DAX IQ stream are not working for me on V2.4.9. I get the rest of the Dax process but not IQ to feed Skimmers.  

IT that by design or am I not doing something correctly?  Any thoughts Appreciated.

    I think only DAX and NOT DAXIQ are supported in ssdr v 2.4.9 Smartlink DAX.  Although is not explicit enough in any FLEX writeup. However, most discussions about DAX via smartlink typically pointed to supporting DAX and not DAXIQ.

    The support for DAX smartlink focused on minimizing network traffic and i believe DAXIQ would be quite a network data hog and would consume a lot of bandwidth.

    I have been able to get smartlink DAX to work on FT8 modes. And some rtty copy too

    That’s where I’m leaning as well. Everything else works great Documentation is vague so thought I’d ask Mike

    You are correct -- DAX IQ will not work over SmartLink for now.  Something to keep in mind when/if we do enable it.  DAX IQ takes quite a bit of bandwidth.  48kHz would be 48,000 samples per second * 2 channels * 32 bits per sample = 3Mbps per DAX IQ channel.  For 192kHz, it would be 12Mbps per DAX IQ channel.

    WOW I think you just gave me the answer I was looking for!
    Issue with DAXIQ on PC at client end of remote system. Local PC at remote site works perfect but at my home they done show up. Well just loaded a Windows 10 laptop and DAX IQ works on Smartlink but network shows yellow. It is streaming but dont have CW skimmer to look what is happening or not. Does tax the network so guess not usable but they did load where my two other PC’s they don’t show up at all! Still working it. Possible Window 10 update KB4462919 seems ok but KB 4462933 maybe not! Will back out 2933 and try again,
