The Genesis of Station J
Imagine the Florida coast in the early 1940s. The serene beauty of the Jupiter Inlet masked the dangers lurking offshore. German U-boats prowled these waters, turning them into treacherous hunting grounds for Allied ships. The need for decisive action was palpable, and thus, Station J was born.
Station J wasn’t just any military installation. Officially known as U.S. Naval Supplementary Radio Station Jupiter, this covert operation was designed to counter the U-boat threat. Utilizing high-frequency direction-finding technology, or “Huff Duff,” Station J intercepted and triangulated enemy transmissions. This intelligence was a game-changer, enabling Allied forces to strike U-boats with precision, disrupting their dominance in the Atlantic.
The Importance of Station J
Station J was a secret operation that intercepted U-boat radio messages and tipped off U.S. forces to attack enemy vessels. With radio receivers tuned to the frequencies used by the U-boats, Station J was able to pinpoint the names and locations of the submarines. Despite its small size, Station J played a crucial role in the war effort.
The building was constructed in 1939 and was used throughout the war. The Married Men’s Quarters housed senior radiomen and their families, providing a semblance of normalcy amidst the chaos of war. Each of the six apartments featured two bedrooms, a kitchen, a living room with a fireplace, and access to a screened porch facing the Loxahatchee River.

The Evolution of Station J: A Legacy of Transformation and Resilience
The story of Station J is one of transformation and resilience, marked by its evolving role through various hands and purposes over the years. As World War II drew to a close, the U.S. Navy transferred Station J to the Coast Guard on July 15, 1945. This shift marked a new chapter for the facility, which was repurposed to assist in locating distress signals and aiding rescue operations. The Married Men’s Quarters continued to serve as family housing during this period, maintaining its role as a supportive home base for military families.
In the early 1950s, the U.S. Air Force took over the building, incorporating the former Station J into the Jupiter Auxiliary Air Force Base. This base played a critical role in tracking missile tests from Cape Canaveral, with most of the equipment located on the north side of the lighthouse reservation. During this time, the building served a mix of purposes, including family housing, bachelor barracks, and classroom space. The Air Force contracted range operations to PanAm in 1954, continuing the use of the former radio station buildings until at least 1958.

From Military Quarters to Community Center
During the 1960s, the Coast Guard considered demolishing the Married Men’s Quarters to make way for new single-family housing along the riverfront. However, local leaders like Jupiter Mayor Robert F. Culpepper and Mayor Robert J. Nichols lobbied to save the building, recognizing its historical significance. Their efforts led to the creation of Lighthouse Park in 1968, with the building preserved and repurposed for community use.
By 1969, various civic groups had begun using the building. The east wing served as the offices and dispatch center for the North County First Aid Squad, which moved out in 1973. The wing then housed a senior club before becoming the Lighthouse Visitor Center in 1994 under the Loxahatchee River Historical Society’s management. The west wing hosted local organizations like the Jaycees and later served as a karate dojo, where Sensei Chuck taught classes by donation.
