General class control operator frequency privileges; primary and secondary allocations
On which HF and/or MF amateur bands are there portions where General class licensees cannot transmit?
  • 60 meters, 30 meters, 17 meters, and 12 meters
  • 160 meters, 60 meters, 15 meters, and 12 meters
  • Correct Answer
    80 meters, 40 meters, 20 meters, and 15 meters
  • 80 meters, 20 meters, 15 meters, and 10 meters

Only the Extra Class is permitted to transmit on the entirety of the HF and/or MF 80 meter, 40 meter, 20 meter, and 15 meter amateur bands.

Hint: An easy way to remember this, is to start at 80 and divide it by 2 to get 40, and then again to get 20. The answer will always be in this order, so you'll be able to pick it out easily.

Hint: The correct answer is the only answer that includes 40 meters, it's missing in all the incorrect answers.

On which of the following bands is phone operation prohibited?
  • 160 meters
  • Correct Answer
    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.

Refer to FCC Section: [97.305]

An easy way to remember this is that no one under the age of about 30 makes actual phone calls.

or

A similar silly mnemonic is, "never invite party- pooper 30 meters to a phone party!"

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

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.

HINT: “No IMG In the thirty”

Hint: NTSC Fast Scan video runs at 30 frames per second, which you'll want to remember if you take the Extra test. Video is not allowed on 30M (or 60M, same memory trick).

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

Remember: Using the "60m band" is like looking at your watch with 60 seconds. Amateurs are the "second" user with privledges, also you need to take a extra "second" to listen for ongoing traffic and not cause any interference.

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.

Silly Hint: Everybody wants more time (measured in 60-second minutes), so everybody wants 60 meters.

Refer to FCC Section: [97.303(s)]

On which of the following frequencies are General class licensees prohibited from operating as control operator?
  • Correct Answer
    7.125 MHz to 7.175 MHz
  • 28.000 MHz to 28.025 MHz
  • 21.275 MHz to 21.300 MHz
  • All these choices are correct

You are only allowed to operate in frequency spaces where your operation class allows you to do so.

The General class license allows transmission for voice between 7.175 MHz and 7.300 MHz but not between 7.125 and 7.175 MHz. However, both are allowed spaces for Advanced and Extra class operators.

28.000 MHz to 28.025 MHz and 21.275 MHz to 21.300 MHz are both allowed spaces to transmit on with a general class license.

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 may use the band only during emergencies
  • Correct Answer
    Amateur stations must not cause harmful interference to primary users and must accept interference from primary users
  • Amateur stations may only operate during specific hours of the day, while primary users are permitted 24-hour use of the band

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.

Hint: “DON’T interfere with the FCC!”

On which amateur frequencies in the 10-meter band may stations with a General class control operator transmit CW emissions?
  • 28.000 MHz to 28.025 MHz only
  • 28.000 MHz to 28.300 MHz only
  • 28.025 MHz to 28.300 MHz only
  • Correct Answer
    The entire band

FCC Regulations (§ 97.305(a)) specifically say:

  • Except as specified elsewhere in this part, an amateur station may transmit a CW emission on any frequency authorized to the control operator.

Currently, there are no specified exceptions to this rule.

Recalling that a General class operator has full access to the 10-meter band, it follows that a General class operator may therefore transmit CW on the entire band.

Just remember that, as an Amateur, CW is always allowed if you are authorized on that frequency.

Hint: They got the “WHOLE” band back together.

Which HF bands have segments exclusively allocated to Amateur Extra licensees?
  • All HF bands
  • Correct Answer
    80 meters, 40 meters, 20 meters, and 15 meters
  • All HF bands except 160 meters and 10 meters
  • 60 meters, 30 meters, 17 meters, and 12 meters

This information is located in operating band plans.

Hint: The class AE contains the 1st and 5th letter of the alphabet and only the correct answer contains the number 15.

Which of the following frequencies is within the General class portion of the 15-meter band?
  • 14250 kHz
  • 18155 kHz
  • Correct Answer
    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.

Silly memory aid: 2 x 15 = 30.
21300 is the only answer with the numbers 2 and 30.

Even more silly: Only answer that adds up to 15 2+13

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
  • Correct Answer
    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.

Hint: 300 ÷ 10 = 30 MHz. The correct answer is the one closest to 30.

Mnemonic: Libby's Libby's Libby's repeats and L is 5 in the Major System. 295 is nibble in the Major System. Libby's Libby's Libby's cans nibble corn. Nibble some Libby's.

Hint: Repeaters are on high spots and the answer is the highest frequency.

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

Central portions of any band are preferred over the end portions because most antennas sport a usable BW that tends to be less than the BW of the band they are designed for. Thus the antenna used will have a lower SWR towards the center of the band than towards the ends to allow for a reasonable SWR across the entire band. Amateur Extra class operators have privileges over all other operator classes, thus if a portion of the phone allocation in a band is reserved for the exclusive use of Amateur Extra operators, then it will be the portion of the band towards the center for the benefit of the lower SWR and not towards the upper end where antennas generally sport a higher SWR. Therefore it follows that if General class operators aren't able to use the portion of a phone allocation towards the center of a band they will be relegated to using the phone portion towards the top end.


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.
