K1SIX 50MHZ TRANSATLANTIC Es PROPAGATION ARCHIVES

    The information below focuses on multi-hop (at least TWO or more hops) instances of 50 MHz Es across the paths of interest shown in the table,  during Northern Hemisphere peak Summer Es season: May thru August.  Note that the peak Es season for the Southern Hemisphere also occurs during their Summer months, offset from the Northern Hemisphere by exactly six months.  Both hemispheres experience a minor, short lived peak during their Winter when multi-hop propagation is possible but relatively rare.  

To research summary archive files of K1SIX Summer transatlantic Es results for those years earlier than the link below,  click on the ARCHIVE FILES LINK below and look for files that contain xatlYYYY.htm (where YYYY is the year of interest) and simply click on them.  Always use the filename that contains the .htm extension if one is available.
