Top Bar and Status
The top bar runs across the full width of the OpenHPSDR Zeus window and is where you connect to the radio and see its live state at a glance.
-
ZEUS — the project title and a sub-line showing the detected board (e.g.
HERMES LITE 2 · 0.1–54 MHz). Informational only. -
VFO A — a compact display of the current RX frequency in MHz (e.g.
14.200). To change the frequency, use the large VFO panel on the right — see Frequency and VFO.
These chips are read-outs, not buttons. They reflect whatever you have set elsewhere in the UI.
| Chip | What it shows |
|---|---|
| MODE | Current RX mode (USB, LSB, CWU, CWL, AM, SAM, DSB, FM, DIGU, DIGL). |
| BAND | Current band (160m–10m). |
| AGC-T | AGC threshold in dB (0–120). Default 80. |
| BW | Active filter low/high cut, e.g. 150…2850 Hz. |
| TX / RX | Shows TX when MOX or TUNE is active, RX otherwise. |

RADIO
<ip:port>— IP address and port of the discovered/connected radio. -
Disconnect — breaks the link to the radio and returns to the Discover dialog. Before connection this slot is occupied by the Discover dialog itself.
-
Rotator pill —
● Rotator: 113°when a rotator is connected. Click it to open a small ROTCTLD popover where you set:-
Host (default
127.0.0.1) -
Port (default
4533) -
Enabled checkbox + Test / Stop buttons
Settings are remembered locally; the backend holds no persistent rotator state across restarts. Use Hamlib's
rotctld -m 2 -r /dev/ttyUSB0 -s 9600 -t 4533(or model2dummy) to drive a rotator from OpenHPSDR Zeus.
-
Host (default
-
QRZ pill —
● <YOUR_CALLSIGN>when authenticated,○ Sign in to QRZotherwise. Click to open a sign-in form (username + password). The credentials are sent to the backend, which fetches a QRZ XML session key; the password is not stored locally. Once authenticated the pill goes green. -
Engage QRZ / QRZ ENGAGED — toggle button.
- Off — the right-column card is a simple compass great-circle map; OpenHPSDR Zeus does not look up callsigns automatically.
- On — the right-column card becomes the QRZ.com Lookup panel, the panadapter grows a translucent world map behind the waterfall, and the panadapter header gains the SP / LP / BEAM / Go rotator-aim controls. See QRZ Lookup and World Map.
-
MENU — opens the settings menu (display options, panel reordering, palettes, etc.).
On viewports narrower than about 900 px the rotator pill, QRZ pill, and Engage QRZ button are hidden to save space. The VFO A readout and MODE / BAND / TX–RX chips remain visible.
