That's a good point, I noticed that CT & CW pointed to roughly the same tower. There was also a mention of GB7BR which came form somewhere or other. I'm hoping we can use GB7BR for Brighton's DMR repeater to go along side GB7BR. I've updated the spreadsheet to denote redundant data so that can in the fullness of time be kicked into the long grass.
I attempted to attach .kmz earlier, but this forum does not allow files with that file extension. I'll attach the updated spreadsheet in any case.
