A Landmark Date In Radio History

Following World War I, the newly-formed Radio Corporation of America (RCA) acquired the assets of the Marconi Wireless Telegraph Company of America, including its unfinished installations at Chatham and Marion, Massachusetts.  RCA installed state-of-the-art equipment manufactured by U.S. industrial giant General Electric, and trans-Atlantic station WSO went on the air on May 17, 1920.  Come explore our newest exhibit, “Chatham On The Air”.


Chatham Marconi Maritime Center introduces “Radio to the Rescue”. 


 At the turn of the 20th century, radio communication ended the isolation of mariners at sea.  Valuable lessons learned from early sea disasters on up to the present day help keep people safe today and have saved countless lives.

Enjoy a series of special events, fascinating speakers and new exhibits at the Marconi-RCA Wireless Museum.
