40m-80m ground planes and a squid pole
The antenna is quite simply, a single vertical radiator with 4 radials laying in the ground. The vertical radiator is held up by the squid pole

Antenne double-bazooka
The double-bazooka consists of 1/2 lambda of coaxial cable cut in the center or twice 1/4 of lambda
Antena doble Bazooka para 80 metros
The antenna called double bazooka was designed to be used in radar by the staff of M.I.T.
1/4 Vertical bazooka antenna for the 40m
I needed a omnidirectional antenna for the 40m here is the schema of the antenna
Coaxial Antennas
I constructed a simple horizontal dipole with each half comprising RG58 coaxial cable about 35 inches 900mm long

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
