6-2-5 Frequency tuning with "center" button OFF
With this setting, the spectrum remains fixed, whereas the yellow tuning
dial will jump to whatever frequency you double clicked on the spectrum.
This mode is convenient if you want to search through frequencies
between a fixed start and end frequency. Also, in the waterfall mode
(see image below), you can keep track of active frequencies (vertical lines) no matter what frequency you are actually
listening to.
6-2-6 Span
The span is the width of the main spectrum window. You can chose
between 900.9kHz, 450.4kHz, 225.2kHz, 112.6kHz, 56.3kHz, 28.2kHz,
14.1kHz, 7.0kHz, 3.5kHz.
Used in both live reception and playback.
Please note that in order to provide the best possible spectrum accuracy, as per the rule 1FFT bin = 1 pixel, and to
avoid resampling the spectral data, the full bandwidth of 900kHz can only be displayed when the program window is
shrinked to its minimum width.
6-2-7 Waterfall control
a) Speed, brightness, contrast
11
The 3 sliders on the far
right side of the spectrum
window allow adjusting of
the waterfall's speed,
brightness and contrast
for optimal viewing.
