two slices on CW Skimmer at the same time

I have a 6700 and use it on FT8 with Slicemaster often on several slices at the same time... when using CW Skimmer I open slice A and it works fine DAX shoes both IQ streams correctly but when I launch B slice in Slicemaster by mode CW Skimmer comes up and then immediately disconnects.... Is it not [possible to run two instances of CWSkimmer at the same time on different bands??

Tnx bc

    Hi bc, I assume that you have two panadapters open and a slice open in each. The DAX button on the panadapters need to be on and different (e.g. first panadapter on DAX channel 1, second on 2).

    The DAX channel on each slice should match the corresponding DAX channel on its panadapter.

    If you are using SliceMaster, use the CW Skimmer launch window to turn on the Skimmer for each slice. If DAX is set properly but there is no Skimmer running, use the launcher to turn it off and back on.

    Hopefully, this will help.

    That is exactly what I do.. but when I launch the second CW Skimmer it opens then instantly disconnects... i can close the first and then the second will open but I can not have two open at the same time.. this is version 10.8a Slicemaster

    Oh, I see... I haven't had that problem. You might want to reach out to Don, K1DBO. He really supports SliceMaster well.

    Or try using SDR Bridge. I have had no issue running a slice on each of two different panadapter songs different bands. Each panadapter has to have its own DAX IQ channel assigned. The slice DAX has no effect on CW Skimmer. Make sure both DAX IQ channels are enabled in DAV control panel and sample rate matches setup in Skimmer.

    Thanks for the kind words.

    ...and a minor correction for the record. There's no need for the DAX audio channel to match the DAXIQ channel. The DAX audio channel on the slice doesnt even need to be set at all. All Slice Master needs is for the DAXIQ channel on the panafall to be set and for that DAXIQ channel to enabled in SmartSDR DAX. When set like this Slice Master can launch a CW Skimmer for any or all slices in that panafall. The only restriction for multiple slices on a single panafall is that they all must be "close" to the center of the panafall. The panafall center frequency determines what data gets sent the DAXIQ channel. If you move a slice out of range the associated skimmer wont be able to decode anything until you move it back. This is great for running split from a single panafall.

    Two CW Skimmers should work just fine. You can have as many skimmers as you have slices. Depending on your computer, it might not like it much if you try to run 8 of them, but it does work.

    In your case, Slice Master is launching the second CW Skimmer. CW Skimmer is then crashing. The question of course is why? A quick look at your logs might help me to sort it out.

    Please send an email to the address you see when Slice Master starts up and we'll get started.
