Welcome to the SimTX Wiki, the documentation for the SimTX radio simulation platform. These pages cover the SimTX Transmitter desktop application: station setup, transmitting, antennas and the calculations behind them.

Start here

• SimTX Transmitter: what the software is and how it fits together
• Getting Started: connect to a server and make a first transmission
• Transmitter Interface: reference for every control in the window

Operating

• Modulation Modes
• Transmission Sources
• Radio Presets
• Advanced Transmitter Settings
• Station Configuration
• Sessions and Queueing
• Power Amplifier Behaviour
• SWR and Transmitter Protection

Antennas

• Antenna System: overview and configuration
• Types: Dipole Antenna · Inverted-V Antenna · Vertical Antenna · Yagi Antenna · Full-Wave Loop Antenna · Longwire Antenna · Beverage Antenna · End-Fed Half-Wave Antenna
• NEC File Import: custom antenna geometries
• Antenna Calculations: sizing, decibels, SWR arithmetic

Understanding the simulation

• Propagation Basics: groundwave, skywave, MUF and LUF, noise, and whether a signal will be heard
