From Ken WØCZ ...
You might want to add this information to our RRRA web site so people that are using Windows 7 can work PSK31.
I could tune in a PSK31 signal using either MixW or Digipan but it would go away after just a few letters both on the screen and the water fall.
I found the following procedure fixed the problem.
Right click the speakers ICON
Left Click Recording Devices
Left click Communications
Left Click Do Nothing
Left Click Apply
Left Click OK
There are also screens to adjust the gain and select input jacks if needed under Recording Devices.
Now PSK31 works well again but it was disappointing yesterday when I tried to show a new ham PSK31 and I could not make it work.
Hope this hint helps others.
