The Delaware Packet Network (DEPN) objective is to document and promote the development of a RF-Linked Amateur Radio AX.25 and IL2P (Improved Layer 2 Protocol) Terrestrial Packet Network within the State of Delaware and surrounding areas.

We are interested in building a RF-linked ham radio packet network throughout the State of Delaware using the Terrestrial Amateur Radio Packet Network (TARPN) featuring BPQ Node, BBS and Conference Chat. If you are interested in setting up a TARPN BPQ Network Node, please contact us using the Contact page. More information on TARPN is available at

Every station in a Terrestrial Amateur Radio Packet Network consists of a Raspberry Pi, at least one TNC , at least one radio, and at least one antenna. The Raspberry Pi TARPN architecture is expandable. You can start with one TNC, radio and antenna, and add more later if the need arises.

Each TARPN station serves as a node in building the network. Each node connects to a ‘neighbor’ TARPN node and can be comprised of several RF links, known as ‘ports’, on different frequencies. Each RF link requires a separate TNC, radio and antenna system. Yagis are recommended for point-to-point links to TARPN neighbors. With this scheme, data throughput is greatly increased over a traditional packet system typically comprised of individual packet stations connecting to a local hub/node/bbs on a single frequency.

Two Port TARPN node, ‘BRIANP’ located in New Castle, Delaware. Features Raspberry Pi 3B and two Nino N9600A3 TNC’s.

Port 5 – 145.070 1200 baud
Port 6 – 441.050 1200 baud

The NinoTNC N9600A is a USB interfaced 1200 baud (Bell 202) and 9600 baud (G3RUH) serial KISS TNC designed by Nino KK4HEJ for use in Amateur Radio AX.25 and IL2P packet data networks.
