Amateur Radio Has Changed
More software. More devices. More complexity.
Many operators no longer have one radio, one computer, and one logbook. They use desktop logbooks, mobile apps, contest software, POTA tools, remote stations, LoTW®, QRZ, and ADIF files from everywhere.
The result is fragmented operating history, duplicated effort, missed confirmations, and award progress that is harder to see than it should be.
Multiple Logbooks
Contacts spread across desktop, mobile, contest, and specialty logging applications.
Multiple Services
LoTW® and QRZ confirmations are valuable, but operators still have to remember to check.
Multiple Activities
POTA, contests, remote operation, FT8, and specialized apps all generate separate logs.
Multiple Goals
DXCC, WAS, grids, bands, and club activity all need a connected view of the data.
Why DxQSO Exists
The intelligent platform for modern amateur radio
DxQSO is not another logbook you have to switch to. It connects the logbook applications, QSL services, mobile devices, and community tools you already use — then understands your activity and tells you what's worth your time.
Bring it together
DX-TQSL signs for LoTW® exactly like the TQSL you already use, then uploads to DxQSO automatically in the background. We keep your QRZ logbook in two-way sync, and on mobile the Network Listener captures QSOs live from your logging software. Manual ADIF upload is available on every platform, too.
Keep it current
Continuously monitor LoTW® and QRZ so confirmations and award progress are updated without waiting for you to open a logbook and request a download.
Make it useful
Turn scattered logbook data into notifications, achievements, social activity, analytics, and future AI-powered operating guidance.

Continuous Monitoring
Your logbook works even when you are away
Many logbook applications can download LoTW® confirmations. The difference is that the operator usually has to open the application, request the download, wait for the sync, and then review what changed.
DxQSO continuously monitors LoTW® and QRZ in the background and notifies you when something important happens.

DX-TQSL
What is DX-TQSL?
Last updated June 2026 · 3 min read
DX-TQSL is a Windows and Mac application that replaces the ARRL's TQSL program while adding cloud backup and real-time logbook upload features. If you currently use TQSL to upload QSOs to LoTW®, DX-TQSL is a drop-in replacement — your existing logging application requires no changes whatsoever.
What DX-TQSL adds over standard TQSL
Real-time logbook upload — Every QSO your logging app sends to LoTW® is simultaneously uploaded to your DxQSO cloud repository.
Cloud certificate backup — Your callsign certificates are automatically backed up to your DxQSO account. If they're ever lost or you move to a new computer, they restore automatically.
Cloud station location backup — All your station location data is backed up and can be restored on any PC or Mac with just your DxQSO login.
Automatic updates — DX-TQSL updates itself automatically when new versions of TQSL are released by the ARRL, typically within two weeks.
No changes to your logging application are required. DX-TQSL installs in the same location as TQSL and uses the same filename. From your logging app's perspective, nothing has changed.
Supported operating systems
Windows 10 and 11
macOS 12 (Monterey) and later
DX-TQSL
Installing DX-TQSL on Windows
Last updated June 2026 · 4 min read

Important: You must log in to your DxQSO account from within DX-TQSL before using it. QSOs will not be uploaded to your cloud repository until you are logged in.
DX-TQSL
Installing DX-TQSL on Mac
Last updated June 2026 · 4 min read
DX-TQSL installs over your existing TQSL installation on macOS. Your current certificates, station locations, and TQSL preferences are preserved. The process takes about two minutes.
Before you begin: Quit your logging application and any open instance of TQSL before running the installer.
Installation steps
1
Log in to dxqso.net and go to Download → Download DX-TQSL. Select the macOS installer (.pkg file).
2
Open the downloaded .pkg file and follow the installer prompts. DX-TQSL installs to /Applications/TrustedQSL — the same location as your existing TQSL — so your logging apps keep working with no changes.
3
Open DX-TQSL from your Applications folder. The installer is signed and notarized by Apple, so it opens without any security overrides.
4
When DX-TQSL opens, click DxQSO Login / Register on the main screen and log in with your DxQSO account credentials. This links DX-TQSL to your account and triggers an automatic cloud backup of your certificates and station data.
Important: You must log in to your DxQSO account from within DX-TQSL before using it. QSOs will not be uploaded to your cloud repository until you are logged in.
If you don't have TQSL installed
If this is a fresh Mac with no prior TQSL installation, DX-TQSL will start with an empty certificate store. After logging in to your DxQSO account, your certificates and station locations will be automatically restored from your cloud backup — provided you have previously backed them up from another computer.
DX-TQSL
Logging In to DxQSO from DX-TQSL
Last updated June 2026 · 2 min read
You only need to log in to DxQSO from within DX-TQSL once. After that, DX-TQSL stays connected to your account automatically — even after restarts and updates.
How to log in
1
Open DX-TQSL on your PC or Mac.
2
Click the DxQSO Login / Register button on the main screen (or find it under the DxQSO Configuration tab).
3
Enter your DxQSO email address and password and click Login.
4
You will see a "Successfully Logged In!" confirmation. The DxQSO login button will now show your callsign or username.
What happens after login: DX-TQSL immediately backs up your certificates and station locations to your DxQSO account. Going forward, every QSO your logging application sends to LoTW® will also be uploaded to your DxQSO cloud repository in real time.
If you don't have a DxQSO account yet
Click the Register link on the login form inside DX-TQSL. This opens your web browser to the DxQSO account creation page. After creating your account, return to DX-TQSL and log in.
Logging out
You can log out of DxQSO from the DxQSO Configuration tab at any time. After logging out, QSOs will continue to be sent to LoTW® but will no longer be uploaded to your DxQSO repository until you log in again.
DX-TQSL
Managing Certificates
Last updated June 2026 · 3 min read
Callsign certificates are issued by the ARRL and are required to sign and upload QSOs to LoTW®. DX-TQSL automatically backs up your certificates to your DxQSO account and restores them if they are ever lost or you move to a new computer.
Viewing your certificates
Your installed callsign certificates are shown in the Callsign Certificates tab of DX-TQSL. Each certificate shows your callsign, the DXCC entity, and its expiry date.
You can also view and manage your cloud-backed certificates from the DxQSO website at Download → DX-TQSL Config Backup.
Automatic cloud backup
When you log in to DxQSO from DX-TQSL, your certificates are automatically backed up to your account. Backups are also created automatically whenever:
A new certificate is installed
A certificate is renewed or superseded
You manually trigger a backup from the DX-TQSL File menu
Automatic restore
If DX-TQSL detects that your certificate store is empty — for example after a system reinstall or on a new computer — it will automatically restore your most recent certificate backup from DxQSO after you log in. No manual action is required.
Manually backing up certificates
1
In DX-TQSL, click File → Upload to DxQSO: Backup Station Locations, Certificates and Preferences.
2
DX-TQSL will confirm the backup was successful.
Requesting a new certificate from ARRL
If you need a new certificate — for example for a new callsign or after your existing certificate expires — use the standard ARRL certificate request process from within DX-TQSL under Callsign Certificates → Request New Callsign Certificate. DX-TQSL will back up the new certificate automatically once it is installed.
Note: You do not need to export or save .tq6 files manually. DxQSO handles certificate backup and restore automatically once you are logged in.
DX-TQSL
Managing Station Locations
Last updated June 2026 · 3 min read
Station locations define where you are operating from and are required by LoTW® to sign QSOs correctly. Each location includes your callsign, DXCC entity, grid square, ITU zone, CQ zone, and other details. DX-TQSL backs up all your station locations to DxQSO automatically.
Viewing your station locations
Your station locations are listed in the Station Locations tab of DX-TQSL. You can also view and manage them from the DxQSO website under Profile → Station Locations.
Creating a new station location
1
In DX-TQSL, go to the Station Locations tab and click Add.
2
Work through the station location wizard, entering your callsign, DXCC entity, grid square, and operating zones.
3
Give the location a descriptive name (e.g. Home Station, POTA Field, Contest Remote).
4
Click Save. The new location is backed up to your DxQSO account automatically.
Station location types in DxQSO
DxQSO distinguishes between two types of station locations:
LoTW® Stations — locations that have a matching callsign certificate and can be used to sign QSOs for LoTW® upload.
DxQSO Stations — virtual stations used to organize your logbook within DxQSO. These do not require a certificate and are used for grouping QSOs from different operating activities (POTA activations, contest entries, remote setups, etc.).
Syncing station locations from DxQSO
If you have set up station locations on the DxQSO website, DX-TQSL can sync them to your local installation. Go to File → Restore from DxQSO to pull your latest station configuration from the cloud.
DX-TQSL
Backup & Restore
Last updated June 2026 · 3 min read
DX-TQSL automatically backs up your complete TQSL environment — callsign certificates, station locations, and preferences — to your DxQSO account every time something changes. You can also trigger a manual backup at any time, and restore any backup version from the DxQSO website.
Automatic backups
Backups happen automatically whenever:
You log in to DxQSO from DX-TQSL for the first time
A new certificate is installed or renewed
A station location is created or modified
You manually trigger a backup
Triggering a manual backup
1
In DX-TQSL, go to File → Upload to DxQSO: Backup Station Locations, Certificates and Preferences.
2
DX-TQSL will confirm the backup completed. You can view the backup in your DxQSO account under Download → DX-TQSL Config Backup.
Restoring your configuration
To restore your most recent backup — for example after a system reinstall or crash:
1
Install DX-TQSL on the PC or Mac (see Windows or Mac instructions).
2
Log in to your DxQSO account from DX-TQSL. Your certificates and station locations will restore automatically.
Restoring an older backup version
DxQSO keeps a history of all your configuration backups. To restore an older version:
1
Go to dxqso.net → Download → DX-TQSL Config Backup.
2
Find the backup version you want to restore and click Download. This downloads a .tbk backup file.
3
In DX-TQSL, go to File → Restore from DxQSO: Restore Station Locations, Certificates and Preferences and select the downloaded file.
DX-TQSL
Moving to a New Computer
Last updated June 2026 · 2 min read
One of the biggest advantages of DX-TQSL over standard TQSL is how easy it is to move to a new computer. There's no need to export .tq6 certificate files, no hunting through old email for certificate backups, and no risk of losing your station data. Your entire TQSL environment is stored in the cloud and restores automatically.
Setting up DX-TQSL on a new computer
1
On the new computer, go to dxqso.net → Download → Download DX-TQSL and download the installer for Windows or Mac.
2
Run the installer and follow the prompts.
3
Open DX-TQSL and click DxQSO Login / Register.
4
Log in with your DxQSO credentials. That's it. Your callsign certificates and station locations are automatically restored from your cloud backup.
No .tq6 files needed. DxQSO stores your certificates securely in the cloud. You never need to manually export or import certificate files when moving computers.
Setting up DX-TQSL on an additional computer
The same process works for adding DX-TQSL to a second or third computer — for example a laptop, a remote station PC, or a shack rebuild. Install DX-TQSL, log in to your DxQSO account, and your complete setup is restored automatically.
DX-TQSL
Updating DX-TQSL
Last updated June 2026 · 1 min read
DX-TQSL updates itself automatically. When a new version is available — either a DX-TQSL update or a new ARRL TQSL release — DX-TQSL will notify you and prompt you to update the next time you open it.
Automatic update checks
Each time DX-TQSL starts, it checks for available updates in the background. If an update is available you will see a notification at the top of the DX-TQSL window. Click Update Now to download and install it.
ARRL TQSL releases
When the ARRL releases a new version of TQSL, DX-TQSL is typically updated within two weeks. Your logging application does not need any changes — DX-TQSL handles the update transparently.
Manual update check
To check for updates manually, go to Help → Check for Updates in DX-TQSL.
Your data is safe during updates. Updates never affect your certificates, station locations, or DxQSO connection. Your cloud backup also means you can always restore if anything unexpected happens.
Your Logbook
Uploading ADIF Files
Last updated June 2026 · 3 min read
ADIF upload lets you import your logbook history into DxQSO from any logging application that can export ADIF format — which is virtually all of them. Use this to load historical QSOs, combine logs from multiple apps, or add QSOs from POTA activations, contests, or specialized tools.
How to upload an ADIF file
1
Export an ADIF file from your logging application. In most apps this is under File → Export → ADIF.
2
On dxqso.net, go to Logbook → ADIF Upload.
3
Click Choose File, select your ADIF file, and click Upload.
4
DxQSO processes the file in the background. You can monitor progress on the ADIF Upload page — large files may take a few minutes.
What happens to existing QSOs
DxQSO uses intelligent duplicate detection when processing ADIF uploads:
If a QSO in the file already exists in DxQSO, the existing record is updated with any new field data from the uploaded file.
If a QSO in the file does not exist, it is added as a new record.
No duplicates are created, even if you upload the same file multiple times.
POTA and contest logs: You can safely reload your entire POTA log after every activation, or re-upload a contest ADIF after corrections. DxQSO will update existing records without creating duplicates.
Supported file formats
.adi — standard ADIF format
.adif — extended ADIF format
Most logging applications export one of these formats. If your application exports in a different format (e.g. Cabrillo for contest logs), export as ADIF where possible or contact support.
Your Logbook
Real-Time Upload via DX-TQSL
Last updated June 2026 · 2 min read
Once DX-TQSL is installed and you're logged in to your DxQSO account, every QSO your logging application sends to LoTW® is simultaneously uploaded to your DxQSO cloud repository in real time — without any additional configuration or manual steps.
How it works
Your logging application communicates with DX-TQSL the same way it always has — DX-TQSL is a transparent replacement for TQSL. The difference is that when DX-TQSL receives a QSO to sign and upload to LoTW®, it also captures the full logbook record — all fields — and sends it to DxQSO at the same time.
From your logging app's perspective, nothing has changed. No configuration changes are needed in your logging application.
Compatible logging applications
Real-time upload works with any logging application that uses TQSL to upload to LoTW®, including:
Ham Radio Deluxe
N1MM Logger+
MacLogger / MacLoggerDX
SkookumLogger
N3FJP
World Radio League (WRL) — via ADIF upload
WSJT-X (via GridTracker)
Any other TQSL-compatible application
What if I don't use LoTW®?
DX-TQSL can upload QSOs to DxQSO even if you don't upload to LoTW®. In the DxQSO Configuration tab of DX-TQSL, you can set the LoTW® upload option to Do not upload to LoTW® while keeping DxQSO uploads active. QSOs will be sent to your cloud repository without being signed for LoTW®.
Your Logbook
Viewing & Searching QSOs
Last updated June 2026 · 2 min read
Your complete logbook is available at My QSOs → Summary on dxqso.net and from the DxQSO mobile app. QSOs are listed in reverse chronological order with key fields visible at a glance.
The QSO list
Each row in the QSO summary shows:
Contact date and time (displayed in your local timezone)
Callsign of the station worked
Band and frequency
Mode (FT8, SSB, CW, etc.)
DXCC entity
QSL status — LoTW® confirmed contacts are highlighted in green
Logbook source (which app uploaded the record)
Viewing QSO details
Click any QSO row to expand the full logbook detail view, which includes all fields uploaded from your logging application — grid square, RST, power, notes, contest exchange fields, and more. From the detail view you can also click the callsign to open the operator's QRZ.com profile.
Searching for a specific QSO
Use the search bar at the top of the QSO summary to search by callsign, DXCC entity name, or any other text field. Results update as you type.
Your Logbook
Filtering & Sorting
Last updated June 2026 · 2 min read
The filter panel in My QSOs → Summary lets you narrow your logbook view to exactly the QSOs you're looking for. Filters can be combined — for example, show all FT8 QSOs on 20m in the last 30 days that have been confirmed on LoTW®.
Available filters
Date range — filter by a start date, end date, or preset range (today, last 7 days, last 30 days, this year)
Callsign — show QSOs with a specific callsign or partial callsign
Band — filter by band (160m, 80m, 40m, 20m, 15m, 10m, etc.)
Mode — filter by mode (FT8, SSB, CW, RTTY, etc.)
DXCC entity — show all QSOs with a specific country or territory
QSL status — show only confirmed QSOs, only unconfirmed, or all
Station — filter by virtual station (Home, POTA, Contest, Remote, etc.)
Sorting
Click any column header in the QSO list to sort by that field. Click again to reverse the sort order. The default sort is by QSO date descending (most recent first).
Your Logbook
Duplicate Detection
Last updated June 2026 · 2 min read
DxQSO automatically detects and handles duplicate QSOs so you never need to worry about uploading the same log twice. Whether you're reloading a POTA activation log, re-uploading after corrections, or combining logs from multiple apps, the result is always one clean record per contact.
How duplicate detection works
When you upload an ADIF file or a QSO arrives via DX-TQSL, DxQSO checks whether a matching QSO already exists in your repository. A match is determined by:
Callsign of the contacted station
QSO date and time
Band
Mode
If a match is found, the existing record is updated with any new or changed field data from the incoming QSO. The logbook source field is updated to reflect the most recent upload. No duplicate record is created.
Practical examples
POTA: You can re-upload your entire POTA activation log after every activation without worrying about previous entries being duplicated.
Multiple apps: If you log in N1MM for contests and Ham Radio Deluxe for general operating, you can upload both without creating duplicates for the same QSO.
Corrections: Export and re-upload an ADIF after correcting a typo — DxQSO will update the affected records.

Last updated June 2026 · 2 min read
You can download your complete DxQSO logbook at any time from Download → Download Logbook Data. Fields are automatically mapped to the format of your target logging application.
How to download
1
Go to Download → Download Logbook Data on dxqso.net.
2
Select your target logbook application format from the dropdown. DxQSO automatically maps your logbook fields to the format expected by that application.
3
Optionally set a date range to download only QSOs from a specific period.
4
Click Download. An ADIF file will be generated and downloaded to your computer.
5
Import the downloaded file into your logging application using its standard ADIF import feature.
Supported download formats
DxQSO supports download in ADIF format compatible with all major logging applications including Ham Radio Deluxe, N1MM, MacLogger, and others. Field mappings are applied automatically based on the selected target application.
Your data is always yours. There is no lock-in with DxQSO — you can download your complete logbook at any time in standard ADIF format.
Your Logbook
Virtual Stations
Last updated June 2026 · 2 min read
Virtual stations let you organize your logbook into separate operating contexts — without physically separate logbooks. A virtual station might represent your home shack, a POTA activation at a specific park, a contest entry, or a remote station. All QSOs remain in your single consolidated logbook but can be viewed and filtered by station.
Use cases for virtual stations
POTA activations — create a virtual station for each park you activate (e.g. K-1234 Acadia). Filter your logbook by that station to see only QSOs from that activation.
Contest operating — create a virtual station per contest (e.g. CQ WW CW 2025). Upload your contest ADIF and assign it to that station.
Remote stations — separate QSOs from your home shack and your remote setup.
Multiple callsigns — if you operate under different callsigns (club call, portable call, etc.), organize by callsign station.
Creating a virtual station
Virtual stations can be created and managed from Profile → Station Locations on dxqso.net. When uploading an ADIF file, you can assign the QSOs to a specific virtual station during the upload process.
Your Logbook
Tagging QSOs
Last updated June 2026 · 2 min read
Tags let you add custom labels to QSOs for easy organization and filtering. Use tags to mark activations, operating events, special callsigns, or any operating context that matters to you.
Examples of useful tags
POTA-K-1234 — tag all QSOs from a specific park activation
Field Day 2025 — tag club Field Day QSOs
DX Expedition — tag contacts made during a DX trip
Mobile — tag QSOs made from a mobile setup
Rookie Roundup — tag contest contacts
Adding tags
Tags can be added when uploading an ADIF file — enter your tag in the Tag QSOs field on the ADIF Upload page and all QSOs in that upload will receive the tag. Tags can also be added or edited on individual QSOs from the QSO detail view.
Filtering by tag
Use the tag filter in the QSO summary to show only QSOs with a specific tag. This makes it easy to review all contacts from a particular activation or event without setting up virtual stations.
LoTW® & QSL
Connecting to LoTW®
Last updated June 2026 · 2 min read
Connecting your LoTW® account to DxQSO allows DxQSO to pull your QSL confirmations automatically on your chosen schedule. Your existing LoTW® QSO and QSL history is also imported during initial setup.

1
Go to My QSOs → LoTW® Sync on dxqso.net.
2
Enter your LoTW® username and password and click Save.
3
DxQSO will verify the credentials and begin importing your LoTW® QSO and QSL history in the background. This may take a few minutes for large logs.
Your credentials are secure. LoTW® credentials are stored encrypted and are used only to pull your QSL data from LoTW®. They are never shared or used for any other purpose.
What DxQSO imports from LoTW®
Your complete QSO history — all contacts you have uploaded to LoTW®
All QSL confirmations — contacts confirmed by both parties

Last updated June 2026 · 2 min read
DxQSO can sync with your QRZ Logbook account to import your QRZ QSOs, apply QRZ QSL confirmations to your logbook, and alert you when new QRZ QSLs arrive. QRZ data is merged with your LoTW® data into a single unified logbook view.
Connecting your QRZ account
1
Go to Profile → QRZ Configuration on dxqso.net.
2
Enter your QRZ API key. You can find your API key in your QRZ account under Logbook Settings → API Key. A QRZ XML Subscription or Logbook subscription is required to access the QRZ API.

QRZ vs LoTW® QSLs
DxQSO tracks LoTW® and QRZ confirmations separately. In the QSO detail view you can see which service confirmed each contact. Achievement tracking (DXCC, WAS, grids) accounts for confirmations from both sources.
LoTW® & QSL
QSL Arrival Alerts
Last updated June 2026 · 2 min read
DxQSO notifies you when new QSL confirmations arrive from LoTW® or QRZ — so you never have to manually check either service to see if a confirmation came through. Alerts are delivered as push notifications to your phone and optionally by email.
How QSL alerts work
When DxQSO runs its scheduled sync with LoTW® or QRZ and finds new confirmations, it applies them to your logbook and immediately sends you a notification. The notification includes the callsign, band, mode, and which service confirmed the contact.
Enabling QSL alerts
QSL arrival alerts are controlled from Profile → Notification Preferences:
LoTW® QSL received — push notification and/or email when new LoTW® confirmations arrive
QRZ QSL received — push notification and/or email when new QRZ confirmations arrive
Both can be toggled independently and each can be set to push only, email only, or both.
Timing: QSL alerts are sent as soon as DxQSO processes your scheduled sync. Member subscribers with daily sync receive alerts within 24 hours of a confirmation appearing on LoTW®.
LoTW® & QSL
Updating LoTW® Credentials
Last updated June 2026 · 1 min read
If you change your LoTW® password, you'll need to update it in DxQSO so that automatic QSL syncs can continue. DxQSO will notify you by email if it is unable to log in to LoTW® with your current credentials.
Updating your LoTW® password in DxQSO
1
Go to My QSOs → LoTW® Sync on dxqso.net.
2
Update your LoTW® username and/or password in the credentials fields.
3
Click Save. DxQSO will verify the new credentials immediately.
If you receive an email saying DxQSO cannot log in to LoTW®, update your credentials as soon as possible to prevent gaps in your QSL sync history.

DxSocial Community
What is DxSocial?
Last updated June 2026 · 2 min read
DxSocial is the community layer built into DxQSO. It connects you with other operators so you can share operating activity, celebrate achievements, keep tabs on what friends are working, and participate in friendly competition — all within the same platform as your logbook.
What you can do on DxSocial
Share achievements — post to your feed when you confirm a new DXCC entity, complete WAS, reach a new grid, or hit any personal milestone
Follow operators — follow friends and fellow operators to see their activity in your feed
See what's happening — view recent operating activity from people you follow, including POTA activations, contest entries, and DX chasing
Compete friendly — leaderboards rank you against other operators in DXCC, WAS, grids, and QSO totals
Join clubs — connect with your local or online ham radio club, share group activity, and coordinate events
Discuss and share — participate in forums, group discussions, shared files, and club blogs
Privacy
Your activity on DxSocial is only visible to operators you have approved as followers, or to members of clubs you have joined. You control exactly what is shared and with whom from Profile → Privacy Settings.
DxSocial Community
Your Activity Feed
Last updated June 2026 · 2 min read
The DxSocial activity feed shows a stream of posts from operators you follow — achievements earned, POTA activations completed, milestones hit, and anything they've chosen to share. Think of it as a Twitter-style feed specifically for ham radio operators.
What appears in your feed
Achievement posts from operators you follow (new DXCC confirmed, WAS completed, etc.)
POTA activation reports
Operating session highlights
Club announcements and event notices
Posts you've been mentioned in or replied to
Interacting with posts
You can like, comment on, and share posts from your feed. Commenting opens a conversation thread on the post where you can congratulate an operator on a milestone or discuss the contact.
Posting to your feed
You can post to your own feed manually from the DxSocial section of dxqso.net or the mobile app. DxQSO can also post automatically when you earn achievements — this is configured in Sharing Achievements.
DxSocial Community

New DXCC entity confirmed
New DXCC band confirmation
New US state confirmed

Clubs & Groups
Last updated June 2026 · 2 min read
DxSocial supports ham radio clubs and operating groups with a shared space for activity feeds, discussions, shared files, and event coordination. Club pages are separate from individual profiles and visible only to members.
What a club page includes
Activity feed — a shared feed of member operating activity and achievements
Discussion forums — threaded discussions on any topic the club chooses
Blog posts — longer form posts from club officers or members
Shared files — upload and share documents, contest logs, ADIF files, and other resources
Events — coordinate Field Day, POTA events, club contests, and operating weekends
Leaderboards — club-wide rankings for DXCC, WAS, grids, and QSO totals
Joining a club
Search for your club by name or callsign in the DxSocial search. If the club is open, you can join immediately. If it's invitation-only, a club officer will need to send you an invitation.
Creating a club page
Any DxQSO Member can create a club page. Go to DxSocial → Clubs → Create Club and fill in your club name, callsign, and description. You can then invite members and configure privacy settings.
DxSocial Community

Yes. Export an ADIF file from your logging application and upload it at Logbook → ADIF Upload. There is no limit on the number of QSOs you can upload.
What happens if I upload the same ADIF file twice?
DxQSO's duplicate detection handles this automatically. Existing QSOs are updated with the new data and no duplicates are created. You can safely re-upload at any time.
Can I download my logbook in ADIF format?
Yes. Go to Download → Download Logbook Data and select your target format. Your data is always yours and available for download at any time.
Which logbook applications can upload to DxQSO in real time?

What happens to my data if I cancel?
Your account reverts to Freemium. All your logbook data, settings, and DxSocial profile are retained. If you delete your account, all data is permanently removed within 30 days.

Contesting & Specialty Operating
🏁
Contest Operators
Contest logs usually live in separate files and never get merged into your main logbook. After the contest, upload your log to DxQSO and organize it into a dedicated virtual station — so every contact is preserved with its contest context and searchable alongside your full operating history.

Multiple Logging Applications
Many operators use different logging apps for different purposes — one for general HF operating, one for contests, one for VHF, one for a remote setup. DX-TQSL can receive uploads from multiple TQSL-compatible applications simultaneously in real time. Whether or not you use LoTW®, DX-TQSL allows any compatible app to upload QSOs to both LoTW® and DxQSO — or just DxQSO if you prefer.

Ready to simplify your logging?
Join thousands of operators who never miss a confirmation and always know the instant they hit a new milestone.
Give your ham radio application a cloud logbook backend in hours, not months. The DxQSO Ham Logbook Sync™ API lets any logging app upload QSOs in real time, download complete logbooks in JSON or ADIF, and sync incrementally — all through a simple REST API hosted on AWS API Gateway.
The DxQSO API handles the infrastructure — cloud storage, deduplication, LoTW® and QRZ sync, achievement tracking, and mobile access — so you can focus on building a great logging experience.
☁️
Instant Cloud Logbook
Add a cloud logbook repository to your application without building any backend infrastructure. DxQSO stores, deduplicates, and indexes every QSO you upload on behalf of your users.
⚡
Real-Time QSO Upload
Push QSOs to the cloud the moment they are logged. The POST /upload endpoint accepts up to 2,000 QSOs per request in JSON format or raw ADIF — whichever your application already produces.
🔄
Incremental Sync
The GET /logbook/download endpoint supports a Modified Since filter so your app can pull only QSOs changed since the last sync — keeping bandwidth and processing overhead minimal.
📄
JSON & ADIF Output
Download logbooks in JSON for in-app display or ADIF for file export. Full ADIF field support means every field your users have logged is preserved and retrievable.
📃
Pagination Built In
Large logbooks are paginated automatically using the X-Next-Token response header. Pass it back in the next request to retrieve the following page — no offset math, no missed records.
🔍
Filtering & Querying
Filter downloads by date range, band, and mode. Your application can surface relevant QSOs without pulling an entire logbook — reducing latency and payload size.
🔔
LoTW® & QRZ Sync Included
Every QSO uploaded through your application is automatically synced with LoTW® and QRZ Logbook according to the user's DxQSO preferences. QSL confirmations flow back without any additional work from your app.
🏆
Achievement Alerts for Your Users
QSOs uploaded through your application contribute to each user's DXCC, WAS, and grid tracking. When a new milestone is confirmed, DxQSO notifies the user — no extra work required from your application.
🔒
Simple Two-Token Auth
Authentication uses two Bearer tokens: a long-lived vendor token that identifies your application, and a per-user station token that the user generates from their DxQSO account. Simple, secure, and stateless.

No workflow changes. No replacing your favorite logging application. DxQSO fits into how you already operate — whether your app uploads to LoTW® automatically after every QSO or you manage uploads manually.
LoTW® uploads are individually confirmed by the DxQSO server
One thing that makes DxQSO unique is that the server confirms each individual LoTW® upload. Because LoTW® uses an older RESTful API, DX-TQSL and your logging application receive a confirmation for every contact successfully submitted to LoTW® — so you always know exactly which QSOs made it through, with no silent failures. QRZ uses a modern API key-based API which handles confirmation natively without requiring this additional verification step.
▶
How DX-TQSL works with all TQSL-compatible apps
DX-TQSL installs in the same location as the ARRL's TQSL application and uses the same filename — so every logging application that currently uses TQSL for LoTW® uploads automatically uses DX-TQSL instead. From the logging app's perspective, nothing has changed.
The key difference is when each application calls TQSL. Some apps call it automatically after every QSO for a real-time experience; others require the user to manually select QSOs and trigger an upload. Both approaches work identically with DX-TQSL.
Member subscribers can use DxQSO's server-based LoTW® upload: QSOs uploaded to DxQSO are gathered and forwarded to LoTW® in an optimized batch by the DxQSO server — reducing LoTW® load and improving reliability for high-volume operators. Freemium users upload directly to LoTW® via DX-TQSL as normal.
Automatic upload after every QSO
These applications call DX-TQSL automatically after each QSO is logged. Your LoTW® and DxQSO cloud repository are updated immediately — no manual action required.
🍎
MacLoggerDX
Auto per-QSO · DX-TQSL
MacLoggerDX for macOS calls DX-TQSL automatically after each QSO is logged. Every contact uploads to LoTW® and your DxQSO cloud repository in real time as you operate — no manual upload steps required.
🗺️
GridTracker
Auto per-QSO · DX-TQSL
GridTracker calls DX-TQSL after every QSO logged, uploading each contact to LoTW® and DxQSO in real time. In GridTracker setup, point the TQSL application path to your DX-TQSL installation. FT8, FT4, and other digital mode contacts appear in your cloud logbook the moment they are made.
Manual LoTW® upload via DX-TQSL
These applications require the user to select QSOs and manually trigger an upload to LoTW®. DX-TQSL works identically to TQSL in this workflow — when you upload to LoTW®, DxQSO receives the same QSOs at the same time. For DxQSO-only upload without LoTW®, use the ADIF upload method below.
💻
Ham Radio Deluxe
Manual · DX-TQSL
In Ham Radio Deluxe, you select QSOs and click Upload to LoTW® to trigger a TQSL upload. With DX-TQSL installed, those same QSOs are simultaneously uploaded to your DxQSO cloud repository. To load your full logbook history into DxQSO, do a one-time ADIF export and upload via the web.
🏁
N1MM Logger+
ADIF Upload
N1MM uploads to LoTW® via a manual process — users select QSOs and trigger the upload. For DxQSO, export your N1MM log as an ADIF file and upload it at Logbook → ADIF Upload. You can export and upload your full log every time — DxQSO's duplicate detection handles it cleanly.
📋
N3FJP Software
ADIF Upload
N3FJP applications require a manual upload step to send QSOs to LoTW®. For DxQSO integration, export your N3FJP log as ADIF and upload it via the DxQSO web interface or mobile app. Your full N3FJP logbook data — all fields — is preserved.
🖥️
SkookumLogger
Manual · DX-TQSL
SkookumLogger for Mac uses a manual Upload to LoTW® workflow via TQSL. With DX-TQSL in place, those uploads also reach your DxQSO cloud repository. Alternatively, export an ADIF file and upload directly for DxQSO-only sync.
🌐
World Radio League (WRL)
ADIF Upload
World Radio League (WRL) provides ADIF export which can be imported directly into DxQSO via the web interface at Logbook → ADIF Upload. Export your WRL log and upload the full file — DxQSO's duplicate detection keeps everything clean on re-uploads.
Real-Time via DxQSO Mobile App N1MM Listener
Some mobile and tablet applications broadcast QSO data as N1MM-style UDP packets over the local network. The DxQSO mobile app includes an N1MM Listener that receives these packets and uploads each QSO to your cloud repository in real time. No desktop or ADIF file needed.
How to enable: Open the DxQSO mobile app, go to Settings → N1MM Listener and enable it. Configure your logging app to broadcast QSO packets to the IP address of your phone or tablet on port 12060. QSOs uploaded via this method are forwarded to LoTW® and QRZ according to your DxQSO settings.
SmartSDR
N1MM UDP Listener
SmartSDR for iOS and Android — created by Marcus Roskosch — supports N1MM-style UDP packet broadcasting. Enable the DxQSO mobile app N1MM Listener on the same local network and every SmartSDR contact uploads to your cloud repository in real time as you log it.
SDR Control & Roskosch Apps
N1MM UDP Listener
Marcus Roskosch is the developer of SmartSDR and a suite of similar SDR and logbook applications including SDR Control. All apps in this family broadcast N1MM-style UDP packets and integrate seamlessly with the DxQSO mobile app N1MM Listener for real-time QSO upload.
Any N1MM UDP-compatible app
N1MM UDP Listener
Any logging application that broadcasts N1MM-style QSO packets over UDP on the local network — including N1MM Logger+ itself — can upload QSOs to DxQSO in real time using the DxQSO mobile app N1MM Listener.
Mobile App — Export & Upload
Mobile logging apps that don't support direct DX-TQSL or UDP broadcasting can export their log to a local ADIF file on your phone and upload it directly to DxQSO using the mobile app — no computer required. Upload your full log every time; duplicate detection keeps everything clean.
🎯
Ham2K Polo
Mobile Export
Ham2K Polo is widely used for POTA and general mobile operating. Export your Polo log to a local ADIF file on your phone and upload it to DxQSO via the mobile app. Upload your entire activation log every time — DxQSO handles duplicates automatically. QSOs are forwarded to LoTW® and QRZ per your settings.
📋
HamRS
Mobile Export
HamRS is popular for POTA activations on iOS and Android. Export your HamRS log as ADIF and upload directly to DxQSO from your phone. Your contacts are added to your cloud logbook and forwarded to LoTW® and QRZ — no desktop needed at any point.
📲
Any mobile ADIF-exporting app
Mobile Export
Any mobile or tablet logging application that can export an ADIF file works with DxQSO. Export your full log — the entire file every time is fine — and upload it from the DxQSO mobile app. Duplicate detection ensures a clean result on every upload.
Web ADIF Upload — Works With Everything
Any application that exports ADIF can send data to DxQSO via the web upload at Logbook → ADIF Upload. No software installation required. Export your full log every time — DxQSO deduplicates automatically, updating existing records and adding new ones.
📶
WSJT-X
ADIF Upload
WSJT-X maintains an ADIF log file that updates automatically as QSOs are made. Upload this file periodically via the DxQSO web interface or mobile app. For real-time per-QSO upload, use GridTracker (see above) — GridTracker reads from WSJT-X and calls DX-TQSL after each QSO. Both approaches bring your FT8, FT4, and WSPR contacts into your central logbook.
✉️
Winlink
ADIF Upload
Winlink saves a log of all sessions in its local logs folder as an ADI file. Upload that file to DxQSO via the web interface whenever you want to add your Winlink contacts to your cloud logbook. Your Winlink contacts appear alongside all other QSOs in your consolidated operating history.
📠
VarAC

Don't see your app listed?
DxQSO works with virtually every ham radio logging application through one of two universal methods:
📡 It uses TQSL to upload to LoTW®
If your logging application already uses the ARRL's TQSL to upload QSOs to LoTW®, it works with DX-TQSL — no exceptions. DX-TQSL is a transparent replacement that installs in the same location. Your app never knows the difference, and every LoTW® upload also goes to your DxQSO cloud repository automatically.
📄 It can export an ADIF file
ADIF is the universal ham radio data standard — virtually every logging application ever written can export it. Export your log and upload it at Logbook → ADIF Upload on dxqso.net or via the mobile app. Upload your full log every time — DxQSO's duplicate detection makes it safe to re-upload freely.
If neither method fits your workflow, contact us or check our Developer API — we're always happy to discuss tighter integrations with application developers.
Ready to connect your logging setup?
Download DX-TQSL and get started in minutes — or upload your first ADIF file right now with no software to install.
DX-TQSL replaces the ARRL's TQSL on your PC or Mac — keeping everything that works about TQSL while adding cloud backup, web-based certificate management, real-time QSO upload to DxQSO, and effortless setup on any computer. Whether you use LoTW® or not, DX-TQSL is your connection to the DxQSO cloud.
Free download · Activates with a free DxQSO account — sign up here or from inside DX-TQSL
What is DX-TQSL?
TQSL — but connected to the cloud
DX-TQSL installs in exactly the same location as the ARRL's TQSL and uses the same filename. Every logging application that currently uses TQSL works with DX-TQSL without any changes — your existing workflow is completely preserved.
The difference is everything behind the scenes: your certificates and station data are backed up to the cloud, every QSO is uploaded to your DxQSO repository in real time, and you can restore your complete TQSL environment on any PC or Mac in minutes.
LoTW® Users
DX-TQSL uploads to both LoTW® and DxQSO simultaneously. Every QSO your logging app sends to LoTW® also goes to your cloud logbook.
☁️
Non-LoTW® Users
Don't use LoTW®? DX-TQSL can upload QSOs directly to DxQSO only. Your logging app still calls DX-TQSL the same way — no changes needed.
LoTW® uploads individually confirmed
Because LoTW® uses an older RESTful API, DX-TQSL receives a server confirmation for each individual QSO submitted to LoTW® — so you always know exactly which QSOs made it through.
Everything DX-TQSL does for you
All the benefits, automatically
Cloud Certificate Backup
Your callsign certificates are automatically backed up to your DxQSO account the moment you log in. If they're ever lost — after a system reinstall, a crashed drive, or a new computer — they restore automatically. No hunting for .tq6 files, no re-requesting certificates from the ARRL.
Cloud Station Location Backup
All your station locations — with their DXCC entity, grid square, ITU zone, CQ zone, and all other fields — are backed up to the cloud automatically. Your full station configuration is always safe and ready to restore.
Full TQSL Environment Backup
Beyond certificates and stations, DX-TQSL backs up your complete TQSL environment including preferences and configuration data. Every backup is timestamped and stored in your DxQSO account — restore the latest version automatically, or pick any previous version from the web.
Manage Certificates & Stations from the Web
View and manage your callsign certificates and station locations directly from the DxQSO website — no need to open the DX-TQSL desktop application. Check what certificates you have, which stations are active, and when backups were last made, from any device.
Inactivate Stations
As your station setup evolves, old station locations for past events, contest activations, or previous operating environments can be marked as inactive. Inactive stations remain in your records for historical reference but are hidden from your active station list — keeping your setup clean and organized without losing any data.
Tag Your QSOs
DX-TQSL can tag every QSO it uploads with custom information about your operating context — a POTA activation reference, contest name, remote station identifier, or any label that means something to you. Tags travel with your QSO records into DxQSO and can be used to filter and organize your logbook.
Effortless Setup on Any PC or Mac
Moving to a new computer? Setting up an additional station PC? Install DX-TQSL, log in to your DxQSO account, and your complete TQSL environment — certificates, stations, and preferences — restores automatically. No manual certificate exports, no backup files to track down. Just your login.
Automatic Backup on Every Change
DX-TQSL backs up your environment automatically whenever something changes — a new certificate is installed, a station location is created or modified, or you log in for the first time on a new computer. You never have to think about backup; it happens in the background every time.
Real-Time QSO Upload to DxQSO
Every QSO your logging application sends through DX-TQSL is uploaded to your DxQSO cloud repository at the same time — in full, with all logbook fields, not just the fields required by LoTW®. Your cloud logbook stays in sync with your local log automatically.
Automatic Updates
DX-TQSL checks for updates automatically and notifies you when a new version is available — whether it's a DX-TQSL feature update or a new ARRL TQSL release. Updates are typically available within two weeks of any ARRL TQSL release. Your environment and data are never affected by updates.
Fully Compatible With TQSL
DX-TQSL is 100% compatible with every TQSL-compatible logging application. Ham Radio Deluxe, N1MM Logger+, MacLoggerDX, GridTracker, SkookumLogger, N3FJP, and every other app that works with TQSL works with DX-TQSL — with no changes required. World Radio League (WRL) users can export ADIF and upload directly to DxQSO via the web.

N1MM UDP Listener — Real-Time Upload

AI insights into your own operating — and your friends'
DxQSO is building an AI co-pilot that understands your logbook history, your confirmed QSL achievements, and what you're working right now — and turns it into personal, natural-language recommendations: the awards within your reach, what to work next, and where your best opportunities are. It also keeps an eye on your friends and club, surfacing what they're doing on the air that you can still jump in on.
✦Personal award guidance — "You're 3 states from 5-Band WAS — 20m still needs AK, DE, and WY, and 20m has been open to them this week"
✦What to work next — reads your logbook history, confirmed QSLs, and current on-air activity to point you at your best opportunity right now
✦Milestone nudges — "You just confirmed your 100th entity on 40m — 40m DXCC is now only 12 away"
✦Jump in with friends — "K3ABC is working a rare entity on 15m right now that you still need — here's the frequency"
✦Community highlights — natural-language summaries of what your friends and club have been doing on the air
