Monday, September 22, 1947 was a regular working day: schoolchildren hurried to classes, collective farmers harvested a crop that was not very plentiful that year, workers worked at machine tools, exceeding the daily norm; women and old people crowded at grocery stores, patiently waiting for the opportunity to buy food cards. The country lived hard, hungry, healing the wounds inflicted by the war. On that day, an event took place that had a great impact on the development of radio electronics and amateur radio in our country.
