11. The distance that line of sight VHF and UHF signals can travel is dependent on the:- a) time of day, sun spot cycle and weather b) height of antenna, ionosphere, and time of day c) sun spot cycle, weather, and ionosphere d) height of antenna, clear path, and transmitter power

12. A radio amateur's transmission can be heard in a nearby neighbour's television receiver. These problems are best solved by:- a) reducing the transmitter power until the problems disappears b) a technical solution c) not transmitting during the neighbour's viewing hours d) ignoring the problem as you have a licence

13. During a thunderstorm the amateur station should:- a) keep operating at reduced power b) not be operated c) stand by for distress calls d) increase power to overcome static

15. An amateur transceiver that is being over modulated may result in:- a) an increase in the feedline loss b) improved signal reports c) a reduction of power output d) interference to other services

16. Cables and leads left lying around the station are potential:- a) sources of mains hum b) trip hazards c) generators of interference d) short circuits
