Richard Didd has released OFFgrid-SDR, a fully offline RTL-SDR receiver that runs in a single HTML file without requiring any installation or internet access. The program utilizes WebUSB in modern browsers to demodulate various signal types and display spectrum and waterfall data, while also including built-in decoders for RDS, weather fax, and Morse code. Its primary advantage is portability, allowing users to store the application on a USB drive and run it on almost any machine with a compatible browser.
