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
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
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
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
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.
