find_fm_stations | Find FM radio stations by city name, ZIP code, callsign, frequency,
format/genre (e.g. 'country', 'rock', 'jazz'), or network name.
Examples: 'Nashville', '90210', 'WFMT', '101.1', 'country near Austin',
'NPR near Boston'. Returns station list with frequency, callsign,
city, format, and signal strength data.
Source: FCC LMS (Licensing and Management System) for station data;
params: query*, radius_miles, lat, lon |
fm_station_detail | Get detailed information for a specific FM station by callsign.
Returns frequency, power, antenna height, format, owner, website,
location, and a coverage-map thumbnail image.
Example: 'WFMT', 'KPBS-FM', 'CIRA-FM'. params: callsign* |
fm_stations_by_format | Find FM stations by format/genre category.
Use this when you only have a format in mind and want to browse all
stations of that format. Use find_fm_stations instead if you have a
city or callsign — its query parameter also accepts format keywords.
Available formats: Country, Rock, Christian, Adult Contemporary,
Hip Hop, Classical, Jazz, News/Talk, Sports, Spanish, Public Radio, params: format*, lat, lon, radius_miles |
fm_format_list | List all available FM format/genre categories with station counts. params: none |
find_am_stations | Find AM radio stations by city, ZIP code, callsign, frequency,
or state. Includes daytime and nighttime coverage data with
Longley-Rice terrain-aware propagation modeling.
Examples: 'KNX', '1010', 'New York', 'CA'.
Source: FCC CDBS (Consolidated Database System). US only. params: query*, radius_miles |
am_station_detail | Get detailed AM station info including transmitter power,
antenna pattern, groundwave coverage, and ownership.
Example: 'WABC', 'KNX', 'WBBM'. params: callsign* |
shortwave_live | Find shortwave broadcasts receivable at a location right now
(or at a specific UTC hour). Uses VOACAP propagation modeling to
predict which broadcasts can actually be heard, not just what's
scheduled. Returns frequency, broadcaster, language, target area,
and predicted signal strength.
Schedule sources: HFCC (High Frequency Coordination Conference)
and EiBi shortwave databa params: lat*, lon*, hour |
shortwave_search | Search the shortwave schedule database. Returns SCHEDULED broadcasts
(what's listed in the operator schedules) — not what's actually receivable
at a location right now. For "what can I hear from here", use shortwave_live
instead, which factors in VOACAP propagation prediction.
Examples: '9330', 'BBC', 'Radio Havana', 'Spanish', 'Africa'.
Sources: HFCC + EiBi shortwave schedule params: query* |
find_tv_stations | Find TV stations by city, ZIP code, callsign, channel number,
or network name. Returns coverage data with terrain-aware modeling.
Examples: 'WABC', 'NBC near Chicago', '7', '10001'.
Source: FCC TV Query (full-power DTV stations). US only. params: query*, radius_miles, lat, lon |
tv_station_detail | Get detailed information for a specific TV station by callsign,
including channel, network, ERP, antenna height, and a coverage-map
thumbnail image (Longley-Rice terrain-aware heatmap).
Example: 'WABC', 'KCBS', 'WGN-TV'. params: callsign* |
find_repeaters | Find amateur radio repeaters near a location.
Optional filters: band ('2m', '70cm', '6m', '10m', '1.25m'),
mode ('FM', 'DMR', 'D-STAR', 'Fusion', 'P25', 'NXDN').
Returns frequency, offset, tone, callsign, and coverage.
Sources: ARD (Amateur Repeater Directory), RadioID.net (DMR),
BrandMeister network, and Yaesu WIRES-X. params: lat*, lon*, radius_km, band, mode |
repeater_detail | Get detailed information for a specific amateur radio repeater
plus a coverage thumbnail showing handheld / mobile / yagi reception
contours from terrain-aware (ITM) propagation modelling.
The 'stem' is the unique repeater key like 'KO4QJC~433_9000' (callsign
plus frequency in kHz with underscore). Get stems from find_repeaters
results — each repeater has a 'key' or 'stem' fiel params: stem* |
find_weather_radio | Find NOAA Weather Radio (NWR) stations near a location.
Returns frequency, callsign, transmitter location, and coverage area.
NWR broadcasts on 162.400-162.550 MHz.
Source: NOAA National Weather Service (weather.gov NWR transmitter
list). params: lat*, lon*, radius_miles |
weather_radio_detail | 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 params: stem* |
find_public_safety | Find public safety radio systems (police, fire, EMS, sheriff, transit,
hospital) near a US location. Returns agency name, system type
(conventional / trunked / encrypted), frequency or talkgroup, and
coverage data with terrain-aware modeling.
Source: FCC Universal Licensing System (ULS) Part 90 — Land Mobile
Private archive (l_LMpriv). US only. params: lat*, lon*, radius_miles |
emergency_alerts | Get current FEMA IPAWS emergency alerts (Integrated Public Alert
and Warning System). Returns active alerts including type, severity,
area, and instructions. Updated in real-time. params: none |
tropo_status | 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. params: none |
find_international_stations | Find radio stations in countries outside the USA.
Supported country codes: UK / GB (United Kingdom), EU (Europe — specify
country with query like 'Germany', 'France' or 'SE'), AU (Australia),
BR (Brazil), ZA (South Africa), CL (Chile), AR (Argentina),
TH (Thailand), MY (Malaysia), SG (Singapore), BN (Brunei),
VN (Vietnam), TW (Taiwan), RU (Russia), NZ (New Zealand),
JP (Jap params: country_code*, query |
ham_callsign_lookup | Look up an amateur radio operator by callsign.
Returns name, address, license class, grant date, and grid square.
