2012 Armed Forces Day Crossband Communications Test
 

The Armed Forces Day Crossband Military/Amateur Radio Communications Test (12 May 2012) is an annual opportunity for amateur radio operators and Military Affiliate Radio Service (MARS) stations to communicate by transmitting on frequencies in their respective services and listening to the frequencies used by the other service. The 2012 event will have MARS stations from the US Army, Navy, Air Force, Marine Corps and Coast Guard participating. Among these stations are several former US Navy vessels including the following:

NNN0CQQ Ex-USS Midway Museum Ship MARS Station (San Diego, CA)
NWKJ USS Yorktown (CV-10) (Patriots Point, Charleston, SC)
NWVC USS LST 325 (Evansville, IN)

More information including frequencies to be used can be found here:

US Coast Guard Station NMN CAMSLANT will also be participating according to this announcement:

Some of these stations may be using CW (Morse Code) as the transmission mode. I actually worked NWVC on CW last year during this event.
