The Kenwood TS-50 is a reliable 25-year-old mobile HF radio, widely used in DX operations but lacking CAT and DATA ports for modern logging or contest software. To overcome this, a custom CW interface was built using an USB to TTL module (FT232/FT232RL) and an optocoupler (e.g., 4N25, H11A1) for galvanic isolation. This setup enables the TS-50 to connect with a computer via USB, facilitating integration with software like LOGGER32 and Win-Test. The interface is cost-effective and driver-free for Windows XP and 7, making it an accessible solution for enhancing the TS-50's functionality.
