radioM61

radioM61 is a fictional line of compact software-defined radio transceivers conceived for use in science fiction settings and related media. In the in-universe catalog published by the imaginary company M61 Industries, the radioM61 family is presented as a portable, rugged multi-band transceiver intended for amateur radio operations, emergency communications, and field reconnaissance. The device is described as modular, with swappable front ends and a common chassis that can host different frequency modules. It supports a wide frequency range spanning HF and VHF bands, embraces digital signal processing for filtering and demodulation, and runs a compact real-time operating system on an ARM-based controller.

Key features attributed to radioM61 include software-defined radio architecture enabling rapid mode updates, support for voice modes such as CW, SSB, AM and FM, and several digital modes. It offers a graphical user interface with a waterfall display, and provides data interfaces via USB-C and optional wireless links. Power options include an internal rechargeable battery and external supplies, with energy management designed for extended field use. The line includes several variants, such as the base radioM61 and a higher-end radioM61-Pro, plus a kit version for hobbyists and educational programs.

In-universe usage notes mention disaster response simulations, field training exercises, and integration with autonomous communication relays. See also: software-defined radio, amateur radio, field radio.
