From the eam.watch website:
Emergency Action Messages (EAM's) are encrypted messages sent through the High Frequency Global Communications System (HFGCS).
While the messages can not be decrypted by the average person, the frequency of broadcasts, and types of broadcasts are interesting.
Due to the fact EAM's and SKY KING messages can be used to direct nuclear forces it has become a hobby for some to try and detect the on-set of WW3 by looking for abnormally large amount of traffic being broadcasted.
The goal of this site is to help detect patterns in broadcasts that can be associated with real world events, and operating procedures.
