Homebrew a Half-Wave Dipole Antenna calculator
The following program will calculate the lengths needed to construct several popular wire antennas
How to build a G5RV Transmitting antenna
The G5RV is an easy-to-build 80-10 dipole requiring no traps. All bands, are covered, including 30, 17, and 12
Il dipolo semplice
La piu' semplice, efficace ed economica delle antenne,il dipolo consiste sempre in un tratto di cavo elettrico pari alla meta' circa della lunghezza
Inverted V Antenna
This antenna gets it's name from the shape,recommended height of 1/2 wavelength above ground

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
Voice Recorder Gestito dall'integrato in questione ed offre la possibilità di registrare più messaggi per una durata massima di un minuto con buona fedeltà di riproduzione
