A Competition and Ham Radio Award to the 90th Anniversary of first Amateur Radio licenses  in Czechoslovakia

First ilegal experiments with Ham Radio transmissions in Czechoslovakia were made by technical enthusiasts since early twenties of 20th Century. First license rules were made and accepted by the authorities in the second half of twenties.
Regardless of this fact there were no oficially licensed Amateur Radio Stations in Czechoslovakia until the half of 1930 year. On May, 19. 1930 the first exams of Ham Radio license applicants were made.
