and WSPR wins.....

WSPR:
2308 -32 -0.4   0.137450  0 WD2XES FN42 37

JT9-2 (no decode):
2308 0 -31 -0.7 1400.7 -1


Capture attached.  To validate the "shoot-out", had to get SNRs near the 
threshold.  Before doing anything more exotic like artificially 
injecting noise, switched to the south beverage array. We'll see what 
happens with further sessions.

73 - Eric NO3M, WG2XJM
