dxtra Radio — Frequency Database

com.dxtra/dxtra-radio

Connects Claude to a radio frequency database covering 70,000+ AM, FM, TV, shortwave, ham, weather, and emergency alert stations across 15+ countries including the US, UK, Europe, Brazil, Australia, South Africa, Chile, Argentina, Thailand, and Malaysia. The underlying service computes terrain-aware coverage maps using Longley-Rice propagation modeling and provides real-time FEMA IPAWS emergency alerts updated every 5 minutes. Reach for this when you need to query station technical parameters, check frequency neighbors, analyze coverage patterns, or monitor active emergency alerts by location. The database includes FCC licensing data, transmitter coordinates, power levels, antenna configurations, and ownership information across multiple broadcast bands from AM clear channel to shortwave utility stations.
