WiNRADiO G303 Series Command-Line Switches

 
To facilitate experimentation and special applications of the G3 series receivers, special command-line optional parameters (switches) have been incorporated in the G3 series receiver application software.

 /nd ("no demodulator" command-line switch)

This switch suppresses error generation if no demodulator is found by the G3 application (normally, demodulators are located in the application "Plugins" folder). The application starts up with the demodulator window empty. This is intended for situations where external third-party demodulator software is used.

 /sd ("stop demodulator" command-line switch)

This switch causes the application to ignore any existing demodulators upon start-up, to prevent them from claiming the sound card facilities of the host computer. This serves to a similar purpose as the above /nd switch, but allows to keep original WiNRADiO demodulators in place. (The demodulators can still be selected and started later, using the top bar Demodulators menu.)

 /c ("clock frequency" command-line switch)

This switch makes it possible to disable the internal reference oscillator, and define the frequency of an external reference oscillator. The external reference can be of any frequency between 8 and 20 MHz. For example, if the external frequency is 16.7890124 MHz, this would require the following command-line switch: /c16.7890124. This option is only available on special G3 series receivers, where a provision for an external reference source is fitted, if required for very high tuning accuracy or to achieve phase coherence for multiple-channel systems.

Using Command-Line Switches

You can either type the name of the application in the Windows Run Program edit box, followed by the desired command-line switch, or you can introduce a command-line switch by right-clicking on a desktop icon, selecting Properties, and adding the command-line switch to the Target, for example as follows:

"C:\Program Files\WiNRADiO\G303\WRg3.exe" /sd

You can also copy the desktop icon, for example creating one with the command-line switch, and one without, and renaming the icons to reflect the associated functional differences.

Note that the entire file path name of the Target is enclosed in double quotes, but not the command-line switch (otherwise it would be considered to be part of the executable file name).
