Retevis RA25 programming software
Open WebCHIRPWebCHIRP programs the Retevis RA25 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
Retevis 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.

Can I update the firmware on the RA25?
Retevis publishes firmware updates, though not for every radio it has made. Its download page is where to check whether the RA25 is one of them. Its firmware list covers a subset of the range; many entry-level FRS and PMR models are not on it.
Firmware downloads at retevis.com
WebCHIRP does not flash firmware. It reads and writes the channel list and settings over the programming cable, which is a separate part of the radio.

Questions
Do I need to install a USB driver to program the Retevis RA25?
No. WebCHIRP talks to CH340, CP2102, PL2303 or FTDI programming cables from the browser, so there is nothing to install on Windows, macOS or Linux.
Do I need the Retevis CPS software?
No. WebCHIRP runs CHIRP's own Retevis RA25 driver in the browser, so it reads and writes the same codeplug the desktop software does.
How many channels does the Retevis RA25 hold?
502, numbered 1 to 502 in the channel table.
