CRXCluster: Cloud-based Tools for Amateur Radio Operators

Demonstrates a cloud-based suite of tools for amateur radio operations, eliminating local software installation. The platform integrates a comprehensive logbook with import/export functionality, an eMap application displaying DX spots, user locations, and grayline data, alongside a dynamic band map derived from DX cluster information. It also provides a vQSL system for QSL management and a mailbox with QSO verification.

Users can access a Web DX cluster to monitor spots and DXCC status, or connect via Telnet using external programs like Logger32 or Ham Radio Deluxe. The cluster supports advanced spot filtering by QRG, spot call, spot from, and origin, with configurable mail alerts based on IARU zone filters.

Additional features include a real-time chat for skeds, azimuth/distance calculations from a user's QTH (with QRA locator), a search engine for spot and logbook databases, a band status matrix, and a propagation tool for MUF calculations, leveraging data from N0NBH.
