Andy,
In my case, the CPU usage jumps to about 10% with the SDR
function running; that's about 2 1/2 times what Multipsk
uses when running without SDR.

Well, you can run the SDR part of Multipsk (just press SDR
I/Q Direct button in the configuration area, then press
RX/TX to return to the main screen. Then you will see the
SDR waterfall open up. The problem is that without an SDR,
you will only get up to khz of signal, same as the regular
waterfall. Som other than testing CPU load, it defeats the
purpose.
I am guessing you are correct about the dual versus single
core. I may try to minimize the other items that my PC
boots at start up , but they aree not listed by the Task
Manager as taking much CPU.

Andy,
Thanks for posting your CPU test results with Multipsk.
Patrick mentioned that he doesn't think RAM is important in
this case and adding more than the minimum memory
requirement wouldn't change anything; I guess that leaves
the processor.
It just seems odd that there would be a large disparity
in CPU usage since both processors run similar clock speeds
(yours is actually faster). My Dell has a Pentium dual core
E2200 and I'm wondering if the difference is due to the dual
vs. single core?

Would it be possible for me to run the SDR feature
without actually having and SDR rig attached? If so, how can
I activate it?
