Ah, but since Beta 14 the PowerSDR software has taken my CPU from 5%
usage to 40%usage and it's been staying there since, I keep
downloading from SVN and compiling hoping it will be fixed.
I have run FTP-Wisdom, and it helped, it took it from 95% to 40% but
something is different, some of my lesser CPU's can't run the
software any more without hiccups, they use to have none with Beta 12
and earlier.
I have a Dell GX280 with a 2.4GHz Pentium 4 with 1 Gb of ram, not the
fastest but not the slowest either.
All of the above information is with the panadapter set to AVG and
the display rate set to 8 fps instead of 15 and the S-Meter turned
off. If I turn off the display the CPU usage goes down a little bit
to 30%, before that it would really take a dive when you turned it off.
I have not brought it up before because several others mentioned it,
but I get the feeling that Flex-Radio is not aware of this problem,
because I have not seen a solution.
I wish I could say that it's just peculiar to my main PC but it does
the same on several PC's.

All this talk of motherboards, I would get something with extra gas
in the tank.
The basic SDR DSP and audio run fine on a 533MHz machine. What you
need the extra power for are (1) the graphical display (2) short
buffers / low latency (3) the ability to run arbitrarily many,
arbitrarily complex applications alongside the SDR.
In other words, you need very little CPU to run a receiver tuned to
a single frequency all day long. What the extra power buys you is
being able to do *other* stuff at the same time.
You need even less than that if you're running a half-duplex
application like a PSK-31 program. Where the burps really show up is
in sustaining full-duplex audio.

I fail to see why doing the same thing over and over and getting the
same results every time is insanity: I've almost proved it isn't;
only a few more tests now and I'm sure results will differ this time ...

Yes, it definitely sounds like something is wrong. However that means
that something *is* wrong. It says nothing about what resources are
required when it's running *correctly*.
