    I ve been wondering the same thing. It would be a real service to hams if someone would work on this. Best regards, Michael KD4SGN

        John,

        I've tried two low-cost soundcards purchased on ebay.  The one that works is a no-name black device labelled "7.1 Channel Sound".  It was recommended by another ham on the Raspberry Pi forum.  With that soundcard, fldigi waterfall displays in Raspbian are similar in quality to displays of the same audio source by fldigi running on a conventional laptop.

        I have a higher quality soundcard on order, but it has not arrived yet.

        Best regards,
        Michael
        Michael,
         
        What soundcard were you using? And were you using the distribution with hardware floating point?

        After a lot of experimentation with those Raspian binaries, I have not found fldigi useful for receiving.  I've only been able to achieve sporadic psk-31 decoding.  The more processor-intensive modes don't work at all.  I really didn't expect the more demanding modes to work, but it would be nice to be able to use the Raspberry Pi for psk-31.

        Best regards,

        The Raspian distribution includes precompiled binaries for fldigi, nut I'm not sure if any of the others do.

        Hi,

        has anyone done an optimization fldigi for raspberry pi?
        thanks Beau n9mfk

        John,

        Sorry, I missed your second question in the last email.

        I'm using the most recent update of Raspbian which has hardware floating point.  BTW, the biggest issue with getting fldigi to work at all was not fldigi.  It was solving the problem of voltage drops in the cable and the poly fuses.

        Hi,

        has anyone done an optimization fldigi for raspberry pi?
