+ > The North Texas Microwave Society's propagation prediction service for amateur radio bands 10–241 GHz. Scores propagation conditions across CONUS using HRRR numerical weather prediction, sounding data, ITU-R atmospheric models, and calibration against 58,000+ recorded QSOs.
+
+ A real-time propagation prediction system for microwave amateur radio bands, built and operated by the North Texas Microwave Society.
+
+ ## Tools and maps
+
+ - [Propagation map](/map) — real-time CONUS propagation scores with 18-hour forecast overlay.
+ - [Weather map](/weather) — HRRR weather data overlay (temperature, dewpoint, refractivity, ducting).
+ - [Weather map (Canada)](/weather-ca) — HRDPS/RDPS-based weather for Canadian coverage.
+ - [Contact map](/contacts/map) — geographic view of 58,000+ recorded QSOs.
+ - [Path calculator](/path) — point-to-point propagation prediction between two locations.
+ - [EME calculator](/eme) — Earth-Moon-Earth communication prediction for 144–10 GHz.
+ - [Skew-T diagram](/skewt) — atmospheric sounding visualization from HRRR profiles and RAOB data.
+ - [Rover planner](/rover) — propagation heatmap with ranked drive-to candidates.
+ - [Rover locations](/rover-locations) — shared directory of rover-friendly parking spots.
+ - [Rover planning](/rover-planning) — planned rover missions and their paths.
+
+ ## Data
+
+ - [Algorithm documentation](/algo) — full scoring methodology, factor weights, ITU-R model references.
+ - [Contact database](/contacts) — 58,000+ historical QSOs used for calibration.
+ - [Beacon directory](/beacons) — microwave beacon listings across North America.
+
+ ## About
+
+ - [About](/about) — project background.
+ - [Privacy](/privacy) — data collection and usage policy.
+
+ ## API
+
+ - [API documentation](/docs/api) — REST API reference.
+ - [OpenAPI spec](/openapi.json) — machine-readable API description.
+ - [Contact map data](/api/contacts/map) — JSON dump of all map contacts.
