With the exception of Vista, Win 7 and greater improved on the XP successes. IMHO, XP was the first really usable Windows OS and it has had a great run. In addition WPF applications such as SmartSDR for Windows really benefits from a DirectX 11 video adapter with sufficient video RAM. For the 1.0.14 beta release, a vast majority of the issues we are addressing are on XP machines. Win 7 and greater have shown to perform better and have less problems as reported by users creating HelpDesk tickets. Also, I suspect that you may have had XP running for some time now on that PC and over time, "stuff" happens to Windows XP that makes it less stable (in the IT business we called it "OS rot") and the fix was a clean re-install. First, XP will no longer be supported by Microsoft as of April 2014, so that in itself is a major factor in your decision making process.
#Dm780 audio overload upgrade
What I am advocating is that you may want to seriously consider an upgrade to a newer version of Windows for several reasons. Any suggestions would be appreciated as my "waterfall is at a trickle" No sound card or digital interface used in this setup. Could this be my issue? By the way - the IC-7200 is a direct to PC USB connection between radio and PC for control and audio. It appears that XP does not allow one to change the sample rate to 48,000 Hz in Playback Devices. Has anyone seen anything like this? One thing I seem not to be able to do is make the adjustments in the pc's audio devices as described at the end of the DAX video clip. Is there some setting I missed? Is DAX audio incompatible with Win XP? Given there was an issue with DAX and XP to start, might there be a lingering audio issue. Very low audio drops out decoding all together as expected. I've tried different settings of audio levels in SSDR and DAX, without improvement. Therefore I tend to rule out Win XP and HRD. Doing an A/B test between radios, the 7200 provides typically good print as one would expect with PSK on strong and weak signals.
The PC running XP has successfully operated with my IC-7200 and the same HDR DM780 software for 6 months on PSK. What I see is about 50% correct print plus some missing characters on all signals that would normally be readable (very strong, strong and weak signals). Followed the YouTube clip for DAX and have the audio successfully going to DM780, PSK traces appear and when decoded by DM780, some characters print ok and others are wrong characters (read as "poor spelling").
#Dm780 audio overload Patch
I have installed the patch for DAX on XP. The setup is the 6500 connected to SSDR 1.0.24 on my XP PC with DAX and HDR.
However, all received text is about 50% readable (as if I were trying to copy very, very weak signals). I'm attempting to get my 6500 working on PSK.
