Please look for your fellow contesters as PVRC activates the historic 
NSS call sign on Saturday, May 8, during the 2021 Armed Forces 
Day Cross-Band Test . For more than 60 years, military and amateur 
stations have taken part in this exercise, during which military stations 
transmit on military frequencies and listen for radio amateurs in 
adjacent amateur bands. 


NSS operation will be from the location of the former US Navy 
High Power Radio Station at Greenbury Point in Annapolis, Maryland. 
NSS began operation in 1918 on VLF, using a pair of Federal Telegraph 
Company 500 kW Poulson arc transmitters and four 600-foot towers. 


NSS began operations on HF in the 1920s, and operations there 
continued until 1976. NSS was dismantled in 1999, but three of its 
600-foot towers remain on Greenbury Point. A commemorative 
NSS QSL card is available via K3LU (SASE appreciated).
