kiwisteve: Yes they did but they would still be able to have their own UHF channel as they had analogue channels

Going way O/T I can confirm that the racing board took up their option to "convert" their existing licence to digital in the past week. What they do with the licences, it will be up to them and there are a number of options they could take, but there is a 2 year implementation obligation none the less.
