Communicating over great distances via VHF continues to fascinate many amateurs. EME (Earth-Moon-Earth) communication, also known as "moonbounce", meteor scatter, and VHF cw DX are some of the techniques used. In the case of EME and meteor scatter, the concept is simple: use the moon or the ionized trail of a meteor as a passive reflector for VHF and UHF signals. A simple but effective station is within the reach of most amateur experimenters. With the advent of very sensitive receiving preamplifiers and commercially available high-gain Yagi antennas, many VHF operators are enjoying successful weak signal contacts. With a total path length of about 500,000 miles, EME is the ultimate DX -- for the time being!
