Make sure the Firewire driver is in safemode1 and the sampling rate is exactly the same as what is configured in PowerSDR
Use these parameters: 96K with 1024 buffers 192K with 2048 buffers Also, check the duration of the DPCs. I suspect you are having something responsible for long ones. One other thing to check is to make sure the Firewire networking is turned off and if you are using a motherboard Firewire host bus controller, consider one that connects to the PCI/PCIe bus. -Tim -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of George Rebong Sent: Sunday, October 05, 2008 12:29 PM To: flexradio@flex-radio.biz Subject: [Flexradio] Applications/Programs .My FLEX5000A will stall after 3 or less minutes. I have to click on the start button to get it running again and will quit again. I don't have any other applications running in the back ground. I check it to the TASK Manager to make sure. I have a Vista Premium - Intel Quad Core with 4 Gig memory. I need to know if there other ways to check / or close the applications on Windows START-up. 73 George KE6TE -- George Rebong KE6TE _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/ _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/
