[cma-l] OFCOM Press Release - Future of FM Band

[London Chinese Radio]

I notice that they keep talking about "existing" FM stations.
Does this mean that they won't be considering allowing new stations on to
the airwaves?

A clear picture is emerging that it is not merely about inefficient
management of currently available frequency space, and more about limiting
the amount of stations that can go on air.

Furthermore, this would be consistent with attitudes from the BBC and the
commercial radio sector, which clearly exert a heavy influence on Ofcom, a
regulator captive to external commercial and political interests.
