# Amplifiers and Switches

## PowerGenius XL (4O3A) amplifier

Direct TCP connection (Settings → PowerGenius):

- **Operate / Standby** and **fault** display.
- **Fan-mode** selector (Standard / Contest / Broadcast).
- When a Flex is connected, the amp controls + its **FWD / ID / TEMP** meters
  appear in the FlexRadio panel's Amplifier card. See [[FlexRadio]].

## Antenna Genius (4O3A) antenna switch

Over TCP / GSCP — a docked **A/B antenna-switch** widget:

- One row per configured antenna, with a **Port A** and **Port B** button.
- Colours: green = selected on port A, blue = selected on port B, red (pulsing) =
  that port is transmitting. Clicking a selected port deselects it (→ None).
- **Band filter** (funnel icon in the header): shows only the antennas configured
  for the current band, like the native app. Toggle it off to see all antennas.
  Antennas with an unknown band mask are always shown.

Configure the host / password in Settings → Antenna Genius.
