Radioddity GM-30 programming software
Open WebCHIRPWebCHIRP programs the Radioddity GM-30 in your browser. It runs the CHIRP project's own driver for this radio, so it reads and writes the same codeplug the desktop software does — without installing anything.
No driver install needed
Radioddity programming cables use a CH340, CP2102, PL2303 or FTDI USB-serial chip. WebCHIRP speaks to all four directly from the browser, so there is no driver package to download and no Windows version to match. Plug the cable in and pick the port when the browser asks.
