Developer and radio amateur Luigi Cruz has released a brand-new project, designed to make it as easy as possible to get started with software-defined radio: a browser-based interface dubbed CyberRadio Blast.

"New Project Alert: CyberRadio Blast! [It's] a work-in-progress Chrome-based SDR console," Cruz writes of the project. "Currently compatible with the Airspy HF+ Discovery. Chrome Mobile not supported because of threading limitations. Might support more devices and add more features in the future if interest increase."

In its initial release, CyberRadio Blast offers relatively basic functionality: It connects to an Airspy HF+ Discovery software-defined radio via USB and allows the user to tune in to an FM radio station — complete with play, pause, and volume controls for playback.

The software is written in WebAssembly (Wasm) and connects to the radio over WebUSB — and, at present, is exclusively compatible with Google's Chrome browser. If there's enough interest in the initial release, Cruz has indicated that additional features and support for more SDR hardware could be added.

Cruz is also responsible for the PiSDR project, which offers a downloadable operating system image for the Raspberry Pi family of single-board computers with a range of SDR-specific drivers and utilities pre-loaded for a selection of radios including the LimeSDR family, Airspy range, HackRF One, USRP, and RTL-SDR.

Cruz has confirmed that a write-up on the project will be posted to his website soon, while those looking to try the software out in its current early stage can load blast.luigi.ltd in Chrome with an Airspy HF+ Discovery connected.
