There is no Enigma ID for this transmission because it is not a numbers 
station.

This is an encoded transmission in the US military HF-GCS (High Frequency - 
Global Communications System, primarily an Air Force system but also used by 
other branches of the mil).  These transmissions happen regularly and range 
from just a few characters to over 250.  Although these are often called 
EAMs (Emergency Action Messages) there are many types of messages actually 
sent on these frequencies.

Primary frequencies used would be 4724, 6739, 8992, 11175, 13200, and 15016 
kHz, all in USB mode.  Other frequencies can be used.

You will likely notice an echo on the signal on any or all frequencies. 
This is mostly caused by multiple transmitters sending the same message, but 
network lag causing each to send at a slightly different time.  However, 
there is a bit of propagation delay to your location for each specific 
transmitter, so this is also influencing the echo affect.
