HF Radio Communications

To contact the RFDS by HF radio you will need an HF transceiver fitted with RFDS frequencies for the area of operations you need, to talk to us. Transceivers are available from a number of suppliers who can be found in the yellow pages under ‘radio’.

How to contact the RFDS using the Emergency Call Facility

An emergency call is when you may need medical assistance from an RFDS Doctor

Select the appropriate frequency for the Base you wish to contact, and then transmit the Emergency call by pushing and holding the Emergency Call button on the radio for at least 20 seconds. Newer model radios have a timer that allows you to press the button for a few seconds and then let go and the timer will activate for a period of time.
The RFDS system will respond within a minute if our equipment has detected the call. It takes our system 10 seconds of continuous emergency tone monitoring before it activates.
If you do not get a response, select another frequency and try again.
Once you get a response, there is no need for further activations of the Emergency Call button.

Licensing of Radio Equipment

You will need an Outpost Non-assigned Radio Licence to transmit using an HF Radio.
