Quick follow-up to my query of a few days back wrt WIN7 and digital operation. On my computer system (Dell XPS 420, 4 GB core,com0com, VAC, etc.) WIN7 runs the pSDR/F3K base instrumentation just fine. What won't run are the several add-in softwares for digital operations, e.g. DigiPan, MixW, fldigi, multipsk, etc. These all suffer from some sort of specious "audio" noise that appears on the waterfall as random bright streaks separated by 2-4 sedconds and of <1 second duration.

--->Note that these appear whether the digital program is hooked to anything or not. That is, to put it plainly, the problem appears if one is simply trying to run the digital program, and has nothing to do with pSDR or the Flex Radio.

--->Note that these appear in WIN7 *and* in WIN XP running inside of a VM on WIN7.

--->Note that they do *not* appear in VISTA running as a dual-boot OS /on the same machine. This lets Dell off the hook.

/My first guess is that Microsoft has again changed the way the OS handles the audio substructure, or that there is a specific problem in com0com or VAC wrt WIN7. I have written to Nick at MixW to see if he has any suggestions, but have not heard back from him in any substantiative way (merely an acknowledgment of my email).

I hope that some flexers may have also encountered /and solved/ this problem. Please let me know.

P.S. I would like to try AirLink Express by KR1ST but his web site/ http://www.airlinkexpress.org/index.htm/ seems to be dead in the water. Does anyone know how to get a windows copy of this package?
