Brianist: the compression can be very bad, I have noticed it too. Faces and moving objects can be reduced to around 10 big squares.

@DJN - your reception prediction for that mux(grouo of channels) is variable. An aerial will help, but it will solve after DSO anyway.

Vicki Harrison: This website has nothing to do with CITV whatsoever. You will have to apply on their website and see if you get rejected or accepted.
Is text language really appropriate?

@Steve:I live quite(very near to you) and Midhurst MUX C and D have always been worse than the other 4.
@Jb38-I'm not predicted to get anything other than 2muxs poor at my location, but I get 4 absolutely perfect in terms oc CNR and BER, 1 good (perfectly watchable, and one variable.

@Mike DImmick-I have two major hills on the way to Crystal Palace, I still get perfect quality on the intended Multiplexes. However, it reduces the strength to the point of barely hitting the threshold even with a stacked pair of Unix 100As.
