Hi Joe,
 
during this week, your signal has been = detected=20 here every single night, along with Mike and Spiros.
 
I have been running the "deep=20 search" correlation detector in parallel with the original Opera=20 software. Here's the number of spots=20 received here in five nights since  Sunday:
 
call  =  opds  =20 Opera
       hits  = decodes
 
VO1NA   12    =  =20 1
SV8CS    8      = 4
