The 5 band pipe vertical That's 20, 17, 15, 12 and 10 meters, KL7JR
A simple, cheap and easy to build 33 feet long vertical antenna that works DX on 20 10 meters including Warc bands
The portable random wire vertical
This simple 40 thru 10 meter wire vertical should enable you to get on all the new HF bands
Utilisation d'un pylone autoportant en antenne verticale
It may be interesting to use a high pylon supporting other antennas as a vertical antenna
Una antena hibrida de 3,5 - 7 Mhz que ocupa poco espacio
The occupied surface is limited to that of the roof of the house, 9 x 12 m, and this leads to a very economical realization of vertical antenna for two bands

PIC-Keyer This project describes the construction of a real "QRP" keyer with a small microcontroller PIC 16F84, with slightly modified hardware also PIC16F62
Qrm Eliminetor The principle is based on the fact that the interfering signal from the main antenna coming from the local interfering signal is phase-shifted by means of an auxiliary antenna so superimposed that eliminate the interference
