Roger,

Unfortunately I don't think I can help, as I'm a total novice at= WOLF, so can't really come up with any quick fixes!

All I did was set the centre frequency to match the USB tuning offset - tu= ne low 1kHz to 502.5 and set centre frequency to 1000Hz.

I think pretty much everything else standard.

Looking at my version I see that under "Mode"... I have "Re= ceive Only" ticked, "WOLF 10[symbols/sec] " ---> "N= ormal Speed" ticked.

That's all I've done initially and it worked. Lawrence in China su= ggested I try to calibrate my soundcard, so I followed his suggestion.

I know, as has been discussed before, that WSPR is often touchy about soun= dcard sampling rates and string signals.

Don't know if WOLF is the same.

But at least can adjust for this in the software with WOLF though.

Tune to 197kHz in USB mode. THe Radio 4 carrier should be at 1kHz. If you&= #39;ve chosen a 1kHz centre frequency, on the WOLF Config tab there's= a button marked "Cal" in the receive options area. Press it. It= will work out a correction factor for your soundcard. I think you're= then asked to accept the value offerred... do this and then start again.= See if this fixes things.

As Dave YMC rightly comments - this might be one to try and then forget,= although it seems (of setup correctly) to be quite sensitive.

Cheers,

John
