Ok, thanks. The frequencies I measured are a few Hz off, but close 
enough. Given 981 (980) for 0 and 655 (652) for 5. Ordering by frequency 
(and guessing the ones not used) would give a code like in the attached 
image. That leaves a problem: What to do with the -1?




At this point I should mention that there is a way to check if the found 
coordinates are indeed the right ones: http://tinyurl.com/3cjo58

I already tried 596 516 and 496 at the end of the north coordinate, to 
no avail.

Any more ideas?

Manuel
