Seems the BBC might next year launch spinoff stations, on BBC Sounds only, there is of course a precedent for this with CBeebies Radio, but launching spinoffs of Radios 1, 1xtra, 2 and 3 with the license fee furore still bubbling will be controversial to say the least. The Commercial sector will huff and puff.
According to this arcticle
Ofcom are already being consulted and might approve if these stations are not Broadcast OTA, and only available 'online' in all it's guises.
It's an interesting one to monitor into 2020. It also answers why there appears to be a move to launch BBC Sounds on Connected Devices early next year too.
They could easily just automate it and run it as a web stream through a server.
They don’t need to have DJs or spend any real money on these spinoff stations.
