A Hamfest is a convention of amateur radio enthusiasts, [1] often combining a trade show, flea market, and various other activities of interest to amateur radio operators (hams). [2] In the United Kingdom the term rally is more commonly used for amateur radio conventions. [3] "Hamfests" were noted as early as 1924 in the U.S. [4]

Hamfests are events organized by amateur radio enthusiasts, for social gatherings and promotion of amateur radio hobby. Typically annual or semiannual events are held over a weekend, they can last from several hours to several days. Most feature a flea market where the attendees buy and sell radio and related equipment. The equipment found at a hamfest can vary significantly from the newest high-tech gear to used, refurbished, or even antique equipment. Haggling or bargaining is the most common means of sale. Equipment that was originally sold at great expense to commercial users (such as public safety agencies) can often be found at a fraction of the price. Likewise, accessories which are no longer available from manufacturers may be found, and many sales of complete systems are made to buyers who only need one or two components. Junk boxes are common, frequently containing scraps and remnants from finished projects or equipment long-since gone. Some hamfests feature demonstration and sales booths staffed by vendors and manufacturers of commercial amateur radio equipment. Hamfests may also include meetings of amateur radio clubs, seminars on technical, operational, or legal aspects of amateur radio, and license examination sessions.
The Dayton, Ohio Hamvention, the International DX Convention, the HAM RADIO event in Friedrichshafen, Germany, and the Central Coast Amateur Radio Club Field Day near Sydney in Australia are events where manufacturers most commonly introduce new products to the amateur radio marketplace.
In the United States, hamfests are a popular tradition; regularly scheduled hamfests in the USA begin with an event such as a waffle breakfast, with proceeds going to the sponsoring organization or a worthy charity. Larger hamfests almost always include one or more food vendors, staffed by volunteers, with the proceeds going to a local high school or other charity.
It is not unknown for a seller to ask more for a single part from the box than for the entire box, the intent being to have less stuff when it's time to go home than the seller arrived with. Larger old items are often referred to as boat anchors with the suggestion that they are obsolete and of such low value that this is the only use left for them. Numerous jokes are based on this concept, and some sellers will tie ropes to handles, or post signs on especially large and heavy items seeking customers who own aircraft carriers. Regular attendees often visit their first hamfest in search of some piece of equipment, but end up returning due to the social aspect. [5]
In the current century, the Internet has come to be used to advertise and sell ham radio equipment, downgrading the sales of useful used equipment at all hamfests. This has, in many cases, caused the disappearance of many local and regional hamfests. Thus, hamfests' social aspects have become more of a reason to attend as well as to learn from the numerous lecturers and forums. Door prizes and raffles also occur. Also, inspection of the vast array of commercially made new radio equipment (conveniently available in one place) and the extensive inclusion of computers and computer parts and software for sale rise in importance at these events.
The Dayton Hamvention is generally considered to be the world's largest hamfest. [6] [7] It is held each May (formerly at the Hara Arena in Trotwood, Ohio near Dayton) at the Greene County Fairgrounds and Expo Center in Xenia, Ohio. The Hamvention offers forums, exhibit space and a flea market. Average attendance is around 25,000; there were 28,417 visitors in 2018. [8] Many amateur radio enthusiasts go out of their way to attend the Hamvention, travelling from all over the United States, Canada, Mexico and various parts of the world and even as far as Australia, Japan and Russia.
The second largest hamfest in the world is the Orlando HamCation in Orlando, Florida with over 23,000 visitors per year [9] [10] and 74 years running. Smaller regional hamfests include the 60 year young Shelby Hamfest in North Carolina, hosting 5,000 to 7,000 visitors per year, [11] Huntsville Hamfest in Alabama, Atlanta Hamfest celebrating 90 Years, and SEA-PAC in Seaside, Oregon. Hamfests can also be as small as a few hundred local attendees.
The largest hamfest in New England (and the Northeastern United States) is the New England Amateur Radio Festival, commonly known as NEAR-Fest, which is held twice a year, May and October, at the Deerfield Fairgrounds in Deerfield, New Hampshire. Deerfield is located approximately 15 miles (24 km) east of Manchester on Route 43. The DFW Ham Radio Expo is held every June in Lewisville, Texas.
Two of the largest Hamfests in Canada are HAM-EX, [12] held by the Peel Amateur Radio Club (PeelARC) and the Mississauga Amateur Radio Club (MARC), once a year at the Brampton Fall Fairgrounds just north of Brampton, Ontario, and the York Region Amateur Radio Club [13] (YRARC), on the first Saturday of November each year at the Newmarket Community Centre Newmarket, Ontario. Both of these Hamfests typically attract over a thousand visitors each year. Many smaller Hamfests are also held in every province across Canada each year. A full listing of Canadian Hamfests can be found on the Radio Amateurs of Canada (RAC) website. [14]
In Western Australia, the biggest Hamfest is run by the Northern Corridor Radio Group. They held their first few at the former Carine TAFE College site. Following its closure their hamfests have been held in Bassendean, a suburb of Perth. 2007 saw a demonstration of military radio equipment and a demonstration of a tesla coil. These were in addition to the "bring and buy" tables and stands for various retailers and groups. [15]
In the United Kingdom the two largest hamfests, referred to locally as Radio Rally's, are held by the Radio Society of Great Britain and National Hamfest Ltd. Many smaller Rally's are held by Radio Clubs up and down the country such as The Stockport Radio Society and the Lincoln Short Wave Club [16] among others. [17]
The International Exhibition for Radio Amateurs known as HAM RADIO in Friedrichshafen, Germany, is Europe's largest and most well-known hamfest (17,080 visitors in 2015), [18] which includes a trade show and "youth days". The first HAM RADIO took place in 1976 with 62 exhibitors. [19]
In India, Hamfest has been popular since 1991. In 2009, it was held in Bangalore, along with Golden Jubilee celebrations of Bangalore Amateur Radio Club VU2ARC [20] Two ham conventions, with mostly forums, were held by the National Institute of Amateur Radio in Hyderabad in recent years which uniquely coupled the events with major DXpeditions, allowing foreign hams to operate from the rare locales of Andaman I and Lakshadweep I.
Japan, the primary source for new commercially made ham equipment, hosts at least one large annual hamfest with world-wide attendees.
In amateur radio, QRP operation refers to transmitting at reduced power while attempting to maximize one's effective range. QRP operation is a specialized pursuit within the hobby that was first popularized in the early 1920s. QRP operators limit their transmitted RF output power to 5 W or less regardless of mode.
The American Radio Relay League (ARRL) is the largest membership association of amateur radio enthusiasts in the United States. ARRL is a non-profit organization, and was co-founded on April 6, 1914, by Hiram Percy Maxim and Clarence D. Tuska of Hartford, Connecticut. The ARRL represents the interests of amateur radio operators before federal regulatory bodies, provides technical advice and assistance to amateur radio enthusiasts, supports a number of educational programs and sponsors emergency communications service throughout the country. The ARRL has approximately 161,000 members. In addition to members in the US, the organization claims over 7,000 members in other countries. The ARRL publishes many books and a monthly membership journal called QST.
In the United States and Canada, the Amateur Radio Emergency Service (ARES) is a corps of trained amateur radio operator volunteers organized to assist in public service and emergency communications. It is organized and sponsored by the American Radio Relay League and the Radio Amateurs of Canada.
A DX-pedition is an expedition to what is considered an exotic place by amateur radio operators and DX listeners, typically because of its remoteness, access restrictions, or simply because there are very few radio amateurs active from that place. This could be an island, a country, or even a particular spot on a geographical grid. DX is a telegraphic shorthand for "distance" or "distant".
The 15-meter band is an amateur radio frequency band spanning the shortwave spectrum from 21 to 21.45 MHz. The band is suitable for amateur long-distance communications, and such use is permitted in nearly all countries.
Contesting is a competitive activity pursued by amateur radio operators. In a contest, an amateur radio station, which may be operated by an individual or a team, seeks to contact as many other amateur radio stations as possible in a given period of time and exchange information. Rules for each competition define the amateur radio bands, the mode of communication that may be used, and the kind of information that must be exchanged. The contacts made during the contest contribute to a score by which stations are ranked. Contest sponsors publish the results in magazines and on web sites.
In times of crisis and natural disasters, amateur radio is often used as a means of emergency communication when wireline, cell phones and other conventional means of communications fail.
Ham radio is a popular term for amateur radio, derived from "ham" as an informal name for an amateur radio operator. The use first appeared in the United States during the opening decade of the 20th century—for example, in 1909, Robert A. Morton reported overhearing an amateur radio transmission which included the comment: "Say, do you know the fellow who is putting up a new station out your way? I think he is a ham." However, the term did not gain widespread usage in the United States until around 1920, after which it slowly spread to other English-speaking countries.
Hara Arena was a 5,500-seat multi-purpose arena located in the Trotwood, Ohio suburb of Dayton. The facility began as a ballroom in 1957, added an arena in 1964 and grew to a six-building complex which closed in August 2016.
Vintage amateur radio is a subset of amateur radio hobby where enthusiasts collect, restore, preserve, build, and operate amateur radio equipment from bygone years, such as those using vacuum tube technology. Popular modes of operation include speaking over amplitude modulation (AM), and communicating using Morse code through continuous wave (CW) radiotelegraphy. Some enthusiasts have interest in owning, restoring and operating vintage military and commercial radio equipment such as those from 1940s to 1960s. Some undertake to construct their own gear, known in ham slang as homebrewing, using vintage parts and designs. A number of amateur radio clubs and organizations sponsor contests, events, and swap meets that cater to this specialized aspect of the hobby.
The Global Amateur Radio Emergency Communications Conference or GAREC was a conference held annually from 2005–2014 by the International Amateur Radio Union for discussion of amateur radio operation during natural disasters and other emergencies with the motto, "Saving lives through emergency communications". GAREC was first held in Tampere, Finland in 2005, coinciding with the adoption of the Tampere Convention, a globally binding emergency communications treaty that had been signed in Tampere in 1998. In later conferences, the venue has attempted to rotate in sequence through ITU Regions 1, 2 and 3.
Amateur radio or ham radio is practised by more than 22,000 licensed users in India. The first amateur radio operator was licensed in 1921, and by the mid-1930s, there were around 20 amateur radio operators in India. Amateur radio operators played an important part in the Indian independence movement with the establishment of illegal pro-independence radio stations in the 1940s. The three decades after India's independence saw only slow growth in the number of operators until the then Prime Minister of India and amateur radio operator, Rajiv Gandhi (VU2RG), waived the import duty on wireless equipment in 1984. Since then, numbers have picked up, and as of 2007, there were more than 16,000 operators in the country. Amateur radio operators have played a vital role during disasters and national emergencies such as earthquakes, tsunamis, cyclones, floods, and bomb blasts, by providing voluntary emergency communications in the affected areas.

The event is an excellent occasion for Hams and SWLs to meet each other and to keep updated on latest developments. It usually has technical sessions, presentations, exhibitions, demonstrations, sales of radio equipment and a flea market. The event also propose to create more awareness on Ham Radio. ‘Hamfest India' is precisely the largest gathering of Indian HAMs in one place.
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. The term "amateur" is used to specify "a duly authorized person interested in radioelectric practice with a purely personal aim and without pecuniary interest"; and to differentiate it from commercial broadcasting, public safety, or professional two-way radio services.
Ham Radio (HR) was a monthly amateur radio enthusiast magazine published in the United States from November 1967 to June 1990.

Although there is anecdotal evidence of an amateur radio club in Omaha prior to World War II, The Ak-Sar-Ben Amateur Radio Club (AARC), as it exists today, was started in 1945 and has been affiliated with the American Radio Relay League (ARRL) since that time. The club is not affiliated with The Knights of Ak-Sar-Ben.
OSCAR 1 is the first amateur radio satellite launched by Project OSCAR into low Earth orbit. OSCAR I was launched December 12, 1961, by a Thor-DM21 Agena B launcher from Vandenberg Air Force Base, Lompoc, California. The satellite, a rectangular box weighing 10 kg., was launched as a secondary payload (ballast) for Corona 9029, also known as Discoverer 36, the eighth and final launch of a KH-3 satellite.
The Yaesu FT-891 is a HF and 6 meters all mode mobile amateur radio transceiver. The FT-891 was first announced to the public by Yaesu at the 2016 Dayton Hamvention. The radio has 100 watts output on CW, SSB, and FM modulations and 25 watts of output in AM. As a mobile transceiver the FT-891 is well suited for mobile installation in vehicles, and weighing less than 5 pounds it is often used for field activations such as Summits On The Air and Parks On The Air. The radio has been praised for its noise reduction and sensitive receiver. Common criticisms of the radio include its many menus that are difficult to navigate with its small screen, the lack of VHF/UHF capabilities, and lack of an internal antenna tuner. Although the radio lacks an internal sound card it still has input and output jacks for audio and be controlled over a USB cable allowing the radio to use digital modes such as WinLink, PSK31 and FT8.
