Operating and Procedures
tuneups and testing, use of dummy load, courteous operation
What should you do before you transmit on any frequency?
-
Check your antenna for resonance at the selected frequency
-
Correct AnswerListen to make sure others are not using the frequency
-
Make sure the SWR on your antenna feed line is high enough
-
Listen to make sure that someone will be able to hear you
Tags: none
If you contact another station and your signal is extremely strong and perfectly readable, what adjustment might you make to your transmitter?
-
Turn on your speech processor
-
Reduce your SWR
-
Continue with your contact, making no changes
-
Correct AnswerTurn down your power output to the minimum necessary

What is one way to shorten transmitter tune-up time on the air to cut down on interference?
-
Use a random wire antenna
-
Tune up on 40 metres first, then switch to the desired band
-
Use twin lead instead of coaxial cable feed lines
-
Correct AnswerTune the transmitter into a dummy load
Tags: none
How can on-the-air interference be minimized during a lengthy transmitter testing or loading-up procedure?
-
Choose an unoccupied frequency
-
Use a non-resonant antenna
-
Use a resonant antenna that requires no loading-up procedure
-
Correct AnswerUse a dummy load
Tags: none
Why would you use a dummy antenna?
-
To give comparative signal reports
-
Correct AnswerTo allow antenna tuning without causing interference
-
It is faster to tune
-
To reduce output power

If you are the net control station of a daily HF net, what should you do if the frequency on which you normally meet is in use just before the net begins?
-
Correct AnswerConduct the net on a frequency 3 to 5 kHz away from the regular net frequency
-
Reduce your output power and start the net as usual
-
Increase your power output so that net participants will be able to hear you over the existing activity
-
Cancel the net for that day
Tags: none
If a net is about to begin on a frequency which you and another station are using, what should you do?
-
Correct AnswerAs a courtesy to the net, move to a different frequency
-
Increase your power output to ensure that all net participants can hear you
-
Transmit as long as possible on the frequency so that no other stations may use it
-
Turn off your radio
Tags: none
If propagation changes during your contact and you notice other activity on the same increasing interference from frequency, what should you do?
-
Tell the interfering stations to change frequency, since you were there first
-
Report the interference to your local Amateur Auxiliary Coordinator
-
Increase the output power of your transmitter to overcome the interference
-
Correct AnswerMove your contact to another frequency
Tags: none
When selecting a single- sideband phone transmitting frequency, what minimum frequency separation from a contact in progress should you allow (between suppressed carriers) to minimize interference?
-
Correct AnswerApproximately 3 kHz
-
150 to 500 Hz
-
Approximately 6 kHz
-
Approximately 10 kHz
Tags: none
What is a band plan?
-
A plan of operating schedules within an amateur band published by Industry Canada
-
Correct AnswerA guideline for using different operating modes within an amateur band
-
A plan devised by a club to best use a frequency band during a contest
-
A guideline for deviating from amateur frequency band allocations
Tags: none
Before transmitting, the first thing you should do is:
-
ask if the frequency is occupied
-
make an announcement on the frequency indicating that you intend to make a call
-
decrease your receiver's volume
-
Correct Answerlisten carefully so as not to interrupt communications already in progress
