- Loran-C Transmitter, Shortwave relay station
What it is Filled
A facility housing transmitters and antennas that broadcast or relay radio signals, including broadcast transmitter sites for radio and television, shortwave relay stations serving international broadcasters, navigation transmitters such as former Loran-C stations, and telecommunications and time signal stations, often marked by tall masts or towers on high ground; transmitter stations are licensed, subject to radiation exposure limits, and many have been decommissioned as technologies change.
Why it exists Filled
Let an agent explain transmitter stations and their kinds, relay technical and regulatory aspects from public sources, describe notable stations and their history, and distinguish transmitter stations from studios and receiving stations.
Distinguishing features Filled
- High-power transmitters
- Antenna masts
- Licensed operation
- Technology transitions
What robots and AI may and may not do Filled
Must not
- Transmit on licensed frequencies or alter a station's output without authorisation.
- Interfere with or jam a broadcast, navigation or emergency transmission.
- Enter or climb a mast or antenna area, or advise others to, while transmitters are live.
- Present radio exposure claims about a site without measurements against the applicable limits.
Only with a human decision
- Any change to a station's transmission, power or antenna configuration.
- Shutting down a station that carries emergency information.
May
- Report a transmitter station's location, frequencies and licensed operator from the regulator's register.
- Monitor and report signal strength or outages for a station the agent is authorized to observe.
Moral aspects Filled
- Transmitter stations carry emergency warnings and navigation signals that lives depend on.
- Mast sites carry fall and radiofrequency exposure risks for workers, and local exposure fears deserve measured answers.
Who is affected
- Listeners and viewers who depend on the signal
- Site and mast workers
- Nearby residents
Owners Filled
Steward
The licensed broadcaster or site operator; the national communications regulator licenses it.
Master systems
- National spectrum licence registers

- Loran-C transmitter power: up to about 1 MW - peak
Recognition required Filled
- Facility with transmitters and antennas
- Broadcast sites, shortwave relay stations, Loran-C transmitters, telecom stations
- Studios produce programmes; receiving stations listen; cell towers are smaller sites
- Buildings with tall masts, towers or antenna arrays.
Capabilities and actions required Filled
- explain kinds and functions
- relay technical and regulatory aspects
- describe notable stations
- distinguish from studios and receivers
Hazards and failure modes required Filled
- Mast collapse and climbing hazards
- Interference
- Stale information on decommissioned stations
Standards and interfaces required Filled
- Spectrum licensing by national regulators
- ITU radio regulations
- Radiofrequency exposure limits such as ICNIRP
- Aviation obstacle marking rules for masts
Context of use required Filled
- Broadcasting and relaying radio signals.
- broadcast transmitter stations for AM, FM and television
- shortwave relay stations
- navigation transmitters such as Loran-C and eLoran
- time signal and VLF stations
- telecommunications and satellite uplink stations
- decommissioned and heritage transmitter sites
Sources Filled
- Wikidata item Q5367899: transmitter station - identity and sense of the item
- Wikipedia: Transmitter station - general description of the item
Open questions
- Should shortwave relay station and Loran-C be separate entries?
- How should regulatory sources be linked?
- The registry entry has merged aliases naming distinct station types; should they be split off?
