I'm still rooting for official company (and software) support for the Audiophile 192 running at its 80kHz sampling bandwidth here :)... (I *really* want that 160kHz panadapter). As I recall the two 192's showed up separately in both the M-Audio control panel and in PowerSDR such that you could select the one you wanted to use. > If anyone installs two D44 cards and has two SDRs going, > please post the > results. I dont have a spare card right now to try. I did have two 192's installed at one point but never actually tried running two sessions of PowerSDR with them. May just have to try that this weekend. > PS - Duane, have you benched the AMD processor with > PowerSDR against an > Intel P4 3.4 650 processor or similar? Is your AMD the > dual core unit?

(Hyperthread > X2) I have not done any benchmarking against anything else. It is a plain Jane AMD Athlon XP 3000+ and is not dual core. This AMD based machine has 1MB of RAM and is definitely not near the top for performance heap by today's standards, - even when I bought it wasn't. I always buy based on the best horsepower/$ point on the pricing curve. Even so in recent (last 8 month or so) versions of PowerSDR it has only been running at <15% CPU time total (driving it with VNC only bumps up the CPU usage a few percentage points. The RAM usage is very modest as well. Based on these observations and I my gut instinct tells me that running two sessions of PowerSDR the machine will not be CPU or RAM limited. Until of course that 160 kHz panadapter version comes out :)... If I don't have the horsepower at that point then I'll just buy more CPU horsepower ;) - after all it's the least expensive part of this radio.
