Why You Need a Logging Program
A paper logbook was standard for generations of amateur radio operators. Today, dedicated logging software does everything a paper log does — and far more. It tracks your contacts, looks up call sign data, interfaces with your rig for automatic frequency logging, integrates with the DX cluster, confirms DXCC entities, and even submits your log to award programs electronically. Choosing the right logger can meaningfully improve your operating experience.
What to Look for in Logging Software
Before diving into specific programs, consider what matters most to you:
- General logging vs. contest logging: Some programs excel at everyday QSO logging; others are built specifically for contesting with real-time scoring and exchange management.
- Award tracking: Do you need DXCC tracking, WAS (Worked All States), CQ Zones, or ITU zones?
- Digital mode integration: Does it interface with WSJT-X (FT8), fldigi (PSK31, RTTY), or JS8Call?
- Cluster integration: Does it connect to DX clusters (DX Spider, AR-Cluster) and display spots on a bandmap?
- CAT control: Can it read your radio's frequency and mode automatically via a CAT interface?
- Platform: Windows-only, Mac/Linux, or cross-platform web-based?
Top Logging Programs Reviewed
Log4OM (Windows — Free)
Log4OM (version 2) is one of the most feature-rich free loggers available. It includes comprehensive award tracking (DXCC, WAS, WAZ, IOTA, and more), built-in DX cluster, CAT control, QRZ/HamQTH callsign lookup, and LoTW/eQSL integration. The interface is initially complex but very customizable. Highly recommended for serious DX operators who want everything in one package.
DXKeeper (Windows — Free, part of DXLab Suite)
DXKeeper is part of the renowned DXLab Suite, a collection of tightly integrated amateur radio applications. The suite includes DXKeeper (logger), DXView (mapping/DXCC lookup), SpotCollector (cluster), WinWarbler (digital modes), and more. The integration between modules is seamless and makes the DXLab Suite a powerful end-to-end solution. Windows-only and has an older UI, but the functionality is outstanding.
N1MM Logger+ (Windows — Free)
N1MM Logger+ is the dominant choice for contesting. It supports virtually every amateur radio contest and is used by most serious contest operators worldwide. Real-time scoring, multiplier tracking, SO2R (two-radio) support, and network capabilities for multi-operator stations are all included. It's less ideal as a general everyday logger but unmatched for contest use.
Ham Radio Deluxe (Windows — Paid)
Ham Radio Deluxe (HRD) is a commercial suite that includes a logger, digital modes software (DM780), and a rig control module. It's polished and user-friendly, making it popular with newer operators. However, it carries a subscription fee, which puts some operators off given the quality of free alternatives.
MacLoggerDX (macOS — Paid)
For Mac users, MacLoggerDX is the leading option. It provides comprehensive logging, cluster spotting, DX entity lookup, and a map display. Given the shortage of quality Mac ham radio software, it fills an important niche well.
WSJT-X (Cross-platform — Free)
WSJT-X is not a traditional logger — it's a digital mode application for FT8, FT4, JT65, and other weak-signal modes. However, it maintains its own log and can export to ADIF format for import into any logging program. Essential for any operator working digital modes.

Logbook of the World (LoTW)
Regardless of which logging software you choose, make sure it supports ARRL's Logbook of the World (LoTW). LoTW is the definitive electronic QSL system used for DXCC credit. Contacts confirmed via LoTW count toward your DXCC totals. Most serious DX operators upload their logs to LoTW regularly — often after every operating session.
Starting with a solid logging program early in your ham radio career builds good habits and makes award progress much easier to track. Pick one that suits your operating style and grow into it — most of these programs have far more capability than the average operator ever uses.
