Finding the right logging software for Linux can transform your shack setup from clunky to seamless. In this article, we’ll explore the top contenders, highlight their strengths, and wrap up with a handy comparison table to help you decide. All picks are free and open-source, installable via your distro’s package manager (e.g., apt install cqrlog on Debian-based systems) or from the source. Let’s dive in.
Linux shines for ham radio due to its stability, low resource footprint, and tight integration with tools like Hamlib for rig control. No more Wine headaches or VM overhead— these apps are built for your penguin-powered rig. Plus, with community support from forums like Reddit’s r/amateurradio and eHam.net, troubleshooting is a breeze. Expect features like ADIF/Cabrillo exports, DX cluster connectivity, and callbook lookups (QRZ, HamQTH) across the board.
Top Ham Radio Logging Software for Linux
1. CQRLog: The Powerhouse for Serious Operators
CQRLog stands out as the undisputed king of Linux ham logging in 2025. This MySQL-based beast handles everything from daily HF/CW/SSB logs to contest entries with finesse. Key highlights:
- Rig Control: Seamless Hamlib integration for 140+ radios, including IP-based control for modern rigs like the IC-7300.
- Features Galore: DX cluster telnet, grayline maps, internal QSL manager, and auto-uploads to LoTW/eQSL. Its country resolution (powered by OK1RR tables) is spot-on for awards like DXCC or WAZ.
- User Experience: Clean GTK interface with multi-log support. Great for multi-op stations.
- Pros: Feature-rich, stable, and actively maintained. Integrates beautifully with FLDigi and WSJT-X.
- Cons: Steeper learning curve for newbies; requires MySQL setup (though it’s embedded).
- Installation:
sudo apt install cqrlog(Ubuntu) or download from cqrlog.com.
If you’re logging hundreds of QSOs a month, this is your go-to. Users rave about its reliability on low-power setups like Raspberry Pi.
2. Xlog: Simple and Reliable for Everyday Use
For those who want no-frills logging without the bloat, Xlog is a GTK-based gem that’s been rock-solid since the early 2000s. It’s perfect for VHF/UHF ops or beginners.
- Core Functionality: Text-file-based logs with easy add/edit/delete. Displays recent QSOs at the top, calculates bearings/distances, and supports DXCC scoring.
- Extras: Hamlib rig control, world map for grid locators, and QSL label printing via glabels integration.
- Pros: Lightweight (runs on ancient hardware), exports to ADIF/Cabrillo/TRLog/EDI, and pairs effortlessly with FLDigi for digital modes.
- Cons: Lacks built-in contest modes or online uploads—pair it with scripts for LoTW.
- Installation:
sudo apt install xlog—available in most repos.
Xlog’s simplicity makes it ideal for portable ops or as a secondary logger.
3. TLF: The Contester’s Console Warrior
TLF (The Logging Facility) is a text-mode (ncurses) powerhouse for contests, but it doubles as a general logger. If you love keyboard-driven efficiency, this is it.
- Contest Focus: Supports CQWW, WPX, ARRL DX, and dozens more with scoring, networking for multi-op, and CW/voice keying via sound card.
- General Use: DX cluster client, Hamlib rig control, and macro support for quick entries.
- Pros: Ultra-lightweight, no GUI overhead—perfect for remote or headless setups. Exports to Cabrillo for submissions.
- Cons: Steep learning curve if you’re GUI-spoiled; not as polished for casual DXing.
- Installation:
sudo apt install tlf.
Contesters swear by TLF for its speed during high-rate pileups.
4. QLog: Cross-Platform Elegance
QLog brings a modern Qt interface to Linux (and beyond), making it a fresh alternative for 2025. SQLite backend keeps things snappy.
- Standout Features: ADIF imports/exports, rig control, awards tracking, and satellite mode support. Clean UI with dark mode.
- Pros: Intuitive for N1MM refugees, active development, and cross-platform (easy file sharing with Windows/Mac buddies).
- Cons: Younger project, so fewer contest templates than CQRLog.
- Installation: Flatpak via Flathub or build from GitHub.
Great for ops wanting a polished, future-proof logger.
5. jLog: The Java All-Rounder
jLog is a cross-platform Java app that’s surprisingly capable on Linux. It’s web-like in feel but packs ham-specific punch.
- Highlights: Built-in propagation predictions, QSL image uploads, and eQSL/LoTW integration.
- Pros: Runs anywhere Java does (including Raspberry Pi), with strong digital mode ties.
- Cons: Java dependency might irk purists; UI feels dated.
- Installation: Download JAR from sourceforge.net/projects/jlog.
A solid pick for multi-device workflows.

Xlog | Yes (Hamlib) | Basic (keyer macros) | World map, scoring (DXCC/WAS), QSL labels | Casual/VHF logging |
TLF | Yes (Hamlib) | Excellent (50+ contests) | Networking, CW keying, DX cluster | Contesting |
QLog | Yes (Hamlib) | Basic | Modern UI, satellite modes, awards tracking | Cross-platform users |
jLog | Limited | Basic | Propagation, QSL images, Java portability | Multi-device ops |
Honorable Mentions
- Not1MM: N1MM-inspired contest logger for Linux—great if you miss Windows tools.
- HAMRS: Portable-focused for POTA/SOTA, with Linux support.
- KLog: Basic but scriptable for custom needs.
For most Linux hams, CQRLog edges out as the best overall—it’s comprehensive without overwhelming. If contests are your jam, fire up TLF. Start with Xlog for simplicity, and scale up as needed. Test a few via live USB (try Ubuntu Ham edition for pre-loaded goodies). Whichever you pick, integrate it with FLDigi or WSJT-X for a full-stack setup.
Ham radio logging isn’t just about jotting down frequencies and callsigns—it’s about tracking QSOs, managing awards, integrating with rig control, and exporting data for LoTW or eQSL without breaking a sweat. In 2025, Linux offers a robust selection of free, open-source tools that rival (and often surpass) their Windows counterparts. Whether you’re a casual DXer or a hardcore contester, these programs run natively on distributions like Ubuntu, Fedora, or even lightweight setups on a Raspberry Pi.
