HAM Radio also known as Amateur Radio is communication on designated bands for non-commercial use.   Ham radio also known as amateur radio is communication on designated bands for non-commercial use.  The ARRL is an organization that helps to organize ham radio.  The American Radio Relay League (ARRL) is the largest membership association of amateur radio enthusiasts in the USA. ARRL is a non-profit organization, and was founded in 6th April 1914 by Hiram Percy Maxim. According to the ARRL, ham Radio is, "''a popular hobby and service that brings people, electronics and communication together. People use ham radio to talk across town, around the world, or even into space, all without the Internet or cell phones. It's fun, social, educational, and can be a lifeline during times of need.''" Radio Amateurs (hams) provide, on a volunteer basis, '''public service, emergency, and disaster relief communications''' using radio stations located in their residences. Their services cost taxpayers nothing. They are provided at no cost to any served agency or to any government entity. FEMA has stated that when Amateur Radio operators are needed in an emergency or disaster, they are ''really'' needed.  At the center of ham radio is the practical experimentation to further the science and our understanding of radio communication. Individuals may pursue an interest in ham radio to communicate with others around the word while others may find experimenting with radio technology, both emerging and existing, to be the driving force for their interest.  Although called "Amateur Radio," there are many ham operators that are experts in radio communication.  It was the original members of ham radio that discovered and developed much of what is involved in radio communication today, including your "smart" phone and computer wireless technology.   Ham operators are allowed limited slices of many frequency bands across the radio spectrum which are allocated by the FCC.  Some ham radio operators use the very reliable Morse code, while others use voice, digital, and other modes.  At one time it was required to study and learn Morse code to get a ham radio license.  This is no longer the case, although Morse code is very useful for emergency communication and still where most contacts are made during the annual Field Day exercise. '''Part 97''' is the section of Federal Communications Commission (FCC) rules and regulations that pertains to amateur radio and the conduct of amateur radio operators. It is a part of the [[FCC Title 47 of the CFR]] (Code of Federal Regulations).  All Amateur Radio operations are subject to the Part 97 rules. == sample test questions ==== Getting Your ham License == To obtain an amateur radio license from the FCC you must attend a VE testing session and successfully pass an examination.  Furthermore... {{:Template:Sparse Entry}} === sample test questions ====== Technician Class ===== What's Happening in Ham Radio == === Field Day === Field Day is an annual amateur radio exercise where ham operators attempt to work as many stations as possible on any and all amateur bands (excluding the 60, 30, 17, and 12-meter bands) and to learn to operate in abnormal situations in less than optimal conditions.  Field Day helps to build emergency communications preparedness among amateur radio operators.  Field Day is always the fourth full weekend of June, beginning at 1800 UTC Saturday and running through 2059 UTC Sunday.Q: What does the abbreviation FET stand for?Field Day stresses emergency preparedness. Frequently, entire radio clubs get involved and assemble a portable radio station in a field or park. Some might use quickly deployable portable antennas while other might erect more elaborate radio masts and towers supporting several antennas. Generators or solar power provide electricity to amateur radio transceivers, which may be located in tents, cars, recreational vehicles, or other portable shelters.:A: Field Effect TransistorQ: What electrical component stores energy in an electric field?Field Day is open to all amateurs in the areas covered by the ARRL/RAC Field Organizations and countries within IARU Region 2.:A: CapacitorQ: What is meant by the term 'check' in reference to a formal traffic message?* [http://www.arrl.org/field-day ARRL Field Day]:A: The check is a count of the number of words or word equivalents in the text portion of the message.Q: What is meant by the term 'knife edge' propagation?=== VHF/UHF FM Simplex Calling Frequencies ===:A: Signals are partially refracted around solid objects exhibiting sharp edges.Q: What is the characteristic appearance of a cold solder joint?* 146.52x Mhz - 2-meter national simplex frequency for calling:A: A grainy or dull surface.* 223.50x Mhz - 1.25-meter national simplex frequency for calling* 446.0xx Mhz - 70-cm national simplex frequency for calling* 906.5xx Mhz - 33-cm national simplex frequency for calling* 1294.500x Mhz - 23-cm national simplex frequency for callingQ: What causes 'spin fading' when referring to satellite signals?:A: Rotation of the satellite and its antennas.Q: What is the term used to describe the use of a aub-audible tone transmitted with normal voice audio to open the squelch of a receiver?:A: CTCSSQ: Why is coaxial cable used more often than any other feedline for amateur radio antenna systems?[[Category:Electronics]]:A: It is easy to use and requires few special installation considerations.[[Category:Radio]][[Category:ham Radio]]
