NSS Annapolis QSLs for SWLs

Front of the NSS QSL card–the back has contact info an excellent explanation of NSS with photos.

Many thanks to SWLing Post contributor, Ulis Fleming (K3LU), who writes:

I wanted to pass along some information regarding the NSS Annapolis radio station.

Last year’s cards were sent out for Armed Forces day with one generic card with all the callsigns. This year the ops at NSS will be sending cards direct on their own to ALL amateur stations who worked NSS without solicitation via their address posted in QRZ.com.

SWLs can send a full SWL report with station worked, time to K3LU via the QRZ.com address or email me for my address at K3LU@hotmail.com. A SASE is helpful but not necessary.

Thanks so much, Ulis! What a great service to the SWL community!

This weekend: Historic NSS Call Sign reactivated during Armed Forces Day Crossband Test

100th Anniversary QSL card for NSS

Many thanks to SWLing Post contributor, Brian Smith (W9IND), who shares the following press release regarding the historic U.S. Navy callsign NSS that will be reactivated during the 100th anniversary of the former Naval Radio Station in Annapolis, Maryland:

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.
