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 37with 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.
