 # Glühwein-POTA und Jahresrückblick 2022

 Das Jahr 2022 war für uns ein ganz besonderes. Eine Gruppe von Funkamateuren hat sich auf Twitter zusammengefunden. Vereint hat uns das Interesse an Outdoor-Funken, insbesondere SOTA und POTA.
 Die ersten gemeinsamen Aktivierungen im Hamburger Raum haben wirklich Spaß gemacht. Wir haben viel gelernt und den ein oder anderen Funkamateur fürs Draussenfunken begeistern können. Schnell war klar, dass Twitter nicht das richtige Medium für Gruppenkommunikation ist, also sind wir auf eine Chat-Plattform umgezogen.
