Sporadic E is now open on 10 and 11 meters. The system is based on constant live data from DX-Clusters around the world. We identify the Sporadic E-layer reflection points and bounce the signals of that layer point. You can see the reflection points as big saucers reflecting the RF signal. In the scenario below we show you two Es clouds. The closer the path is to the ES cloud, the higher signal. B/C paths would have good 5/9 signals where as A would hit the Es layer on the rim producing readable signal but lower level. These Es clouds are constantly moving due to the sun's radiation so expect sudden drops in signal.
