  • v1.390: cross compilation, SAM demodulators

    From the "I'm not working on it except when it interests me" department:
    v1.390  April 23, 2020
        Performance improvements:
            Suggested by @howardsu on Kiwi forum: remove -DDEBUG so assert()'s are not evaluated.
            	Added new "make debug" target to revert to compiling with -DDEBUG defined.
    
            Christoph's cross-compilation changes: added "make xc" target that allows cross-compiling on
                development host. Alternative to slow compiles on Beagle during development.
                See file CROSS_COMPILE for complete details.
        
        Added synchronous AM (SAM) demodulators from Warren Pratt's wdsp package via the
            Teensy-ConvolutionSDR implementation: github.com/DD4WH/Teensy-ConvolutionSDR
            See the Kiwi operation manual for more information: kiwisdr.com/quickstart/index.html#id-faq-sam
            Synchronous AM modes: SAM, SAL, SAU, SAS
        
        User interface changes:
            Use keyboard shortcut 'A' to toggle the SAM modes (sorry, 's' and 'S' were taken).
                As always type 'h' or '?' to see the list of all keyboard shortcuts.
            Bugfix: Adjusting the passband via a "/width" or "/low,high" entry in the
                frequency box is now "sticky" i.e. remembered when returning to the mode.
                Just like when changing the passband via the 'p' and 'P' keyboard shortcuts.
                Restore as usual by shift-clicking on the mode button.
    
    I'm interested in feedback about the SAM demods from the BCB DX crowd. But remember that this code is just lifted from wdsp and I don't know much about it. There are some tunable PLL parameters that could potentially be optimized. Please read the Kiwi operation manual for full details: kiwisdr.com/quickstart/index.html#id-faq-sam

  • Rounded Frequency Set

    Found it. Only happens on Kiwis with ITU region set to 2! (Americas) Has to do with the recently added code to force 1 kHz stepping in the 75/80m ham/BCB overlap segment for region 2 (change made in response to a user request) :/ Will be fixed in the next release.

  • suggestion: add 25 MHz to list of time stations

    I didn't realize they were back on 25. Interesting.

    For historical reasons the content of the "select band" menu (and the band bars above the dx labels) is driven by the javascript file in /root/kiwi.config/config.js This file is created if missing (e.g. on the first software installation) but not touched after in case the Kiwi admin makes any modifications. So I will add 25 MHz to the template file. But for existing Kiwis the file will have to be edited by hand to make the change. Just duplicate the line for 20 MHz and edit to be 25 MHz.

    config.js existed before there even was an admin interface. That's how far back it goes. At some point the correct thing to do would be the read the (potentially customized) file and integrate it into the existing admin interface.

    If you have an account on qrz.com he seems to have an email address there.

  • Request for simple feature: tuning lock [fixed in v1.388]

    Funny story about that. I took my old Mac laptop to the Apple store for a battery change. And while there remarked that I probably needed a new trackpad since sometimes when I single-tapped the double-tap action occurred. The "Apple genius" smiled and showed me about the "secondary-click by single-tapping in the trackpad lower right corner" option. Sure enough, I had loaned my laptop to my son and he had changed the setting. :/

  • rx.kiwisdr.com now has a search field

    For what it's worth, rx.kiwisdr.com (aka kiwisdr.com/public) now has a search field where you can search/filter entries from the list.
    Same thing as sdr.hu has (and the last reason I was using sdr.hu). Matches are case-insensitive. Clear the search field to restore all entries.

    Good for things like searching for Kiwi's on a particular release ("v1.389") or with a particular feature ("drm", "20 kHz", "gps") or location.
