The Great DVB-T switch off?
Is it true there is a plan in place to move everything to T2 by 2020?
I've not heard of an actual plan, but I suspect there's an inkling that
they'd keep one DVB-T1 mux with all the PSB channels for the luddites,
then convert the rest to DVB-T2, which would increase bandwidth per mux
and cut down on the wasted bandwidth by SD+HD duplicate channels,
probably lose the temporary COM7/COM8 muxes.
