Mike Dimmick,
Not sure what's changed since last night but yet another first time install this pm picked 53 and 57 from Cefn not the Wrekin which it was doing last night.
This site is still showing 53 and 57 as low power from the Wrekin so with my experience that has to be incorrect but I've got the Welsh stuff in the 800's so I'm happy.

Thanks for your help
