Had this discussion at Sywell Rally.....
Spoke to the helpful CAA people and they pointed out that ground stations have another year to comply. So why? Apparently because they are groundbased their range is such that they won't overstep other frequencies in nearby 8.33 spacing. And supposedly they will be encouraged to change sooner as cost of 8.33 licence is cheaper than 25.
Without saying as much, they indicated they expected lots of pilots to be operating illegally for some time to come after start of Jan.
I await Jan 1st eagerly, to see just how many people/places can hear me and how many I can hear!
