• Anotaciones
• In 1922, "Hallock and Watson" started to manufacture their first radio models RF12 and RF22. This was still as "Hallock and Watson Radio Service" at 192 Park Street - mentioning "KGG". In 1923 the company became the name "Hallock & Watson Radio Corp.". They continued with those models. ARC June 2006: "The manufacturing plant was located at 406 East Alder Street across the river from downtown. The firm soon produced two superhet receivers -- a Porta-pak 8 model containing a 5-volt panel meter, of which 577 were manufactured, and the 8-tube set, shown in Figures 4 and 5 (see print version). Manufacturing superhets made Hallock and Watson subject to future litigation from RCA. In fact, attorneys from RCA visited Hallock at his Portland plant and strongly suggested that if he did not stop making superheterodynes, the firm of Hallock and Watson would face a lawsuit for patent infringement.
  
  The company appears to have made a wise decision and switched to manufacturing TRF sets. The two Type TR-5s, made in 1925 and 1926, were the first models to bear the "Halowat" label. A distinctive logo was designed displaying three small lightning bolts at each end of the Halowat name. The Model TR-5 sold for $90 and incorporated the tuned radio frequency circuit. Views of the TR-5 are shown in Figures 6 through 9 (see print version)."
