Hi all, first post.

Anyone able to tell me why 5815-5850MHz. is unavailable? It’s available in 1.2.2
I’m in the UK

Thanks

I too should like a clear explanation -there seems to be a muddle re Regulatory Domain =United Kingdom OR Regulatory Domain =United Kingdom Licensed and although the Channels and Tx Power change they are not quite what I would expect 'at the top end’
Thanks
