John,
 Seems not all spots made it up to WSPRnet.
 here is what I have :

1904  -14   0.1    0.137430    0   WD2XES        FN42     30    675 				  
		

1908  -14   0.3    0.137430    0   WD2XES        FN42     30    675 				  
		

1912  -14   0.2    0.137430    0   WD2XES        FN42     30    675 				  
		

1932  -14   0.4    0.137430    0   WD2XES        FN42     30    675 				  
		

  
 :32 and :36 made it.
 Care.

All,

Other than the stability issues reported with WSPR-X (no uploads, blank
waterfall, lockups), I'm getting suspicious about its weak-signal
performance. My reports on SNR for Bill's (WH2XRR) signal on WSPR15 are
curiously lower than I usually see when he's running WSPR-2. For that, I
decode with WSPR2 or WSPR4, not WSPR-X. They seem to be off by almost 6
dB, and that's close to the expected WSPR-15 weak-signal advantage.
Something doesn't seem right!

After the current 1830-1845Z segment finishes for WD2XES, I'm going to
switch over to WSPR-2 on 137.430 kHz for the rest of the afternoon, with
a 50% duty cycle.

It might be interesting if some of you could compare what you've been
getting with my WSPR-15 signal with the upcoming WSPR-2 signal.

John, W1TAG/WD2XES
