• NPR New Packet Radio - IP over 430 MHz - 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

• 2m to 70cm Transverter Circuit - A 70cm / 432 MHz Transverter Project transverter circuit is an electronic device that converts a radio signal from the 2 meter to the 70 centimeter band and vice versa, allowing a single transmitter/receiver to be used for both bands. It consists of an IF stage, local oscillator, frequency multiplier, and amplifier. The circuit must be designed for minimal signal loss, noise and intermodulation distortion.
