COMMISSION RULES

Section E1A

Frequency privileges; signal frequency range; automatic message forwarding; stations aboard ships or aircraft; power restriction on 630- and 2200-meter bands

Why is it not legal to transmit a 3 kHz bandwidth USB signal with a carrier frequency of 14.348 MHz?

  • USB is not used on 20-meter phone
  • The lower 1 kHz of the signal is outside the 20-meter band
  • 14.348 MHz is outside the 20-meter band
  • Correct Answer
    The upper 1 kHz of the signal is outside the 20-meter band

Upper Side-Band signals extend upwards (in frequency) from the carrier frequency -- thus if you transmit an upper-sideband signal that is 3 kHz wide on 14.348 MHz it will extend from 14.348 MHz to 14.351 MHz.

The 20 meter band extends from 14.000 MHz to 14.350 MHz, so the upper 1 KHz of the signal is above 14.350 MHz and thus you would be illegally transmitting out of band.

When using a transceiver that displays the carrier frequency of phone signals, which of the following displayed frequencies represents the lowest frequency at which a properly adjusted LSB emission will be totally within the band?

  • The exact lower band edge
  • 300 Hz above the lower band edge
  • 1 kHz above the lower band edge
  • Correct Answer
    3 kHz above the lower band edge

Test Tip: With all of these types of questions the correct answer begins with "3 kHz"

The SSB take up approximately 3khz of bandwidth for Lower Side Band (LSB) so you need to tune the radio 3khz above the lower edge so you will not be transmitting outside of your bandwidth privileges.

What is the highest legal carrier frequency on the 20-meter band for transmitting a 2.8 kHz wide USB data signal?

  • 14.0708 MHz
  • 14.1002 MHz
  • Correct Answer
    14.1472 MHz
  • 14.3490 MHz

The top of the data portion of the 20-meter band is 14.150 MHz. Our entire transmission needs to fall below this frequency. Because we are using Upper Sideband and 2.8 kHz Bandwidth, our signal occupies the spectrum from 0 - 2.8kHz above the selected carrier frequency.

Therefore, to keep our transmission below 14.150 MHz, the maximum carrier frequency is 14.150 MHz - 2.8 kHz or 14.1472 MHz.

Silly hint: look for the repetition, 14.1472 And remember that 14 is half of 28 (“2.8 kHz wide”).

May an Extra class operator answer the CQ of a station on 3.601 MHz LSB phone?

  • Yes, the entire signal will be inside the SSB allocation for Extra class operators
  • Yes, the displayed frequency is within the 75-meter phone band segment
  • Correct Answer
    No, the sideband components will extend beyond the edge of the phone band segment
  • No, US stations are not permitted to use phone emissions below 3.610 MHz

Remember that your actual signal extends to either side of the frequency you are transmitting on. A Lower Side Band (LSB) transmission is considered to have 3 kHz of bandwidth below the carrier, so you should set your carrier at least 3 kHz higher than the lower edge of the 80 meter band's voice portion when operating LSB.

The lower limit for phone in the 3MHz (80 meter) band is 3.600 MHz, so the sideband of your signal if you transmit on 3.601 Mhz could easily go below 3.600 MHz and you would be transmitting in a part of the band where phone is not allowed.

Who must be in physical control of the station apparatus of an amateur station aboard any vessel or craft that is documented or registered in the United States?

  • Only a person with an FCC Marine Radio license grant
  • Only a person named in an amateur station license grant
  • Correct Answer
    Any person holding an FCC issued amateur license or who is authorized for alien reciprocal operation
  • Any person named in an amateur station license grant or a person holding an unrestricted Radiotelephone Operator Permit

The rules for operating an amateur radio station aboard a vessel or craft in the US are roughly the same as the rules governing any other station in the United States.

Specifically, the control operator (the person in physical control of the station apparatus) must either hold a valid FCC-issued amateur radio license or they must be authorized for alien reciprocal operation -- that is, they can operate if they are an alien (non-US citizen) holding a license in a country with whom the US has a reciprocal operating agreement allowing them to operate in the United States with their alien amateur radio license.

Goofy hint: ”control” is in the question, and ”aliens” is in the correct answer. In sci-fi movies, the aliens always try to take control of Earth.

What is the required transmit frequency of a CW signal for channelized 60 meter operation?

  • At the lowest frequency of the channel
  • Correct Answer
    At the center frequency of the channel
  • At the highest frequency of the channel
  • On any frequency where the signal’s sidebands are within the channel

All signals transmitted by an amateur on 60 meter channels must be centered within the channel.

Memory Aid: Think "sixty-center"

What is the maximum power permitted on the 2200-meter band?

  • 50 watts PEP (peak envelope power)
  • 100 watts PEP (peak envelope power)
  • Correct Answer
    1 watt EIRP (equivalent isotropic radiated power)
  • 5 watts EIRP (equivalent isotropic radiated power)

This is a memory item.

2200M is the lowest band on the band plan. The correct answer has the lowest wattage.

See: http://www.arrl.org/images/view//Charts/Band_Chart_Image_for_ARRL_Web.jpg

TEST TIP: For this question, and associated question E1A14, when trying to remember the power limits for the two lowest amature bands, the LOWEST BAND (2200M) gets the LOWEST POWER (1W) while the SECOND-LOWEST BAND (630M) gets the SECOND-LOWEST POWER option (5W).

If a station in a message forwarding system inadvertently forwards a message that is in violation of FCC rules, who is primarily accountable for the rules violation?

  • The control operator of the packet bulletin board station
  • Correct Answer
    The control operator of the originating station
  • The control operators of all the stations in the system
  • The control operators of all the stations in the system not authenticating the source from which they accept communications

Message forwarding systems are just that -- systems that forward messages.

While control operators of message forwarding stations are expected to do what is reasonable to prevent incorrect use of their station, the primary responsibility for the contents of a message still belongs to the station that sends the original message.

Except in some parts of Alaska, what is the maximum power permitted on the 630-meter band?

  • 50 watts PEP (peak envelope power)
  • 100 watts PEP (peak envelope power)
  • 1 watt EIRP (equivalent isotropic radiated power)
  • Correct Answer
    5 watts EIRP (equivalent isotropic radiated power)

This is a memory item, see the ARRL Band Plan Chart

TEST TIP: For this question, and associated question E1A07, when trying to remember the power limits for the two lowest amateur bands, the LOWEST BAND (2200M) gets the LOWEST POWER (1W) while the SECOND-LOWEST BAND (630M) gets the SECOND-LOWEST POWER option (5W).

If an amateur station is installed aboard a ship or aircraft, what condition must be met before the station is operated?

  • Correct Answer
    Its operation must be approved by the master of the ship or the pilot in command of the aircraft
  • The amateur station operator must agree not to transmit when the main radio of the ship or aircraft is in use
  • The amateur station must have a power supply that is completely independent of the main ship or aircraft power supply
  • The amateur station must operate only in specific segments of the amateur service HF and VHF bands

Just remember that on a ship or plane the captain is in charge. That could be the captain/master of a seagoing vessel or the captain/pilot of an airplane. In either case you should not use an amateur radio station without permission from the captain.

Also, this is the only question with the words "master" or "approved".

What licensing is required when operating an amateur station aboard a US-registered vessel in international waters?

  • Any amateur license with an FCC Marine or Aircraft endorsement
  • Correct Answer
    Any FCC-issued amateur license
  • Only General class or higher amateur licenses
  • An unrestricted Radiotelephone Operator Permit

Amateur Radio stations aboard a US-registered vessel in international waters are under the same guidelines as any station on US soil. You need a FCC-issued ham license or a reciprocal permit for an alien amateur license (meaning a license from another country) to operate your license on US soil, so you need that on a US-registered vessel as well.
