Apparently there was a problem with version 20180512 of the Red Pitaya SDR Receiver Compatible with HPSDR that was uploaded to the Application Marketplace.  Please uninstall and reinstall 20180305 to fix it.

Thanks for bringing this to our attention Carsten.

There indeed is a problem with the latest version (20180512). I've
already fixed it in the code but it'll take me some time to make a new
release.

As a temporary workaround, I've removed the latest version (20180512)
from the Red Pitaya application market place and reuploaded the previous
one (20180305). To downgrade, the currently installed application should
be uninstalled and then reinstalled.

Best regards,

Pavel

After repairing my QS1R failed (so far), I have now got myself a Red Pitaya.


It has got v0.98 of the image and I have installed the Receiver for HPSDR.


Setting up Skimmer Server with just HermesIntf (tried 17.7.6 and latest version), I only get spots on the lowest band configured. So if I select say 160/80/40, I only get 160m spots and if I do 40/20/15 I get only 40m spots etc.


The same behaviour with CWSLTee. In HDSDR I can receive fine on the lowest band selected in Skimmer Server. On all other bands (the correct frequencies are shown), there is no signal at all. The display goes down to -399dBFS.


If I select fewer bands the network bandwith goes down as expected (seen in Task Manager)


Same behaviour on 2 Windows 10 PCs (one with the latest versions of all software involved, one with Skimmer Server 1.5 and an older CWSLTee that was already on).


Any ideas?
