March 5 Program: TARPN

Tadd, KA2DEW, will be at Bullocks this Tuesday to talk about what VHF/UHF packet radio is, what operators of a TARPN station see, what hardware it uses, what people do in the group, and how to join in the fun. We'll have a couple of systems, radios, Raspberry PIs, antennas and a very short slide show.

History:
A local group Amateur Radio project has sprung up over the past 5 years called TARPN. The project uses packet radio in a new way to do live chats between the participants over a four county area here in Central North Carolina.

Just as DxCluster, APRS and working digital satellites are all different ways of using packet over VHF/UHF Amateur Radio, TARPN has yet another. TARPN is building an off-the-grid text chat network which is attractive to builders, tinkers, preppers, VHF enthusiasts and especially to young adult hams.

The Central North Carolina TARPN has 22 on-the-air stations between Wendel and Mebane. There are TARPNs in NC, Pennsylvania and Michigan and experimenters in a few more US locations including Puerto Rico, as well as in England and Japan. The TARPN email reflector has 140 participants world-wide.

Two interesting elements about the TARPN project are that they've overcome the saturation problem where packet radio networks fail when they get too crowded, and TARPN permits (nay, insists) that each and every participant have a fully expandable piece of the network. Nobody is a dependent. Everybody is a builder.
