144 MHz low power EME talk on YouTube

On September 7, Bill Keicher KC1HTT gave a presentation on amateur
radio 144 MHz Earth-Moon-Earth (EME) communication to the NorthEast
HamXposition event in Boxborough, Massachusetts

Amateur Earth-Moon-Earth (EME) communications is one of the most
challenging projects that an amateur radio operator can attempt. The
objective of this video presentation is to give the amateur radio
enthusiast an idea of what is needed to successfully model, build, and
operate a small EME station.

The KC1HTT small, low power, 144 MHz, Earth-Moon-Earth amateur radio
station is described.  Included are the physics of EME communications,
site constraints, communication system analysis, design, and hardware
implementation. In addition, the JT65B communication mode, waveforms,
and signal processing are briefly described.

Finally, EME operations are reported including QSO planning, safety
considerations, EME support web sites, with examples of six successful
QSOs and a signal-to-noise analysis of the QSOs based on the bistatic
radar equation. Plans for the next generation KC1HTT EME radio station
improvements are also discussed.
