The zoom in and out buttons change the displayed signal bandwidth
in 2 kHz steps, while trying to keep the central red marker as close as possible
to the center of the spectrum display. Using the zoom buttons, the displayed
bandwidth can be changed from the default 20 kHz down to 4 kHz, making it
possible to observe small details of the received spectra less than 20 Hz apart.
Setting and Adjusting IF Bandwidth
The receiver IF bandwidth can be set in several ways. The quickest way is to
use the IF bandwidth presets represented by the row of buttons at the bottom
of the demodulator window:
The numbers on the buttons represent bandwidth in kHz.
