TARPN - Terrestrial Amateur Radio Packet Network

Technical Overview

TARPN is a project focused on building digital packet radio networks using VHF/UHF amateur radio frequencies. The network uses dedicated links between nodes, implementing modern protocols like IL2P while maintaining compatibility with traditional AX.25 packet radio.

Key Technologies:

• IL2P (Improved Layer 2 Protocol) - Enhanced packet radio protocol
• BPQ Node software - Network routing and management
• TNC (Terminal Node Controller) hardware - RF interface
• Raspberry Pi based nodes - Cost-effective computing platform
• VHF/UHF radios - 2m/70cm amateur radio bands
