Use the virtual wheel to tune the active slice

Use the on-screen virtual tuning wheel in the AetherControl dialog to change the frequency of the currently active slice with mouse or trackpad gestures, simulating the feel of a physical rotary controller.

Before you start

• Open the AetherControl dialog: Settings > AetherControl...

Steps

1. In the AetherControl dialog, locate the Wheel control at the top. It shows the current slice frequency and mode.
2. Double-click the wheel to capture mouse input for circular tuning. The wheel becomes active for tuning gestures.
3. Drag in a circular motion around the wheel to tune. Drag clockwise to increase frequency, counter-clockwise to decrease.
4. To release the mouse capture, double-click the wheel again. Press Escape as a secondary release path.
5. (Optional) To reverse the tuning direction, click Reverse.
6. (Optional) To enable panadapter-based tuning, click External Spin. When enabled, dragging on the panadapter also triggers spin-wheel tuning.

What each control does

Control	Default	Range	Setting key
Wheel	—	—	None (renders current slice)
Physical	—	—	None (shows connection state)
Compact	Off	On/Off	None
External Spin	Off	On/Off	FlexControlVirtualExternalSpin
Reverse	Off	On/Off	FlexControlInvertDir
Push (action)	—	—	FlexControlButtonAction_*
Double-tap (action)	—	—	None
Wheel Tightness	45	0–100 (0 = tight, 100 = loose)	FlexControlVirtualWheel (nested JSON looseness field)
Mouse Sensitivity	50	0–100 (0 = less, 100 = more)	FlexControlVirtualWheel (nested JSON sensitivity field)
Aux buttons 1–5	—	5 buttons	None

Wheel action options

The following actions are available for wheel-based controls (Push, Double-tap, and aux button combos):

Action ID	Description
WheelRit	RIT (Receive Incremental Tuning)
WheelXit	XIT (Transmit Incremental Tuning)
WheelVolume	Master Volume
WheelSliceAudio	Slice Audio Volume
WheelHeadphoneVolume	Headphone Volume
WheelAgcT	AGCT (Automatic Gain Control Threshold)
WheelApf	APF (Audio Peaking Filter)

Auxiliary buttons

The dialog provides five configurable auxiliary buttons (labeled with aux dots to indicate active selection). Each button has:

• Aux single-tap combo: Assigns an action to single-tapping the selected aux button.
• Aux double-tap combo: Assigns an action to double-tapping the selected aux button.

These settings are stored per aux button.

Tips

• Mouse capture has been simplified to a single double-click toggle: double-click to capture, double-click again to release. This replaces the previous click-to-capture, Escape-to-release behavior for a cleaner user experience.
• The virtual wheel responds to circular mouse or trackpad drags. Single-event pointer deltas are clamped to 15° (π/12 radians) per event to reduce jitter.
• When your pointer crosses through the center dead zone, the anchor resets. The next movement starts a new tuning gesture without computing a delta.
• Wheel Tightness and Mouse Sensitivity are stored together in a single JSON object under FlexControlVirtualWheel. In earlier versions, Wheel Tightness was stored separately as FlexControlVirtualWheelLooseness; this is auto-migrated on first read.
• The wheel shows the slice frequency in Hz and the current mode (e.g., USB, CW, AM).
• Click Compact to toggle compact mode, which hides auxiliary buttons and shows only the wheel and frequency for a minimal UI.
• The Physical indicator shows physical FlexControl connection state and port name. Use the Detect/Close buttons to manage the physical device.
