    Historic NSS Call Sign - Reactivated - 100th Anniversary

    Historic NSS Call Sign to be Reactivated During its 100th Anniversary

    Historic U.S. Navy callsign NSS will be reactivated during the 100th anniversary of the former Naval Radio Station in Annapolis, Maryland.
    The U.S. Naval Academy Radio Club (W3ADO) and the Potomac Valley Radio Club (W3GRF) will reactivate the historic callsign during the upcoming Armed Forces Day Crossband Military/Amateur Radio Communications Test.

    NSS operations from the location of the former Naval Radio Station on Greenbury Point will be from 1300Z Saturday May 12 to 0200Z May 13.
    CW and SSB transmissions will be on 4038.5, 5330.5, 7533.5, 9447, 14487 and 17545 kHz. NSS will listen for callers on announced frequencies in adjacent amateur bands. Commemorative QSLs will be sent for all QSOs.

    NSS began operations in 1918 as the Annapolis High Power Radio Station using a pair of Federal Telegraph Company 500 kilowatt Poulson Arc transmitters and four 600 foot towers operating in the Very Low Frequency (VLF) band. At that time VLF provided the only known capability for trans-oceanic radio communications. NSS began continuous operations in the HF bands about ten years later until 1976 when its HF mission was transferred to Naval Radio Station NAM in Norfolk, Virginia. The 1200 foot central tower and dozens of other towers and masts were demolished in 1999, except for three iconic 600 foot Eiffel towers that remain at the southern tip of Greenbury Point.

    As naval aviation was under development, so was another pivotal early 20th century invention, the radio. The Navy was a very early adopter of wireless communication, and the outbreak of World War I necessitated an alternative to the transatlantic telegraph. The massive radio complex at Greenbury Point across the river from the Naval Academy filled this need. The three towers remaining today help us discuss the birth of radio, and the incredibly rapid evolution of wireless communications in the Navy.
