thumb|right|DAPNET as of July 2023 ==History== A similar ham radio project called FunkrufMaster was quite popular around 2000. It was based on AX.25-technology and the former Packet Radio Network. Because of the upcoming HAMNET- and IP-Protocol era, a successor was needed. Members of the ham radio activity group at RWTH Aachen University designed and developed DAPNET from scratch as a modern software approach. As of March 2018, over 90 transmitters were already in permanent operation, and the coverage area included parts of Germany, the Netherlands, Belgium, and Switzerland, with Raspberry Pi-based personal hotspots extending coverage around the world.
