The 5 W Handheld on a 50 W Foundation Licence
Priya holds an Australian foundation licence, which authorises a maximum transmitter power of 10 W. She owns a handheld transceiver whose low setting is 5 W and high setting is 8 W. On a hilltop she makes contact with a station 60 km away on 146.500 MHz. The other operator suggests she switch to high power to improve the path, and also suggests she try the 70 cm repeater input frequency, which is outside the foundation licence's permitted frequency bands. Priya is unsure whether the 8 W setting is allowed, whether she may use the 70 cm input, and whether her hilltop location changes anything. Her licence document lists permitted bands and a power limit, and she has no other authorisation.
1. Is Priya permitted to use the 8 W high-power setting on her handheld? Explain the reasoning against the licence conditions.
Read the worked answer
Yes. The foundation licence power limit is 10 W transmitter output power, and 8 W is below that ceiling. The relevant test is not whether a setting feels high but whether the transmitter's peak output power stays within the licence maximum. Because 8 W is less than 10 W, the high setting is lawful on the bands her licence permits. She should confirm the figure is transmitter output power rather than something like DC input or ERP, since licence limits are usually expressed as output power at the transmitter. She should also check that the handheld is not a modified or non-compliant device. The suggestion to switch to high power is therefore fine, provided she remains on an authorised frequency.
2. May Priya transmit on the 70 cm repeater input frequency suggested by the other operator? What principle governs this?
Read the worked answer
No. A foundation licence authorises operation only on the frequency bands listed in the licence conditions. A repeater input frequency that falls outside those listed bands is not authorised, even if the equipment can tune to it and even if another licensed operator suggests it. The other operator's suggestion does not extend her privileges; only her own licence class and any special authorisation do. She should decline and, if she wants 70 cm access, look at upgrading her licence class or checking whether the band is in fact listed for her class. The governing principle is that operating privileges are defined by the licence, not by equipment capability or by what other amateurs do.
3. Does operating from a hilltop change Priya's obligations or limits?
Read the worked answer
No. The licence conditions apply wherever she operates within Australia; a hilltop does not create extra privileges or relax power or band limits. The location may improve her range, which increases the chance of interfering with other users, so she should be more careful about frequency selection and keep transmissions short and identified. She must still use her assigned call sign and identify at the required intervals. If the hilltop is in a different state or territory, the same licence conditions still apply, though she should be aware of any local band plans or repeater coordination arrangements. Good practice on a high site includes listening before transmitting and avoiding frequencies used by weak-signal or beacon services.
