A free memory-channel programmer for Yaesu and Icom radios. Read the
radio's memories into a file, edit them in a grid or a spreadsheet,
and send them back over the radio's ordinary USB cable. A desktop app
and a command-line tool, rigprog, for macOS, Windows and Linux.
- Edits channels in a grid: keyboard navigation, paste from a spreadsheet, drag to copy, swap or move, and a picker for every column the radio understands.
- Reads and writes over the USB cable, with the radio's menu settings shown alongside on the Yaesu models.
- Imports and exports CSV, including CHIRP's, and reports anything a file cannot carry.
- Keeps your radio safe: it reads before it writes, saves a snapshot, shows every change for approval, and reads each channel back after writing it. Nothing is deleted and no menu setting is changed, ever.
- Costs nothing and hides nothing: GPL, with every protocol fact cited to the maker's manual, so it can stand in for the paid vendor programmers.
| Radio | Read | Write |

| IC-R8600 (a receiver) | ✅ |
Only the FT-710 has ever been connected to this program. The others were built from the makers' protocol manuals and tested against simulators: reading them is safe, and writing stays switched off until you switch it on for that radio. Per-radio detail, including where the program is guessing, is in docs/radio-notes.md. Kenwood radios are next.
Everything is on the Releases page, with a
SHA256SUMS file to check any download.
- macOS: unzip the app. It is not notarised, so the first time, right-click it and choose Open. The command-line tool is a separate tarball.
- Windows: run the installer for your machine (amd64 or ARM64; the amd64 one refuses to run on an ARM64 PC). SmartScreen will say Windows protected your PC: click More info, then Run anyway. The zip is the command-line tool alone. docs/windows-setup.md covers the serial driver.
- Linux: on Debian, Ubuntu or Mint,
sudo apt install ./<file>.debinstalls the app, the command line, a menu entry and the serial-port rule. Elsewhere, the tarball is a single static binary. docs/linux-setup.md covers thedialoutgroup and ModemManager.
Choose the radio and the port, connect (or pick Demo to try it with a simulated radio), read, edit in the grid, then Send. Before anything is transmitted, the app shows every change it is about to make, and anything it refuses to make, with the reason.
The radio's USB adapter appears as two serial ports and only one answers; on macOS only the right one will open, on Windows probe each COM port in turn. The FT-710 needs firmware V01-10 or later.
The command line does the same job for scripts and backups:
rigprog read --port /dev/cu.SLAB_USBtoUART --out radio.json # save the memories
rigprog write --port /dev/cu.SLAB_USBtoUART edited.json # preview, then sendrigprog help lists the rest: ports, probe, diff, export,
import, settings and version. Add --model IC-7300 for another
radio, or --fake for the simulator.
Every write command for the opt-in radios comes from the maker's own manual, but none has been proven on a real radio, so the program refuses to send any of them until you say so:
rigprog settings unverified-writes IC-7610 on # allow writes to the IC-7610The app asks the same question the first time you connect to one of these radios, and its Unverified writes… button opens the list at any time. Both share one settings file. Permission changes what the program may send, not how carefully it sends it: the preview, the snapshot and the read-back still run.
- Channels cannot be deleted, and menu settings are never written (docs/menu-write-decision.md); Icom menus are not read.
- On the FT-710, tone, scan-skip and clarifier cannot be set over CAT, so edits to them are refused rather than dropped.
- Everything per radio, from speed guesses to channels that are not read, is in docs/radio-notes.md.
A report from a real radio is the most useful thing anyone can send:
any radio in the opt-in rows, an FT-710 on Linux, or an FT-710 on an
amd64 Windows PC. Open an issue with the
output of rigprog version and rigprog probe; one channel's line
from a read is plenty, since a whole memory file carries your callsign.
docs/developing.md covers building from source, the repository layout, the evidence records and releasing; CHANGELOG.md lists what changed in each release.
