Chatham Heard Round the World

May 12 - December 31

Our newest exhibit, “Chatham Heard Round The World” opens in the Wireless History Gallery.

The public is invited to attend, and to stay to preview the museum’s exhibits updated for the 2018 season. Further details will be posted as they are known. Upon regaining the station after World War II, RCA built its most modern transmitting facility in nearby South Chatham to replace the aging transmitters that were forty miles west in Marion.

Paired with the receiving station in Chathamport, it made Chatham Radio (call sign WCC) the largest ship-to-shore station in the United States, renowned among mariners of all nations. The new “Chatham Heard Round The World” exhibit features one of South Chatham’s seventeen large RCA model SSB T-3 twenty kiloWatt transmitters, refurbished for demonstration. Visitors experience firsthand how a radio operator touching a Morse code key in Chatham could be heard by his counterparts aboard ships sailing the seven seas – long before satellites – and learn about the talented and skilled people who conceived, built and operated the transmitting facility.
