Icom IC-7400 programming software
Open WebCHIRPWebCHIRP programs the Icom IC-7400 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
Icom 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 IC-7400?
Icom publishes firmware updates, though not for every radio it has made. Its download page is where to check whether the IC-7400 is one of them. Many older models have no firmware download at all.
Firmware downloads at icomjapan.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 Icom IC-7400?
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 Icom CPS software?
No. WebCHIRP runs CHIRP's own Icom IC-7400 driver in the browser, so it reads and writes the same codeplug the desktop software does.
How many channels does the Icom IC-7400 hold?
99, numbered 1 to 99 in the channel table.
