Le satellite Radioamateur AO-7, vient d’avoir 45 ans ce mois-ci ! Il la plus longue dur\u00e9e de vie au monde. Il a \u00e9t\u00e9 lanc\u00e9 le 15 novembre 1974 \u00e0 partir de la base a\u00e9rienne Vandenberg en Californie et p\u00e8se moins de 30kg. <\/p>\n\n\n\n

Apr\u00e8s pr\u00e8s de sept ann\u00e9es de service, on pensait que l’AO-7 \u00e9tait arriv\u00e9 \u00e0 la fin de son existence en juin 1981 en raison d’une panne de batterie.<\/p>\n\n\n\n

Vingt ans plus tard, le 21 juin 2002, un amateur anglais, G3IOR a d\u00e9clar\u00e9 avoir entendu sur 145,975 MHz une balise CW (morse) d’un Satellite OSCAR inconnu.<\/p>\n\n\n\n

Il n\u2019a pas fallu longtemps pour identifier le satellite AO-7, qui depuis reste op\u00e9rationnel lorsqu’il est illumin\u00e9 par le soleil (puisqu’il n’a plus de batterie)<\/p>\n\n\n\n

Mode A Transpondeur Lin\u00e9aire :
Uplink: 145.8500 \u2013 145.9500 MHz SSB\/CW
Downlink 29.4000 \u2013 29.5000 MHz SSB\/CW<\/p>\n\n\n\n

Mode B Transpondeur Lin\u00e9aire :
Uplink: 432.1250 \u2013 432.1750 MHz SSB\/CW
Downlink 145.9750 \u2013 145.9250 MHz SSB\/CW<\/p>\n\n\n\n

Des contacts Europe \/ Am\u00e9rique du nord sont possibles lorsque le satellite est au dessus de l\u2019Atlantique.<\/p>\n\n\n\n
