RT Systems KRS-D75 Programming software offers a comprehensive solution for managing the Kenwood TH-D75 radio's memory channel information, D-STAR settings, and various menu configurations. Its user-friendly spreadsheet layout features numerous point-and-click options, allowing users to navigate and edit settings efficiently. The software enables users to either "read" the current configuration from the radio for modifications or start fresh with a new file. This flexibility is complemented by the ability to copy and paste memory channel data between files, streamlining the programming process.

The column editing feature is particularly noteworthy, allowing users to change multiple channels with minimal typing effort. Additionally, the software provides an easy interface to RFinder-Worldwide Repeater Directory, Radio Reference, and Repeater Book, enabling users to obtain repeater information relevant to their location, travel routes, or vacation spots. Access to repeater details is available for both U.S. and international locations, although a separate purchase or subscription may be required for some services.

Beyond memory channel programming, RT Systems KRS-D75 offers settings for other radio menu items, making it a versatile tool for enthusiasts. The software is compatible with Windows 8/8.1 (full versions), Windows 10 (32 and 64-bit), and Windows 11, ensuring a broad range of users can use its capabilities. With built-in frequency lists accessible under File|External data, users can often find the necessary frequencies without extensive internet searches, enhancing the overall efficiency of the programming experience.
