    Hi Bent,

    I assume you are looking for IQ data, right? At the bottom of the DAX panel, you can set the sample rate (max of 96000). I don't know how to set the width, but you could experiment with the panadapter width and see if that influences the IQ data.

    HI Len

    No I was looking for the bandwidth of the DAX audio and also the sampling rate ??? not the IQ streams.

    Trying to use my setup (Flex 6600 + transverters) with satellite's telemetries.

    How could I expand the width of the audio DAX? It's always about 5.500 on the hs-soundmodem waterfall

    Thanks and 73

    The DAX audio stream is the same as the receiver slice audio stream. You can set your audio bandwidth in SmartSDR.

    Hi Mike:

    Even with 24kHz bandwith (DFM mode) when I send the audio to hs-soundmodem software, I only have a 5,5 kHz audio bandwith, not enough for 9k6 satellites.



    What could be the reason?

    If you have not already, you may wish to open a support ticket so they can pass it on to engineering.
