Versio 19. joulukuuta 2010 kello 19.58
Scripti joka tutkii OH6RUC toistimen linuxissa /tmp/aprs-rf.logia. Jos logissa näkyy APRS-asema joka on lähempänä kuin 30km OH6RUC toistinta ja kyseistä APRS-asemaa ei ole kuultu edellisen 24h kuluessa, ja toistin on vapaana, scripti aukaisee toistimen ja mainostaa toistinta APRS-asemalle puheella. Puhe generoidaan festival puhesyntetisaattorilla.
