Antenna 80 meter Links →
Sloper per 80/160 lunghe solo MT. 17,50
This type of antenna has been installed for more than a year with interesting contacts on both bands
80-160 antenna for the small garden
I decided to make a trapped 80-160 meter vertical dipole with the feed point at 11 meters
80-160 metri
This antenna is to be used in a small space available
Antenna for the Low Bands..80 and 160m
I'm now using 45ft dipoles. loaded top and bottom cap hat wires on 80 and 160m, suspended from a 60ft high timber mast

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
