THE WORLD
IS CALLING.
One place for your DX contacts, beautifully designed eQSL cards and worldwide division progress. Built for Delta Tango operators — and everyone who enjoys the magic of radio.
Your DX command centre
Useful tools designed to work together, from that first contact to a new division milestone.
Your private contact logbook still stays in this browser. The separate, optional DX Proof archive uses a member account and shared server storage for evidence you choose to submit. Export your logbook backup regularly.

Browse HQ announcements, approved DX proofs and recent radio headlines from one place.

Turn a logged contact into a Delta Tango-styled confirmation card. Download it as a PNG image or printable vector SVG.

DX Milestones.
Track distinct divisions worked and your confirmed contacts. Download a personal achievement certificate when you reach a milestone.
Worked divisions awards

DX Proof Archive.
The 11-metre contacts behind the callsigns. Share your QSLs, see community evidence and build a personal confirmed-division score.
Evidence from around the world
Public entries have been reviewed by a site administrator. Review does not independently authenticate a QSO or a callsign.
Submit a new proof
Upload a cropped QSL-card image, activation photograph or other radio evidence. Remove GPS/EXIF location metadata before upload. Submissions stay private until reviewed by an administrator.
How Delta Tango proofing works
- Log your contact in your private DX logbook, or enter it here.
- Submit supporting evidence such as a received QSL.
- Administrator review checks suitability before publication.
- Build your country score from reviewed Direct QSL entries for different current divisions.

This system records evidence and moderation status; it cannot guarantee an on-air contact was genuine. It is independent of DXProof.com.
Country / division scores
Distinct current divisions backed by approved Direct QSL submissions. Historical/deleted entries and unconfirmed QSOs do not contribute.

Gaps in our archive
Divisions below do not yet have a public proof here. This is an archive coverage list, not a claim they are the world's most wanted.
Archive account
Separate from your existing Delta Tango group membership login. Registration is self-declared; a callsign alone does not confirm membership.
Signed in
You can submit proofs and manage your uploads.
Built with privacy in mind
Your private logbook remains on your device. Only the proof details and image that you deliberately submit are sent to the server.
The group administrator can approve, reject or remove uploaded evidence. Use a unique password. Site owners should maintain private backups of the server's data directory.
No existing Delta Tango membership or payment records are imported or changed.
Submissions awaiting approval
Radio Tools.
Handy station calculations and reliable external resources for the 11-metre DX operator.
Antenna lengths
Starting-point dimensions for wire antennas. Trim and check with an antenna analyser; mounting and surroundings change resonance.
Wire estimates include about 5% end-effect shortening (71.5 / f MHz for quarter wave).
Universal time
Standard QSO details
Record the date and time in UTC rather than local time, especially around daylight saving changes.
Live DX & propagation resources
This site does not show live values itself; these buttons open third-party data providers. Opening a page is not a guarantee a DX path is available.
The DX division system and logbook are for reference and record keeping; they do not confer radio privileges. Check current local frequency allocations and equipment rules before transmitting. In the UK, freeband frequencies outside authorised CB channels are not made lawful by using a DX callsign.
