Hi Tim, Thanks, here are my details... I just wanted to get the ball rolling on a known issue across many SVN's, Firmware & release dating back to pre-pal. We would like to re-visit the issue please.
What version of PowerSDR are you referring to? SVN3501 What Hardware platform are you using? Flex5000A What Firewire driver are you using? (assuming a FLEX-x000) 3.5.0.7171 What firmware are you using? (assuming a FLEX-x000) 2.0.0.3 This is my current status, Les will contact with his details. 73' James --- On Thu, 21/1/10, Tim Ellison <[email protected]> wrote: From: Tim Ellison <[email protected]> Subject: RE: [FlexEdge] ARQ mode Problems Winmor / RFSM etc To: "James Nelson" <[email protected]>, "flexedge" <[email protected]> Cc: "[email protected]" <[email protected]> Received: Thursday, 21 January, 2010, 5:43 PM What version of PowerSDR are you referring to?

Usually the connects are 1st time however during the connection at a random time the ack frames become shortened or truncated hence the data frames are damaged and the connection is lost. What we have found using "hit and miss" experimentation is by restarting the Psdr console "off then on" for one second or more during the symptom described above, the synchronization for the PTT and Audio becomes re-aligned and consequently they renegotiate and the connection is saved. Should the power "off and on" remedy not be actioned completion of the transfer cannot be processed resulting in both stations simply calling it quits. Observations would indicate an audio truncation with the PTT timing. Having a VOX selection on the VAC in Digi U/L mode may create a workaround but a solution to the underlying PTT & Audio alignment problem would place our SDR's "up there" with the real time radios thwarting the SDR latency critics. With the help of Les Keppie VK2DSG we have been trying to solve the ARQ mystery. Any help here Gentlemen is very much appreciated. 73' James. VK2JN. &.
