If the moon is closed to the sun or in front of the milky way: forget EME (high background noise).the "good old" VK3UM-moon-planner ( download from SM2CEW's homepage ) Get a software to calculate the position of the moon (azimuth/elevation), e.g.most important: a good receiving system which includes the antenna design, the preamplifier, the connection between antenna and preamplifier, the receiver itself and the "human factor" (training to detect weak signals).EME has been tested sucessfully on all amateur radio bands from 50MHz to 24GHz.Radio signals are beamed towards the moon and reflected back to the earth.With the same antenna and "qro" I managed to log 100 different initials. However, I remember my first contacts more than 15 years ago on 144MHz with real modest equipment: 2x 3.2wl yagis, 180W, no elevation. Graphic illustration of echo.mp3 (screenshot of Nero Wave Editor)ĮME has always said to be "the summit" of V/U/SHF dx-ing. Rx: 1st stage FHX35LG cavity preamplifier, 2nd stage MGF1302 stripline, transverter 28-432MHz, 250Hz if filter, 100Hz af filter Tx: 400W at antenna 4x 24 element yagi (5.4m boomlenght), open wire feeder. To get a taste of it listen to some audio samples.
