OpenHPSDR Zeus User Guide

Welcome to OpenHPSDR Zeus — a web-based client for HPSDR (Protocol 1) radios such as the Hermes Lite 2, ANAN, and other original-protocol boards. This wiki is a user-facing tour of every control you will find in the OpenHPSDR Zeus interface. It does not cover build or protocol internals.

If you are new to OpenHPSDR Zeus, start at Installation, then Getting Started.

What OpenHPSDR Zeus looks like

The OpenHPSDR Zeus window is organised top-to-bottom into seven main areas:

1. Top bar — radio title, VFO A, live status chips, connect/disconnect, rotator, and QRZ controls.
2. Control strip — mode, band, bandwidth presets, front-end, AGC, zoom, drive, and mic.
3. Bandwidth visualizer — low/high cut sliders over a spectrum preview, with preset bandwidths.
4. Hero panel — panadapter, waterfall, and (when QRZ is engaged) the great-circle world map.
5. Right-side stack — frequency (VFO) display, S-meter, QRZ lookup card, DSP controls, CW keyer.
6. Bottom row — logbook and TX stage meters.
7. Transport bar — MOX, TUNE, audio mute, mic level, and status chips.

A note about defaults

OpenHPSDR Zeus is designed to feel familiar to operators coming from Thetis. Sensible defaults are chosen where possible (for example, AGC-T at 80 dB, 2.7 kHz SSB filter, band-memory per band). If a default surprises you, please open an issue — don't assume it is wrong for everyone, but we do want to hear about it.
