Are there plans to convert the Freeview radio channels into TV (Q and Kerrang)?
No, there is not enough capacity on Freeview to turn these radio stations into TV channels. You can fit around 25-30 radio stations into the capacity required for a TV channel.
I understand that some channels may add more text and interactive elements in the future.
There are still plans for a "minority sports" channel, but no start date has been given.
