As you already know, OpenWebRX has the option of an automatic waterfall color setting, which is activated manually by pressing the right mouse button on the auto-adjust waterfall icon.
When many different bands are used, it is very convenient when auto waterfall color adjustment is activated as soon as the openwebrx interface is loaded.
Therefore, I made this script, which activates this function automatically.
<script>
waterfall_measure_minmax_continuous = true;
waterfallColorsContinuousReset();
waterfallAutoButton.addClass('highlighted');
$('#openwebrx-waterfall-color-min, #openwebrx-waterfall-color-max').prop('disabled', true);
</script>
You can add this script to general openwebrx settings in the admin panel.
Or insert it directly in /usr/lib/python3/dist-packages/htdocs/index.html between <head></head>
And that’s it. When you enter your openwebrx receiver, it will automatically enable auto-adjust waterfall color levels.
