CW Lives When selecting a CW transmitting frequency, 150 to 500 Hz is the minimum frequency separation you should allow in order to minimize interference to stations on adjacent frequencies. (G2B04) The term “zero beat” in CW operation means matching your transmit frequency to the frequency of a received signal. (G2C06) The best speed to use answering a CQ in Morse Code is the speed at which the CQ was sent. (G2C05) When sending CW, a “C” added to the RST report means a chirpy or unstable signal. (G2C07) RST stands for R eadability … Signal S trength … T one
CW Lives READABILITY (R) for Voice + CW 1 – Unreadable 2 – Barely readable, occasional words distinguishable 3 – Readable with considerable difficulty 4 – Readable with practically no difficulty 5 – Perfectly readable
CW Lives SIGNAL STRENGTH (S) for Voice + CW 1 – Faint, barely perceptible signals 2 – Very weak signals 3 – Weak signals 4 – Fair signals 5 – Fairly good signals 6 – Good signals 7 – Moderately strong signals 8 – Strong signals 9 – Extremely strong signals
CW Lives Tone (T) Use on CW only 1 – Very rough, broad signals, 60 cycle AC may be present 2 – Very rough AC tone, harsh, broad 3 – Rough AC tone, rectified but not filtered 4 – Rough note, some trace of filtering 5 – Filtered rectified AC but strongly ripple-modulated 6 – Filtered tone, definite trace of ripple modulation 7 – Near pure tone, trace of ripple modulation 8 – Near perfect tone, slight trace of modulation 9 – Perfect tone, no trace of ripple or modulation of any kind
CW Lives Q signals are three letter combinations that begin with the letter ‘Q’ If a CW station sends "QRS", send slower. (G2C02) The Q signal "QRQ" means “send faster.” (G2C10) The Q signal “QRV” means, “I am ready to receive messages.” (G2C11) The Q signal "QSL" means, “I acknowledge receipt.” (G2C09) Q signals always begin with the letter ‘Q’ and have only three letters.
99 CW Lives Something is causing interference I am troubled by static/noise. I am running low power. Send faster ( ____ WPM) Send more slowly ( ___ WPM) I am going off the air. I am ready Who is calling me? Your signal is fading. I received the message. I will communicate with ________ directly. I am changing frequency to _____. My location is _______. QRM QRN QRP QRZ QSB QSL QSO QSY QTH QRT QRQ QRS QRV These four are the only ones on the exam.
CW Lives When a CW operator sends "KN" at the end of a transmission, it means the operator is listening only for a specific station or stations. (G2C03) This is called a ‘prosign’ and is used on CW only. AR is the prosign that is sent to indicate the end of a formal message when using CW. (G2C08) When a CW operator sends "CL" at the end of a transmission, it means “closing station,” or that the operator is going off the air. (G2C04) When using full break-in telegraphy (QSK), transmitting stations can receive between code characters and elements. (G2C01) If another station wishes to interrupt, you will hear its signal between your dots and dashes
CW Lives Observation of propagation and reception is a purpose of a beacon station as identified in the FCC Rules. (G1B03) Beacon stations are found at MHz, MHz, MHz, MHz, MHz, and on 2 meters below MHz.
100 watts PEP output is the power limit for beacon stations. (G1B10) One of the conditions with which beacon stations must comply is that there must be no more than one beacon signal in the same band from a single location. (G1B02) An advantage of selecting the opposite or "reverse" sideband when receiving CW signals on a typical HF transceiver is that it may be possible to reduce or eliminate interference from other signals. (G4A02) It is good to match receiver bandwidth to the bandwidth of the operating mode because it results in the best signal to noise ratio. (G8B09) CW Lives
The purpose of an electronic keyer, for example, is automatic generation of strings of dots and dashes for CW operation. (G4A10) CW Lives
