Scott,
     OOPS! I picked up Gerard in the thread. However, my response of 
just a few minutes ago is correct. In your case I should have added that 
you need to set the signal I/O device to the sound card you use for the 
spectrum display. This way you get more than just the 3 KHz bandwidth 
you are using and you can use narrow filtering for listening without 
effecting what skimmer is doing. I hope this is all clear.
