FCC Technician Exam Question Of The Day (T2B07)

Q) What should you do if you receive a report that your station’s transmissions are causing splatter or interference on nearby frequencies?

A) Check your transmitter for off-frequency operation or spurious emissions


NJ2X Notes:
"Splatter" on SSB transmissions is high-order intermodulation distortion (IMD) caused by gross overdriving.  A transmitter will generate IMD if it is driven too hard.  It is important to make sure that overdriving never happens with your transmitter or amplifier.

FCC Technician Exam Question Of The Day (T2B09)

Q) Which of the following methods is encouraged by the FCC when identifying your station when using phone?

A) Use of a phonetic alphabet


NJ2X Notes:
Amateur radio operators often use the phonetic alphabet when transmitting their call via phone. It is good idea to practice and memorize the phonetic alphabet since you will encounter it often.   By the way, why isn't "phonetic" spelled that way? :-)

FCC Technician Exam Question Of The Day (T1B06)

Q) Which 23 cm frequency is authorized to a Technician Class operator license?

A) 1296 MHz

NJ2X Note:
You can memorize this answer.  Alternatively, you can learn and apply the underling theory which will help you beyond the test.   The relationship between a radio signal's frequency and its wavelength is described by the following formula:

wavelength in meters = 300 / frequency in MHz

FCC Technician Exam Question Of The Day (T1B08)

Q) What do the FCC rules mean when an amateur frequency band is said to be available on a secondary basis?

A) Amateurs may not cause harmful interference to primary users.


NJ2X Note:
A good example of a band available to amateurs on a secondary basis is 60m.

FCC Technician Exam Question Of The Day (T1B09)

Q) Why should you not set your transmit frequency to be exactly at the edge of an amateur band or sub-band?

A) All the following are correct.
- To allow for calibration error in the transmitter frequency display.
- So that modulation sidebands do not extend beyond the band edge
- To allow for transmitter frequency drift


Note from NJ2X: You definitely do not want to transmit outside the amateur radio bands since it is illegal.  However, this is exactly what will happen if you are transmitting on a frequency that is at the very edge of one of the amateur radio bands.  That is because all modes of communication use a certain amount of bandwidth so your radio is transmitting over a frequency range and not just the frequency you are tuned to.

For example, when transmitting on upper side band on 28.500Mhz the frequency range would extend up to 28.500Mhz + 3Khz.  Technician privileges end at 28.500Mhz so any voice transmission above this frequency would be illegal if made by a technician lice…

FCC Technician Exam Question Of The Day (T1C06)

A) Transmissions that contain obscene or indecent words or language.

NJ2X Note:
Amateur radio is no place for bad language.  The hobby is enjoyed by families, the young and elderly, - mothers, fathers, sisters, brothers, uncles, aunts, and grandparents alike.  Don't say anything you would not want printed in the Sunday newspaper, read to your mother, and attributed to you.  It is also important to be your best while operating.  That is because your behavior on the air is a matter of national pride and the world is listening.  Like it or not, we are all international ambassadors representing our great nation.

FCC Technician Exam Question Of The Day (T1B10)

Q) Which of the bands available to Technician Class operators have mode-restricted sub-bands?

A) The 6 meter, 2 meter, and 1.25 meter bands.

NJ2X Note:
These mode-restricted sub-bands are reserved for CW operations only.

FCC Technician Exam Question Of The Day (T1B07)

Q) What amateur band are you using if you are transmitting on 223.50 MHz?

A) 1.25 meter band

NJ2X Note:
You can memorize this answer.  Alternatively, you can learn and apply the underling theory which will help you beyond the test.  The relationship between a radio signal's frequency and its wavelength is described by the following formula:

wavelength in meters = 300 / frequency in MHz

In the example above, wavelength = 1.34m = 300 / 223.50Mhz.  On the test, the closest answer to the calculated wavelength is the 1.25m band.

FCC Technician Exam Question Of The Day (T1E05 )
