Operating through a repeater
You will be required to demonstrate the correct use of voice repeaters including the use of Continuous Tone Coded Squelch System (CTCSS) and Dual Tone Multiple Frequency (DTMF) access control systems.
As with any frequency, always listen first to ensure the repeater is not already in use.
When operating through a repeater leave adequate breaks between transmissions. This will allow other users to access the repeater if required. If you are likely to have an extended contact and the other station is within range, you should move to a simplex frequency and leave the repeater available for other users.
You normally do not call CQ on a repeater – just announce that you are listening – i.e. “VK2ABC listening”
