Today the US Naval Academy Amateur Radio Club (W3ADO) activated the historic NSS callsign for Armed Forces Day — transmitting from the grounds of the former US Navy radio transmitting facility in Annapolis, MD.
This annual DoD crossband test has been running for over 50 years. Military stations transmit on military frequencies while monitoring amateur HF bands. If you made contact or just listened in, QSL cards are available through www.usarmymars.org. Full details at arrl.org.
