International communication : [Information]
IARU (International Amateur Radio Union ) is an international confederation of national organisations that allows a forum for common matters of concern to amateur radio operators worldwide, and collectively represents matters to the International Telecommunication Union (ITU).
Amateur radio is officially represented and coordinated by the IARU which is organized in three regions and has as its members the national amateur radio societies which exist in most countries. (Philippines is in Region 3).
ITU (International Telecommunication Union) is the leading United Nations agency for information and communication technology issues.
International Q Code is an abbreviated way to exchange information. The Q Code consists of three-letter groups with each group having a specific meaning. Each group begins with the letter Q

The RTTY frequency shift between the two tones is usually170 Hz
AMTOR (amateur teleprinting over radio) is a digital communications method used by radio amateurs, in which the frequency of errors is reduced by handshaking or character repetition....AMTOR utilizes FSK (frequency-shift keying) with a frequency shift of 170 Hz, and a symbol rate of 100 Baud.
PSK31(Phase Shift Keying 31 baud (or 31 bits per second/bps) is a digital mode used on the amateur radio bands. It derives its name from the fact that it uses phase shift keying, PSK rather than frequency shift keying,its data rate is 31.25 bauds (about 50 word-per-minute), and its narrow bandwidth (approximately 60 Hz at -26 dB)
Baud Rate : The baud rate is the rate at which information is transferred in a communication channel....It is usually expressed in units of bits-per-second (bps).

Radio telegraphy, Wireless Telegraphy : [Information]
Radio telegraphy is a communications system in which information is transmitted and received over long distances over a wire or by using radio waves usually in the form of Morse code (CW)
SOS is the International Morse code distress (emergency) signal
Wireless telegraphy means transmission of telegraph signals by radio waves; a more specific term for this is radiotelegraphy. In a manual system, the sending operator taps on a switch called a telegraph key which turns the transmitter on and off, producing the pulses of radio waves.
CW stands for "continuous wave" or "carrier wave" transmissions
Amateur Radio Telegraphy Abbreviations include: [Information]
DE = From
KN = Invite a specific station to transmit
SK = End of Contact
K = Invite any station to transmit
Amateur Radio Operating Courtesy includes : [Information]
Do not tune your transmitter (transceiver) on frequencies being used.
Always listen in a few seconds, a minute if necessary, before calling for a “CQ” on frequency
If using repeater systems, always see to it that QSO are short.
Never use abusive terms, stay polite, courteous and gentle, under all circumstances.
Q codes include:
QRN = Static interference
QRM = Man Made Interference
QRO = Increase power
QRP = Decrease power
Sensitivity :
The sensitivity of an electronic device, such as a communications system receiver, or detection device, such as a PIN diode, is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria
Selectivity :
Selectivity is a measure of the performance of a radio receiver to respond only to the radio signal it is tuned to (such as a radio station) and reject other signals nearby in frequency, such as another broadcast on an adjacent channel.
Radiotelephony : [Information]
Radiotelephony means transmission of sound (audio) by radio, in contrast to radiotelegraphy (transmission of telegraph signals) or video transmission.
A radiotelephone (or radiophone) is a communications system for transmission of speech over radio.

NTC : Memorandum Order : MO - 04 - 03 - 2011.....[Information]
Subject : Authorizing the Use of Radio Frequencies at Times of Disasters and National Emergencies.
To ensure uninterrupted communications during typhoons, disasters and other national emergencies , the following frequencies are hereby authorized for the use of participating entities and/or organizations in providing public assistance:
For Amateur Radio Groups : 7095.0 Khz.....Calling frequency 144.740 Mhz.....Calling frequency 147.500 Mhz.....Working frequency 147.575 Mhz.....Alternative frequency
Note : Emergency Channel be used only for emergency communication and general calling for radio telephony, the exam may use these (old) frequencies. 7.045 MHz and 145.000 MHz (+ -25 KHz)
Transmitter tune up [Information]
Tune the transmitter into a dummy load. Reduce the transmit power and select a frequency not in use. Connect the antenna and adjust the ATU for minimum SWR Adjust power output to the required level and ask if the operating frequency is occupied.
Amateur Radio Telegraph Abbreviations include: [Information]
R = Means the last transmission has been received as transmitted. BT = Break in text.
AS = Wait (please stand by). AGN = Again (repeat)
AR = End of Message / End of transmission. BK = Break : Invite receiving station to transmit.
CL = Closing : I am closing my station. IMI = (Question Mark) : Say again or I say again
Repeaters : [Information]
Output Frequency: The frequency that the repeater transmits on, and you listen on...
The Offset: The difference between the Output and the Input frequencies (either a positive or a negative frequency). For 2m repeaters, the offset is normally 600kHz below the Output frequency. For example: A repeater, transmits on 145.725MHz (the Output), and listens on 145.125MHz (the Input). The Offset is minus 600kHz.....
The CTCSS Tone: This is required to allow your signal to be forwarded by the repeater
What should you do before you transmit on any frequency? [Information]
Listen to make sure others are not using the frequency.
Example : Ask "Is this frequency is occupied?" or "Is this frequency in use?" before calling CQ.
Using morse code it would be QRL IMI = Is this frequency busy?" or "Is this frequency in use?"
The "squelch" or "muting" circuitry on a VHF receiver:
compresses incoming voice signals to make them more intelligible
to mute receiver audio output noise when no signal is being received
reduces audio burst noise due to lightning emissions
The RIT control on a transceiver changes the receive frequency in fine increments up or down whilst the transmit frequency stays the same on the main frequency display.Some manufacturers call this a clarifier (CLAR) control.
By slightly adjusting the receiver frequency with RIT, you can sometimes get better reception of a station that is transmitting slightly off frequency. Your transmitting frequency does not change when adjusting RIT.
XIT (Transmit Incremental Tuning) is the ability to shift the transmit frequency of a transceiver away from the receive frequency by a small amount.
Split frequency operating means transmitting on one frequency and receiving on a different frequency.
