The DAPNET (Decentralized Amateur Paging Network) is a network operated by amateur radio enthusiasts. It is the new and further developed version of the FunkrufMaster. It consists of a decentral server cluster feeding paging data to distributed transmitters. The most used frequency is 439.9875 MHz and the protocol is POCSAG. Common paging receivers are of type Skyper or AlphaPoc, but there exist others as well. As it is used on amateur radio frequencies, commercial use is forbidden.
