What is SPROING?

The Social Packet Network Operators In North Georgia (SPROING) are in the early stages of building a new kind of packet network in the greater Atlanta area. Unlike packet in the 1980s and 1990s, this network actually works, boasting low latency and high (for packet) data rates.
Using the TARPN architecture and hardware models, our goal is to assemble a social network of like-minded radio amateurs via an all-RF network, keeping the radio in amateur radio.

Social network?

Yes. Using the TARPN HOME App, which allows any device with a browser to chat with others on, and interact with, the network and its facilities, participants can join local network operators in a continuous packet-based Social Media roundtable. Unlike other forms of Social Media, this one is for hams, by hams, and non-toxic.

What else is there to do?

While the social Chat system is a nice way to spend some time, most of our users very much enjoy using the network as a software playground and learning tool, where experiments can be run and applications can be tested, including those specifically for the network as well as most anything else. Many of our apps are written in Python, C and Bash, but if it runs on a Raspberry Pi it's likely good to go. Not to mention that these apps are generally on the node and openly inspectable, as is the network itself.

How is a TARPN Network different?

Unlike networks of old, we maintain high (but easily attainable) standards for the network architecture. From an RF point of view, all links are dedicated point-to-point links. There are never more than two stations on a channel, ever. Only radio links are permitted – there is no challenge in using the internet, is there? And, we all run the same basic hardware and software. Because of these (and other) rules, the network performance is far better than you might have ever experienced while technical challenges are minimized.

Where are the User Ports?

There are no user ports in a TARPN Network. Each participant is expected to build and operate their own node, linking to others to expand the network. By insisting on this, we ensure everyone has high-performance access to the entire network.

What do I need to buy to build a TARPN node?

How much does this cost?

Believe it or not, the most expensive part is usually the coaxial cable. A typical TARPN node consists of a Raspberry Pi 4B (1GB) for the node ($35), one or more NinoTNC Modems (~$50 as a kit), a radio for each link (often $10 at a hamfest - we have some to loan), some power supply items (~$50 including battery backup & fusebox) along with antennas and coaxial cables. A typical two-port node can be built for well under $250 (without antenna supports) if you have to buy everything. And, we have many of the things you’ll need and can loan them to you as you get started.

Can I use a digipeater with my TARPN node?

Technically yes, but this is awful for performance. You cannot configure a network route through a digipeater, but it is possible to make a manual connection to a non-TARPN node outside the network and include a digipeater in the address. However, we very strongly discourage this practice, as that channel will fail as the load increases even a little.
Better would be to convince the Digi’s operator (even if it’s a government agency) to join the TARPN network. There are many advantages, particularly in terms of performance, such as in an emergency situation.

What are the rules for TARPN?

Taken from https://tarpn.net/t/faq/faq_rules_for_tarpns.html.
Go to that URL to see links to more information about the reasoning behind each rule. TARPN has existed for 10 years, and we do not suffer from any of the ills known from the early days of packet because of the dedicated point-to-point link RF architecture. We know this works.

1. No non-Amateur methods for data, sourcing, delivering or relaying our traffic. Licensed Ham control-operator copy-and-paste text is the only permitted linkage.
2. All links are dedicated point‑to‑point links.
3. Everybody runs a Raspberry Pi G8BPQ node.
4. Network configuration is open. We will go to great strides to make it possible for every participant to inspect every node.
5. Don't mix Individually sponsored networks with Big-Money sponsored network.
6. These rules are enforced by separation from the network.

Where can I go for other questions and general support & assistance?

A good start is the TARPN Discord server, where a worldwide group discusses TARPN and packet. Ask any TARPN Sysop for an invite. There is also a TARPN Group as well as a NinoTNC group on Groups.io. Again, just ask any TARPN Sysop! In general our contact info is good at QRZ.com
