ExpertSDR2 SOFTWARE DESCRIPTION
Clipping is a form of waveform distortion that occurs when the output Voltage exceeds
Threshold. Visually (on oscilloscope) it looks like altered signal peaks, you can hear it as
splutters and cracks. Clipper reduces signals peak-factor and increases overall power, but
distorts the signal.
Paramet ers:
Threshold – if the signal exceeds this level, Clipper alters it, sets in dB.
Type Sof t /Hard knee – controls whether the bend in the response curve below Threshold is
abrupt (hard) or gradual (soft). A soft knee slowly changes the curve towards the clipped signal.
A hard knee would be more noticeable.
Knee - available only for soft knee, determines the knee smoothness.
Out put gain - you can adjust TX audio signal amplitude after processing, but before modulator.
In the Prof ile tab, you can save settings of the whole TX processing module in a separate
module, independent from the main software profile. Load PROC settings from a file by pressing
the I mport button and save a profile in a file by pressing the Export button.
To add a new profile, enter unique name in the input box and press the Enter button on your
keyboard. You may also delete selected profile, by pressing the -

Save f or each microphone – enable this checkbox to save all PROC settings separately for
each microphone. E.g. you set your Mic1 settings, then switched to Mic2, changed some
