It offers features like 200 read/write memories, a programmable scanner, and spectrum scope, making it easier to use than traditional radios. The article explains the benefits of virtualizing a radio with controls and highlights the advantages of using JRX, especially for radios requiring computer control. Author P. Lutus provides insights on the development of JRX and its improvements over previous virtual radio projects.

open890 is a web-based UI for the Kenwood TS-890S amateur radio, and features good usability, clean design, and high-speed bandscope/audio scope displays, among other features not available either on the radio itself, or in the ARCP remote control software. It is currently only designed to interface with the TS-890 via a LAN (or wifi) connection, and not a USB/serial connection. It may work with the TS-990, as the command set is very similar, but is currently untested.
