Marine radio

Navigation warnings and weather broadcasts

HF Safety communications

Charleville Radio and Wiluna Radio monitor distress calls on the frequencies below.

Please remember to limit the use of these frequencies to distress and safety situations.

Frequency (KHz) Purpose

4125
6215
8291

Distress, urgency, safety and calling only, 24 hours a day
12290 Distress, urgency and safety only
Monitored from 0700 to 1900 local time (0800 to 2000 during daylight saving)
4146

6227
8294

Safety working channels

The rule of thumb for high frequency radio is to use the higher frequencies during the day and the lower at night. The best frequency for the time of day is likely to be:

  • 8291 - during the day
  • 4125 - at night
  • 6215 - as the next choice for either day or night.

More accurate predictions can be found on the Australian Commonwealth Government IPS Radio and Space Service agency website by selecting:

  • Hourly Area Prediction charts (HAP charts) show the area covered by each frequency for that time of the day for locations in South Australian coastal waters by each of the Charleville or the Alice Springs HF radio sites.
  • Hourly Network Area Prediction charts (NAP charts) show the best frequency for that time of the day for locations in South Australian coastal waters used to call either Charleville Radio or Wiluna Radio.

These charts are updated on an hourly basis.

If your vessel is fitted with an HF marine radio it's important to check that these frequencies are available so you can access these distress and safety services.

Navigation warnings

Navigation warnings are broadcast twice daily on 8176 kHz by:.

  • Coast Radio Adelaide will broadcast warnings  for areas D and F, at 1255 and 1455 Central Standard Time (CST) ; 0325 and 0725 Universal Time Coordinated (UTC).
    They will also cover warnings for  Auscoast Area E, if time permits.
