Open the output configuration dialog

Click the button with three dots in the Edit column for the row created in the previous step.

On the Sim Variable tab, use the Filter Preset List dropdowns to filter by Microsoft, Generic, and Radio.

Select the COM 1 active frequency preset

Set the radio index

Since aircraft have more than one radio, MobiFlight will show a dialog to specify the COM radio value to display. Use the dialog to specify index 1.

Select the board and device type for the output

On the Display tab, use the Module and Use type of dropdowns to select your connected board and the Display Module device type.

Select the module to use for display

Use the Name / Number dropdown to select the module that should display the output value. If more than one module is connected in series, use the number dropdown to specify which module in series will display the value.

Specify the digits and decimal point for display

Use the use display checkboxes to specify the six digits to use for the frequency display. Use the set decimal point checkbox to specify where the decimal point should display.

Close the dialog and try it out

Click the OK button to close the dialog, then spawn an airplane in Microsoft Flight Simulator.

Make sure the MobiFlight Run button is clicked in the toolbar, then verify the display shows the COM1 active frequency.
