Check the Radio's Live DC Supply Voltage¶
The Meters applet shows the supply voltage reported live by the radio. Use it to confirm your DC power source is within a healthy range during operation.
Before you start¶
- AetherSDR must be connected to the radio. The Meters applet requires an active radio connection.
- The applet panel must be visible. If it is hidden, enable it via
View > Applet Panel.
Steps¶
- Click the MTR tray button on the right sidebar to open the Meters applet.
- Read the +13.8V gauge. The label in the center of the bar updates live to show the current voltage — for example,
+13.82V.
What each control does¶
| Gauge | Valid range | Red above | Behavior |
|---|---|---|---|
| +13.8V | 10.0–16.0 V | 15 V | Displays the supply voltage reported by the radio. The gauge label updates dynamically to reflect the live value (e.g. +13.82V). |
There is no persisted setting key for this gauge. It has no configurable default.
Tips¶
- The gauge label changes on every telemetry update from the radio, so the value shown in the bar center is always current — it is not a static placeholder.
- The bar fills cyan in the normal range and turns red above 15 V. A red bar indicates a supply voltage that is above the expected operating range.
Troubleshooting¶
- Gauge shows no movement or a fixed label — The radio is not connected, or the telemetry stream has not started. Confirm the connection status and reconnect via
Settings > Connect to Radio....
