Amplifier overview

The Amplifier applet provides real-time telemetry and OPERATE/STANDBY control for a connected Power Genius XL (PGXL) amplifier. Use it to monitor forward power, SWR, temperature, drain current, and mains voltage without leaving AetherSDR.

Before you start

  • AetherSDR must be connected to a Flex radio.
  • A Power Genius XL amplifier must be detected by the radio. The applet and its tray button are hidden until the radio reports a PGXL.

How it works

The Amplifier applet appears in the right-side applet panel when AetherSDR detects a PGXL amplifier on the network. Toggle it open or closed with the AMP tray button on the right sidebar.

All telemetry is pushed from the radio in real time. The gauges update as the PGXL reports new values; no polling or manual refresh is needed. The OPERATE / STANDBY button reflects the amplifier's current state and lets you switch between the two.

What each control does

Control Kind Behavior Range Red threshold
Fwd Pwr Gauge Shows PGXL forward power output. 0–2000 W > 1500 W
SWR Gauge Shows PGXL SWR at the amplifier output. 1.0–3.0 > 2.5
Temp Gauge Shows PGXL heatsink temperature. 0–100 °C > 80 °C
Volts / Amps Text indicator Displays mains voltage and drain current as Volts: xxxV Amps: x.xA. Hidden until first telemetry arrives. Integer volts, 0.1 A resolution
MEffA Text indicator Displays the PGXL MEffA value. Hidden until the radio reports a value.
OPERATE Button Toggles the amplifier between OPERATE and STANDBY. Hidden until the radio reports amplifier state. Shows OPERATE (green) when the PGXL is in IDLE, OPERATE, TRANSMIT_A, or TRANSMIT_B state. Shows STANDBY when the PGXL is in STANDBY, POWERUP, or FAULT state.

The three gauges use a color-coded bar: green below the yellow threshold, yellow-amber in the caution zone, and red above the red threshold. Tick labels on each gauge are color-matched to their zone.

None of the controls have persisted settings — all values come live from the PGXL.
