SimTX Guide/Stations

A station is the place you transmit and receive from. It is saved to your account and works on every server. A ground station has a name, a callsign, a location, one to eight antennas and up to eight radios. Several transmissions and receivers can use one station at the same time. Satellites are stations in orbit; see Satellites.

You manage stations in the Stations tab. Mine lists your ground stations and satellites; select one to see its details. Map and coverage describes the globe and the lists.

Create a station

1. In the Stations tab, select Mine and press New station. The station editor opens with the sections Basics, Location, Antennas and Radios.
2. Under Basics, enter a Name and your Callsign, and choose Public or Unlisted.
3. Under Location, press Pick on globe, click the globe where the station stands and press Done. You can also drag the pin or type the Latitude and Longitude.
4. Under Antennas, set up the dipole the station starts with, or choose another type.
5. Under Radios, check the radio the station starts with.
6. Press Create station.

Altitude

When you place the station, the app fills in Altitude with the ground height at that spot, in metres above sea level. If you type your own altitude, the app keeps it; Use ground height goes back to the ground height. If the lookup fails, enter the altitude by hand. Antenna height is set on each antenna.

Antennas

Add antenna opens the antenna gallery, grouped as Wire, Beam and Whip and turnstile. NEC deck under Your own model imports a wire model; see NEC File Import.

Field	Meaning
Name	The name shown in the Transmit and Receive tabs.
Type	The antenna type. Changing it resets the length.
Length	The main dimension. Its label depends on the type.
Height	Height above the ground, in metres.
Feedline loss	Loss of the cable to the radio, in dB.
Mount	Fixed, Azimuth rotator or Az-El rotator.
Points toward	On a Fixed mount, the direction of a directional antenna, in degrees from north.
Parks at azimuth, Elevation	On a rotator, where the antenna points when a session starts. Elevation is only on an Az-El rotator.
Check SWR at	The antenna's SWR at a frequency you choose.

Import NEC deck… replaces the built-in model with your own and Use built-in goes back. Remove deletes the antenna; a station keeps at least one. See Antenna System for choosing and tuning, and Rotators and tracking for rotators.

Radios

A radio is a saved transmitter and receiver profile. Add radio adds one; Based on fills in typical values for a radio model.

Field	Meaning
Name	The name shown in the Transmit and Receive tabs.
Power cap	The most power a transmission on this radio can use, in watts.
Noise figure	The receiver noise figure, in dB.
Transmitter imperfections	How the transmitter sounds. See Advanced Transmitter Settings.

• The first radio is the station's default. The Transmit and Receive tabs show it as <name> (default).
• A transmission can't exceed the power cap or your account's power limit, whichever is lower.
• Without a radio, sessions use a generic HF transceiver and your account's power limit.

Public and unlisted

Visibility	Meaning
Public	Shown on the map, and anyone signed in can receive from it.
Unlisted	Hidden from the map and usable only by you.

Only you can transmit through your stations.

Transmit and receive

• Transmit from here in a station's details opens the Transmit tab with the station chosen. See Transmitting.
• Receive here opens the Receive tab with the station chosen. It also works on other people's public stations. See Receiving.

Edit a station

1. Select the station under Mine and press Edit, or press Edit station in the Transmit or Receive tab.
2. Make your changes and press Save.

Running sessions switch to the new settings without reconnecting. A session on an antenna or radio you remove ends; the editor warns before you save.

Delete a station

1. In the station's details or the editor, press Delete….
2. Confirm with Delete station.

The station, its antennas and radios are removed and its sessions end. This can't be undone.

Use my previous setup

With no stations yet, Use my previous setup creates a station from the callsign, location, antenna and radio of your earlier transmit setup.
