    The reason that radios have an IQ output is is so easy. Many of the answering comments have clearly stated what needs to be done.

    It's easy to do, even if you don't understand it. But you have to follow directions.

    Can you make a pig tail? A pig tail is a plug with a length of cable correctly connected to it.
    For your IQ radio connector.

    On the other end(this end will plug into your audio to usb adapter) needs to be correctly connected to a stereo connector. Can you solder?

    So, IQ cable connected to radio......other end connected to usb adapter.......adapter to computer.

    Now for the software. Normally, the software will default to your computer sound card for the signal source.........that the software uses. your case you do not want that.......because your sound card does not have a stereo in. have to change the software the usb adapter, instead of the internal sound card. The sdr software has to be able to see that adapter.

    Does ANY of what I said, make any sense to you?

    ".you have to change the software the usb adapter'

    i have and used some sdr devices,sdrduo, and am used to using their usb input.

    Do you have another computer, that has a stereo mic input or a stereo line input? It would be a lot easier, especially when doing this for the first time.

    What happens when you make the "IQ from Sound Card" selection in SDRSharp using stereo line input (or two mics)?

    then it was suggested that i d l ver 4.8.
    i got lost following instructions.
    right now im uninstalling all of sdrsharp.
    might start over later.

    downloaded fresh sdrsharp, dozens of files.
    ran sdrsharp. it asks do you want to download 4.8 (net framework) and install.?
    i get a screen full of stuff? but nothing happens.
    if i run sdsharp it repeats asking for 4.8 version...
    its like it never installed...?
