Antennas : Loop
  • Cheap antenna to make from 160m - 6m  pop - The antenna is nothing more than a simple 2.4 metre square loop drawing pinned to the internal brick wall of the spare bedroom. Yep, thats right, the inside wall of the spare bedroom - ideal for flat dwellers, hotel rooms or whinging neighbours, The loop has a simple switched inductance at the top of the square loop and uses a simple coaxial stub to tune the antenna. An additional variable capacitor placed across the feedpoint can be used to fine tune the resonance of the antenna, by Andy G0FTD

Operating Modes : NPR New Packet Radio
  • 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

  • AZMap - Azimuthal maps generator - AZMap is a freeware Windows program for the Windows PC which will generate, display, and print an Azimuthal-Equidistance (A-E) map of the world, centered at any point on the surface of the earth (except very near the poles). The A-E map is also known as a Great Circle map since straight lines from the center point to any other point always fall along a great circle path and represent the shortest distance between the center and that point
