Jim,
The thing to check for is the number of sync locks it has , ...
gives a good idea of the path usability.

Subject: LF: Re: WSPR SNR
Dear LF Group,
Still watching G4WGT's WSPR signal here - it is interesting to see how it
copes well with the QSB. Compare the last few decodes:
2006 -30 1.2 0.503599 0 G4WGT IO83 37
2014 -22 1.1 0.503599 0 G4WGT IO83 37
2018 -22 1.0 0.503599 0 G4WGT IO83 37
2024 -27 1.3 0.503599 0 G4WGT IO83 37
2030 -24 1.2 0.503599 0 G4WGT IO83 37
with the WSPR spectrogram attached (it looks similar in Spectrum Lab), and
you can see that although in a significant fraction of each transmission
period the signal has faded to invisibility, decoding has still been
successful.
It is also interesting to see in the WSPRnet database that GM4SLV is
reporting SNR that is consistently several dB better than here at M0BMU,
although he is nearly 3 times as far from G4WGT.
Cheers, Jim Moritz
