    Cautionary tale from Clint KA7OEI's blog about an Ali Express "SDR TX/RX Switch": https://ka7oei.blogspot.com/2025/02/ali-express-sdr-txrx-switch-design-not.html

  • v1.820

    jksjks

    From the CHANGE_LOG file:

    v1.820 August 18, 2025

      TDoA extension: (thanks UDXF forum)

        Fixed problem with sampling hosts not consistently appearing on result maps.

        Added new checkbox: Show "TDoA map with hosts". This causes the "... with hosts" result map

          to always be shown at the end of a run rather than the default "... no hosts".

       

      Connections to URLs of the form "kiwisdr.local:8073" work again. (thanks nitroengine)

  • Inactivity timer and password prompts while using kiwisdr.local address [fixed in v1.820]

    And... I think I see what's wrong. IPv6 link-local address are not being recognized as valid local addresses due to a very simple bug. I wonder why I never saw this before?

    Anyway, thank you very much! Will be fixed in the next release.

  • Direct access to S Meter and Spectrum data

    Well, now hold on. You should have mentioned your exact application at the beginning.

    Something the Kiwi does do is allow precise GPS timestamping of the audio stream. This is how the TDoA direction finding application is able to work. Now post-processing the audio, extracting the timestamps and synchronizing the audio samples from geographically dispersed Kiwi is not a trivial task. But it is essentially what TDoA does.

    So if your goal is to measure time-of-flight of LF/VLF static crashes (a la Blitzortung.org) then there might be some hope. But it will take some moderately complex programming.
