Overview

AI-generated overview

Lets an assistant look up FM, AM, shortwave, TV, amateur radio and weather radio frequency data for the US and some other countries.

What you can do
Offers 20 lookup tools for FM, AM, TV and international stations by city, ZIP code, callsign, frequency or format, with per-station power, antenna, owner and coverage-map details. It also covers shortwave schedules and live reception predictions, amateur repeaters and callsigns, NOAA weather radio, public safety systems, FEMA alerts, tropospheric ducting status and database statistics.
When to use it
Use it to look up broadcast, TV, repeater, weather radio or public safety frequencies in the US and some other countries, or to check shortwave reception, tropospheric conditions and FEMA alerts.
Requirements
Connects to a remote SSE endpoint; no local runtime, packages, account or API key are needed.

Installation

In SourceWeft

  1. Open dxtra Radio — Frequency Database in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.dxtra%2Fdxtra-radio/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

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; Wikipedia for owner/brand and format enrichment. US only.

Parameterslatlonqueryrequiredradius_miles

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'.

Parameterscallsignrequired

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, Classic Rock, Top 40, R&B, Alternative.

Parameterslatlonformatrequiredradius_miles

fm_format_list

List all available FM format/genre categories with station counts.

Takes no parameters.

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.

Parametersqueryrequiredradius_miles

am_station_detail

Get detailed AM station info including transmitter power, antenna pattern, groundwave coverage, and ownership. Example: 'WABC', 'KNX', 'WBBM'.

Parameterscallsignrequired

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 database. Propagation: VOACAP.

Parameterslatrequiredlonrequiredhour

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.

Parameterslatlonqueryrequiredradius_miles

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'.

Parameterscallsignrequired

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.

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' field. Example: 'W8MRC~146_7400'.
