I know this has come up previously and the answer then was OP24 firmware supports these channels with UK regulatory domain set. I believe the open source drivers correctly support these channels and as of 2020 these channels are permitted to be used in the UK without license or DFS checks. I also know not many manufacturers actually support them.
My preference would be to stick to a stable FW, but as far as I am aware the proprietary drivers do not support these channels in the UK. Is this something that is likely to change in the near future? I think I know the answer but thought I would ask anyway ![]()
