How is HAM radio different from a common radio?
Ham radio is for amateur radio enthusiasts and operates in a different frequency spectrum that broadcast radio. Ham radio operators are allowed to transmit and communicate with other radio operators around the world, depending on atmospheric conditions, and their communications can be that of Morse code, voice and even slow scan television. A license is generally required to operate a ham transmitter. receiver (commonly referred to as a `transceiver' and the transmitting power can vary. One of the favorite things ham operators will do, is try to operate on `flea-power', meaning that they try to make world wide communications links with another ham radio operator, based on as little as 100 milliwatts. That's 1/10th. of a watt of transmitting power. Then they will usually send a postcard from to each other, verifying the date, time and other conditions of their communications to each other. I believe this is commonly referred to as `DX-ing'. You can spend as little or as much as you wish on your communications equipment and many ham operators actually construct their equipment. Although I;'m not involved in ham radio, it can be an exciting and fun hobby for those involved.

Ham Radio also known as Amateur Radio, is a service and hobby enjoyed by radio enthusiasts around the world. Hams use radio equipment to communicate all over the world. A lice…nse is required to operate a ham radio. More information is available from the American Radio Relay League or you can search for a ham radio club in your area.
Ham radio operators use two-way radio stations from their homes, cars, boats and outdoors to make hundreds of friends around town and around the world. They communicate with e…ach other using voice, computers, and Morse code. Some hams bounce their signals off the upper regions of the atmosphere, so they can talk with hams on the other side of the world. Other hams use satellites. Many use hand-held radios that fit in their pockets.
Ham Radio is different then regular common radio in many different aspects. First you need a license to operate on ham (amateur) radio. A license is very easy to obtain and re…quires you to take a multiple choice exam. There is a nominal fee and the exam is administered by a VEC (Volunteer Exam Commissioner). However, you are able to use many different types of radio communication modes. Hams enjoy satelite communications, TV and digital communication, handheld and mobile voice as well as the traditional big box on the table with tons of knobs and meters on it. Hams are also allowed to legally use significantly more transmit power than Common Radio and are given access to many more usable frequencies than Common Radio.

Amateur radio, often called ham radio, is both a hobby and a service in which participants, called "hams," use various types of radio communications equipment to communicate w…ith other radio amateurs for public service, recreation and self-training. But we still don't know the origin of the word HAM.
Nobody is really sure, not even the authorities and old-timers in the hobby itself. The formal designation for that service is "Amateur Radio". One theory is that H.A.M. i…s an acronym paying homage to three great radio pioneers: Heinrich Hertz (demonstrated existence of electromagnetic waves), Edwin Armstrong (invented modern FM radio), and Guglielmo Marconi (developed wireless telegraphy). Another theory is when the first amateur radio operators where using CW (Morse Code), that they tended to have a "heavy" (hard) hand, and was called being "ham fisted". This tends to be the most common theory, by the ARRL. (KC0KM)
Net is short for network. It is a group of organized radio stations meeting on a set time/frequency to exchange information etc. For example, every night a 8:00 p.m. our club …runs a net where individuals tune into a set radio frequency to allow for announcements, messages or emergency information to be exchanged. By meeting each night on a schedule, if there was a disaster or failure of communications, each member would know that at least once per day there would be an set time/place to meet to get or send information to each other.
CB radio uses a frequency of 27 MHz and 49 MHz band. A FCC permit is required but no Morse code or electronic knowledge is required. Ham radio is a FCC licensed area which req…uires various degrees of electronic knowledge and in some cases Morse code proficiency. CB radio (citizen band radio) is restricted to voice communication only using commercially built radios. Ham or amateur radio covers a broad range of types of communication which includes but not limited to voice, Morse code, TV, teletype etc. The equipment used can be commercially built or homemade (as long as it meets FCC approval). Unfortunately the CB radio bands have been over used and very abused by many of its users and has become a FCC nightmare. The amateur radio bands are self policed by the license holders and abusers are reported to the FCC or in many cases tracked down by the hams and shut down. Ham radio operators take their privileges very seriously and abhor those who abuse the privilege.
Not necessarily. Normally, Ham Radio is used to describe amateur, 2 way radio where 2 individuals talk to each other back and forth; on the other hand, shortwave radio general…ly is used to describe commercial High Frequency radio broadcasting. This band is a commercial service that provides long range (worldwide) audiences for broadcasts but is a 1 way media. Think about a local FM radio show that you could listen to anywhere in the world but you can not talk back to them.
Once you have your Amateur License, you can buy a ham radio online, you can go to a local hamvention where vendors like icom and kenwood will be selling radios, you could go t…o a local radio club, I'm sure they'd be happy to sell you one of their old radios at a great price, or point you in the dirrection of a local ham shop.
The only disadvantage of ham radio is the one it shares with aviation, boating, philately, knitting, numismatics, WikiAnswers, bowling, billiards, and any other hobby or a…vocation with the capacity to become addictive ... the risk that the devotee will develop a pursuit, attachment, and habit so strong that it will make inordinate demands on his resources of time, attention, dedication, finances, and sociability.
Ham radio , owing to its social context, evolved, and is not a consumer product as is, perhaps a Walkie-Talkie. the technical editor ( he edited a variety of radio and electro…nics magazines- also science fiction stuff) Hugo Gernsback played indeed a big Brother, or Father Figure type role to the whole idea of Amateur Radio back in the days of the Key-only transmissions. When the federal government got to regulating radio transmission licensing, Gernsback and his magazines- Modern Electrics ,. for one, made a big push for non-profit amateur operators, their various utility roles, etc. and this was instrumental in getting the Federal Roberts Bill enacted. This was in the very early teens.as it was, there was a separation of categories of licensed ops- commercial, marine ( ships, etc) and Amateur, all on different frequencies and wavelengths to minimize interference- often called Harmonics by Radio buffs. In a sense Mr. Gernsback was one of the Founding fathers of Ham Radio, in the organizational sense, so to speak.
Yes Ham Radio and Amateur Radio are same. Amateur and Ham radio operators use two-way radio stations from their homes, cars, boats and outdoors to make hundreds of friends aro…und town and around the world. They communicate with each other using voice, computers, and Morse code. Some hams bounce their signals off the upper regions of the atmosphere, so they can talk with hams on the other side of the world. Other hams use satellites. Many use hand-held radios that fit in their pockets.
In the United States, you need to get an amateur operator license grant through the Federal Communications Commission (FCC). See Related Links for the process.
Somewhat oddly, and this also applies to another federally-monitored (Hobby) prospecting, there are no statutory age requirements. there have been ( most exceptionally) some a…dult-coached Hams as young as 8 in the fifties. There are different categories of exams for different classes of operators ( within the Ham envelope- this does not include C.B. ) some require code proficiency, some do not.
Yes and no. Some high power ham radios do not run on batteries, but use 12 volt power supplies. You can hook this up to a car battery and use that, but a higher power radio wi…ll exhaust its power quickly, so it is impractical. Smaller, handheld radios do run on batteries, and put out a lower power signal.
1. In amateur radio, you cannot broadcast except in a few specific instances. You can only transmit to another station or stations. 2. Amateur radio operators can operate on… a very wide spectrum of frequencies. Other services are limited to a narrow band of frequencies. 3. Amateur radio may never be used in selling anything. 4. In amateur radio, many modes can be used: phone (voice), code, teletype, digital packet, am, fm, sideband, television, and more.
