The radio's theory of operation is based on the principle of the Wadley Loop and was one of the first radios marketed by Tandy Corporation to have a digital frequency display. The DX-300 was succeeded by the improved DX-302 in 1980. Picture of the front of a Realistic DX 300 HF receiver in operation
RadioShack (formerly written as Radio Shack) is an American electronics retailer that was established in 1921 as an amateur radio mail-order business. Its original parent company, Radio Shack Corporation, was purchased by Tandy Corporation in 1962, shifting its focus from radio equipment to hobbyist electronic components sold in retail stores.
The TRS-80 series of computers were sold via Radio Shack & Tandy dealers in North America and Europe in the early 1980s. Much software was developed for these computers, particularly the relatively successful Color Computer I, II & III models, which were designed for both home office and entertainment (gaming) uses.
The Tandy 2000 is a personal computer introduced by Radio Shack in September 1983 based on the 8 MHz Intel 80186 microprocessor running MS-DOS. [2] By comparison, the IBM PC XT (introduced in March 1983) used the older 4.77 MHz Intel 8088 processor, and the IBM PC/AT (introduced in 1984) would later use the newer 6 MHz Intel 80286.
By then computers were 35% of Radio Shack sales; the Model 100 was the world's best-selling notebook computer, while Tandy was the leading Unix vendor by volume, selling almost 40,000 units of the 68000-based, multiuser Tandy Model 16 with Xenix, [17] [23] and began selling all computers using the Tandy brand [24] because, an executive admitted ...
The radio's theory of operation is based on the principle of the Wadley Loop tuner [1] (developed by Trevor Wadley in the 1960s), and was one of the first radios marketed by Tandy Corporation to have a digital frequency display. The DX-302 succeeded and improved upon the similar Realistic DX-300. The frequency range is from 10 kHz to 30 MHz. [2]
Frequency counters designed for radio frequencies (RF) are also common and operate on the same principles as lower frequency counters. Often, they have more range before they overflow. For very high frequencies, many designs use a high-speed prescaler to bring the signal frequency down to a point where normal digital circuitry can operate. The ...
With fewer than 100 stores, far fewer than the aggressively expanding Radio Shack's thousands of local outlets, Lafayette Radio remained more of a dedicated enthusiasts' store than a mass marketer. The company was also hurt by the advent of electronics retailers relying on aggressive marketing techniques and competitive pricing in the late 1970s.
