Hi.
I have not yet made the Jägermeldenetz version of my 'calculator' available.
The full entry for this location is 05 OST SÜD TG, in the 'ordinary Gradnetzmeldeverfahren this would translate to:
O5 OST 303
If You enter this on my webpage, You will be able to locate the center of the 35x28 km !! area defined by this Gradnetz location, which is approximately 20 kilometers north of the village or city Soissons in France.
Regards,
Andreas Brekken
