WSPR 28 MHz VK7JJ map

ZL4DC en VK2JMR last days also seen in evening over S-America long-path  so 20.000 km or more?  The daylight path for 28MHz moves with Sunlight from N-E via South to West in evening.  The propagation ends  to S.A. and  Caribbean  N.A. Florida or even when the propagation is real good  to N-E USA . And rarely ZL or VK3 over long path it happened only 2 times in many months while in the morning almost daily VK1234567  seen in Wspr mode. Obvious  the great circle  DX line to ZL/VK  is much longer over long-path S-W  then "short-path" over  North-EAST in the morning The WSPR.org and other sites can or do not reckon  this . The simple calculation is 40.000 - 16500 = 23500km ...  2120 -21 0.7 28.126124 0 VK2JMR QF68 40 16396 should be 20.000km +
