This App displays on a map Amateur Radio contacts made within the last hour on the 6 m band (50 MHz) in Europe. Es contacts via the sporadic E layer of the ionosphere are shown in red. Sporadic E propagation on the 6 m band happens quite often during summer and at daylight time. This app just displays Gabriel Sampol´s EA6VQ web page at http://www.dxmaps.com/spots/map.php?Lan=E&Frec=50&ML=M&Map=EU&DXC=N&HF=N&GL=N without any modification like any web browser with the appropriate bookmark. You can follow the links at that web page in the same way as with other browsers.
