In 1936 our family moved to a small town in northern Minnesota. I was 10 at the time. The son of the landlord who lived across the street had a radio repair service in their house. I would watch him work on radios and other home appliances. There were a lot of battery operated radios. A B and C batteries were needed to run one radio.
As years went by, I still had radio in my mind. When I entered the navy in WW2, I took a radio test and failed it. When I got out I took a correspondents course in radio. I got into Amateur Radio and have had the hobby since 1952. This has expanded into computers too.
