Here is a copy of the preliminary bandplan for 146-147Mhz and it would appear to be digital only!

Now speaking for my local area, there are NO stations who actively use digital modes so it is difficult to see what the point is of allocating 1Mhz of prime VHF spectrum in this way.
The frequencies may as well have been given to CB operators who would love a VHF allocation and would certainly make good use of it.
The current situation is a complete waste of time as far as I see it!
There may be a handful of people who will jump at the chance of using wideband digital modes on these frequencies but with all the other (Higher) frequencies available to this small group why would they need any more spectrum?
