Polmar DB-50M programming software
Open WebCHIRPWebCHIRP programs the Polmar DB-50M 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
Polmar 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.

Questions
Do I need to install a USB driver to program the Polmar DB-50M?
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 Polmar CPS software?
No. WebCHIRP runs CHIRP's own Polmar DB-50M driver in the browser, so it reads and writes the same codeplug the desktop software does.
How many channels does the Polmar DB-50M hold?
758, numbered 1 to 758 in the channel table.
