Peter Dahl, K0BIT, of El Paso, Texas, passed away August 15 of Parkinson’s disease. He was 71. In 2007 after more than 40 years, he closed his company -- the Peter W. Dahl Company -- citing health reasons. “I want to thank everyone for their business throughout the years,” Dahl told the ARRL upon his retirement. “I have enjoyed making each Amateur Radio transformer.”

While still a student at the University of Minnesota, Dahl founded the Peter W. Dahl Company, manufacturers of a wide variety of custom transformers and reactors for Amateur Radio, as well as commercial radio and television applications. According to Dahl, many were direct replacements for original equipment components that were no longer available from the manufacturer, while others had general-purpose applications in any number of different transmitters. In 2007, he told the ARRL that his company had more than 4000 individual transformer designs on file. QST columnist John Dilks, K2TQN (“Vintage Radio”) remembered that the closing of the Dahl Company was “sad news for those of us who restore the big iron.” After retiring, Dahl sold his designs to Harbach Electronics.
