Watch PA temperature during long overs¶
The Meters applet shows a live PA Temp gauge that reads the radio's power amplifier temperature in real time. Keeping this visible during long transmit overs lets you catch thermal buildup before it becomes a problem.
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, use
View > Applet Panelto show it.
Steps¶
- Locate the MTR tray button on the right sidebar of the applet panel.
- Click MTR to toggle the Meters applet open.
- Read the PA Temp gauge under the Radio Hardware section header.
The bar fills from left to right as temperature rises. The bar turns yellow above 55 °C and red above 70 °C.
What each control does¶
| Label | Range | Red threshold | Notes |
|---|---|---|---|
| PA Temp | 0–120 °C | > 70 °C | |
| +13.8V | 10.0–16.0 V | > 15 V | The gauge label updates dynamically to show the live radio-reported voltage (e.g. +13.82V) instead of the static +13.8V placeholder. |
| Main Fan | 0–3000 rpm | > 2500 rpm |
None of these controls have persisted settings keys. They are read-only telemetry displays.
Tips¶
- The gauge uses smoothed ballistics, so brief peaks are visible without causing flicker. Sustained red-zone readings indicate a genuine thermal condition, not a transient spike.
- The supply voltage gauge label reflects the live voltage value reported by the radio. The label updates each time a new reading arrives, so it always shows the current voltage to two decimal places (for example,
+13.82V). - PA current is not shown. On FLEX-8000 series hardware the PA current meter clips under full PA draw, so it has been intentionally omitted.
Troubleshooting¶
- PA Temp gauge shows no movement — The applet only receives data when connected to the radio. Verify the connection status and reconnect via
Settings > Connect to Radio...if needed.
