Sample Exam 1

A good radio amateur always uses the International Phonetic alphabet. But some use their own set of words. For example "Bravo" replaced by "Barcelona". Sierra replaced by "Sugar”. Ideally this should be avoided.

These abbreviations are used only in CW transmission. Starting signal - KA (dah di dah di dah); invitation to transmit - K (dah di dah); break in - BK (dah di di di dah di dah); signal used to a transmission in progress - BK (dah di di di dah di dah)

H3E= SSB full carrier, analog, telephony; A3E = double side band, analog, telephony; A1A = double side band, digital info , telegraphy; J3E =SSB suppress carrier, analog, telephony.

QSD = keing defective (mutilated); QSV = series of “ V “s ; QSB = fading; QSY = change frequency ; Also note that a Q qode is used both as a statement and a question: QRM?= Are you having interference?, QRM = I am having interference.

end of work - VA or SK (di di di dah di dah); end of transmission – AR (di dah di dah dit) ; invitation to a particular station to transmit – KN (dah di dah dah dit); waiting period- AS( di dah di di dih)

If you replace the antenna by a dummy load, RF power output from the TX is totally absorbed by the dummy load and no power is radiated out side. You can do any test or adjustment of the TX under this condition. It’s prevent annoying other uses on the band.

all after - AA; answer again or repeat message -RPT; all received – R; These abbreviations use only with Morse.

increase transmitter power = QRO; decrease transmitter power = QRP; send faster = QRQ; ready = QRL

CL - closing station; CP - General call to 2 or more specified stations (not use in amateur radio); C - yes; CQ - general call to any station. These are only for CW transmissions.

Your signals are mutilated (keying defective) = QSD; I am ready. = QRV; Send faster = QRQ; I can send on my working frequency = QSU; (QSU is not use in amateur radio)

QSS = working frequency; QRS = send slowly; QSL = Acknowledge; QSU = Send on this frequency; ( QSU and QSS not use in amateur radio)

Logical procedure. You call a station (him/her)and say who is calling that station(You)

QRV = ready; QSV = series of “ V “s ; QRP = low power ; QRQ = send faster.; Also note that a Q qode is used both as a statement and a question: QRM?= Are you having interference?, QRM = I am having interference.

:- Exact frequency = QRG; Does my frequency vary? = QRH ?; Readability = QRK ; What is the tone on my transmission? = QRI? , reply will be QRI 1 or 2 or 3 .....9

/ M = mobil operation; / P = portable operation ; / MM = maritime mobile

If the callsign 4S7XX then use 4S7XX/A for alternate location, /P for portable operation, /M for mobile operation, /MM for maritime mobile operation.

In the licence document not mentioned anything about Phonetic alphebet or Q-code.

QSY = change frequency; QSV = series of “ V “s ; QSP = message relay to ...; QST = no Q-code like this. There is a HAM radio magazeen named “QST”. Also note that a Q qode is used both as a statement and a question: QRM?= Are you having interference?, QRM = I am having interference.

A log book entry should show the date, time(UTC), frequency, type of emission used And the call sign of the station conbtacted the quality of the signal received by the receiving station and how the seignal was received by the other station usually in RST code. For voice transmission (RS) CW (RST) R=Readability S=Strength T= Tone

Plain language is better for Voice communication and better to use Q code for CW. But there is no hard and fast rule. The use of secret code is prohibited in Amateur Radio communication.

Tests to a dummy load are not radiated out of your shack. All others including CQ calls even if no one answers are transmissions made, thus requiring entry in a log book.

QRL = busy; QSL = Acknowledge; QRT = stop sending; QRX = standby

Without a valid licence issued by the Director General of Telecommunication, no one is allowed to use such equipment. At a JOTA or an exhibition with prior permission from the DGT operation is allowed under the strict supervission of a licensed radio amateur to use Amateur Radio transmitting equipment.

A2A = double side band ,modulating sub carrier by digital info, telegraphy; A1A = double side band, without modulating by digital info, telegraphy; J3E = SSB supressed carrier, analog info, telephony; H3E = SSB full carrier, analog info, telephony.

Send more slowly = QRS; Change transmission to another frequency = QSY; Stop sending = QRT; I will call you again = QRX

A3E = DSB, analog info, telephoney; F3E = FM, analog info, telephoney; H3E = SSB full carrier, analog info, telephoney; J3E = SSB supress carrier, analog info, telephoney.

F3E = FM, analog info, telephoney; A3E = DSB, analog info, telephoney; H3E = SSB full carrier, analog info, telephoney; J3E = SSB supress carrier, analog info, telephoney.

The use of secret codes is prohibited in Amateur Radio communications. Plain language with international phonetic alphabet and normal spoken language is better in Voice communication. Q code is better for CW. But there is no hard and fast rule.

Secret codes are not permitted. A monitoring station set up by the licensing authority should be able to deciphure any transmission. Some countries forbid the use of languages other than the official languages of that country.

Always use only UTC. But in the remarks column you can note down other time for future reference. For international communications we always use a standard time familiar to all stations which is Universal Coordinated Time (UTC) which replaced GMT.

Applicant must be over 14 years of age. According to the new regulations Morse test is not required for Novice and General Class. Morse test conduct only for advanced class (5 WPM).

In RST code tone can be indicate by a number 1 to 9. ; 1-extremly rough, 2-very rough a.c., no trace of musically, 3-rough low pitched a.c., slightly musical, 4-rough a.c., moderatly musical, 5-musically modulated, 6-modulated slight trace of whistle, 7-near d.c. note smooth ripple, 8-good d.c. note, 9-purest d.c. note.

A test transmission is made to test a transmitter on the air while radiating a signal. Therefore the recommended way is to send a series of “V” in Morse Code and since every tramsission has to be identified the station call sign has to be sent

The laid down rule is that it should be a bound book and pages numbered. Bound book so that lose sheets don’t fly off and numbered because a chronological record must be kept which is common sense. You can use computer print out log sheets as long as they are bound together and numbered.

A directional call is when a specific station is called, therefore, only that station should respond not others.

Some countries, phone patched traffic allowe, but not in Sri Lanka.

:- Always Listen on the frequency before comencing a transmission then for voice, it is good practice to ask “Is this frequency occpied?” and your callsign and listen; for CW send “ ? “ or “ QRL?” followed by your callsign. Send this msg once or twice and listen, then start a CQ call.; A 1750Hz tone is used to activate VHF or UHF repeaters; If you want to do some adjustment of TRX, first listen and send a series of Vs in Morse following by your callsign. For voice , send your callsign. There are times when a two way contact is in progress on a frequency but only one station could be heard in your location. The above requirement is to avoid any interference to ongoing traffic.

QRX = standby or I will call you at time.....; QRV = ready; QRU = have you an thing to tell or I have nothing to tell : QRZ = who is calling
