Collins, Art, 9CXX/WØCXX. Founder, Collins Radio Co.; set the standard for amateur radio equipment in the 1950s, ’60s, and ’70s.
Seventy-five years ago a small radio communications company, operating from the owner's basement, officially incorporated in the state of Delaware. From these humble beginnings arose one of the nation's foremost communications and avionics companies -- The Collins Radio Company. Arthur Collins, W0CXX, started building high quality Amateur Radio equipment that from the very beginning was to make the Collins brand legendary among ham radio operators worldwide. The Collins Radio Company was incorporated with $29,000 in capital and eight employees during the depth of the Great Depression. In 1973, Collins was acquired by Rockwell International. In 2001 the company was spun off into what is today Rockwell Collins, Inc with over 19,500 employees worldwide and annual sales of $4.415 billion.
Fifty years ago, and 25 years after incorporation, in September 1958 Collins Radio introduced a completely new line of amateur communications equipment -- the S/Line. The 75S-1 receiver, 32S-1 transmitter and 30S-1 power amplifier set a new standard of excellence in areas of styling, reliability, frequency accuracy, stability, signal quality and linear amplification. The S/Line enjoyed a long production history and today still commands premium prices among classic radio enthusiasts and collectors.

Arthur Andrews Collins (September 9, 1909 – February 25, 1987) was a radio engineer and entrepreneur. He first gained national recognition as a teenager for significant advances in radio communication. He later founded his own radio engineering and manufacturing company in 1933, Collins Radio Co. Rapidly expanding during World War II, Collins Radio eventually grew into a Fortune 500 leader in avionics, telecommunication, and military, space and commercial radio communications. Collins and his company ultimately became pioneers in melding computer and communication technology. Widely considered a genius in electronics innovation, he shunned personal publicity and is relatively little known today, even within the electronics community.
Arthur A. Collins was born in Kingfisher, Oklahoma to Merle H. Collins (a mortgage banker) and Faith Andrews Collins (a graduate of Rockford College in Illinois). The family moved to Cedar Rapids, Iowa when Arthur was 7. Merle founded Collins Farms Company in 1925,[1] which combined inefficient small farms into one collective enterprise, using the best available equipment and modern practices (contour plowing and erosion control, crop rotation, newly available hybrid seed corn) to achieve greatly increased productivity. This novel approach was initially successful but faltered as the Great Depression hit. His son Arthur was intensely interested in radio, became a licensed amateur radio operator at age 14, and designed and built his own equipment, purchasing expensive vacuum tubes with his father's help. Arthur Collins became an expert in circuit design and wave propagation, publishing several articles in specialty journals.
Collins became friends with fellow amateur radio "hams", including John Reinartz, who shared a special interest in radio wave propagation. Within the radio spectrum only longer waves were thought to be refracted by the atmosphere ("skip"), allowing long-distance communication at night, but not so the shorter wavelength relegated to amateurs. Reinartz and Collins discovered that such "skip" did occur in the 20-meter range and during the daytime, which allowed long-distance communication with this type of equipment. When Reinartz became the ship's radio operator on the National Geographic-sponsored MacMillan Arctic expedition in 1925 only he and Collins were able to maintain reliable communication, unlike the U.S. Navy using longer wavelengths. Collins gained national recognition.[2][3][4][5]
Founding of Collins Radio[edit]
Collins founded Collins Radio Co. in 1933, building high quality amateur and commercial transmitters (not receivers for the domestic market). With recognition from success with the MacMillan expedition, Collins equipment was selected for the Byrd Expedition to the Antarctic (1933–1934).[6] Beginning manufacturing in his basement, Arthur Collins soon rented building space and eventually constructed the first Collins Radio factory in Cedar Rapids in 1940. At this time the company had sales of about $500,000 and 150 employees. Collins Radio was recognized for excellence in design and manufacture of amateur and commercial transmitters and receivers, and began building aircraft radios in 1935.[7]
Goddard, RCA, and the Collins vacuum tube patent suit[edit]
The heart of a radio transmitter, the oscillator, at that time used a vacuum tube to generate a radio frequency. RCA claimed it had exclusive rights to the de Forest vacuum tube oscillator circuit patent, and brought suit against Collins Radio and other purported infringers. In addition to rockets, Robert Goddard was also an electronics innovator, and when Arthur Collins discovered that Goddard's 1915 oscillator patent predated the de Forest patent Collins met with Goddard to explain that RCA's tube monopoly was a serious impediment to competitive innovation in electronics. With Goddard's help, the practicality of the Goddard design was demonstrated in court and the suit was dropped in 1938, allowing Collins and others to freely develop new technology. Goddard and Collins remained friends until Goddard's death in 1945.[8][9]
SSB and Amateur Radio[edit]
Amateur radio was never a dominant segment within the Collins Radio product line, but held a special interest for Arthur Collins since childhood and provided a key catalyst in the design of other equipment. Collin's amateur gear was always built to the highest standards and demanded a premium price. As part of KINEPLEX Collins developed the mechanical filter, a small device (about ¾ inch by 4 inches) using a series of precisely ground metallic discs linked mechanically and electrically. Determining the exact dimensions of these discs was critically important, and not easily discovered through empirical experimentation. A bright, young Indian mathematician named Roshan Sharma was fortuitously hired, based partly on his recent mastery of the necessary underlying mathematics needed to produce the resonating discs.
An input signal causes the first disc to mechanically resonate at a very precise and stable frequency, which passes an induced electrical oscillation to the next disc and in turn sequentially through the device. By filtering out unnecessary portions of the radio signal, the mechanical filter (a kind of "bandpass filter") allows the use of a very stable, precise single sideband frequency. (Previously, single sideband operation required a large, complex piece of equipment.) The mechanical filter was the heart of Collins single sideband (SSB) technology and made SSB practical for the first time. SSB offered clear, efficient radio communications, even during conditions that would disrupt and distort conventional radio signals.
In 1956 a SAC C-97 transport was fitted with Collins 75A-4 / KWM-1 SSB amateur gear for a demonstration of the superiority of SSB, leading to contracts for Collins SSB military equipment on B-52 and other aircraft, as well as ground stations. Sales far exceeded that of amateur sets. [19][20]
