Hi david au,
Most interesting. including your Legit AM allocations in another of your posts
In the UK, our Government quango Ofcom, would have kittens reading about music on 151 megs band

UK Community Radio, takes Years of 28 day Restricted service, and if you do get a full time Licence
its only 25 watts, and if you use a good site, they make you have directional antenna,
in case you interfere with someone on the next channel 40 miles away

Uk would never use 151 megs, But there is No reason, that we could not use Low band below 87 megs
As a Comms band, its poor in built up areas, would be ideal for Local Community radio
FM radios are already made, for use in other countries, that use below 87 megs for FM

Because UK radio is so restricted and controlled by our Government, to stop competition
Pirate radio on FM is very common in the UK, not just in Urban Cities

Ofcom now trying to stop pirates getting hold of decent transmitters,
so, some will end up with the poorly filtered china made ones, that will cause interference
