I have been studing dpc latency and it is really extrange.
Normally it is around 100 to 200, but suddenly (after some time) it goes to
6000 and powersdr stops comunication with the flex5000.
Sometimes it happens in 10 minutes and other times in a lot of hours.
It is very extrange.

I am using a Macbook on my Flex3K when I get away fro m the shack and
a MacMini on my Flex5K in the shack. I used to use a Dell on the 5K
but it was slow and would lock up.
I am very Happy with the Mac's.

I'm using an older HP Pavilion laptop with an AMD Athlon X64

It works fine, even the built-in firewire.

The only laptop that I've had flawless performance from is the
Macintosh MacBook Pro running bootcamp and XP. Follow the article
carefully in the Flex KB to configure.

of I/O
and processor performance. Occasionally you will run into a
laptop
that works just fine. Other times you can get a laptop that
has the
best specs in the world and is touted to be a "multi media" high
performance machine and it just plain stinks up the place when
running PowerSDR. I have one of the later machines from Dell.

have
found that loading the OS myself eliminates any of the integrator
installed "fluff" programs that they include for usability or
support and those get in the way of a laptop being able to reach
it's highest performance potential. I know Neal (K3NC) is looking
into a laptop optimized for PowerSDR, but due to low demand
and high
cost may not be offering it as a product.
