NPR New Packet Radio: IP Communication on 70cm Band
Learn about NPR (New Packet Radio), a digital protocol designed for bidirectional IP traffic over amateur radio links on the 70cm band.
NPR, or New Packet Radio, is a modern digital protocol designed for amateur radio operators to transport bidirectional IP traffic over radio links. Optimized for the 70 cm band, NPR allows hams to establish robust IP-based networks, extending the capabilities of traditional packet radio. This mode supports higher data rates and more efficient use of bandwidth compared to older packet radio systems, making it suitable for various amateur radio activities.
Operators interested in NPR can find introductory guides and presentations, often created by developers like F4HDK, that explain the basic concepts and setup procedures. These resources provide practical information on configuring NPR stations for IP communication over 430 MHz, enabling hams to experiment with new forms of digital communication and network building on the amateur bands.

A Quick start guide to NPR New Packet Radio on 70 cm band by the NPR author Guillaume F4HDK. This presentation introducte basic concepts of this niew digital protocol, and guide the user to the first modem configuration both of client and master modems. Includes a final recap of commands. -
An introduction to NPR by Daniel Estevez. In this blog article Daniel EA4GPZ / M0HXM, introduce the new IP communication protocol over the 70 cm amateur radio band. Daniel is an experienced operator on IP on 430 MHz with CC1101 and Beaglebone black project and makes a good comparison of the two projects. -
NPR (New Packet Radio) is a custom amateur radio digital protocol, designed by F4HDK to transport bidirectional IP trafic over radio links on the 70cm band. This IP protocol is optimized for point-to-multipoint topology, with the help of managed-TDMA. Bitrate is up to 500kbps. Home Made modem has a built-in ethernet port to connect to PC. To boost power a DMR amplifier is required to reach 20W. This project is an extension of HSMM - Hamnet - AREDN networks
