SYLLABUS FOR AMATEUR RADIO STATION OPERATOR CERTIFICATE (ASOC) LICENCE EXAMINATION

PART - 1: WRITTEN TEST.

SECTION - A : RADIO THEORY AND PRACTICE.

ELEMENTARY ELECTRICITY AND MAGNETISM :
Elementary theory of electricity: Conductors and insulators, units. Ohm's Law, resistance, capacitance, inductance in series and parallel, conductance, power and energy, permanent magnets and electromagnets and their use in radio work, self and mutual inductance: types of inductors used in receiving and transmitting circuit.

ELEMENTARY THEORY OF ALTERNATING CURRENTS:
Sinusoidal alternating currents-peak, instantaneous, RMS, average values, phase, resistance, Impedance. Circuits containing resistance, inductance, capacitance-power factor resonance in series and parallel circuits, coupled circuits, transformers for audio and radio frequencies.

THERMIONIC VALVES:
Construction of valves thermionic emission, characteristic curves, diodes, triodes and multielectrode valves: use of valves as rectifier, oscillator, amplifier, detectors and frequency changers, Power packs, stabilisation and smoothing elementary theory and construction of semiconductor devices, diodes and transistors.

RADIO RECEIVERS:
Principles and operation of Tuned radio Frequency and superheterodyne receivers, CW reception: Receiver characteristics. Sensitivity, selectivity, fidelity: adjacent channel and image interference: AVC and squelch circuit Signal to noise ratio, TRANSMITTER:principles and operation of low power transmitter, crystal oscillator ,stability of oscillators. RADIO PROPAGATION: Wave Length, frequency, nature and propagation of radio waves: ground and sky waves, skip distance, fading. AERIALS: Common types of transmitting and receiving aerials.FREQUENCY MEASUREMENT: Measurement of frequency and use of simple frequency meters.

( NOTE : For Advanced Grade Separate paper will be given which will include Satellite communication along with above said syllabus and have to answer all the questions )

PART - II MORSE CODE

FOR GRADE-II

(a) SECTION-1: Morse receiving (Speed 5 Words Per Minute)
The test piece will be consist of plain language passage of 125 letters. Five letters counting as one word. Candidates are required to receive for 5 consecutive minutes at a speed of 5 words per minute international morse code signals from an audio oscillator keyed either manually or automatically. A short practice piece may be sent at the prescribed speed before the start of the actual test. The test may be written in ink or pencil but must be legible. Bad handwriting and over-wirting will render a candidate liable to disqualification. More than 5 errors will disqualify a candidate in a stretch of 60 characters.

(b) SECTION-2 : Morse Sending (Speed 5 Words Per Minute)
The test piece will consists of a plain language passage of 125 letters, 5 letters counting as one word.
Candidates are required to send on an ordinary key for 6 consecutive minutes at the minimum speed of 5 words per minute. A short practice piece may be allowed before the actual test. Candidate will not be allowed more than one attempt in the test. Efforts should be made to correct all errors. However more than 5 errors will disqualify a candidate. The accuracy of signalling, correct formation of characters and the correctness of spacing shall be taken into account.
NOTE: A candidate is required to pass both in Part 1 and Part II. In the case of candidates qualifying in part I only the licence shall be restricted to radio telephone operations only

FOR GRADE I AND ADVANCED GRADE

Morse sending and receiving speed is 12 WPM. The test piece will consist of plain language passage of 300 characters which may comprise of letters, figures, and punctuation (Full stop, comma, semi-colon, break sign, hyphen and question mark). The average words shall contain 5 characters and each figure and punctuation will be counted as 2 characters. Other conditions are same as in grade II. A candidate is require to pass in Part I(Written) and Part II (Morse) simultaneously.
