Hi Martin,
version r3058 is working fine
here. The issue could perhaps be related to
samplerate deviation. WSPR v2.11 sets up the soundcard at 48000
samples/second whereas WSPR-X is asking for 12000 s/s. Usually the ratio between
the delivered samplerates is an accurate factor of four, but it depends on the
soundcard driver. More than half a percent error will upset the symbol
timing enough to render decoding impossible. You could check it by
injecting a known audio tone and looking at the frequency in the wspr-x
spectrogram.

I've tried and tried to get WSPR-X V0.8 r3058 to decode
- I'm trying
now, on 474.2kHz.
Good strong signals on the waterfall,
computer time synched using
Dimension 4, but absolutely no joy at
decoding.
Is there a secret to this - the older WSPR 2.0 works
fine.
Or is there a later version that actually
works?
