I am thinking of of getting a freesat box. According to what I read you will get the correct ITV for your area on 103, But since unlike a sky box there is no card how dose the box know where you are? Do you programme it in your self?
Be aware however that some ITV 1 sub regions are NOT available on freesat and are encrypted and only available on FreesatFromSky boxes - including Central South, Central East, Central South West, Meridian Sussex, Meridian North, Anglia West, Yorkshire East and Tyne Tees South. In these areas a freesat box will give an adjacent region.
Note also that ITV 1HD regions for Central West and Meridian South East are also encrypted and only Granada and London regions are available on freesat.
