[hpsdr] PowerSDR vs Kiss

[Berndt Josef Wulf]

G'day,

The Mercury card arrived today and it was time to play with HPSDR. The current 
system consists of Atlas, Ozy and Mercury. 

I downloaded and installed the current PowerSDR and Kiss versions from the 
OperHPSDR website. Initially nothing was going to work until I also installed 
Microsoft .NET Framework version 1.1 on a Windows XP box.

Eventually both, Kiss and PowerSDR started working. Whilst pushing both 
applications through its paces, I noticed that the signal level indication on 
the S-Meter and panorama display on PowerSDR shows -70dBm without pre-
amplifier switched off and antenna disconnected, whilst Kiss shows a more 
realistic level of about -120dBm.

Not having any experience with either applications, I'm at a loss finding an 
explanation. Perhaps I missed a setting in PowerSDR?

Also, is there a way of listening to the audio on the PC just with USB 
connected? I alway had the impression that data is send via USB, similar to 
the USRP, and data processing was done on the PC. It took me some time to 
realize that I had to plug the head phone into the Mercury PC or alternatively 
use an audio cable connecting it to the PC.

How does this work with Metis?
