TropoDX is the ultimate real-time tropospheric propagation monitoring tool for amateur radio operators worldwide. FEATURES: - Real-time Tropospheric Index (0-100 scale) based on atmospheric conditions - 5-day propagation forecast with hourly updates - Regional propagation maps for Europe, North America (East/West), Asia, and Australia/Pacific - Push notifications for excellent DX conditions (Index 80+) - Advanced atmospheric parameters: K-Index, Refractivity, Temperature-Dew Point spread - Location-based weather data from anywhere in the world - Detailed DX distance estimates based on current conditions - Historical data tracking (last 48 readings) - Support for both Metric and Imperial units - Works on iPhone and iPad with landscape support PERFECT FOR: - VHF DXers (2m, 6m bands) - UHF DXers (70cm band) - Contest operators - EME operators checking for optimal conditions - Anyone interested in VHF/UHF propagation UNDERSTANDING THE INDEX: - 0-40: Poor - Normal conditions, local contacts only - 40-55: Fair - Slightly enhanced propagation - 55-70: Good - DX possible, 200-500 km range - 70-85: Very Good - Strong DX, 500-1000 km range - 85-100: Excellent - Extreme conditions, 1000+ km possible! The app calculates tropospheric conditions using atmospheric pressure, temperature, humidity, dew point, and refractivity to predict VHF/UHF radio wave propagation. When high-pressure systems create temperature inversions, radio signals can travel much farther than normal - and TropoDX helps you catch those moments! DATA SOURCES: - Real-time weather data from OpenWeatherMap - Regional propagation maps from DX Info Centre - Scientific calculations based on radio refractivity formulas Whether you're chasing grid squares, working DX contests, or just curious about propagation, TropoDX gives you the information you need to maximize your VHF/UHF operating. 73 and happy DXing!
