# Maps and Antennas

## Main view

The Main view is **two configurable panes** (per profile, Settings → General →
*Main view*), with a **draggable divider** between them (double-click it to
even them out). Choose from: great-circle map, locator (street) map, the
cluster grid, the worked-before grid, recent QSOs, the **FlexRadio** controls,
the **Icom** or **Yaesu** console, or the **Net control** panel.

## Great-circle map

- Short/long-path **distance & azimuth** to the worked station.
- Selectable, **key-free** basemaps: Light / Voyager / Street / Satellite.
- The **antenna beam lobe(s)** are drawn from the rotor azimuth.
- **Day/night terminator** and twilight band (button at the top right).

## Locator (street) map

An OSM street map centred on the contacted grid square — handy for local /
portable contacts. No API key.

## Rotators

An azimuthal-equidistant **click-to-turn** compass; the current heading and
target are shown. Three rotator types (Settings → Rotator):

- **PstRotator** — via its UDP interface.
- **microHAM ARCO** — native, over LAN or USB: set the ARCO's CONTROL PROTOCOL
  to *Yaesu GS-232A*.
- **GS-232A (generic)** — any GS-232A controller, ERC (Easy Rotor Control)
  included; serial speed selectable. Set an ERC to GS-232 emulation, not
  Hy-Gain DCU-1.

## Motorized antennas (Ultrabeam / SteppIR)

Both follow the **rig frequency** (band change → retune) and retune immediately
when you click a spot, with three modes — **Normal**, **180° reverse**,
**Bidirectional**:

- The **radiating direction** is shown in green and the **mechanical boom** in
  grey, on both the compass and the map.
- On a FlexRadio, transmit is **inhibited while the elements move**, and
  released as soon as the antenna is tuned.
- **SteppIR — Tunable range** (Settings → Hardware → Antenna, default
  13–54 MHz): outside it OpsLog leaves the antenna and the TX interlock
  completely alone, so tuning to 30 m on a 20 m–6 m SteppIR does nothing.
