The Stations tab shows a globe with the stations and satellites on the server, and a station list beside it.

Station lists

World list with a search field, the filters All, Ground, Satellites and On air, four public stations such as Demo harbour club on 14.2650 MHz USB, and ad-hoc sessions such as DEMO10 on 5.3570 MHz FT8. — The World list with public stations and ad-hoc sessions, each showing what it is running.

List	Shows
Mine	Your ground stations and satellites, with New station and Launch satellite.
World	Public stations, Ad-hoc sessions and satellites In orbit.

In World, search by callsign, owner or frequency, and filter by All, Ground, Satellites or On air. Each row shows what is running, for example 2 on air or RX, and for satellites the next pass. Select a row or a marker to open the station's details; Show on globe moves the globe to it.

The globe

Drag to turn the globe and scroll to zoom.

Marker or line	Meaning
Your station	One of your stations.
On air	A station with a transmission running.
Listening	A station with a receiver running.
Satellite	A satellite at its current position.
New satellite	The satellite you are designing.
Your RX	Your ad-hoc receive location.
Dashed line from a station	A satellite above that station's horizon.
Line along a heading	A rotator antenna's heading; see Rotators and tracking.

The legend in the lower left also shows the simulation time in UTC. Day and night shading follows that clock. Selecting a satellite draws its ground track.

Button	What it does
Refresh	Reloads the station list.
Coverage	Shows the coverage of your Transmit station (see below).
Orbits	Shows or hides the orbit rings of all satellites.
Fit button	Zooms out to show all stations.

Coverage maps

A coverage map shades the parts of the world where your Transmit station can be heard right now. Brighter shading means a stronger signal.

In the Transmit tab, choose a ground station under Transmit from and set the frequency, power and mode.
In the Stations tab, press Coverage. The button reads Computing… until the map arrives.
Press Hide coverage to remove it.

The map uses the station's location and antenna, the rotator heading, the power up to the radio's cap, the frequency, mode and bandwidth, and the current propagation conditions. It is approximate. After changing any of these, press Hide coverage and Coverage again. Coverage maps work for ground stations only.

Passes and satellites

Pass predictions are in a satellite's details; see Satellites.
