  • v1.707

    jksjks

    The new git "rebase" I'm working on reduces the size of the Kiwi repo by about 90% to 55 MB. So that should fix this problem.

    Bump. You know, for the incoming shit-storm.

    v1.689 (and later) has countermeasures against the "botnet".

    v1.690 (and later) is necessary for your Kiwi to resume using the proxy service.

    These updates will happen automatically overnight (local time) unless you've disabled automatic updates. You can manually update by going to the admin page "update" tab and clicking "build now" and waiting 30 minutes or so for the build to complete. Your Kiwi will restart when the build is complete.

    Don't start multiple threads about the botnet topic. They will be deleted.

    The proxy service has been disabled because the money (for which I am not compensated) is now flying out of my back pocket:

    I will try and develop a fix in the code to better identify and remove these connections.

    Update: The proxy service has been re-enabled if you're running v1.690 or later.

    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)

  • About Python KiwiClient [Kiwi API question]

    jksjks

    The Kiwi protocol requires the client to send "keep alive" messages at least once every 60 seconds. Otherwise it is assumed the client (Javascript in the browser usually) isn't really running even if the web socket connection is still open for some reason. This had to be done in order to prevent connections from remaining open for long periods of time even through no one was really there. If no keep alive is received the connection is closed.

    I don't know if it helps, but I was able to make web socket connections and send Kiwi commands and receive Kiwi sound and waterfall binary data using a program called websocat (web socket concatenate). See: https://github.com/vi/websocat There are binaries available for Windows, Linux and Mac and I was able to run the Mac one without problems.

    So, to connect to a Kiwi and get sound data do something like this from the Mac command line:

    cat snd.ws.txt | websocat_mac -n ws://my_kiwi:8073/12345678/SND

    Where my_kiwi is the name of the Kiwi and the file snd.ws.txt contains these commands to send to the Kiwi:

    SET auth t=kiwi p=

    SET AR OK in=12000 out=44100

    SET squelch=0 max=0

    SET genattn=0

    SET gen=0 mix=-1

    SET ident_user=kiwirecorder.py

    SET mod=am low_cut=-5000 high_cut=5000 freq=7550.000

    SET agc=1 hang=0 thresh=-100 slope=6 decay=1000 manGain=50

    SET keepalive

    12345678 is a number and needs to be unique for each connection (hence a timestamp in msec). The websocat -n argument keeps the connection to the Kiwi open after all the commands in the file are sent. But note the connection will still close because additional SET keepalive commands are not being periodically sent.

    What you will receive from the Kiwi will be a combination of messages and data looking something like this:

    MSG client_public_ip=[your public ip address as seen by the Kiwi]

    MSG rx_chans=4

    MSG chan_no_pwd=0

    MSG chan_no_pwd_true=0

    MSG is_local=0,1

    MSG max_camp=4

    MSG badp=0

    MSG version_maj=1 version_min=447

    MSG load_cfg= (large amount of configuration data omitted)

    MSG center_freq=15000000 bandwidth=30000000 adc_clk_nom=66666600

    MSG audio_init=1 audio_rate=12000 sample_rate=12001.062106

    MSG stats_cb={"ct":4633,"ce":0,"cf":1000,"cc":0,"cu":[51],"cs":[49],"ci":[0],"ac":0,"wc":0,"fc":0,"ah":0,"as":0,"sr":12001.062106,"ga":0,"gt":0,"gg":0,"gf":0,"gc":66.665900,"go":0,"gr":"RF82ci","ad":0,"au":0,"ae":0,"ar":0,"an":4,"an2":32,"ap":[0,7439,0,0],"ai":[0,2121,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],"sa":9,"sh":9,"tu":"04:04","tl":"17:04","ti":"NZDT","tn":"Pacific%5c%2fAuckland"}

    SND [binary sound data]

    SND [binary sound data]

    ...

    You can do something similar for the waterfall with the command line:

    cat wf.ws.txt | websocat_mac -n ws://my_kiwi:8073/12345678/W/F

    And the wf.ws.txt file:

    SET auth t=kiwi p=

    SET zoom=0 cf=7550.000000

    SET maxdb=-10 mindb=-110

    SET wf_comp=0

    SET wf_speed=1

    SET ident_user=kiwirecorder.py

    SET keepalive

    And you'll receive the waterfall data:

    MSG rx_chans=4

    MSG chan_no_pwd=0

    MSG chan_no_pwd_true=0

    MSG max_camp=4

    MSG badp=0

    MSG version_maj=1 version_min=447

    MSG center_freq=15000000 bandwidth=30000000 adc_clk_nom=66666600

    MSG kiwi_up=1 rx_chan=0

    MSG extint_list_json=%5b%22colormap%22,%22cw_decoder%22,%22devl%22,%22DRM%22,%22fax%22,%22FFT%22,%22fsk%22,%22IBP_scan%22,%22iframe%22,%22iq_display%22,%22loran_c%22,%22navtex%22,%22noise_blank%22,%22noise_filter%22,%22sig_gen%22,%22S_meter%22,%22SSTV%22,%22TDoA%22,%22timecode%22,%22wspr%22%5d

    MSG wf_fft_size=1024 wf_fps=23 wf_fps_max=23 zoom_max=14 rx_chans=4 wf_chans=4 wf_chans_real=4 wf_setup

    MSG zoom=0 start=0

    MSG wf_fps=1

    MSG request_dx_update

    W/F [binary waterfall data]

    W/F [binary waterfall data]

    ...

    This discussion is not complete because we need to talk about the parameters for the various SET commands and also the content of the returned binary data. These details are all handled by the kiwiclient / kiwirecorder Python code and that's why you should really try and make an effort to understand it.

      With Mongoose 7.14 support older non ws format web socket URLs so 3rd party applications

        continue to work, e.g. KiwiKonnect. (thanks Chris, Black Cat Systems)

       

      Fixed Javascript syntax error in waterfall extension. (thanks Pierre)

  • Help needed: fixing the "connections from 127.0.0.1" problem [fixed in v1.816]

    jksjks

    Yep, bug in the Mongoose web server we use. Fixed by switching to an updated version. I had been planning this switch for a long time (it's needed for wide band mode), but delayed because it's a major change. Now there is a good reason to finally make the switch..

  • Wideband IQ streaming mode for local processing? [better late than never!]

    jksjks

    Technically it violates the entire spirit of the Kiwi ethos. Why would you spend money on a Kiwi as an IQ generator to drive SDR software on a PC when there are better alternatives for that kind of setup?

    But having the option is another point of flexibility/experimentation with the Kiwi I suppose. Anyway, it will all make a lot more sense here within the next 6-12 months or so. Maybe sooner.
