Not just DX information.

DX Caliber brings together live radio activity, geographic visualization, and your operating history to help you recognize the contacts that matter.

01Interactive DX Map

02DXCC Intelligence

Know what you need.

DX Caliber compares incoming activity with your imported ADIF logbook, turning a DX spot into your next opportunity. See the entities, bands, and modes you still need without losing sight of what you have already achieved.

NEW DXCCNEW BAND SLOTNEW MODE SLOT

New DXCC: an entity you have not worked yet.
New band slot: a familiar entity on a band you have not worked.
New mode slot: a chance to add a new award mode group.
ADIF logbook integration
Intelligent opportunity prioritization

Worked and confirmed status stay distinct. Exact operating modes remain visible alongside award mode groups.

03Multiple DX Intelligence Sources

One picture. Multiple perspectives.

Combine information from DX Cluster networks, Reverse Beacon Network skimmers, digital-mode decodes, and reception reports into a unified view of amateur-radio activity.

Reverse Beacon Network (RBN)
WS Suite / WSJT-X local decodes
PSKReporter reception information
Consolidated station activity

Each source contributes a different observation: cluster spots report activity, skimmers detect signals, local decodes show what your station hears, and PSKReporter reports reception. Available information depends on the sources you enable and connect; reception alone does not indicate QSO availability.

04Your Logbook, Your Opportunities

Your operating history changes everything.

Your logbook provides the context that transforms an ordinary DX spot into a meaningful opportunity. DX Caliber uses your contact history to identify stations and entities worth your attention.

CLUBS / VIPs · THE PEOPLE YOU WANT TO HEAR

Keep your people
in the picture.

A familiar callsign can be just as rewarding as a new entity. Bring your clubs and personal VIPs into your station view, and recognize the people you want to work.

Your clubs. Your VIPs.

Add club rosters to easily identify active club members. Add individual callsigns as personal VIPs, so you can follow the people who matter to you.

Find them in the spots.

See club-member and VIP activity from DX Cluster and RBN spots, alongside the rest of your DX activity.

Know when you hear them.

Check live decodes from WSJT-X, WS Suite, and JTDX against your club and VIP lists to recognize matching callsigns as your station hears them.

Recognize the affiliation.

Club badges make membership easy to identify at a glance, connecting a callsign with its club without searching through your lists.

ANTENNA ROTATOR · YOUR NEXT DIRECTION

Point your antenna.
Keep your bearing.

Bring antenna control into your station view. See your current bearing, rotate toward a selected station, or enter a target heading—all with a clear view of where your antenna is pointing.

Support for Yaesu, Hy-Gain, microHAM ARCO, Green Heron, and Hamlib NET rotctld.
Customize bearing headings with named presets for your favorite directions.
Keep the bearing indicator visible over other windows with the “Always on top” option.
