The version of fldigi differs depending on the repositories that different Linux distributions use.

Introduction

A radio amateur approached me and asked me to help him “translate the fldigi program into Russian.” I named the setting in the Windows version: the language switch is located in Configure - Config Dialog - UI - General - UI language - Russian (Russian) - click Save, then Close and restart the application.

fldigi is a program for conducting QSOs using digital modes of radio communication.

In Linux version Russian language appears automatically during installation from the operating system repository, if the program version fldigi 4.0.1 and higher.Source - https://www.dxzone.com/fldigi-4-0-1-released/.

Official help for the program from w1hkj says the following:

The "UI language" selector is only present on the Windows version of fldigi.

What does it mean:

The "User Interface Language" selector is only present in the Windows version of fldigi.

Translation into Russian by Alexandr Kalugin RX9CDR.

In total, fldigi supports the following languages:

1. English
2. Spanish
3. German (Deutsch)
4. French
5. Italian (Italiano)
6. Polish (Język)
7. Dutch (Nederlands)
8. Russian

9. Greek (Ελληνικά)

Language selection in FLdigi occurs automatically, depending on the language selected when installing the Linux operating system. There is a way to run in a language other than the OS language.

An example of launching fldigi, the menus of which will be translated into Italian:

LANGUAGE=it_IT fldigi

Launching Fldigi with Russian language in an operating system where English is set as the main language:

LANGUAGE=ru_RU fldigi

Version of fldigi in the antiX 23.1 distribution

antiX 23.1 is based on debian 12 bookworm (stable), so the fldigi version is exactly the same as the version in the base OS.

| antiX version | fldigi version |

|---|---|
| antiX 23.1 | 4.1.23-1 |
I checked this myself, by the team fldigi --version.

LxLE version of fldigi

The LxLE operating system is suitable for older PCs.
The lightweight LxLE distribution is based on the Ubuntu 20.04 LTS OS ("Focal Fossa").
LxLE runs on my netbook with an AMD C-30 processor (1 core, 1 thread, 1200 MHz).
Unfortunately, the development of the LxLE distribution has been discontinued - it has moved to "stopped distributions". ISO image for "Focal Fossa" version available, but support for the Ubuntu 20.04 base OS will end on May 31, 2025 ("EOL").

Version of FLdigi from the FlatPak package management system

When using FlatPak, the application version does not depend on the Linux distribution.

The only peculiarity is that the fldigi user macros are stored in a different folder

• instead of/home/user/.fldigi/macros/macros.mdf
  
  *can be stored in /home/user/.var/app/com.w1hkj.fldigi/.fldigi/macros/macros.mdf

Installing applications fldigi,flrig from Flathub— app store for Flatpak.

sudo apt install flatpak
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak install flathub com.w1hkj.fldigi
flatpak install com.w1hkj.flrig

Launch fldigi - from the command line or from the "Start - Ham Radio" menu.

flatpak run com.w1hkj.fldigi

From Flathub, I checked, version 4.2.06 is installed.

Conclusion

Since the versions of fldigi 4.1.x and 4.2.x packages exceed 4.0.1, the Russian language should be, and it yes:

• in Linux:
  • when installing fldigi with the command  `apt install fldigi`  from official repositories,
  • from the FlatPak application store.
• in Windows - after installation from setup.exe, run fldigi and select Russian in the settings: Configure - Config Dialog - UI - General - UI language - Russian (Russian) - click Save, and Close, restart the application.

Problems with Russification most likely relate to an earlier version (3rd), or relate to untranslated items (in English), for example, “Configuration” - “Test signals”, or to reference documentation located on website by Dave Freese W1HKJ.
