Sources: HFCC + EiBi shortwave schedule databases.

Description, as the server wrote it
Get current tropospheric ducting conditions for FM radio DX. Returns whether enhanced propagation (tropo) is active, the tropo score, anomaly count, and details of any stations being received beyond normal range. Tropo ducting allows FM signals to travel hundreds of miles beyond their normal coverage.

Why it is in this group
- The description's first verb is "get": a word for reading.
Description, as the server wrote it
Get detailed information for a specific NOAA Weather Radio station plus a coverage thumbnail showing handheld / portable / fixed reception contours from terrain-aware (ITM) propagation modelling. The 'stem' is the unique key like 'WXK86~162_550' (callsign plus frequency in kHz with underscore). Get stems from find_weather_radio results — each station has a 'key' or 'stem' field. Example: 'KIH26~162_550', 'WXK86~162_550'.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
