General
- Many of the sites on the JORN Wikipedia entry can be found on RFMap:
The four JORN transmitter and receiver sites are:
- the Queensland transmitter at Longreach, Queensland, with 90 degree coverage
- the Queensland receiver at Stonehenge, Queensland, with 90 degree coverage
- the Western Australian transmitter at Leonora, Western Australia, with 180 degree coverage
- the Western Australian receiver at Laverton, Western Australia, with 180 degree coverage
The research and development transmitter and receiver sites are:
- the Alice Springs transmitter at Harts Range, Northern Territory, with 90 degree coverage
- the Alice Springs receiver at Mount Everard, Northern Territory, with 90 degree coverage
Assignments matching 4.591 MHz
- 4.591 MHz has been found while listening on HF. As it happens it is a registered assignment for many of the JORN stations:
