Alexanderson alternator
In 1948, the WCC marine radio transmitter equipment was moved from Marion Station to RCA's newly built oceanfront transmitter station on Forest Beach Road in South Chatham, Massachusetts. The U.S. Air Force continued to use the Alexanderson alternator at Marion Station for weather and other broadcasts to its air base in Thule, Greenland and other arctic locations through 1957 under the callsign AFA2.
