On 15-Feb-2009, Andy GD0TEP and Willems ZS6WAB completed the first 4m "moonbounce" QSO, see http://www.gd0tep.com/wsjt/4m/World_1st_on_4m.htm
Andy says on his website that following tests carried out by himself and GD4GNH back in 2006 ( http://www.gd0tep.com/wsjt/4m/eme_on_70mhz.htm ), he finally found a suitable station to try for an EME contact on the 4 meter band. As a result, Andy and Willem, ZS6WAB in South Africa tried an EME sked on Friday evening, February 13th 2009. Unfortunately, his mast mounted transmit and receive relay failed due to water ingress.
Their 2nd try was the morning of February 15th. Visibility of the Moon at Andy's location came at 00:38 UTC and at 01:34 he received his first moon echo. About a minute later, Andy and Willem completed what both operators believe to be the world's first 4meter EME contact using the low noise JT65a digital mode.
