strength never exceeds 90%. Can you please advise?

Keith Tyler: The signal strength is perfectly healthy.
If this is a variable signal quality issue, then I would suggest that the most likely cause is traffic on the motorway which is crossing the signal path. Multiple lanes means more traffic at any given time which might increase the potential over a single carriageway.
Might traffic tie in with when you experience poor reception? How was it on Christmas Day when, presumably, there wouldn't have been many large vehicles (typically HGVs) about?
Clearly in situations where you have objects crossing the signal path then getting the aerial higher might stand you in better stead to see over them, or at least mitigate the degree to which they may degrade the signal. A bungalow is therefore not as best placed as a house in this respect.
