Main section
Section with parameters of the digital signal processing and its display.
S-meter correction (dB)
— correction value for S-meter readings.
SSB Filter Edge
— sets the steepness of the filter edges in SSB and AM modes. Hard
— high steepness, Medium — medium steepness, Soft — low steepness.
Note: As higher the steepness is set, the bigger the latency between HF and audio signals will
be,
but the better the suppression of neighboring stations will become.
CW Filter Edge
— sets the steepness of the filter curves in CW mode (analog to SSB
Filter Edge).
TX Key
— sets the button of the keyboard for switching the transceiver in the
transmit mode. One mouse click activates the transmitter, a further click will
switch back into the receive mode.
Note: Selected button will led the device in the transmit mode even if the program window is
not the active window
.
DIGI freq. shift
— adjustment of the frequency shift in mode DIGI (analogously to
CW Tone).
Scope FFT Rate
— refresh rate of the spectrum display.
Waterfall FFT Rate
— refresh rate (speed) of the waterfall.
FFT Rate Count
— preset of the number of calculated spectra per time unit. A high
value requires more PC power, but the spectrum display will look more "active".
This parameter has to be increased, to get most out of the function "Pseudo 3D".
FFT Rate Balancing
— on/off switch for the increased number of calculated spectra
for small spectrum bandwidths; the “Yes” setting requires more PC power, but
the spectrum display will look more "active". This is most effective for spectrum
bandwidths of 10 - 20 kHz.
FFT Size
— spectrum resolution in points. A high value enlarges the resolution of the
spectrum and waterfall but requires more PC power.
Note: For spectrum bandwidths of more than 100 kHz the maximum resolution of the spectrum
is 1024 points. If a higher value is selected, it will be used automatically for spectrum
bandwidths of up to 100 kHz only.
FFT Window
– list for selecting the weighting window for the fast Fourier transform
used for spectrum and waterfall display.
