SdrDx 2.09 adds the ability to fine-tune the AGC metering to match the sample rate and other varible SDR factors so that the AGC metering is better correlated with the S-meter. DNR metering is now active, but indicates red, when disabled. Auto Noise Floor tracking has been added; this keeps the RF waveform cleanly on the graph even when the noise floor rises significantly. Smooth Noise Floor has been added; this reduces the amplitude of the noise in the RF waveform (does not affect demodulation.) The ability to live-edit the waterfall palette has been added. You can now change colors and adjust the relative distance of one color from another while watching the results on the waterfall. You can save and reload the results, and control which palette is the default waterfall palette. To go along with this, the ranges of the I and C sliders have been extended. An independent high pass filter has been added to complement the low pass filter, and this has been added to the memory system as a memorized setting. The ability to determine the distance of a nearby lightning impulse has been added, along with documentation on how to use the feature. The UI has been changed slightly to accomodate a few new controls.
There have also been significant improvements and additions to the documentation. Some bugs have been squashed, none of them serious.
My sincere thanks to those who helped me test and who took the time to report my errors to me so I could fix them.
