[hpsdr] Fwd: Re: Mercury v2.4 -- still distorted audio

[George]

I initially got my Mercury working reasonably well with PowerSDR in 
Windows 2000 on an ASUS A7N8X-based pc with a 1150MHz AMD Athlon.

Shut down unnecessary services, disable anti-virus scanning and fiddle with
the video and priority settings.  I found that I could get a usable panadapter
display by reducing the frame rate and by turning on averaging.  This was with 
the original v1 firmware.

Realtime priority actually worked worse than setting the process above normal.

There were also some suggestions earlier about changing the audio buffer 
settings.

Hi,

I have a stone age desktop PC:
1.58 Ghz AMD Sempron 2300+
768 MB of RAM @ FSB 166Mhz

Running PowerSDR as a real time priority process @ 192Khz helped me a lot.
No distortion, even no glitch.
PowerSDR process CPU % : 30 - 55 (pumps routinely up and down)

I have not yet tested it on my laptop which is 1.66 Ghz Intel Core Duo with
1 GB RAM by Hewlett-Packard.
