OK, got it.

Indeed, it does appear that way. In fact I ran a 'top' command in the 
other virtual console and the CPU ran up to 99.9% on linrad processing.. 
Not much swapping going on though. Here is one of lines from top:

PID  User   PR  NI  VIRT   RES   SHR  S  %CPU  %MEM Time+   Command
4466 root   25   0  37328  1584  924  R  99.9  0.3  0:45.77 linrad

The above top output was running no second FFT, 200 Hz BW on first FFT, 
0 second storage time on first FFT, and 9 seconds storage time on 
output. The sampling rate was set to 8000 Hz on both first FFT and 
output. I performed the test with both AFC and no AFC...

Mouse appears to work fine with mousetest after I set the device to 
/dev/psaux...

When I perform the sound card test I get a vary low utilization on the 
FFT processing. Why is the main screen eating all the CPU time up?

Thanks,

Brian
