About the Ham Radio Intelligence Portal

The Ham Radio Intelligence Portal (HRIP) is a free, live world map of amateur radio propagation. It automatically collects data from several public sources and renders it as real-time map layers, so operators can see band openings, current activity and propagation conditions at a glance.

What it shows

• DX Cluster — worldwide DX spots, one marker per spotted station, colored by how recent the spot is.
• Reverse Beacon Network — live CW/RTTY skimmer spots of active HF stations.
• VHF & up skeds — 144/432/1296 MHz and microwave schedules from the Telegram skedvhf channel.
• Ionospheric MUF — maximum usable frequency contours for HF propagation forecasting.
• Tropospheric ducting — VHF/UHF ducting forecast derived from GFS weather data.

HRIP is operated by IZ1KGA. It is useful for HF and VHF DXing, contesting, propagation study and band-opening monitoring. Open the live map or browse the data tables.
