Here’s what consumers have asked with answers from Radionomy staff and previous consumers.
You are never truly 'done', you are always going to refine the station. But, I agree with the other posters... it's possible to get up and running in a couple of hours, and then refinements will take additional time as you go along.
To cut down on licensing fees, Radionomy has begun blocking reception of programmes in some countries. In some countries, this is a temporary condition until a better licensing rate is negotiated, in others, it may be permanent. If you have a favorite programme, try listening to it from time to time to see if the restriction is lifted.
