Listen first

Always listen before transmitting to ensure that the frequency is not already in use.

Calling another station

Use the callsign of the station being called first repeated a maximum of 3 times, then the words, THIS IS, followed by your callsign repeated a maximum of 3 times, ending with OVER, e.g.:

VK6ZZ VK6ZZ VK6ZZ THIS IS VK2KO VK2KO VK2KO OVER

This call may be modified as conditions permit – i.e. if you are using an FM repeater, it is not necessary to repeat the callsigns 3 times, and THIS IS and OVER can be dispensed with – e.g.

VK6ZZ (brief pause) VK2KO

Reply

Again, use the other station’s callsign, followed by THIS IS (if required) and then your callsign followed by GO AHEAD and OVER, e.g.:

VK2KO, THIS IS VK6ZZ, GO AHEAD OVER

General “CQ” call

A general call to any other amateur station (i.e. you are looking for a contact with any other station) may be made by substituting the signal ‘CQ’ in place of the called station’s callsign, e.g.:

CQ CQ CQ THIS IS VK9YZ VK9YZ VK9YZ OVER

Using repeaters

As discussed previously, when using a repeater, you can dispense with THIS IS and OVER.

CQ calls are not normally made on repeaters – you simply announce that you are listening e.g.:

VK7AB listening.

Breaking into an existing QSO (contact)

If you wish to break into an existing contact between two stations, wait for a pause and announce your callsign only.  Do not talk over the top of the stations.
