Anything under 1000 us is good. 1500 us and above *may* give you problems. If you get them, set the SafeMode in the Firewire driver to a higher value.

While setting up and testing a new system here, I did a search of the Flex Knowledge Center to see what typical DPC Latency Checker maximum values are. I was unable to locate any ranges of values to use as a reference. What values are other seeing and not experiencing detectable dropouts? (I don't mean for this to be a loaded question, but I am interested in the values others are seeing and the relationship to impact on observable dropouts or glitches.) My maximum is an occasional 395 usecs with no observable dropouts. Intel Core 2 Quad Q8200 Windows 7 (64 bit) Both RX1 and RX2 on. Peak CPU usuage about 15%. Sample Rate: 192000 Buffer Size: 2048. CW sending seems very smooth at 30 WPM using Flex 5000 key input. 73, Bill Bordy NJ1H _______________________________________________ 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://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/ Message delivered to telli...@itsco.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://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/ Message delivered to arch...@mail-archive.com
