- Antenna for deed restricted lots
pop
- An effective 10-20m DX antenna for deed restricted lots.
The article by K7ZB introduces a simple 10-20m DX antenna suitable for deed-restricted lots. The antenna, a 15' vertical design, facilitated contacts with over 200 countries worldwide. Its design employs a telescopic aluminum tube and radial wires for multi-band operation, requiring an external antenna tuner for optimal performance. The mounting scheme and construction details ensure effectiveness and ease of use.

- 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
