It may be because the C68 multiplex is at the extreme end of the spectrum. Here in Banbury it's the only multiplex that disappears during bad weather. I would expect after switchover everyone will have rock solid reception of all channels without problems.

An extra problem for people in Banbury, is that if you draw a line from us to Oxford, then keep going, you hit the Assendon transmitter. And that broadcasts BBC2 Analogue on C68. So 'good' atmospheric conditions result in Oxford's C68 getting drowned out by the analogue signal from Assendon. While 'bad' atmospheric conditions means we don't get the signal anyway. So we only get C68 when the conditions are 'just right'.

This *WILL* change after September, when Oxford stops using C68.

Jay Blanc: Assendon transmits at 8 watts, is vertically polarized, and its aerials point east. In no way can it possibly 'drown out' transmissions from Oxford.

It's also the wrong side of the Chilterns.

It's much more likely that in 'lift' conditions, you're picking up the Channel 4 signal from Midhurst (57 miles away, so over the horizon, but 100kW horizontal) bouncing off the atmosphere.

There are no other co-channel problems between Oxford and Midhurst.

Thursday 17 March 2011 3:55PMHi people....I live in Swindon (SN)post code and have been following the comments with ref to channel loss and various other problems.Would i be wrong in asuming that after september 28th everything will be hunkey dorey or is this the way DTV is gonna be in the future?.

Adey mate, I'm afraid IMO you would be wrong to assume everything will be Hunky Dory after the 28th. This is what DigTV is all about. Lovely when it's working and rubbish when not. It's like a light switch in a room. On or off, all or nothing. Unlike analogue which I liken to a dimmer switch. The signal may be reduced but you can still see it! Colin @ GL7

Whilst it's true that digital signals, when degraded, produce pixellation and sound blocking which viewers find unnatural - whereas analogue suffers from snow and multiple imageing. This is why DAB sounds so bad when the signal is weak - weird bubbling mud sounds instead of the background hiss which humans find less intrusive. But people have become so accustomed to high quality TV now, that even the slightest digital dropout becomes intensly annoying. But digital receivers have built-in error-correction systems which attempt to recover lost transmission segments and usually do so very successfully until they cannot cope as the signal drops off the 'digital cliff'.

However, Oxford Beckley's performance should improve massively with the power increase and frequency changes scheduled for September 2011.

Analogue signals in East Witney are pretty poor; however, I've been very impressed with the robustness of the digital signal, if less so with the unnatural artefacts that are a characteristic of many digital broadcasts. Hence the need for 'HD'; non-HD TV could have been broadcast in 'DVD quality', but commercial greed has pushed for quantity, not quality and we have a plethora of rather indifferent channels as the result...

Mick H: I can't see any reason why you should not get those channels reliably right now. It's most likely that you have too much signal rather than too little, and this means it will probably get worse after switchover, not better.

You should remove any amplifiers that you have, and try adding an attenuator.

Is there anyone else in the OX28 area suffering awful digital reception? Periodically, on some channels - ITV1, ITV2, ITV3, E4, C4, to name the very worst - the sound deteriorates to untranslatable, and the picture disintegrates and pixelates. This has been going on for absolutely months and we're at the end of our tether with these issues. Our full postcode is OX28 5JJ, if that helps. We've checked everything, retuned everything, in fact the only thing we haven't done is set fire to the TV and tuner.
