Hi Everyone, When using FLdigi/FLarq on the Flex1500 Psdr Ver 2.2.3 on either XPx86 or Win7x64 a phenomena of early audio truncation occurs with the PTT being released too early OR the audio arriving too late depending on how you want to interpret the culprit. This presents a problem with fast ARQ such as "MT63" as the "<EOT>" frame marker becomes incomplete/damaged therefor a connect ack is not possible. Another indication/symptom of this problem shows up in the FLdigi CW Ident at approx 20 wpm or faster so in my case the call sign becomes VK2JT in place of VK2JN or another example VK2ACL becomes VK2ACA.
Thinking about latency general in recent time ARQ modes such as pactor & RMS Express(Winlink 2000), these problems through settings have been mostly worked out. In this case could it be the XML file file requires an update somewhere to counter this ? I see the Author of the XML file is our always at the helm Tim Ellison. A good 10 hours between 2 of us has been spent changing buffer sizes & settings in many areas of both Psdr, FLdigi and VAC to no avail. Another interesting aspect is there have been some occasions (that have been rare) that the truncation has not been evident that makes this even more puzzling. This issue does not appear evident on testing with the 5K Would really like some ideas on this baffling little nasty. 73' James VK2JN _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
