What counts as a ghost?

A documented station or service closure, supported by a dated recording and its provenance. Failed streams in the live radio directory are not evidence of closure. Frequencies shown belong to the linked surviving clips and are not a complete historical allocation list.

Markers use GeoNames city or regional reference points, not surveyed transmitter coordinates. Six sourced entries are published; wider coverage is still being researched. Sources checked 15 September 2026. Recordings stay at their original archives.
