 For VHF/UHF-SUB decoders the signal should appear at the right side to the middle frequency cur-
sor, and
 For SAT (satellite) decoders the middle frequency cursor should be placed at the middle of the sig-
nal.
The values in the “Mode”, “Freq Offset” and “Shift” appear also in the corresponding database fields, to-
gether with “Remarks” and “Date & time”. When a classifier or a classifier code check is running, the result
will be displayed in the “Remarks” field.
The user can Insert or Overwrite the entry into the database by clicking the corresponding button. Using
the Edit button the user can manually change values of a database entry.
Edit a database entry by clicking the “Edit” button.
Wideband Spectrum Display and Media Player/Recorder
In the Operation tab there are two spectrum displays where the user can view signals in a wide spectrum
range and in more detail, respectively.
The wideband spectrum display has a 2 MHz bandwidth. This display usually corresponds to a wideband
spectrum of an SDR, like the DDC1 in WiNRADiO G3xDDC. The spectrum middle is the receiver frequency
(Rx Freq). The user can change the Rx Freq by clicking the mouse at another position in the spectrum.
