[600MRG] Will 630m N.Am. to VK/ZL start late Feb? XIQ, XXM, XJM, XKA SNRs at XCR.

[James Hollander]

The path from XIQ or XXM  to XCR goes about half-wayto VK,ZL.  According to the TABLE, XIQ and XXM currently enjoy comparable10-15dB respective headrooms over the WSPR decode threshold to “spend” on the 2to 4 additional hops for their signals to go the rest of the way beyond Hawaiiover the ocean path to VK/ZL. 

XIQ late last summer at 4 watts enjoyed decodes into both VKand ZL.  My records show no TP decodes for XXM last fall when XXM wasrunning 1 watt. All told, I interpret the dB headrooms now probably same forXIQ and XXM.  

Window times of peaks in 0900-1330Z interval are not tabulated.  Blank regions signify NA.
 
XJM and XKA currently needheadroom, and are mostly decoded at XCR outside the VK/ZL window at this time.
