3.9 Entering frequency directly
If you wish to use the keyboard one of the VRX windows must have the focus. In order to enter a
frequency directly with the keyboard and/or mouse:
-
Press the SPACE bar or click on the RX Control frequency dial; this will start the input sequence.
The dial will display 0 and the white frame around the dial will turn to yellow. In order to abort the
input sequence press the ESC key or click on the Clear button in the RX Control window.
-
Enter the frequency in KHz using the numeric keys and/or clicking on the band buttons. If you
wish to enter Hertz values use the decimal separator of your system. For example if you wish to
enter 1455202 Hz type in 1455.202 (or 1455,202 depending on the system). Note: you can use
whatever decimal separator you wish; the program will replace it automatically (if needed) with the
correct one.
-
Press Enter or click the Enter button in the RX Control window. If the value has been accepted the
dial will show the new frequency.
3.10 Minimize/Restore All option
As the SDRuno GUI is made of many independent windows, an option to minimize or restore all the
windows of an instance with a single action can be very handy sometime. The “minimize-restore all”
option is controlled by the small “MA” button located in the upper left of the Main window. When enabled,
minimizing or restoring the RX Control or the RX EX Control window will result in minimizing or restoring
all the opened windows in the relative SDRuno instance.
3.11 VRX background
The VRX background colour can be customized by the user; the relevant control is located here: RX
Control window->SETT.->MISC->VRX BACKGROUND COLOUR. Currently this parameter only affects
the spectra (MAIN SP and AUX SP) background. In the future the functionality will be extended to all the
VRX windows.
3.12 Using multiple VRX while playing IQ files
SDRuno allows the use of multiple VRX while playing IQ files. Main window->SETT.->MISC->MULTI VRX
WAVE FILE MODE. This option is enabled by default; if you wish to use only VRX#0 uncheck the option.
3.13 RDS
There is
a “DX mode” feature in the RDS decoder. The RDS processing offers “state of the art”
performances, very close to the theoretical limits. Testing has shown that it is still possible to obtain a valid
RDS PI from a signal with only a 10 dB S/N ratio.
