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 Q-code is a standardised collection of three-letter codes that each start with the letter "Q". It is an operating signal initially developed for commercial radiotelegraph communication and later adopted by other radio services, especially amateur radio. To distinguish the use of a Q-code transmitted as a question from the same Q-code transmitted as a statement, operators either prefixed it with the military network question marker "INT" or suffixed it with the standard Morse question mark UD.
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.
Popular Electronics was an American magazine published by John August Media, LLC, and hosted at TechnicaCuriosa.com. The magazine was started by Ziff-Davis Publishing Company in October 1954 for electronics hobbyists and experimenters. It soon became the "World's Largest-Selling Electronics Magazine". In April 1957, Ziff-Davis reported an average net paid circulation of 240,151 copies. Popular Electronics was published until October 1982 when, in November 1982, Ziff-Davis launched a successor magazine, Computers & Electronics. During its last year of publication by Ziff-Davis, Popular Electronics reported an average monthly circulation of 409,344 copies. The title was sold to Gernsback Publications, and their Hands-On Electronics magazine was renamed to Popular Electronics in February 1989, and published until December 1999. The Popular Electronics trademark was then acquired by John August Media, who revived the magazine, the digital edition of which is hosted at TechnicaCuriosa.com, along with sister titles, Mechanix Illustrated and Popular Astronomy.
Glenn Hauser is an internationally known American DXer and radio host from Enid, Oklahoma. He produces and presents a weekly 30-minute program, World Of Radio, heard on a number of non-commercial AM and FM stations throughout the U.S. and worldwide on shortwave.
DXing, taken from DX, the telegraphic shorthand for "distance" or "distant", is the hobby of receiving and identifying distant radio or television signals, or making two-way radio contact with distant stations in amateur radio, citizens band radio or other two-way radio communications. Many DXers also attempt to obtain written verifications of reception or contact, sometimes referred to as "QSLs" or "veries".
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.
QST is a magazine for amateur radio enthusiasts, published by the American Radio Relay League (ARRL). It is a membership journal that is included with membership in the ARRL. The publisher claims that circulation of QST in the United States is higher than all other amateur radio-related publications in the United States combined. Although an exact number for circulation is not published by the American Radio Relay League, the organization claimed 158,238 members at the end of 2021, almost all of whom receive the magazine monthly, in addition to issues delivered to libraries and newsstands.
ANALOG Computing was an American computer magazine devoted to the Atari 8-bit family of home computers. It was published from 1981 until 1989. In addition to reviews and tutorials, ANALOG printed multiple programs in each issue for users to type in. Almost every issue included a machine language video game—as opposed to Atari BASIC—which were uncommon in competing magazines. Such games were accompanied by the assembly language source code. ANALOG also sold commercial games, two books of type-in software, and access to a custom bulletin-board system. After the Atari ST was released, coverage of the new systems moved to an ST-Log section of the magazine before spinning off into a separate publication under the ST-Log name.
The AMPRNet or Network 44 is used in amateur radio for packet radio and digital communications between computer networks managed by amateur radio operators. Like other amateur radio frequency allocations, an IP range of 44.0.0.0/8 was provided in 1981 for Amateur Radio Digital Communications and self-administered by radio amateurs. In 2001, undocumented and dual-use of 44.0.0.0/8 as a network telescope began, recording the spread of the Code Red II worm in July 2001. In mid-2019, part of IPv4 range was sold off for conventional use, due to IPv4 address exhaustion.
W1AW is both the amateur radio call sign and the primary operating station of the American Radio Relay League (ARRL). This station, which is commonly called the Hiram Percy Maxim Memorial Station, is located on the grounds of ARRL Headquarters in Newington, Connecticut. It was inspired by Maxim's 1AW callsign which predated the use of the AA-AL, K, N and W prefixes. The station routinely transmits bulletins and Morse code practice using common amateur radio frequencies. During a communications emergency bulletins are transmitted hourly in order to keep amateur radio operators informed.
Electronics Illustrated was an American magazine started in May 1958 by Fawcett Publications, the publishers of Mechanix Illustrated.

It was one of the three influential computer magazines of the 1970s, along with BYTE and Creative Computing. It focused mostly on the kit-build market, rather than the pre-assembled home computers that emerged, and as the kit market declined in the early 1980s, Kilobaud lost relevance and closed in 1983. After this, company continued publishing other magazines dedicated to particular platforms rather than the kit market.
Homebrew is an amateur radio slang term for home-built, noncommercial radio equipment. Design and construction of equipment from first principles is valued by amateur radio hobbyists, known as "hams", for educational value, and to allow experimentation and development of techniques or levels of performance not readily available as commercial products. Some items can be home-brewed at similar or lower cost than purchased equivalents.
