About CQDX

What is CQDX?

CQDX aggregates live DX spots from multiple sources and correlates them with DXCC entity rarity rankings from ClubLog's Most Wanted list. It answers the question every DXer asks:

"What rare DX is on the air right now, that I can work, on which band and mode?"

Existing sites each do one thing. None of them correlate rarity, propagation, band/mode, and live spots together in a modern, accessible interface. CQDX does.

Data Sources

• PSKReporter — live digital mode spots (active now)
• Reverse Beacon Network — automated CW and digital skimmer spots (planned)
• Traditional DX Clusters — human-reported DX spots (planned)
• ClubLog Most Wanted — DXCC rarity rankings refreshed daily

Spots from all sources are normalized, deduplicated, and aggregated so you see a unified picture rather than duplicated data.

Public API

All data is available through a public REST API. Endpoints include:

• GET /api/v1/spots — paginated, filterable spot feed
• GET /api/v1/spots/live — Server-Sent Events stream
• GET /api/v1/entities — DXCC entities with rarity rankings
• GET /api/v1/entities/{dxcc} — entity detail
• GET /api/v1/stats — current activity summary

Rate limited to 60 requests/minute unauthenticated. API key access with higher limits coming soon.
