Hello Dave, Gary,
 
similar here - saw WSPR from Gus on= the spectrogram=20 for some time, but couldn't decode until I insterted SpecLab's 40= 0 Hz=20 bandpass into the audio path. I'm using WSPR 2.0 at 2.0 kHz BFO= offset, and=20 no AGC.
 
Also did a few WSPR transmi= t periods=20 between 23:10 and 23:30 - many thanks to all who reported.=
