Dave Lindsay. Just checked manual tuning again for C48,51,52 ... varies with the weather. And finally found stations on C48 ! (very poor quality)
Actual "Quality" measures upto 19% C51, 9% C52 but still 0% C48. (Not sure if truly 0, my set a bit strange ... always reports 0 for C21 ?)
Gives me more incentive to get a new aerial.
Thank you for you interest.

I am Chris james and my problem now seems solved by the simple expedient of swinging my low roof aerial through 180 degrees and tuning to the Sandy transmitter rather than Oxford:I also get both South Today and Look East news and the ITV meridian news and Anglia News with a perfect picture all the time. Maybe others living in Aylesbury and having problems could try this.

Chris James: I find what you have mentioned rather interesting insomuch that "if" your post code is truly representative of your locality then your aerial is a fraction under 40 degrees out for Sandy, as the predictor indicates Oxford @ 16 mls / 264 degrees and Sandy @ 33mls / 46 degrees from your location.
Of course should the post code be reasonably accurate then that's inclined to indicate that the satisfactory signal you are receiving is via a refection, and so long its of a stable nature all good and well.

Chris James: Or of course looking at it from another angle, being that should the aerial now be correctly aligned for Sandy then it couldn't have previously been for Oxford or vice-versa, or that its simply the case that its a little out on both stations, as the 180 degree turn around would be error free by being directly visual.
Not that this really matters if the reception is satisfactory, as that's all that counts.
Should say though that Sandy's PSB muxes are indicated as only providing variable reception on that code, so keep this in mind should you experience any seasonal induced problems.

Hi I'm in Northampton NN2.
Awful reception on all multiplexes since just before the bank hol - about 1st June, so well after the last Sandy Heath work i think.
Neighbours have the same thing. There are good periods but they never last for longer than a few hours. Doesn't seem to be a pattern in times. What's changed since then to cause these problems? BBC say just manual re-tune your equipment! (52.2369,-0.8974)
