Congratulations to Mark (StationMaster) for being FTF. I can’t believe it has taken over 2 months.
I’ve asked Mark NOT to give any help to anybody, so please don’t ask. However, now is the time to give some hints!
You are looking for 6 2 character combinations, e.g. h4 which means h=4
You are looking for 2 part coordinates e.g. 49.97.abc
You don’t need to look in any of the forums
You don’t need to look at any source code (although it may help)
Everything you are looking for has been on the site since January, so the latest stuff won’t help.
Good luck 🙂
