Those OfCom fellas have formally opened the bidding for the second nationwide digital radio multiplex, the winner of which will be able to operate up to ten stations that will be accessible by DAB radio set owners all over the country.
There is currently just one national digital radio multiplex which is owned by GCap. The new service will have to commercially complement GCap's output (GCap tried to stop there being a second multiplex at all, of course, on the not altogether un-understandable basis that they were told there wouldn't be a second when they bid for the first).
Channel 4 and National Grid Wireless (one of the founding shareholders in Freeview) are two of the main contenders who have said they will bid for the multiplex, though a consortium of BT, Arqica and the aforementioned GCap will also bid.
