HSModem want a dedicated output device?

    Hi all, I'm new to this forum. I apologize if this question has already been discussed, I searched the forum but couldn't find any help.

    The question is about HSModem setup: when I try to set my radio's audio input as the output for the HS modem, the software tells me it is not available. The channel is a USB audio device. I receive from a different audio (VAC coming from a SDR# instance) with no issues.

    I have other programs targeting that channel (WSJT-x, MSSTV etc) but they are not active. The device is declared not to accept exclusive access. OS W10.

    Any trick is welcome.

    Hello Pietro,


    the selected output of HSModem needs to be an output device. You can use a soundcard output and connect it with a patchcable to the input of a soundcard but you cannot choose the input of the soundcard as the output of HSmodem.


    Therefore it easier to use a virtual audio cable (in my experience VAC works best).


    Kind regards

    I beg your pardon if I'm bak after a while...

    I receive from SDR# through a virtual cable (VAC) as you suggest. I'm tryng to trasmit via my ft818 via an external audio device. This configuration are working well with FT8, SSTV, KG-STV and fldigi. But HsModem does not allow me to send the output to the radio. Has I to ut a VAC here, too? Why? Or maybe I have to adjust somethisng as bitrate or othere?
