Hi Martin, Markus !

The soundcard has to be set to 48000 S/s at the hardware/driver level, this is vital!

(Windows standard is 44100 "Hz", DO NOT USE THIS FOR WSPR-X !)

prerequisite : close all programs using a soundcard before doing the following (or you will get warnings/errors from win7)

How-to on Win 7 : right click on the speaker-symbol at the taskline, select "recording devices",
select your current device, click on properties, select the "advanced" tab, under "standard format" setting it to "2 channel,16Bit,48000 Hz(DVD-Quality)".
At the volume tab of the input device, I had to set my input to "10" (percent?) to not overload WSPR-X.

click on OK to accept changes.

The dB-level shown at WSPR-X shall not exceed 40 dB (even at strong signals), around 30dB is said to be best. Adjust the input-volume level accordingly.

Set the same "2 channel,16Bit,48000 Hz(DVD-Quality)" to the output port. (maybe it has 24 bits as well, thats ok, too, but 48000 is mandatory)

WSPR-X at Windows 7 does not have a chance to set this settings by itself, as windows just tries to do a samplerate-conversion from 44100 in software, which is horrible for our purposes.

Another hint : please check the above mentioned setting to 48000 after each boot-up of win 7, my win7/64 is changing itself back to 44100 from time to time ! (bad habit)

Using all this settings, WSPR-X does decode very well and sensitive.

Hi Martin,
version r3058 is working fine here. Theissue 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.
Best 73,

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?
