In the UK 8m is unavailable to the amateur radio service. Instead people have to apply for an I&T licence which costs £50 every year.
To my knowledge 5 EU countries plus South Africa have granted amateurs access to this band, usually with some restrictions. There may well be more. Many more have given experimental access outside of the amateur radio service
Judging by the ease that OFCOM have issued I&T licences, often with high power, all modes and wide frequency coverage and zero traceability (no callsigns needed), they do not seem to be the block. It looks like the RSGB is dead against it!
This is very very sad when, especially in the years around solar maximum, so much research and experimentation would have been possible.
Earlier this week I wrote to the spectrum committee and the general manager asking them to try and get behind the push.
