[amsat-bb] South American station on AO-7

Good evening,

Just after AOS on AO-7 this afternoon around 2117Z, I heard a station calling with the suffix RAS. He never was heard after that. I was just curious who that could have been. I assume it's a station from South America and I heard him just before his LOS. Anybody have any ideas?

73,
