I agree. I hope that Ofcom will allocate some spectrum at around 60 MHz for DRM+ to use, because I think it would be better to leave the FM band uncluttered so that when FM is switched off it can be used for whatever ultra-efficient system has been designed to transmit on the FM band.

One point.

If DRM+ broadcasts did start off between FM transmission, then I don't think it would be so much of a major problem to clear some spectrum when FM is eventually switched off.

Ofcom could simply issue licences with a condition that frequencies can be changed at some future date. Then when FM is switched off they could start moving some of the DRM+ stations, to clear whatever blocks of spectrum are required for any new multiplexed systems.

Come to think of it perhaps they could do something similar when FM licences are renewed. They could perhaps renew FM licences on the condition that frequencies can be changed after, lest say 2020. Then if the decide to switch off FM, some licences will expire, and other can be moved to different frequencies as space becomes available, clearing blocks of spectrum for new multiplexes.
