Good evening everyone, I agree with what Jerry wrote, the WSPR propagation does not determine the openings in SSB,
WSPR allows a typical signal of 30db below the noise to be confirmed depending upon the decode engine used.
1 watt of WSPR = 1000 watts of SSB for a typical S1 signal of SSB.
If you get a decode of -30db on WSPR then you need 1000 watts of SSB to make the trip with
an S1 signal.
WSPR reveals a path, but it doesn't guarantee that some some one on SSB is listening, or
has 1kw ERP to make the trip.
Whence the disparity of WSPR reports vs actual SSB QSO's.
