Question 1 |
Which of the following types of message cannot be transmitted over amateur radio ?
A | message of a religious nature |
B | the words of a third party publicly spoken |
C | those of personal affairs |
D | messages relating to technical investigation |
Question 1 Explanation:
Religious , Political and business type messages are prohibited to pass through Amateur Radio. The Amateur Radio License is not a substitute for a telephone. Religious and political discussions are best made in private, as we say at “Eyeball level”. Your views could offend and also disturb others and even be a public nusance and cause disorder. An amatuer license is granted for experimental purposes and is not a license to run a Broadcasting Station.
Question 2 |

Question 2 Explanation:
QSL = aclnowledge ; QSB = fading ; QSD = keying defecting ; QSP = relay a msg. ; If a question send “?” after the Q-code.
Question 3 |
The correct group using international phonetic alphabet is
A | KILO, LIMA, MARY, ROBERT |
B | KING, LIONEL, MARY, ROBERT |
C | KING, LIONEL, MIKE, ROMEO |
D | KILO, LIMA, MIKE, ROMEO |
Question 3 Explanation:
Some operators use another or their own phonetic alphabet, but it is always better to use the inernational standard phonetic alphabet. A standard is used so that everyone uses the same alphabet. Under difficult conditions a standard alphabet will be better understood and even by people who do not have the same level of fluency in a language, if all use a standard phonetic alphabet. It might also be a good idea on your way to becoming a good operator to brush up your pronunciation of the Phonetic Alphabet and even numerals Eg: some operators is some countries pronounce G=Golf as Go-lof or Golphuuu.
Question 4 |
When calling a station it is good practice to
A | use the callsign of the other station only |
B | use your callsign only |

Question 4 Explanation:
While you are pressing the PTT, you can’t hear the other person. There must be an indication when you press the PTT or release. When you start transmitting, First say other person’s callsign and then your callsign, after finishing your turn again you must say other person’s callsign, then your call sign and relese the PTT. Some other systems other than amateur radio use different types Example: “over”, “goahead”

Question 36 Explanation:
The maximum duration permitted by regulatons for a single transmission is 10 minutes. Callsign should be transmitted once in every 5 minutes. Avoid long transmissions because your signal might fade out and you will be talking to thin air!!. In a round table of 3 or more people especially on a DX contact such long overs will rob the others of their turn because by then propagation would have changed or one person or more in the group might be in a hurry to leave.

A3E = DSB ,analog info, telephony (voice ); J3E = SSB supperss carrier, analog info, telephony ( voice); H3E = SSB with full carrier,analog info, telephony ( voice) ; F3E = FM,analog info, telephony ( voice transmission)
Question 39 |
Using voice modulation, J3E corresponds to
A | SSB with suppressed carrier |
B | SSB with full carrier |
C | FM |
D | DSB |
Question 39 Explanation:
J3E = SSB suppressed carrier, voice transmission ; for SSB full carrier, first charactor should be H ; for DSB, first charactor should be A ; for FM first charactor should be F.

‘Are you troubled by static ?’ is given by Q-code
A | QRQ |
B | QRP |
C | QRN |
D | QRO |
