The animated coverage map (created with ACE-HF Pro ( http://hfradio.org/ace-hf )) that reveals the footprint of the JT65A digital signal on 20 meters (14.076 MHz Upper Side Band), during the month of June, during the best 70% of the month, during 2011. This is based on an average of 40 sunspots, or an average of a 10.7-cm solar radio flux reading of 94. This assumes quiet to active geomagnetic conditions, during 70% of the month.
In real-world conditions, this prediction has held true, as I have worked most of the world regions during June, 2011, using JT65A. The BLUE area is the area where my JT65A signal can be heard. This has been shown true by the PSKReporter maps where stations have reported hearing my station (NW7US).
