We delve into the Media Network archives to look back at the early days of commercial shortwave broadcasting from the United States. On October 15, 1927, Walter Lemmon, a radio inventor, was granted the first shortwave radio license in the United States and began experimental shortwave station W1XAL in Boston, Massachusetts. In 1935, the station began transmitting non-commercial, educational, and cultural programs. Supported by charitable institutions it was a not run for profit. The broadcasts came from a transmitter site in Scituate, Massachussets.
I found some recordings of the station in the audio section of the US Library of Congress for this programme. And Lou Josephs got me the recordings from a later stage in the station's history when it was WNYW, Radio New York World Wide. He used to work there as a Saturday job in the 1970's, and made some great studio recordings which I haven't heard elsewhere.
