Module SSTV

La SSTV permet de transmettre une image couleur fixe par voie radio. Ce module s'ajoute à votre configuration SvxLink et permet ainsi aux utilisateurs de votre relais de demander l'émission par votre relais d'une image. Par exemple, l'image que vous transmettez peut être une capture d'une caméra ou webcam.
