RE: [linrad] Took the bait.
Mine is a non-MMX Pentium. I just happened to have
an old computer sitting idle, and I thought I'd try
to get some use out of it. It sounds like I'd be
better off turning it into a multi-op contest
logging computer. I have this nasty habit of only
upgrading my hardware once every 4-5 years. It saves
money, but the down-side is that they always find a
way to make all of the hardware incompatible. I
usually wind up having to buy a whole new machine
(even the case).
My normal workstation (this one) is a P-II/400, and
it works fine for most apps, but it won't be a top
performer for Linrad either. My XYL (N6QBD) has an
identical machine. I guess I should see if our ATX
cases can handle the power/cooling requirements for
some new P4 or Athlon motherboards.
Of course, we all know that someday you'll make Linrad
capable of running on a Beowulf cluster so we can stack
up our old CPUs, digitize the whole band, and make that
noise blanker work REALLY well ;-)

If you want to run the Delta 44 at 96 kHz sampling 2 radio
channels in I/Q mode for 96 kHz bandwidth (4 audio channels)
you will need a Pentium III at 600 MHz or equivalent.
With a Pentium MMX at 200 MHz you can process something
like 2 x 20 kHz bandwidth but if it is an old Pentium without
MMX, the cpu speed will limit your bandwidth to 2 x 10kHz or so.
