Simple FM antennas
This directional antenna is typically mounted broadside to the desired transmitter
The Ferrite Rod Antenna
The use of a small Magnetic Loop as an antenna although usually better than a Hertzian dipole
Transmission line transformer
The earliest presentation on transmission line transformers was by Guanella in 1944
Yagi-Uda Antenna
The Yagi antenna consists of a single 'feed or driven element, typically a dipole or a folded dipole antenna

PIC-Keyer This project describes the construction of a real "QRP" keyer with a small microcontroller PIC 16F84, with slightly modified hardware also PIC16F62
