How to use it

Search within the selected dataset, or use “List all rows” to show the full table for that CSV. Once the results table is visible, click any heading to sort by site, service, frequency, power, height, or pattern availability.

DAB rows display the multiplex/service-oriented fields. FM/VHF rows display station, frequency, RDS, and separate HP/VP in-use and licensed power fields. AM/MF rows display station, frequency, EMRP, and aerial/site heights.

The map button opens an interactive Leaflet/OpenStreetMap view. The separate offline SVG map still plots the CSV latitude/longitude columns without using third-party map tiles.
