General class control operator frequency privileges; primary and secondary allocations
On which HF/MF bands is a General class license holder granted all amateur frequency privileges?
  • 60 meters, 20 meters, 17 meters, and 12 meters
  • 160 meters, 80 meters, 40 meters, and 10 meters
  • 160 meters, 60 meters, 30 meters, 17 meters, 12 meters, and 10 meters
  • 160 meters, 30 meters, 17 meters, 15 meters, 12 meters, and 10 meters

The key word here is ALL. The easiest way to get this one right is to eliminate distracters. General License holders do not have full privileges on the 80, 40, 20, and 15 meter bands.

As a mnemonic: 80 halved is 40, which halved is 20. And 8 + 4 + 2 is... almost 15.

On which of the following bands is phone operation prohibited?
  • 160 meters
  • 30 meters
  • 17 meters
  • 12 meters

The 30 meter band is special in a number of ways. It only allows data modes (so no phone), there's a power limit (200 Watts PEP), and contesting is not allowed.

Propagation is usually good during the day and excellent during the night, so it can be a great band for CW or digital DX contacts.

On which of the following bands is image transmission prohibited?
  • 160 meters
  • 30 meters
  • 20 meters
  • 12 meters

(B). The FCC has restricted the 30 meter band to only data transmission modes (such as CW, RTTY and packet), so image transmission is prohibited. Image transmissions are found within phone transmission band segments rather than data. Image transmission is prohibited on the 60 meter band as well, where we are restricted to 5 specific frequency channels for SSB phone communication only.

Which of the following amateur bands is restricted to communication only on specific channels, rather than frequency ranges?
  • 11 meters
  • 12 meters
  • 30 meters
  • 60 meters

(D). The 60 meter band is a shared frequency range where the government has primary rights and amateur radio is restricted to communicating as a secondary service only on specific channels. This is to keep the possibility of signal interference at a minimum.

Which of the following frequencies is in the General class portion of the 40-meter band (in ITU Region 2)?
  • 7.250 MHz
  • 7.500 MHz
  • 40.200 MHz
  • 40.500 MHz

In the 40 meter band the following ranges are available to holders of a General Class license:

  • 7.025-7.125 MHz (CW, RTTY, data)
  • 7.175-7.300 MHz (CW, phone, image)

If you use the wavelength to calculate the approximate frequencies for the 40 meter band (300m/40m), you will get 7.5 MHz, but 7.5 MHz falls just outside of the band.

Refer to FCC Section: [97.301(d)]

See the ARRL website for a full overview of frequency allocations (pdf, text).

Which of the following frequencies is within the General class portion of the 75-meter phone band?
  • 1875 kHz
  • 3750 kHz
  • 3900 kHz
  • 4005 kHz

The general class portion of the 75 meter phone band is from 3.800 to 4.000 MHz (3800 to 4000 kHz), so the anwer 3900 kHz falls within this range.


Note:
If we calculate frequency from wavelength using \(f = \frac{300}{\lambda}\), we get \[f = \frac{300}{75\text{ meters}} = 4\text{ MHz} = 4000\text{ kHz}\]

We need to remember that this is at the end of the \(75\text{ meter}\) range, so answer \(4005\text{ kHz}\) is out of bounds. You can double-check yourself by reversing the calculation: Given \(4005\text{ kHz}\), the wavelength = \(\frac{300}{f} = \frac{300}{4.005} = 74.9\text{ m}\), so we can see this is out of the 75-80 range.

If we do the same for \(3750\text{ kHz}\), wavelength = \(\frac{300}{3.750} = 80\text{ m}\), so that is not going to be in the phone range of this band.

Answer \(3900\text{ kHz}\) gives us a wavelength of \(\frac{300}{3.900} = 76.9\text{ m}\), so that is nicely in our \(75\text{ m}\) band range.

By reading the chart (linked below), you'll see that \(3900\text{ kHz}\) is listed under \(80\text{ meters}\) band. General-class license holders have access from \(3.8\) to \(4.0\text{ MHz}\) at \(200\text{ W}\).

Which of the following frequencies is within the General class portion of the 20-meter phone band?
  • 14005 kHz
  • 14105 kHz
  • 14305 kHz
  • 14405 kHz

(C). The General class has privileges on the 20 meter band for CW/Data from 14.025-14.150 MHz and for phone (which this question involves) from 14.225-14.350 MHz. Even though all of these frequencies are close, only (C) 14305 kHz falls within the phone portion of the band.

Note: Here the frequencies are close enough that the calculation f = 300/wavelength is not going to be useful as f = 300/20 = 15. So you will want to remember that the phone privileges have a higher frequency (shorter wavelength) within each band than the CW/data section, and that 14.350 is the upper limit for this band, so you want the value that lies just below this limit.

Which of the following frequencies is within the General class portion of the 80-meter band?
  • 1855 kHz
  • 2560 kHz
  • 3560 kHz
  • 3650 kHz

General class operators may operate within two sub-bands within the 80m band:

(C). The General class portion of the 80 meter band is from 3.525-3.600 MHz, and 3.8-4.0 MHz.

Only answer 3560 kHz falls within this range.

The lower frequency range (3.525-3.600 MHz) may be used for CW, RTTY, and data transmissions. The higher range (3.8-4.0 MHz) may be used for phone and image.

3560 kHz falls within the range allocated for CW/RTTY/data. 3650 kHz looks close, but it’s actually in the gap between the two sub-bands allowed for General class operators.

Memorize 3.6 MHz as the upper end of the data sub-band and pick the answer that is slightly lower, not higher, than that.

Which of the following frequencies is within the General class portion of the 15-meter band?
  • 14250 kHz
  • 18155 kHz
  • 21300 kHz
  • 24900 kHz

General class privileges let us use the ranges of 21.025-21.200 MHz (CW/data) and 21.275-21.450 MHz (phone), so the answer 21300 kHz falls within the phone range of the 15 meter band.

Note: Remember that the 15 meter band actually is located below 15 meters (from λ=300/21.450 MHz =13.98 m to λ=300/21.025 MHz=14.27 m). If you remember this and check the wavelength of the 2 values that are close (18155) and (21300), you will find that (18155) gives a wavelength = 300/18.155 MHz = 16.52m, whereas (21300) gives you a value of wavelength = 300/21.300 = 14.08.

If you estimate 300/15 = 20, you'd have 50% correct. So just remember it's a bit above this number which is 21.

Which of the following frequencies is available to a control operator holding a General class license?
  • 28.020 MHz
  • 28.350 MHz
  • 28.550 MHz
  • All these choices are correct

(D). All of these frequencies are within the privileges for operators holding a general class license, so (D) All of these choices are correct. The band privileges for 28 MHZ (10 meters) are from 28.000 MHz all the way up to 29.700 MHz!

When General class licensees are not permitted to use the entire voice portion of a band, which portion of the voice segment is generally available to them?
  • The lower frequency end
  • The upper frequency end
  • The lower frequency end on frequencies below 7.3 MHz, and the upper end on frequencies above 14.150 MHz
  • The upper frequency end on frequencies below 7.3 MHz, and the lower end on frequencies above 14.150 MHz

(B). The general rule is that if sections of a band are split between voice and data, that the upper frequency end of the band is used for voice and the lower frequency end is used for CW/data.

Which of the following applies when the FCC rules designate the Amateur Service as a secondary user on a band?
  • Amateur stations must record the call sign of the primary service station before operating on a frequency assigned to that station
  • Amateur stations can use the band only during emergencies
  • Amateur stations can use the band only if they do not cause harmful interference to primary users
  • Amateur stations may only operate during specific hours of the day, while primary users are permitted 24- hour use of the band

(C). As amateurs, we must always follow the rules of COURTESY. In a case where the Amateur Service has been designated as a secondary user (such as on 30 and 60 m bands) this is even more important. Amateur stations are allowed to use the band ONLY if they do NOT cause harmful interference to primary users. Listen First! If you hear another transmission, do not use that frequency. If you hear a primary user come on to the same frequency that you are working or nearby frequency, immediately move your transmission farther away so that you will not interfere with their signal.

What is the appropriate action if, when operating on either the 30-meter or 60-meter bands, a station in the primary service interferes with your contact?
  • Notify the FCCs regional Engineer in Charge of the interference
  • Increase your transmitter's power to overcome the interference
  • Attempt to contact the station and request that it stop the interference
  • Move to a clear frequency or stop transmitting

(D). As Amateur Radio operators we must always follow the rules of COURTESY. In a situation where Amateur Radio has secondary privileges, such as the 30 or 60 meter bands, this is even more important. We are allowed to use the frequency only if we do not cause interference to primary users. Listen first! If a primary user is already using the frequency, or starts using the same or a nearby frequency, then immediately move to a clear frequency to avoid causing interference.

Which of the following may apply in areas under FCC jurisdiction outside of ITU Region 2?
  • Station identification may have to be in a language other than English
  • Morse code may not be permitted
  • Digital transmission may not be permitted
  • Frequency allocations may differ

Due to ITU regions and band plans the limits of the frecuencies and the band edges may be placed in different numbers. We have to remember that some U.S. territories are in ITU Region 3

What portion of the 10-meter band is available for repeater use?
  • The entire band
  • The portion between 28.1 MHz and 28.2 MHz
  • The portion between 28.3 MHz and 28.5 MHz
  • The portion above 29.5 MHz

47 CFR 97.205 regulates repeaters generally, it prohibits repeaters on the 28.0-29.5 MHz portion of the 10-meter band.
