The purpose of the Amateur Radio Service, as stated in the FCC rules and regulations, is to encourage and promote the development of technical and communication skills in radio. This service is meant to advance the radio art, which includes experimenting with radio technology, improving communication techniques, and providing a pool of trained operators who can assist in emergencies. It also fosters international goodwill by connecting people from different countries through communication.

Amateur radio isn't just a hobby; it's a way to build technical expertise, contribute to public service, and enhance the global community through the responsible and innovative use of radio technology. Understanding this purpose helps operators appreciate their role and responsibilities within the broader context of radio communication.

The FCC (Federal Communications Commission) regulates and enforces the rules for amateur radio as part of its broader mission to manage the U.S. communications infrastructure. The FCC ensures that all users of the radio frequency spectrum, including amateur radio operators, adhere to rules that prevent interference, promote safety, and encourage the advancement of communication technologies.

In the context of amateur radio, the FCC's regulation ensures that operators use the spectrum responsibly, contributing to public service, especially during emergencies. By setting licensing requirements and operational standards, the FCC maintains order on the airwaves, allowing amateur radio to function effectively and safely within the larger communications landscape.

If you have trouble memorizing '97', look at the other questions on your test. There are several that have Part 97 as part of the question. For example, "What is the FCC Part 97 definition of a space station?" You may have one of these questions on the test and can use it to answer this one. Or one way to remember this question is that it is closest to 100.

Just remember ninety-seven NS = Nerd Socks

Harmful interference is exactly what it sounds like; any time you are using a radio and cause problems with another radio that is operating in a legal and correct manner, you are causing harmful interference.

Just memorize the Part 97 purposes for the Amateur Radio Service. You'll remember "Enhancing international goodwill" as one of the choices.

Amateur radio is not meant to provide inexpensive communications - there's nothing in Part 97 about that.

Amateur radio operators evolve efficient radio operating procedures - they might sound like military radio procedures because of the ITU Phonetic Alphabet, often used to clarify messages. But that's not the purpose of Amateur Radio.

Radionavigation is a critical service - losing navigation services in the middle of navigating could be fatal. Think about which of these is most critical - that's the right choice.

"tele" means remote, and "metry", from the same root as "metric", indictates "measurement." So, if a remote device sends measurements, such as temperature, it is transmitting telemetry data.

Thus, telemetry is essentially "Remote Measurement."

47 CFR 97.3(a)(22):

Frequency coordinator. An entity, recognized in a local or regional area by amateur operators whose stations are eligible to be auxiliary or repeater stations, that recommends transmit/receive channels and associated operating and technical parameters for such stations in order to avoid or minimize potential interference.

Frequency Coordinators are regular amateur radio operators who are selected by repeater operators to coordinate the use of the radio frequencies for a given geographical area. This is important to keep repeaters from interfering with each other and to ensure that enough frequencies remain usable for simplex operation.

Some people may think that any frequencies can be used for simplex operation, but if you are uninformed as to the band plan selected by the Frequency Coordinator in your area, you may find yourself operating on or close to the input frequency of a repeater, thus causing harmful interference to others in the area.

Part 97 defines an Amateur Station as: (5) Amateur station. A station in an amateur radio service consisting of the apparatus necessary for carrying on radio communications.

A station may be mobile, fixed, or handheld, and the definition makes no description of the person operating the equipment. In other words, no matter where the radio is being used from (Vehicle, House, Handheld) the Radio is the station.

Don't let the upper case letters used in the term "Amateur Radio Service" distract you.

To quote FCC rules Part 97 section 101,

(d) No amateur operator shall willfully or maliciously interfere with or cause interference to any radio communication or signal.

This FCC statement applies to radio communications, regardless of content, frequency, event, or time boundaries; therefore, the answer is At no time.

It is NEVER allowed to intentionally interfere with another amateur radio frequency.

By process of elimination:

"Broadcasting" is prohibited for Amateur Radio.

You can't charge for passing messages.

There's nothing in Part 97 about Amateur Radio existing to provide cheap communications for anyone, let alone a business, start-up or not!

The prefix "tele" means remote. Examples of telecommand would be sending a radio command to a radio controlled aircraft or even remote control of a repeater.

You could think of telecommand as another word for "remote control"
