Welcome to HOERWACHE,

the simulation designed for former maritime radio officers and radio amateurs!

Immerse yourself in the fascinating world of maritime radio communication, where you can receive real-time weather reports and storm warnings. Our simulation allows you to send and receive messages through a WebSocket connection.

At the core of the radio station, you’ll find a main receiver with frequencies ranging from 400 kHz to 28,000 kHz, divided into various bands that can be selected using a band selector switch. An activity indicator keeps you informed about the currently active transmissions. Additionally, we have a dedicated emergency receiver operating solely on the distress and calling frequency of 500 kHz.

Operate our transmitter in chat mode or key mode, and experience the thrill of classic maritime radio communication. In chat mode, you can enter characters through a text field, which will be sent to all connected stations and converted into Morse code audible on your computer. Choose between direct mode, where characters are directly transmitted from the keyboard through the WebSocket interface, or storage mode, where you can enter the text first and then send it with a single click.

For a truly authentic experience, you can connect a Morse key and a tone generator to the sound card (microphone) and manually key the transmitter. The simulation also features a dynamic nautical chart displaying your ship’s position, as well as its speed. You can navigate the ship using a compass, but it will typically follow a predefined route that you can select when starting the radio station.

HOERWACHE can be operated as either a ship station or a coastal radio station. We have a comprehensive database of over 300 coastal radio stations available in the program.

It’s important to note that HOERWACHE is a passion project and completely free of charge. We believe in the spirit of sharing knowledge and fostering a sense of community among former maritime radio officers and radio amateurs. This simulation is our way of celebrating the rich history and skills of this unique profession. Join us on this exciting journey and experience HOERWACHE without any cost or obligations.

Welcome to HOERWACHE – your gateway to the world of maritime radio!
