Had an interesting program meeting at the YCARS clubhouse in January. Ric Porter, AA4SC, gave a presentation on DX on 2 meters, bouncing your signal off of the moon to communicate with other amateur radio operators on the other side of the earth. Seems the moon is in prime location on its orbit and is the closest to the earth for a few months. 2 Meters is typically used for short distances for tactical communications and local repeater use. The presentation talked about the theory, software needed, and antenna considerations. Since the signal is so weak, it is considered a digital mode of operation needing a computer interface.
