Larry.  Well, the data set is limited so we are at the initial observation

decodes were farther into early morning pre-dawn hours---more like the first 
attempt on Sunday into Monday...

Somewhat fewer spots but the trend of multiple W7IUV captures over the 
3200km path seems to be continuing....

WH2XXP signals peaked in the audio range (-11 at 0856 best of overnight 
session)  just before the first W7IUV decode....
