  • Possible TDOA Extension issue

    Should be fixed now.

  • v1.403: colormap improvements, multiple DRM schedule databases

    The new DRM schedule database from drmrx.org is preliminary. Chris and I working on reorganizing the entries.
    DRM tip: while listening to R. Kuwait 15110 I got left-ear-only audio (while using headphones). You can duplicate the left channel audio on the right via the pan control on the audio tab (e.g. set it to "50 R").

    The new "SdrDx" colormap from the project by the same name is worth trying.

    The new aperture auto mode is now the default and will hopefully lead to better looking waterfalls in people's Twitter posts and YouTube videos.

    The "colormap designer" is more of a toy for now. It needs more features to be really useful. Screenshot at the end of this post.

    From the CHANGE_LOG file:
    v1.403  September 17, 2020
        DRM extension:
            Added schedule database selection menu. Includes database from drmrx.org
        
        Waterfall/spectrum/colormap improvements:
            New terminology, colormap "aperture" (what the WF max/min controls really define).
                A colormap spectrum bar now appears above the WF sliders.
                It is similar to the bar that appear on the right of the spectrum display.
                It changes as you adjust WF max/min in manual aperture mode or automatically
                in auto aperture mode (see next). Markers appear at the WF max/min points
                whereas the bar itself covers a fixed -140 to -25 dBm.
    
            Added aperture auto mode to existing manual and one-shot (auto-scale button) modes.
                On the main control panel WF tab there is a new menu "aperture".
                *** Auto mode is the new default, but the choice is saved across page reloads.
                    This is designed to help always keep the waterfall dynamic range optimal
                    for folks who never get around to learning how to use the WF max/min
                    sliders or even the "auto-scale" button.
    
                In auto mode the WF max/min sliders become WF ceil(ceiling)/floor.
                    This is the amount of "headroom" to create above and below the
                    automatically calculated WF max/min values.
    
            Added colormap control extension consisting of two parts:
                1) Aperture auto mode controls.
                    The averaging algorithm/parameter choices are the same as for the
                    waterfall and spectrum averaging (on the WF tab of main control panel).
                    When in auto mode the calculated max/min values are shown, those that are
                    computed plus the selected floor/ceiling headroom.
                    In auto mode the "auto scale" button on the main control panel lights up
                    to remind you that auto mode is in effect.
                    When auto mode averaging is turned off the max/min values are only
                    recalculated when the waterfall zoom, pan or center frequency changes.
    
                2) A "colormap designer" for creating custom colormaps.
                    A work-in-progress. The details of this will probably change.
            
            Added new colormap from the SdrDx project.
            
        Admin interface:
            Disallow public listing unless at least one password-less channel is available.
            Warn about creating URL redirect cycles.
            Display UTC/local time on admin status page.
    
        Use string hashing for faster API command decoding.
        Many other bug fixes. As usual see the Github commit log.
