Overview

SuperSDR

SuperSDR integrates a realtime spectrum waterfall and audio receive from any KiwiSDR around the world, together with a local (or remote) controlled CAT transceiver. There are three main items that may be independently controlled:

  • the KIWI WATERFALL, that may be linked to the CAT radio or to the mouse/keyboard tuning;
  • the KIWI RECEIVER, that may be tuned everywhere on the HF bands;
  • the CAT radio that serves as the main tuning method.

All three may be strictly intelinked, or set up separately depending on the operating convenience:

  • the WF is usually tuned by the VFO on the CAT radio to serve as a panadapter and the KIWI RX may be turned off if not necessary;
  • the KIWI RX may be tuned on a secondary frequency with keyboard and mouse or with the VFO, then the CAT radio is unlinked from the RX and is free to explore other frequencies;
  • the RX and the CAT radio are both active on different frequencies while you can explore the bands moving around the WF window and its span. In the future I plan to support multiple KIWI channels both for the WF and the RX.

SuperSDR in action

Prerequisites:

Install Python 3 along with PYGAME, PYAUDIO, MATPLOTLIB and NUMPY/SCIPY, or whatever it asks when breaking apart upon launch ;) If you use Linux I hope I don't have to tell you how to install librearies and Python components: I presonally use a Arch based distro and pip to keep everything updated.

On Windows:

There is now a preliminary Windows executable thanks to Giovanni Busonera. This version doesn't need any library nor Python environment. The Windows executable will always lag a bit during the development.

I don't personally use Windows, but a beta tester let me know that you can run it there:

  • Install miniconda and the proposed version of Python (3.8)
  • Now open the miniconda powershell to install the packages as below:
    • conda config --add channels conda-forge
    • conda install pyaudio
  • then use pip on a powershell:
    • pip install numpy
    • pip install scipy
    • pip install matplotlib
    • pip install pygame

Use:

SuperSDR tutorial

There is now the possibility to launch the program with no command line options and select the kiwi server at the start or change it at runtime (still buggy, but it mostly works). To use the CAT, at least for now, you have to specify it from the command line.

To launch the program:

./supersdr.py --kiwiserver 192.168.1.82 --kiwiport 8073 -z 9 -f 198 -w password

to just explore your local kiwisdr, or:

./supersdr.py --kiwiserver sibamanna.duckdns.org --kiwiport 8073 -S 192.168.1.89 -P 4532 -z 9 -f 198

to connect to a remote kiwi AND to a local CAT radio for which rigctld is running on the server located at 192.168.1.89.

Just use --help to show all available command line options.

Main key commands during use are shown by pressing H or moving the mouse to the HELP label on the bottom right.

When connected to both a kiwisdr and to a CAT radio any click on the waterfall synchronizes the radio and, vice versa, moving the VFO on the radio, changes the tuning on the waterfall causing the WF window to follow when outside the span.

Have fun!

  • Should auto select the proper modulation for the given band.

    Should auto select the proper modulation for the given band.

    The application should provide an 'AUTO" mode to auto select the modulation, i.e.:

    • "AUTO" mode is selected
    • frequency is 7100, LSB is selected
    • frequency is switched to 14100, mode should switch to USB

    "AUTO" is disabled if the operator manually change the mode.

    New useful features

    Hi, I'm using the SDR with the new features and it looks fantastic. I don't wanna bother you, but I think that some other features could be useful and can increase definitely the donation rate :-). I identified these most important ones (in my opinion):

    • make the filter passband variable
    • show the current frequency of the mouse pointer
    • enabling the mouse wheel for zooming

    Thank you again, Bye Giovanni

    Hello,

    Would it be possible to have the audio mute if the radio connected by CAT is transmitting. I think you might have looked at this as an option some time ago. Thanks

  • Frequency

    Frequency

    Nice piece of software, tracks my K3 and gives me real time waterfall.

    Some minor problems: CW frequency is given as the bfo frequency, not the carrier frequency so my K3 is off by the sidetone. Ok on SSB and AM.

    Ideally software should use defaults on startup, eg kiwisdr.local:8073 and rigctld on localhost:4532

    The connection to dxcluster is superfluous and are better served by other software.

  • v3.11(Feb 18, 2022)

    Hi, big release for a smallish 0.01 version difference! I just added the Logger subsystem so you can log new QSOs interactively and search for old ones. It saves data in a simple and human readable/editable log file: no databases! Even if you have a log with 100K QSOs it will be something like 10MB... The graphical interface has been optimized and several small bugs corrected: now the red/green colors of the MAIN/SUB RX make sense. There is still something to do when CAT is active. The logger dialogs use TKinter, so a new dependence... sorry, it would have been really ugly to implement them in SDL/PYGAME from scratch. I'll convert the KIWI selection dialog too in the near future.

    SLOW/FAST tuning mode is now usable by pressing CONTROL/SHIFT and the arrows. I also lowered the CW pitch to 500Hz, if you don't like it, just change the constant value in the utils python file ;)

    Enjoy!

  • v3.1(Feb 15, 2022)

    Hi, this version should be stable. I fixed bugs regarding:

    • the memory system,
    • the audio recording system,
    • the audio buffer size, and the desyncing over long times due to fractional audio sampling of the kiwis,
    • much improved DXCLUSTER client and spot management/visualization (new colors showing spot age),
    • new command line option to increase window size (1920 goes full screen),
    • deep code cleanup,
    • sub-khz resolution for command line frequency,
    • improved s-meter behavior.
    • added the possibility to disable the DXCLUSTER client without losing the accumulated spots (P shortcut).

    Enjoy!

  • v3.0beta(Jan 31, 2022)

  • v2.1(May 23, 2021)

    Hi! Introducing several new features and bugfixes.

    • The main new feature is dual receive from the same or from two different kiwis. To activate it on the same kiwi, just press Y at runtime, pressing Y again switches A/B VFOs. You can independently change all RX parameters and audio volume. To turn off the second receiver, you may either press M to mute it or press SHIFT-Y. To activate the 2nd RX from a different kiwi, just press Q (to select a different kiwi) and it will be stored in the permanent Kiwi repository saved to disk. Now that your different kiwi is stored with a number, lets's say NUMBER 1, you can activate the 2nd rx by pressing Q, then R1 and ENTER. Now pressing Y will contact the nr. 1 receiver and open it as the 2nd rx;
    • Another cool feature is temporal averaging to detect extremely weak signals (a bit in the spirit of Leif Asbrink's LINRAD): you may increase (G key) or reduce (H) the averaging. Keep in mind that an averaging of 100X produces a frame rate of one hundredth, so it may be useful to monitor the band for an extended time;
    • Colormap fine tuning: up to now the colormap was automatically and dynamically set up. For most applications it was fine, but to really exploit the averaging you can now change the upper (lower) limits by pressing , and . (+ SHIFT respectively). This parameters are visible in the upper left part of the spectrum.
    • DX cluster is now much better integrated and the graphical presentation is much better;
    • Click and drag tuning on the spectrum display, with visual freq shift indicator.

  • v1.1beta(May 1, 2021)

    This release features several new features and bugfixes. The code has been thoroughly refactored following a more object-oriented style even if there is still a lot of work to do. The user can now choose at runtime which operating mode to use: SYNC or not. SYNC means that CAT and KIWI tuning are linked and every change on the real radio or the supersdr interface will change the other. Disabling SYNC frees the CAT VFO from the KIWI RX frequency/mode and the waterfall continues to work as a panadapter for CAT and the KIWI RX will act as a second receiver on a monitor frequency. The two receivers are resyncable to converge again on the same freq. Memories are now implemented as a circular buffer: you press W and store, press R repeatedly and you cycle through them. 10 memories are available, the oldest will be erased if you store more than 10.

    We also feature a new Windows release
