If you are a HAM (amateur radio operator) who doesn't have shortwave equipment, or hasn't yet obtained your B license, and you want to experience (to some extent) real shortwave communication, you might try this software: Morse Runner.
Morse Runner is an open-source tool written in Delphi by VE3NEA. http://www.dxatlas.com/MorseRunner/ ), aimed at providing a simulated CW mode for beginners (including those planning to participate in WWX). All the radio chatter you hear is software-simulated, and you'll experience the feeling of frantically trying to decipher the Morse code amidst the static noise.
However, the software simplifies the process for using UniNet: users do not need to manually dispatch calls using an external switch; instead, they can simply click a few buttons to: report the call sign they hear, exchange signal reports, and enter the call sign provided by the other party, as well as record the QSO information.
For specific usage instructions, please refer to the introduction provided by BA4ALC. https://www.qsl.net/ba4alc/chinese/MORSERUNNER/morserunner.html
Please note that the official GitHub repository https://github.com/VE3NEA/MorseRunner The latest version is 1.68, but BH1SCW maintains an updated branch that fixes several bugs and follows the Chinese localization, with a version of 1.72. Friends in China can download this version from his personal website. https://www.bh1scw.com/mr/score
P.S.: My recommended CW mode learning path:
- Morse Mania (Android, level-based challenge learning for initial mastery of each letter's code)
- I2UUF Morse code and CW (Android, slow to medium speed reception and practice of encoding) or
3. Koch Method CW Trainer - G4FON (Windows, a well-known listening and copying software that can add difficulty levels such as QRM, frequency drift, direct keying, and chirp sounds)
4. Morse Runner (This article describes a simulated environment for the "Morse Runner" game, which offers a simple, low-speed, clean background noise, and a variety of difficulty options. The simulation allows you to hear the call signs clearly, but it doesn't matter if you can't hear them perfectly.)
I had previously come across a more advanced simulation radio service (hamsphere.com), which claimed to be "a highly realistic shortwave simulation based on SDR," even simulating propagation using physical characteristics such as Earth topography, atmosphere, solar flares, and flux index, with antennas also modeled using electromagnetic simulation. It was even possible to purchase plugins to upgrade functionality, acquire equipment or antennas (in-app purchases detected!). I haven't tried it myself, so please use it at your own risk, while complying with local laws and regulations.
