Phil, I experience the same distortion problem on occasion with my F5K+Rx2+ATU+V/U and PSDR v2.0.22. The problem has occurred on all bands and all modes. Clicking the start/stop button always corrects it.
I run LatencyMon on a regular basis and it has never indicated a problem when the distortion occurs. Highest DPC is usually between 177 and 210 us, highest ISR is usually between 65 and 72 us. My computer is a Dell Studio XPS 9000 with i7 CPU and 8 GB ram, running 64 bit Win7. CPU usage is between 7% and 20% depending on what other programs are running. I do not recall the distortion occurring prior to PSDR v2.0. The distortion issue is annoying but since it is easily corrected, I have not mentioned it previously, although it is nice to know that someone else has experienced the same condition. 73, John N8WNA -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Phil Theis Sent: Monday, July 18, 2011 8:40 PM To: Neal Campbell Cc: [email protected] Subject: Re: [FlexEdge] distortion Sounds like a good plan, but the program says it only works on vista and above.
