FLDIGI Users Manual 4.0
The same control is used for both manual entry of the transceiver frequency or with full CAT control. When no CAT is available the control is simply a convenient way of keeping track of the transceiver USB/LSB suppressed carrier frequency, the mode and the audio tracking point. If fldigi is being used with an FM transceiver you probably should enter the simplex frequency or the input frequency of a repeater being used. This frequency value is used with the waterfall audio frequency to compute the logged frequency. The logged frequency value will only be correct for LSB and USB operation.
The combo box on the left will allow the selection and control of the operating mode of the transceiver.
The combo box on the right will allow the selection and control of the transceiver bandwidth.
The frequency display is in fact a set of special buttons. Each digit may be increment by clicking/pressing on the upper half of the digit and decrement by clicking/pressing the lower half of the digit. The leading digits will follow suit if a decade rollover occurs. You can also place the mouse cursor on a digit and then use the mouse wheel to roll the frequency up and down.
Manual entry of frequency can be accomplished by hovering the mouse pointer over the frequency display and entering the desired frequency (in Khz) via the keyboard. Pressing <return> or <enter> on completion sets the frequency to an active state, effecting rig control and future log entires. Don't forget the decimal point if you are entering a fractional KHz value.
The Smeter / Power-meter display is only active if fldigi is configured for xmlrpc control with flrig. The transceiver must support the smeter and power out CAT query. fldigi does not try to estimate the smeter reading based on the audio stream. You can toggle viewing the Smeter / Power-meter display using the button just to the right of the shared space used by the "Smeter/Power-meter" and the "Mode/Bandwidth" controls. Be sure to save the configuration for this to persist the next time fldigi is executed.
The mode combobox, the bandwidth combobox and the frequency display also annunciate the current transceiver status. If you change operating mode on the transceiver, that will be annunciated in the respective combobox and FLDigi will adjust any internal parameters accordingly. FLDigi queries the transceiver 10 times per second to maintain a lock step with the transceiver.
The frequency/mode pick list is displayed when the book button is pressed. Pressing the book button a second time will restore the original logging panel.
The pick list buttons control selecting, adding and deleting entries in the frequency/mode list.
The browser list contains frequency, sideband, modem type, audio frequency, and a text describing usage. To edit the usage string:
This will hide the frequencies browser and display the data relative to that line
Edit the text entry and press the "Enter" button when finished.
The list is saved when fldigi is shut down.
