This is a group which uses ham radio frequencies to tie together a network of Raspberry PIs to create a wide area text/chat and remote control network without using Internet for data links.  They use Internet for discussion, configuration, status reporting, but TARPN traffic is done via ham radio.  
There is a local TARPN with 17 sites in Wendel, Knightdale, Raleigh, Cary, Chapel Hill, Durham, Hillsborough, Mebane.  
TARPN has a web page (tarpn.net) and groups-io chat.  The web page has a recipe and scripts for constructing network sites.  
No dues, no club ownership of anything.   There is a talk about TARPN given at the TriLug and made available by DataKraft on Youtube
