I think you'll find that the FW card takes fewer resources than a USB card, at least that's what I've found as a general rule. On my system anyway, the PCI sound cards take the least resources, followed by FW, followed by USB. The same is generally true of serial ports. If you have a desktop PC, always lean towards PCI interfaces rather than USB if you have the slots to do so.

FWIW, I have 6 sound cards installed on a 2.8GHz P4 without problems, but the USB cards add about 50% to the CPU load when they're running.

Hi Lance,

Hmmm... I don't think so.  The computer has a 2.3 GHz Core2 Duo processor and 2 GB of RAM.  As I said, but not clearly enough, I gave up on the LP-Pan (for now anyway) so it wasn't running.  The only thing running was whichever RTTY/log software and Firefox, which I use for looking at Internet spots.  Since in some of these contests I was in an unassisted category, even that wasn't always open.

Regards,

Wes
