Le digipeater fonctionne depuis quelques temps et en cas de coupure secteur il red\u00e9marre correctement. Et avant de traiter le sujet des statistiques de r\u00e9ception\/\u00e9mission, j’ai \u00e9cout\u00e9 et enregistr\u00e9 pour vous quelques trames APRS ce jour.<\/p>\n

Sons aprs par F8EBY<\/p><\/div>\n

<\/p>\n

Pour \u00e9couter, baissez le son de vos haut-parleur et lancez la lecture du fichier mp3 disponible sur le lecteur ci-dessous :<\/p>\nhttp:\/\/www.f8eby.org\/blog\/wp-content\/uploads\/2016\/10\/aprs.mp3<\/a><\/audio>\n

Gr\u00e2ce \u00e0 l’utilitaire multimon<\/strong><\/a> on peut d\u00e9coder ces sons vers des trames AX25 sous Linux. Pour m\u00e9moire la commande est :<\/p>\n

$multimon -t aprs.wav -q<\/strong><\/pre>\n
Et voici le r\u00e9sultat :<\/p>\n
