How Do You Use EME Amateur Radio Communication?
Among the many different modes of communication that amateur radio operators, or hams, enjoy is the weak signal Earth-Moon-Earth (EME) mode. A transmitting radio station will send Very High Frequency (VHF) or Ultra High Frequency (UHF) signals to the moon where they are reflected back to a receiving radio station on Earth. The difficult nature of the EME transmission makes Morse code preferred over voice transmissions. Decide which amateur radio band to use. Many successful EME transmissions are made on the VHF 2-meter band between 144.000 and 144.045 MHz. Set up the radio station for the chosen band including the transceiver, preamplifier, amplifier, transmit-receive sequencer and the Morse code key. Set up the EME Yagi antenna with a movable mount to follow the moon’s track during the transmission. Make an appointment with another ham at a distant location to make an EME contact at a predetermined time and on an agreed-upon frequency. EME transmissions can be technically difficult to
