B-002-04: Tuneups and testing, use of dummy load, courteous operation
B-002-04-01:
What should you do before you transmit on any frequency?
Listen to make sure others are not using the frequency
Check your antenna for resonance at the selected 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
B-002-04-02:
If you contact another station and your signal is extremely strong and perfectly readable, what adjustment might you make to your transmitter?
Turn down your power output to the minimum necessary
Turn on your speech processor
Reduce your SWR
Continue with your contact, making no changes
B-002-04-03:
What is one way to shorten transmitter tune-up time on the air to cut down on interference?
Tune the transmitter into a dummy load
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
B-002-04-04:
How can on-the-air interference be minimized during a lengthy transmitter testing or loading-up procedure?
Use a dummy load
Choose an unoccupied frequency
Use a non-resonant antenna
Use a resonant antenna that requires no loading-up procedure
B-002-04-05:
Why would you use a dummy antenna?
To allow antenna tuning without causing interference
To give comparative signal reports
It is faster to tune
To reduce output power
B-002-04-06:
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?
Conduct 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
B-002-04-07:
If a net is about to begin on a frequency which you and another station are using, what should you do?
As 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
B-002-04-08:
If propagation changes during your contact and you notice increasing interference from other activity on the same frequency, what should you do?
Move your contact to another frequency
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
B-002-04-09:
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?
Approximately 3 kHz
150 to 500 Hz
Approximately 6 kHz
Approximately 10 kHz
B-002-04-10:
What is a band plan?
A guideline for using different operating modes within an amateur band
A plan of operating schedules within an amateur band published by Industry Canada
A plan devised by a club to best use a frequency band during a contest
A guideline for deviating from amateur frequency band allocations
B-002-04-11:
Before transmitting, the first thing you should do is:
listen carefully so as not to interrupt communications already in progress
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
