RadioLog is a free Windows ham radio logbook that looks considerably more capable than a basic QSO logging program. Along with logging contacts, it includes CAT control, DX Cluster integration, digital-mode support, contest logging, POTA and SOTA support, electronic QSL services, statistics, mapping, and even an RTL-SDR auxiliary monitor.
That feature set immediately caught our attention. RadioLog has a modern interface and an unusually broad collection of amateur-radio tools, making it look more like a complete station operating application than a simple electronic logbook.
There is an important qualification, however: we have not yet personally tested RadioLog in an operating station. This review therefore focuses on the current feature set, documentation, interface, and capabilities rather than claiming hands-on experience with its performance or reliability.

What Is RadioLog?
RadioLog is Windows software designed to bring several parts of the amateur-radio operating workflow together in one application.
The central component is the logbook. Around that are tools for controlling a connected transceiver, monitoring DX Cluster spots, looking up callsigns, handling digital modes, managing contests, tracking awards and displaying propagation information.
That approach is important because a modern amateur station often involves several separate programs. A typical operator might have one application for logging, another for CAT control, another for FT8, another for DX Cluster spots and another for propagation information.
RadioLog attempts to bring much of that functionality into a single interface.
The current main screen combines the VFO and operating information with the logbook, QSO entry and other operational panels. The interface was substantially redesigned for version 4.0.0 and received additional layout and theme refinements in version 4.0.2.
The Interface Looks Excellent
One of the first things that caught our attention is the interface.
RadioLog does not look like an old Windows database application that has simply been kept alive for another decade. The current design uses a modern dark-console appearance with an operating panel, logbook and QSO entry integrated into the main workspace.
Version 4.0 introduced a completely redesigned interface, including an always-visible operation panel with VFO, CAT and S-meter information. The DX Cluster and Previous Contacts panels can also be docked or undocked. Version 4.0.2 subsequently refined the dark theme and fixed several layout issues.
For a piece of amateur-radio software, that matters.
A logging program is something many operators keep open throughout an operating session. A clean interface with the information we actually need visible at the same time can make a significant difference.
RadioLog appears to have been designed around that concept.
The Logbook
At the heart of RadioLog is, of course, the QSO log.
The main logbook displays contacts in a table while the QSO-entry panel provides the fields required to record a contact. RadioLog can automatically populate information when a callsign is entered, using either QRZ.com or HamQTH depending on the configured lookup service.
Typical fields include:
QSO Information | RadioLog |
|---|---|
Callsign | Yes |
UTC date/time | Yes |
Band | Yes |
Mode | Yes |
Frequency | Yes |
RST sent/received | Yes |
Operator name | Lookup |
Grid locator | Lookup |
Comments | Yes |
When CAT is connected, RadioLog can obtain the operating frequency, band and mode directly from the transceiver. That means an operator doesn’t necessarily have to enter the same information manually for every QSO.
That is exactly the sort of integration we want to see in a modern logging application.
QRZ.com and HamQTH Integration
Callsign lookup is another important part of the RadioLog workflow.
When a callsign is entered, RadioLog can query QRZ.com or HamQTH and automatically populate information such as the operator’s name and locator. There is also a bulk lookup facility for updating multiple existing QSOs.
There is an important distinction here.
QRZ.com automatic lookup requires a suitable QRZ XML subscription, while HamQTH provides a free lookup option according to the RadioLog documentation.
RadioLog also supports reciprocal synchronization with the QRZ.com Logbook. That is particularly interesting because it means QRZ isn’t simply being used as a callsign database; the local RadioLog log can synchronize QSOs with the online QRZ logbook.
ADIF, LoTW and eQSL
Interoperability is essential for logging software.
Nobody wants to spend years building a QSO database only to discover that moving to another application is difficult.
RadioLog supports ADIF import and export along with electronic QSL services including eQSL and LoTW. The current version also supports QRZ Logbook synchronization, while the RadioLog site lists Club Log and HRDLog among its supported logbook services.
The bulk-upload functionality is another useful feature. RadioLog can select multiple QSOs and upload them in batches rather than requiring every contact to be handled individually.
For an operator maintaining a substantial log, that could save considerable time.
CAT and Rig Control
This is where RadioLog starts becoming much more than a simple logging program.
RadioLog provides integrated CAT control and supports several approaches, including its own direct control, Hamlib-managed control and an external rigctld server. The documentation also describes native Icom CI-V support and integration with digital-mode applications.
The ability to keep frequency and mode synchronized between the radio and logbook is one of the most useful capabilities a logging application can provide.
RadioLog’s documentation also specifically addresses WSJT-X and JTDX integration, allowing digital-mode QSOs to be logged automatically.
A particularly interesting feature: Hamlib integration
RadioLog includes Hamlib rather than requiring the operator to install it separately. It can manage rigctld and provide a relay for digital-mode applications.
That could potentially simplify a station where several applications need access to the radio.
We would want to test this ourselves before making any claims about reliability, however. CAT configuration is one of those areas where documentation and actual operating experience aren’t always the same thing.
DX Cluster Integration
RadioLog also incorporates a DX Cluster directly into the operating environment.
DX spots can be displayed in the application and are colour-coded according to their status in the logbook, such as whether a station is new, already worked or confirmed. Operators can filter spots by relevant criteria and use the information directly from the operating interface.
This is a good example of where an integrated application can make sense.
Instead of moving between a logging application and a separate DX Cluster window, the operator can have the information available alongside the logbook and radio controls.
Digital Modes
RadioLog isn’t limited to traditional SSB and CW logging.
The software integrates with WSJT-X and JTDX and can automatically log digital-mode contacts. RadioLog also supports a range of digital voice modes, including DMR, C4FM, D-STAR, FreeDV and M17.
The digital-mode integration is particularly relevant because FT8 and related modes have changed the way many operators use their stations.
A modern logbook needs to be able to handle contacts generated by software rather than assuming every QSO is manually entered by the operator.
RadioLog appears to recognize that reality.
Contest Logging
Contest operators are another audience that RadioLog is attempting to address.
The application provides a separate contest log along with automatic scoring and Cabrillo and EDI export. The current documentation also references CQ-WW contest support.
That makes RadioLog considerably more ambitious than a basic station log.
Contest Requirement | RadioLog |
|---|---|
Separate contest logging | Yes |
Automatic scoring | Yes |
Cabrillo export | Yes |
EDI export | Yes |
HF contest support | Yes |
VHF contest support | Yes |
CQ-WW support | Yes |
Again, we would want actual contest use before evaluating how well this works under pressure.
Portable Operations: SOTA, POTA and WWFF
This is another feature that makes RadioLog stand out.
RadioLog provides a dedicated portable mode for activities including:
- SOTA
- POTA
- WWFF
/Poperations- CB/11m
The portable functionality has its own logging workflow rather than simply forcing the operator to treat every activation as a conventional home-station QSO.
For operators who regularly take their equipment into the field, that could be a major attraction.
The RTL-SDR Auxiliary Monitor
Perhaps the most unexpected feature is the integrated RTL-SDR auxiliary monitor.
RadioLog can use a compatible RTL-SDR as an auxiliary visual and audio monitoring device. That adds a completely different capability to what would otherwise be a conventional logging application.
This is particularly interesting from the Radio Hobbyist perspective because SDR and traditional amateur radio increasingly overlap.
We wouldn’t buy RadioLog specifically for this feature without testing the implementation, but it is certainly something that makes the software unusual.
Maps, Statistics and Awards
RadioLog also includes a collection of tools for analyzing the log.
The software provides:
- worldwide QSO mapping
- propagation information
- DXCC statistics
- band and mode statistics
- award tracking
- QSO history
The map can operate in either online or offline mode. The offline mode uses a map included with RadioLog, meaning the basic map functionality does not require an Internet connection.
The statistics panel provides information such as DXCC entities, continents, CQ zones, locators, confirmations and the operator’s most-used bands and modes.
For operators who enjoy watching their log develop over time, these features add considerable value.
Previous Contacts With a DX Station
One small feature that we particularly like conceptually is the Previous Contacts panel.
When entering a callsign, RadioLog can display previous contacts with that station. That provides useful context before saving a new QSO and can help avoid duplicate or unnecessary information.
This is the kind of feature that doesn’t necessarily appear on a marketing checklist but can make a logging application considerably nicer to use.
Automatic Backups
A logging application is only as good as its ability to protect the log.
RadioLog has an automatic database backup system with configurable backups on events including saving, ADIF import, periodically and when closing the application.
That is an important feature, although we would still recommend maintaining an independent backup of an important station log.
A local backup inside the same computer should never be considered the only copy of a valuable QSO database.
Online Log Publishing
RadioLog even includes an online-log publishing capability.
The documentation describes an FTP configuration and automatic generation of a radiolog.htm page that can be published online.
That is an interesting legacy-style feature that some operators may still appreciate, particularly those who like maintaining a public station log without relying entirely on a third-party service.
Installation and Windows Compatibility
RadioLog is specifically designed for Windows 10 and Windows 11 64-bit systems.
The current installer is intended to be self-contained, with dependencies included rather than requiring the operator to separately install Python or other runtime components.
There is one point prospective users should know before installing it.
The developer currently distributes RadioLog without a commercial code-signing certificate. Consequently, Windows SmartScreen may display an “Unknown publisher” warning during installation. The official RadioLog site specifically recommends downloading the software from its official website and provides a SHA-256 checksum for the current installer.
That does not automatically mean the software is unsafe, but it is something we should take seriously with any executable downloaded from the Internet.
What We Like About RadioLog
Based on the current feature set, there is a lot to like.
Strength | Why It Matters |
|---|---|
Free | Removes the cost barrier for experimentation |
Modern interface | Looks considerably more current than many traditional logging programs |
Integrated CAT | Reduces manual frequency and mode entry |
DX Cluster | Keeps spotting information inside the operating environment |
Digital modes | Supports modern FT8/FT4 workflows |
Contest support | Makes the software useful beyond casual logging |
Portable mode | Useful for SOTA, POTA and WWFF |
ADIF | Makes the log more portable |
QRZ synchronization | Useful for operators already using QRZ |
Statistics | Adds value beyond basic QSO storage |
RTL-SDR support | Unusual and potentially valuable |
Automatic backups | Important protection for the local database |
The combination is what makes RadioLog interesting.
There are plenty of amateur-radio logging programs. There are fewer that attempt to combine logging, CAT, DX Cluster, digital modes, contest operation, portable operation, mapping, statistics and SDR monitoring into one coherent application.
What We Don’t Know Yet
This is where we need to be careful.
We have not personally tested RadioLog, so there are several questions that only hands-on use can answer.
Question | Current Assessment |
|---|---|
How easy is initial configuration? | Looks straightforward, but untested |
How reliable is CAT? | Feature is documented, but untested |
How well does it work with WSJT-X? | Supported, but untested |
How stable is the application during long sessions? | Unknown |
How well does it handle a very large log? | Unknown |
How good is contest operation in practice? | Feature exists, but untested |
How useful is the RTL-SDR monitor? | Interesting feature, requires testing |
How easy is migration from another logger? | ADIF support is encouraging, but untested |
How good is portable operation? | Promising, but untested |
How does it compare with established logging software? | Requires hands-on comparison |
These aren’t necessarily weaknesses.
They are simply areas where we shouldn’t manufacture an opinion before actually using the software.
RadioLog Compared With a Basic Ham Logbook
The distinction becomes clearer when we look at what RadioLog is trying to accomplish.
Capability | Basic Logbook | RadioLog |
|---|---|---|
QSO database | Yes | Yes |
Manual QSO entry | Yes | Yes |
ADIF | Usually | Yes |
Callsign lookup | Sometimes | Yes |
CAT control | Sometimes | Yes |
DX Cluster | Rare | Yes |
Digital-mode integration | Rare | Yes |
Contest operation | Rare | Yes |
Portable operation | Rare | Yes |
QSO statistics | Basic | Extensive |
DXCC tracking | Sometimes | Yes |
Mapping | Sometimes | Yes |
Electronic QSL services | Sometimes | Yes |
RTL-SDR integration | Rare | Yes |
This is why calling RadioLog simply a “ham radio logbook” doesn’t really tell the whole story.
It is closer to a small amateur-radio operating suite with a logbook at its center.
Who Should Consider RadioLog?
RadioLog looks particularly interesting for several types of operators.
Operators building a new station
Someone starting from scratch could potentially get a substantial amount of station functionality from one free application.
Instead of immediately assembling a collection of separate programs, RadioLog provides logging, CAT, DX Cluster, digital-mode integration and other tools in one package.
Operators who want a modern interface
The current interface is one of RadioLog’s strongest attractions.
If older logging software has always felt dated or overly complicated, RadioLog is worth examining simply because its current design takes a different approach.
Digital-mode operators
WSJT-X and JTDX integration makes RadioLog particularly relevant to FT8 and FT4 operators.
Automatic logging and CAT synchronization are exactly the sort of capabilities we want in a modern digital-mode station.
Portable operators
The dedicated SOTA, POTA and WWFF support makes RadioLog worth investigating for operators who regularly operate away from their home station.
Experimenters
The combination of conventional amateur radio, CAT, DX Cluster functionality and an RTL-SDR auxiliary monitor makes RadioLog particularly interesting for technically minded operators.
Who Might Want Something Else?
RadioLog may not be the obvious choice for every operator.
Someone with an established logging workflow that already works perfectly may see little reason to change.
Likewise, operators who require very specialized contest, award or station-management features should compare RadioLog carefully against the software they currently use.
And because we have not yet tested it ourselves, we aren’t prepared to say that RadioLog is better than established alternatives.
That would require actual operating experience.
Our Verdict
RadioLog is one of those applications that becomes more interesting the further we look into it.
At first, it appears to be a free Windows ham-radio logbook. In reality, the current version is much more ambitious.
It combines QSO logging with CAT control, DX Cluster integration, digital-mode support, contest logging, portable operation, electronic QSL services, mapping, statistics, award tracking and an RTL-SDR auxiliary monitor. The current v4.0 series has also received substantial interface work, including the redesigned main screen and continuing usability fixes.
The fact that it is free makes it even more interesting.
There is essentially no financial barrier to downloading it and seeing whether it fits your station.
RadioLog Rating
Because we haven’t personally tested the software, we don’t think it would be honest to give it a conventional hands-on performance rating.
Instead, we would rate its potential based on the current feature set.
Category | Assessment |
|---|---|
Feature set | 9/10 |
Interface | 9/10 |
Integration potential | 9/10 |
Digital-mode support | 9/10 |
Portable operation | 9/10 |
Documentation | 8.5/10 |
Value | 10/10 |
Hands-on assessment | Not yet rated |
Overall: Highly Promising
RadioLog has enough going for it that we think it deserves serious attention from Windows-based amateur-radio operators.
The combination of a modern interface, extensive station integration and a completely free license is difficult to ignore.
The important caveat is that this is not yet our hands-on recommendation.
We haven’t connected a transceiver, imported a large ADIF file, run an FT8 session, participated in a contest or taken RadioLog into the field. Those are the next tests that would turn this from a promising software review into a genuine RadioLog evaluation.
For now, however, RadioLog looks like a very interesting piece of amateur-radio software — and one we intend to investigate more closely.
Where to Get RadioLog
RadioLog is currently available for Windows 10/11 64-bit from the developer’s website. The current release is v4.0.2.
For safety, we recommend obtaining the installer from the official RadioLog site rather than an unknown third-party download location. The DXZone listing is useful as a discovery and reference page, while the developer’s site provides the current release and installation information.
Final Thoughts
RadioLog has the appearance of a project that deserves more attention from the amateur-radio community.
What particularly interests us is not any single feature. It is the attempt to bring the entire operating workflow together: radio control, logging, DX spotting, digital modes, contests, portable operation and log analysis.
That is a much bigger proposition than simply replacing a paper logbook.
We haven’t tested RadioLog yet, so we’re deliberately stopping short of claims about reliability or day-to-day usability. But based on the current version and its documentation, this is definitely software we would put on our “worth investigating” list.
For a free Windows amateur-radio application, that is a very good place to start.
