The offices were located at Broadway House, Jamestown, whilst the station's broadcasts were radiated from a transmitter in St Paul's.
Radio St Helena also broadcast internationally on one day each year – on 11.0925 MHz shortwave – using the call-sign ZHH-50.
Many of the station's regular presenters took part in this event, known as "Radio St Helena Day", thereby enjoying the experience of broadcasting to audiences all around the world.
The company was replaced by the St Helena Broadcasting Corporation (SHBC), which was to be funded by the island's government.
SHBC was also to publish a weekly newspaper, and run three FM radio stations, one of them a relay of the BBC World Service.
