Station Configuration

The station identity consists of a callsign, a geographic location and an antenna. Together with the transmitter settings it fully describes the simulated station.

Callsign

A free-form station identifier (default PA3NL). It is shown to the server, in session lists and to other users. Servers may apply per-user session limits keyed by callsign, see Sessions and Queueing. The callsign is persisted between application runs.

Location

Latitude and longitude, set by clicking the world map or typing into the Lat and Lon fields (defaults 52.3676 north, 4.9041 east). Location matters:

• It sets the distance and bearing to every receiver, which drives path loss and antenna directionality.
• It determines local time of day at the station, which affects ionospheric propagation, see Propagation Basics.
• Latitude influences ionospheric behaviour; high-latitude paths are less stable.

The location is persisted between application runs.

Antenna

See Antenna System for the antenna configuration fields and the list of available antenna types.

Station presets

Save Preset... writes the complete configuration to a .stxpreset file: every form field, the radio preset choice, modulation, bandwidth mode, source type and file, microphone selection, antenna type and any imported NEC deck. Load Preset... restores it. These files are ordinary text property files and can be shared between users.

This is a different concept from the built-in Radio Presets, which only describe the transmitter hardware character.
