He was responsible for one of the country's first post-war radio broadcasts, when, on the evening of October 17, 1919, he entertained local amateurs with selections from phonograph records. This was the start of a series of test broadcasts, and the novelty of the entertainment proved popular with his audience. Responding to their interest, Conrad adopted a semi-regular schedule, primarily consisting of two hours on Saturday and also Wednesday nights. (The broadcasts weren't universally appreciated, as his wife later reported that he also "used to get phone calls at all hours of the day and night telling him to get off the air".)
