Q

What is a practical way to avoid harmful interference on an apparently clear frequency before calling CQ on CW or phone?

26
What does it mean when a CW operator sends “KN” at the end of a transmission?
Listening only for a specific station or stations
27
What does the Q signal “QRL?” mean?
“Are you busy?” or “Is this frequency in use?”
28
What is the best speed to use when answering a CQ in Morse code?
The fastest speed at which you are comfortable copying, but no faster than the CQ
29
What does the term “zero beat” mean in CW operation?
Matching the transmit frequency to the frequency of a received signal
30
When sending CW, what does a “C” mean when added to the RST report?
Chirpy or unstable signal

What is the Volunteer Monitoring Program?
Amateur volunteers who are formally enlisted to monitor the airwaves for rules violations
36
Which of the following are objectives of the Volunteer Monitoring Program?
To encourage amateur radio operators to self-regulate and comply with the rules
37
What skills learned during hidden transmitter hunts are of help to the Volunteer Monitoring Program?
Direction finding used to locate stations violating FCC rules
38
Which of the following describes an azimuthal projection map?
A map that shows true bearings and distances from a particular location
39
Which of the following is a good way to indicate on a clear frequency in the HF phone bands that you are looking for a contact with any station?
Repeat “CQ” a few times, followed by “this is,” then your call sign a few times, then pause to listen, repeat as necessary
40
How is a directional antenna pointed when making a “long-path” contact with another station?
180 degrees from the station’s short-path heading
41
Which of the following are examples of the NATO Phonetic Alphabet?
Alpha, Bravo, Charlie, Delta
42
What is a reason why many amateurs keep a station log?
To help with a reply if the FCC requests information
43
Which of the following is required when participating in a contest on HF frequencies?
Identify your station per normal FCC regulations
44
What is QRP operation?
Low-power transmit operation
45
Which of the following is typical of the lower HF frequencies during the summer?
High levels of atmospheric noise or “static”
46
Which mode is normally used when sending RTTY signals via AFSK with an SSB transmitter?
LSB
47
How can a PACTOR modem or controller be used to determine if the channel is in use by other PACTOR stations?
Put the modem or controller in a mode which allows monitoring communications without a connection
48
What symptoms may result from other signals interfering with a PACTOR or WINMOR transmission?
