2 Notice to candidates You must not talk to or distract any other candidate in the exam room. You are not allowed any assistance with the exam questions and the invigilator is not permitted to discuss exam questions. If you need other assistance, please raise your hand and talk quietly to an invigilator when approached. You may not leave the exam room without permission and may not re-enter the room unless you have been escorted by an invigilator at all times. You must use a blue or black pen for your answers and any calculations may be done on the reverse of the question paper.

3 1 Which, of the items listed below, is NOT a type of Amateur licence? Intermediate Foundation Beginner Full 6 Which part of an amateur band is not permitted within 100km of Charing Cross, London? MHz MHz MHz MHz 2 When transmitting, you must give your call sign when establishing contact and on every over every 5 minutes every 15 minutes at the end of the contact. 7 The correct formula relating the voltage, V, the current, I, and the resistance R is R = V - I R = V I R = I / V R = V / I 3 You are talking to M3ABC by amateur radio and friends enter his room. You may also talk to them if they are a family members if M3ABC gives permission if they are also amateurs but only on the calling channel. 8 To allow the bulb in the diagram to light correctly, a wire should be connected between points 4 If an amateur changes address, he/she should notify the Police the RSGB (Radio Society of Great Britain) Ofcom the local radio club. 5 On which one of the frequencies below may a Foundation licensee transmit? 7 5MHz 15MHz 72MHz 145MHz 1 and 2 1 and 3 2 and 3 2 and 4 9 The UK mains supply is 230V D.C. 230V 50Hz 230V 60Hz 230V 100Hz 3

4 10 The frequency 121 5MHz is used for Aeronautical radio Amateur radio Land based radio Satellite radio. 13 In the block diagram of a radio receiver shown, what is the function of the box marked 2? 11 What is the function of the box marked 2 on the transmitter block diagram? Tuning and RF amplification. Detection. Audio amplifier. Loudspeaker. Frequency generation oscillator RF amplifier Modulator Audio amplifier 14 The output from the transmitter should be connected to the antenna by waterproof mains cable screened audio cable fuse wire coaxial cable. 15 Which drawing shows a dipole antenna? 12 Excessive amplitude modulation may cause the transmit frequency to drift interference to adjacent channels the received voice to become higher in pitch A B the standing wave ratio to increase above its limits. C D Drawing A Drawing B Drawing C Drawing D. 4

6 24 What is the most serious risk when working inside equipments using high voltages? Such equipments are more likely to develop a fault. Spare parts are harder to obtain. High voltage equipments are more complicated and harder to repair. There is a risk of receiving a fatal electric shock. 25 You find an amateur friend lying on the floor, silent and not moving, beside his transmitter which has fallen off the desk. You should go for help turn him face up switch off the power pull any microphone and other cables away from him. Answers C C C C D C D A B A C B B D C A A A D C D B B D C 6
