    Ok installed sdr uno with a RSPDx on a windows 10 laptop.

    Works perfect..

    But when i installed it on a different windows 10 laptop.. will not rx any signals.. Software runs but NO signals..

    So has to be something different with 2nd computer ??? both are windows 10 lap tops the one that works is a Lenovo other is a Getec

    No clue... Where to start.

    Lots of things to check.
    Does the software list the radio in use?
    Did the driver load correctly?
    You do not SEE any signals on the display as well as not hear them?
    Some sound card problems can disable the radio from working and windows has a very screwed up audio system with various
    settings in different parts of software to go through.
    There is device manager for the actual sound card, then the sound settings, then the audio program the laptop maker put on there and other stuff.
    Some programs will not work if you do not plug in speakers, some need the volume settings all the way up, etc.

    Don't you just LOVE windoze?

    if there are no sig nals on your waterfall, look at the antenna input, and make sure you have selected the antenna that actually has an antenna hooked up to it. It sounds simple, but it does happen

    I know someone has already mentioned making sure you have the correct antenna selected. I've done that more than once. Other things to check are: Make sure RF gain is adjusted properly; Check and make sure any noise reduction adjustments are correctly adjusted. Adjusted incorrectly and it will wipe out any and all signals.
    If you installed the software and you didn't see any signals when immediately PLAYING the software you may need to open a ticket with SDRuno is supposed to work by default after opening and pushing PLAY.

    I've seen issues where my SDRPlay Duo needs to have the USB cable pulled after a reboot to reset the device. I'm using it on Linux though through the SoapySDR interface, so YMMV.

    When I first installed SDRuno and SDRplay on my Dell laptop running Windows 10 it would not run if the laptop went to sleep and then woke up. I would need to reboot, but it took me a while to figure out what was going on. I now have the auto-sleep disabled and no problems. Another frustrating Windows feature is messing with your audio drivers and settings when it "updates".

    Easy fix for the Windows driver update problem.

    Go to your favorite search engine and type in

    - Disable Windows 10 driver updates -

    Follow the instructions.

    There is no good reason to allow Windows to automatically update your drivers once they have been installed. You can do that yourself whenever you need to.
