Arthur Collins founded Collins Radio Company in 1933 in Cedar Rapid, Iowa, for the purpose of designing and producing both shortwave radio equipment and equipment for the burgeoning AM Broadcast industry. As the Collins reputation for fine quality and uncompromising construction grew, Collins was solicited by the military, the scientific community and by the larger AM radio stations for special equipment. The company captured worldwide attention when Collins supplied the equipment to establish a communications link with the South Pole expedition of Rear Admiral Richard Byrd in 1933.
Financial income increased steadily enabling Arthur Collins to continually change and enhance, broaden and diversify his equipment, which, in the end, became a dominant force in the radio equipment industry. By 1936 Collins had already begun production of their famous 12H audio console, 12X portable field announcers box and their 300E and 300F broadcast transmitters. The 300F design remained stable for over a decade with most remaining in service throughout the 1960s. They were replaced not because of equipment failure but because of relaxed rules permitting daytime only stations operating on clear channel frequencies to increase power and operate at night with 1000 Watts power and more. Throughout WW2, speech equipment also evolved dynamically as industry feedback influenced the designs at Collins. The 12H was quickly replaced with the stunning success of the 212A1 and 212B1 designs that remained in service for decades. It is important to note that during these initial decades of the Collins production of radio equipment, reliability and dependability characterized the demand for equipment. As an example, during the pre-WW2 years, the National Radio Company was the principal contractor for the US military. This changed with the US entrance into WW2 and Collins quickly became the principal supplier of radio and navigation equipment used in the military theater, where uncompromising performance was required.
