Put the tuner in OPERATE, BYPASS, or STANDBY¶
Use the OPERATE button in the Tuner applet to cycle the 4O3A Tuner Genius XL through its three relay states: OPERATE, BYPASS, and STANDBY.
Before you start¶
- AetherSDR must be connected to the radio. The Tuner applet is hidden until a Tuner Genius XL is detected.
- The TUN tray button must be available in the right sidebar, indicating the TGXL has been detected.
Steps¶
- Click the TUN tray button on the right sidebar to open the Tuner applet.
- Locate the OPERATE button in the lower-right area of the applet.
- Click OPERATE to advance to the next state. Each click cycles one step forward:
- OPERATE → BYPASS
- BYPASS → STANDBY
- STANDBY → OPERATE
What each control does¶
| Button | Color when active | Meaning |
|---|---|---|
| OPERATE | Green | Tuner relays are in circuit and active. |
| BYPASS | Orange | Tuner is energized but the matching network is bypassed. |
| STANDBY | Default (blue-grey) | Tuner is not operating. |
The button label and color update immediately when the TGXL acknowledges the state change.
Tips¶
- The button always shows the current state, not the next state. A green OPERATE label means the tuner is already in OPERATE.
- Clicking once from STANDBY returns the tuner to OPERATE and restores the green color. You do not need to pass through BYPASS to get back to OPERATE.
Troubleshooting¶
- The TUN tray button is not visible — The Tuner applet is hidden until a Tuner Genius XL is detected on the network. Verify the TGXL is powered on and connected. See Tuner overview.
- The button label does not change after clicking — The label updates only when the TGXL confirms the new state. If the label stays the same, check the connection between AetherSDR and the TGXL.
