Jo: others on this forum are more expert than I and will no doubt comment further, but I would just observe that different TVs and set-top boxes can have tuners with very different sensitivities to both signal strength and quality. In my case (set out in previous posts) we had a situation in a block of flats in central Brighton with one shared aerial where, after switchover, some TVs were affected by picture and sound breakup but others were not.
It sounds to me like the tuner in your Alba set top box upstairs might be being saturated by a signal which is too strong. This would explain the picture and sound break-up you describe and perhaps also why you are picking up a signal from a second transmitter (this is why you also have BBC1 on channel 800).
Do you have any boosters or amplifiers between the aerial and your upstairs TV? Try removing them if so.
Failing that, as a quick fix you might also try a cheap internal aerial for your TV upstairs. In Hove you are not that far from the transmitter at Whitehawk and you should get a sufficient signal inside.
Hope that's helpful.

I'm not sure that we ever really worked out what was going on with the signal in my block of flats.
It seemed that the signal I was getting in the ground floor flat was stronger than the signal in some of the top floor flats (which was of good quality too). This suggests to me that there is a further amplifier somewhere in the distribution system and that it was this that was being overloaded and distorting the signal.
The solution has been to disconnect the main distribution amplifier so that it is an unamplified signal being distributed around the building (and then presumably boosted at some point by the secret second amplifier).
But there we go. A simple resolution in the end. Disconnect the amp.
