I purchased my Flex 5000A on June 1, 2009. I am running an Emachines PC I bought at Walmart in June of 2008. I am running XP Home Edition. I am running powerSDR 1.18.2.

This is what I did to make things run nicely.

1) Turned off TCP/IP for the firewire card.
2) Disabled windows search indexing.
3) Set powerSDR priority to "Above Normal".

I have been running with this setup now for almost 2 months. I can run outlook express and firefox with no problems at all. My PC is a 2 ghz PC with 1 GB of RAM. It is not dual core. I find my CPU usage runs at 20 to 30 percent. This is working great.

Hi Bob;
Thanks for the info, well you are doing better than me, do you use the hard
wire key board or Blue Tooth , any firewire drives ?

Turn off bluetooth! Don't use it! It drives up DPCs. Also, do not
share the Firewire with anything. The only thing on the Firewire
should be the Flex radio.

I keep harping on this topic but it is true. If you want your machine
to be dead-nuts reliable when running PowerSDR and the other
supporting applications ...

YOU MUST NOT RUN ANYTHING ELSE

PERIOD!!

No anti-virus. No email. No browser. No backup software. No automatic
this or that. Since I have a hardware firewall in my router I don't
even run the firewall in Windows. I don't do QoS queueing, no IPSEC,
no encryption services, nothing. I even disable the Microsoft Network
(NetBIOS over TCP). I want the OS to do only a few things:

1. basic file system;
2. memory management;
3. task scheduling;
4. interprocess communications;
5. the absolute minimum of window management.

Until we have a good way to share functionality across the network I
don't even want to run a TCP/IP connection!
