Hello Dave, Gary,
similar here - saw WSPR from Gus on the spectrogram
for some time, but couldn't decode until I insterted SpecLab's 400 Hz
bandpass into the audio path. I'm using WSPR 2.0 at 2.0 kHz BFO offset, and
no AGC.
Also did a few WSPR transmit periods
between 23:10 and 23:30 - many thanks to all who reported.

Dave, LF,
Sorry for the late response, only just read my mail (Sat 1330utc).

My WSPR decode performance is
much poorer on 137 kHz than on 500 kHz, although the setup is identical. I
suspect that the strong in-band carriers on 137 are having some
effect.
I have the very same problem & the only way I can get reliable & a
high percent of decodes is to use the 400Hz filter in the JRC NRD-345 Rx.
