Bonjour les amis,

Aujourd'hui 17/06/21, la meteo n'annonce pas d'orage sur les pré-Alpes de Grasse...

Je prends donc le chemin du Sommet de Calern, Ref: F/AM-491

Je serai QRV vers 10:30Utc du 60m au 70cm (Dipoles pour la HF, Moxon pour le 6m).

Aprs.fi (F6HBI-7) DMR TG 973, R6 du Mont Vial, R3 Mont Agel.

Sur le chemin du retour, j'irai rendre visite au copains du SHF,
Gil/ F5CAU et Antoine/F5BOF vont tenter des liaisons en hyperfréquences (DUCT) avec l'expédition corse :TK5SHF

Info DUCT:
In telecommunications, an atmospheric duct is a horizontal layer in the lower atmosphere in which the vertical refractive index gradients are such that radio signals (and light rays) are guided or ducted, tend to follow the curvature of the Earth, and experience less attenuation in the ducts than they would if the ducts were not present. The duct acts as an atmospheric dielectric waveguide and limits the spread of the wavefront to only the horizontal dimension.
