The Unlicensed Visitor Wanting to Transmit
Marcus holds a standard amateur licence. His friend Dev has no amateur licence at all but has studied electronics and wants to try a contact. They are at Marcus's shack, which has a 100 W HF transceiver and a 50 W VHF radio. Dev asks to press the push-to-talk and say hello on 7.150 MHz while Marcus supervises. Marcus also has a cousin, Lena, who holds a licence issued in another country and is visiting for three weeks; Lena wants to operate Marcus's station using her own call sign. Marcus is unsure what he may allow, whether supervision makes any difference, and whether Lena needs anything before transmitting.
1. May Marcus let Dev, who holds no licence, transmit on the HF transceiver under Marcus's supervision?
Read the worked answer
No. Amateur licences are personal: the privilege to transmit belongs to the licensed person, and unlicensed operation is not made lawful by having a licensee present. Supervision does not create a licence for Dev, and Marcus cannot 'lend' his authority so that Dev transmits. If Dev transmits, both Dev (unlicensed operation) and potentially Marcus (aiding unlicensed operation) are exposed to enforcement action. What Marcus can lawfully do is demonstrate, let Dev listen, and explain the equipment while Marcus operates the controls and does the transmitting. Dev should obtain his own licence, starting at foundation level, before pressing PTT.
2. What must be established before Lena, a visiting overseas licensee, may transmit using her own call sign from Marcus's station?
Read the worked answer
Lena's foreign licence does not automatically authorise operation in Australia. Visiting amateurs generally need a recognised authorisation, such as a reciprocal or visiting-amateur permit or a locally issued licence, and they may be required to use a call sign with an Australian prefix or a specified identifier. The exact requirements depend on Australia's arrangements with the country that issued her licence and on the class of her overseas licence. Before any transmission, Marcus and Lena should check the current requirements with the regulator, confirm which bands and power her authorisation covers, and confirm the call sign she must use. She should not transmit on the assumption that her home licence travels with her.
3. If Lena is properly authorised, what responsibility does Marcus carry as the station licensee while she operates his equipment?
Read the worked answer
Marcus remains responsible for his station and its compliance. He should confirm that Lena's permitted bands and power match what his equipment can produce, that she uses the correct call sign and identification, and that she understands Australian operating requirements and band plans. He should be present or reachable, ensure the transmitter is not left for uncontrolled use, and stop operation if a problem arises. He should also check that using his station by a visitor is permitted under his licence conditions. The key reasoning is that authorisation for the visitor does not transfer responsibility for the station away from its licensee.
