Au passage, j'ai pu trouver une liste des radars météo en Europe
données en KMZ, présentées sur une carte où dans une interface maison.

http://www.knmi.nl/opera/euradars3.html

La bande qui nous intéresse est la "C band" chaque radar présente des 
contacts administratifs, sa fréquence précise et son rayon d'action 
approximatif. Pratique… Rien ne dit que ça ne soit exhaustif de l'usage 
radar de la bande 5GHzet ça n'enlève rien à la nécessité légale 
d'activer la DFS ceci-dit… Comme disait burban, y'a peut-être du militaire.

Ciao,

Jocelyn
