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.

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 communi…cate with other radio amateurs for public service, recreation and self-training. Amateur radio operators enjoy personal (and often worldwide) wireless communications with each other and are able to support their communities with emergency and disaster communications if necessary, while increasing their personal knowledge of electronics and radio theory. An estimated six million people throughout the world are regularly involved with amateur radio. The term "amateur" is not a reflection on the skills of the participants, which are often quite advanced; rather, "amateur" indicates that amateur communications are not allowed to be made for commercial or money-making purposes.
Ham radios are also called amateur radios. I am going to recommend you two ham radios and these are one of the best amateur radios in the market. SR-955 HPC and SR-655 H…PC are the best amateur radios. Below are some of the feature of SR-955 and SR-655. Have a high power radio, 7 color frequency display, dimmer control, its also clarifier and Pc programmable system. For Reference Google Strykerradios.
Dear Friend I bought 10 meter Ham Radio from Strikers Radio. Buy Ham Radio from Strikers Radio. Dear search this keyword in Google (Stryker Radios). You will find de…tails of near stores
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.
During disasters regular mode of communications, land phones, mobiles, are disrupted as the local infrastructure are destroyed. Ham radio can work on batteries or portab…le generators. Contacting the world outside the disaster zone becomes easy as there is always some other ham radio operator on-line who can relay the message and create a communication channel between the disaster zone and rescue / support services.
There is a long list of "Q-signals", used in place of common statements or phrases, that originated during the period when most communication was in the form of Morse Code. … 'QSL' means 'I confirm that I received your transmission'. Many ham operators worldwide often exchange post cards, as 'hard copy' proof of their meeting on the air. These cards are also referred to as 'QSL cards'.
When disaster strikes, terrestrial communications go down and cellular networks are immediately destroyed, there are a Corps, Ambulance, Red Cross, Hospitals of amateur radio …operators around the world ready to help. Amateur Radio technologies are constantly evolving, and have in its history found a high degree of importance in emergency communications. The technologies and operations procedures are highly developed and many operators have trained and participated in handling emergency communication traffic acting as a liaison between the public and official sources. Amateurs as individuals and groups both locally, nationally and worldwide have always put emergency communications at the forefront of the technological hobby. When emergencies start or disasters occur, the rag chewing (normal conversation) stops. All amateurs both by habit and regulation respect the importance of emergency communications and focus on the situation at hand. There is a true camaraderie that overrides any differences of opinion. Perhaps it's because Amateur Radio privileges are hard-earned and thus not given freely. In the days of internet, family radio and citizens band operators, many regard hams as a cut above the rest as civilian communicators.
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)
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.
ADVANTAGES Durring a hurricane, tornado, wildfire, ect when all other forms of communication are un-usable, you can still use ham radio to gain knowledge about where to find w…ater, ice, gas, shelter, ect. or to ask for help.If you want to talk to people you don't have to pay a minute-ly fee, all you have to do is buy a radio and talk all you like!You can talk to all sorts of people, the possibilities are endless. You can make friends, learn about all sorts of things you would never have known about otherwise.You can help your community recover from a disaster after you join an organization like ARES or RACES.You can learn all about radio and radio theory and learn Morse Code and practice it with other hams.You can participate in radio related contests like field day.You can do fun things like talk to the International Space Station or bounce your radio signal off the moon, a comet or even a meteor! DISADVANTAGES You wont be able to call a specific station unless you have already scheduled the meeting.Your radio might not be able to reach all over the world without a better antenna
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.
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.
Radios are radios . . . some are used by broadcasters, some are used by the military, some are used by ordinary people, and some are used by amateur radio operators (Hams). …Guglielmo Marconi invented the radio. (Goo-LYEL-moe marr-CONE-ee)
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.
The process is very complicated, but I can simplify it here. A signal starts as a wave in the oscillator of the radio. You speak into the microphone, and this produces another… wave at your voice frequency. These two signals go into the modulator, which uses the voice signal to encode the wave from the oscillator, or modulate it. This signal is sent out of the antenna. The receiver is like a transmitter in reverse (obviously), that decodes it, and sends the decoded signal into the speaker.
I am a ham radio operator. Radios can come in all different sizes. Some are as small or smaller then a deck of playing cards,(these are handheld radios), while others are …the big boxes classically thought of as ham radios. ==== I am too. A ham radio can fill a "relay rack" ... 19-in wide by 7-ft tall ... and I have even seen a radio transmitter used for 'hamming' that was 6-ft wide, built into the wall between two rooms, and from the room behind it, you could walk inside it to change the final power- amplifier tubes. Some people are really serious about their hobbies! On the other end of the spectrum ... on my high-school budget ... I once built a 'transceiver' ... a combination transmitter/receiver ... into a school lunch box, and completed a two-way 'contact' with it from upstate New York to Puerto Rico. I was overcome with joy, but my sister did not share my enthusiasm, as it was her lunch box.
Answer #1: Ham radio can help us in many ways. Mostly police and security organizations use this equipment to communicate with each other. It is also used in m…any buses, caps and trucks. They use it to communicate it with their main offices. Mostly constructors use ham radios with their co-workers to talk about their work. When the network is down of mobile phone then mostly people use ham radios. It is also used in disasters because of networks are mostly down at those areas. ===== Answer #2: -- Police and security organizations do not use ham radio equipment to communicate with each other. -- Ham radio may or may not be used by hams for recreation and personal hobby communications while they are passengers in buses, caps, and trucks, but it is not used by the drivers of any of them to communicate with their main offices. -- Ham radio is not used on construction sites, industrial sites, chemical plants, steel plants, or oil refineries for communications among co-workers. -- Ham radio is not used at all as a backup for the mobile phone network. -- Ham radio may or may not be active in a disaster area, when normal public communications with the outside are inadequate or have been cut. When it is, it's not used by any official law or rescue agency. It's always provided by private volunteers, most often using their own privately owned equipment. -- Ham radio is never used on a job or in a government operation. It's never used for pay, and is used only by people who have Amateur Radio ('ham') licenses..
