Which of the following are typical duties of a Net Control Station?

  • Choose the regular net meeting time and frequency
  • Ensure that all stations checking into the net are properly licensed for operation on the net frequency
  • Correct Answer
    Call the net to order and direct communications between stations checking in
  • All these choices are correct

An amateur radio net is an "on-the-air" gathering of amateur radio operators. Most nets meet on a regular schedule and specific frequency, and are organized for a particular purpose, such as relaying messages, discussing a common topic of interest, sharing information during severe weather (for example, during a SkyWarn activation), during emergencies, or simply as a regular gathering of friends for conversation.

A formal, or directed, net has a single Net Control Station (NCS) that manages its operation for a given session. The NCS operator calls the net to order at its designated start time, periodically calls for participants to join, listens for them to answer (or check in), keeps track of the roster of stations for that particular net session, and generally orchestrates the operation of the net.

A different station might be the designated Net Control Station for each net session. The overall operation and scheduling of NCS assignments and net sessions is managed by the net manager. While Net Control Station operators will ask participants who check in for specific identifying information (such as callsign, name, and location) in order to create the net roster, Net Control Stations are not responsible for verifying the status of each participant's amateur radio license.

What technique is used to ensure that voice messages containing unusual words are received correctly?

  • Send the words by voice and Morse code
  • Speak very loudly into the microphone
  • Correct Answer
    Spell the words using a standard phonetic alphabet
  • All these choices are correct

Phone means voice. The phonetic alphabet is generally understood by operators in all countries, so using it enhances communication in identifying your station.

What is RACES?

  • An emergency organization combining amateur radio and citizens band operators and frequencies
  • An international radio experimentation society
  • A radio contest held in a short period, sometimes called a “sprint”
  • Correct Answer
    An FCC part 97 amateur radio service for civil defense communications during national emergencies

RACES stands for "Radio Amateur Civil Emergency Services." It was created by FEMA and the FCC, requires an Amateur Radio license for membership, and requires certification via a civil defense agency.

[Exam Tip] - Remember that the answer contains the words "civil" and "emergencies," which are the 'C' and 'E' in "RACES."

What does the term “traffic” refer to in net operation?

  • Correct Answer
    Messages exchanged by net stations
  • The number of stations checking in and out of a net
  • Operation by mobile or portable stations
  • Requests to activate the net by a served agency

Traffic refers to formal messages exchanged by net stations.

An amateur radio net or ham net is an on-the-air gathering of amateur radio operators. But there are different types of nets with different levels of formality and different purposes.

Traffic nets operate primarily to relay formal written messages.

What is the Amateur Radio Emergency Service (ARES)?

  • Correct Answer
    A group of licensed amateurs who have voluntarily registered their qualifications and equipment for communications duty in the public service
  • A group of licensed amateurs who are members of the military and who voluntarily agreed to provide message handling services in the case of an emergency
  • A training program that provides licensing courses for those interested in obtaining an amateur license to use during emergencies
  • A training program that certifies amateur operators for membership in the Radio Amateur Civil Emergency Service

According to the American Radio Relay League (ARRL),

The Amateur Radio Emergency Service (ARES) consists of licensed amateurs who have voluntarily registered their qualifications and equipment, with their local ARES leadership, for communications duty in the public service when disaster strikes.

By this statement, it's clear that ARES is not meant strictly for members of the military. Furthermore, because ARES assumes a membership of licensed amateurs, it is not intended for those interested in obtaining licenses.

Finally, ARES can indeed be a training program to help promote readiness certifications, but the Radio Amateur Civil Emergency Service (RACES) certifies its own membership (FCC Part 97 section 407.)

Which of the following is standard practice when you participate in a net?

  • When first responding to the net control station, transmit your call sign, name, and address as in the FCC database
  • Record the time of each of your transmissions
  • Correct Answer
    Unless you are reporting an emergency, transmit only when directed by the net control station
  • All these choices are correct

Remember that the "net control station" controls (directs) the conversation on a net. They will ask for check-ins, ask if there is any station with traffic, and guide the conversation based on the purpose of the net. A net may be social, or it may be activated during emergencies to provide supplemental communications between stations in the field and, say an EMA station, for example. Given this, it makes sense that you should listen to the control station and follow their directions.

Which of the following is a characteristic of good traffic handling?

  • Correct Answer
    Passing messages exactly as received
  • Making decisions as to whether messages are worthy of relay or delivery
  • Ensuring that any newsworthy messages are relayed to the news media
  • All these choices are correct

A station passing a message in an emergency has an expectation that it will be delivered, not weighed to see if it merits delivery or relay. So you're expected to deliver it.

You might think you know enough to clarify, abbreviate or otherwise change a message, but it's so risky that you should just not do it - pass the message exactly as received.

Emergency messages should always specify an originating party and the party to whom the message should be delivered. The choice about communicating messages to the news media for broadcast is generally not a good idea, unless that's the destination that was specified.

So the best answer is to pass the message exactly as received.

Are amateur station control operators ever permitted to operate outside the frequency privileges of their license class?

  • No
  • Yes, but only when part of a FEMA emergency plan
  • Yes, but only when part of a RACES emergency plan
  • Correct Answer
    Yes, but only in situations involving the immediate safety of human life or protection of property

This is a bit of a trick question; emergency plans will never take into account transmitting out of band, since if you're planning it you can always plan to not need to transmit out of band.

The rule is this: Always do whatever it takes to keep people safe. If someone is going to die unless you transmit on a police (or other) frequency, transmit first and ask forgiveness later.

Just make sure that whatever action you're taking isn't interfering with something and causing more danger than you are trying to protect against!

What information is contained in the preamble of a formal traffic message?

  • The email address of the originating station
  • The address of the intended recipient
  • The telephone number of the addressee
  • Correct Answer
    Information needed to track the message

The American Radio Relay League was originally created in order to relay messages across long distances. In order to do so safely and efficiently, the Amateur Radio Traffic Handling system was created. The first part of any message sent across this system is called the preamble.

The preamble contains information such as who the message is from, who the message is to, and information about the content of the message (specifically the number of words). This information is used to facilitate correctly routing the message through the Amateur Radio Traffic Handling System without losing any part of the message or sending it to the wrong destination.

What is meant by “check” in a radiogram header?

  • Correct Answer
    The number of words or word equivalents in the text portion of the message
  • The call sign of the originating station
  • A list of stations that have relayed the message
  • A box on the message form that indicates that the message was received and/or relayed

The best practice is to use plain English and not jargon. But in the case of formal message traffic, the word, "check" means the count of words in the body (text portion) of the message.

This is a way to make sure you didn't add or drop a word from the message. This is related to the best practice of passing the message exactly as it was received.

Let’s use this as an example message we want to send:

Great seeing you yesterday. Hope to get together again soon. 73

In a radiogram, periods are written as either the letter X (“initial x-ray”), or the word XRAY. Either way, this indicates an end of a sentence. Similarly, if your message was, “How are you?” the question mark would be written as QUERY to indicate a question.

Using this method, we will write the text of the message like this:

GREAT SEEING YOU YESTERDAY X

HOPE TO GET TOGETHER AGAIN

SOON 73

Notice how we did not place X between SOON and 73? When wishing someone 73 at the end of a message, we generally do not include an X as it’s automatically implied. The only exception would be to include it for clarity. For example, if the end of your message was “ON AUGUST 10 73” it could be confusing this way, so we would instead say “ON AUGUST 10 X 73” to help better separate the date from wishing someone 73.

Items like X and QUERY count as a word when filling in the check, so counting what we have above, there are 12 words, and we would write 12 in the check.
