  • Spur Reduction

    PowernumptyPowernumpty
    This is one reason why I love the Kiwi, take a laptop/tablet/phone out to the feed line and try stuff while watching the waterfall, harder to do with other receivers.
    I ran one channel on a PC set to… (more)

  • Power issues.

    PowernumptyPowernumpty
    The things that may help may be minimising the length of any DC leads and improving or removing mating connectors.
    The Kiwi takes very little power but light wiring or poor connectors could exacerbate… (more)

  • Kiwi for VHF/UHF

    PowernumptyPowernumpty
    Just playing with an Adalm Pluto with third party firmware.
    No band filtering of course and it's sold as a learning tool rather than an SDR but still fun to start (a narrow) OpenWebRX between 70MHz… (more)

  • wifi on BBG (MT7601)

    Easiest route is probably something like the TP-Link nano routers (E.G. Tl-wr802n), powered from 5V.
    It connects to the Kiwi/BB via ethernet cable.
    That set up is good because it offers more placement… (more)

  • Audio queue depth slowly drops to zero, then resets, causing audio underrun - 8 receiver mode

    Are you running external WSPR decode (with a recorder.py etc.) or the WSPR extension? running external decoding would be a better move in this setup I believe.

    The extension is simple but there are benefits to using the external decodes, the detection rate is higher by default.

  • PSU - identify the 34p one

    PowernumptyPowernumpty
    I'm sure there are many older supplies designed when compliance was "a thing", I've got a few that seem pretty good but I'm keen to find resonable current options for those people without decent "… (more)

  • Wide band, vertically interleaved interference

    Eckrot 5G next, 700Mhz, 2.3GHz, 3.5GHz, 26GHz, 60GHz, 100G+ once they get going. I know it shouldn't affect HF but sure as hell it will affect health, industry lobbying to the max.
    I'm sure one of the… (more)

  • USB-C as a KiwiSDR Power Source?

    PowernumptyPowernumpty
    As a bit of follow up on the PSU I mentioned above (Nobsound 25W USB DC5V-24V Adjustable).
    I have found it is potentially dangerous as delivered to me.

    I was going to look how easy it was to disconnect… (more)
