[MilCom] 7501.0 - EAM iterations

[Jeff Haverlah]

2207z  27 Oct 09

     7501.0 was active at 2201z with 0?Q (male opr; weak/mostly
readable) bcsting at least 3 EAMS:

I3EAKU (28 characters; I must of missed this on the HFGCS.)
RCPGWF (unknown character count because of weak signal but may have been 14)
I3FHKI (28-characters first heard at 1812z on HFGCS.)

Re RCPGWF:

This string conforms to past USN trigraph EAM activity where strings
heard earlier are sometimes subtly (or not so subtly) changed over the
course of the exercise.  Sometimes the changes are just a few letters
in the string, or a subtle shift in the preamble's characters.  In
this case the entire preamble is missing.

RCPGWF... is the 20-character EAM F4FLTR first heard on the HFGCS at
1803z minus the F4... 6-character preamble. (F4FLTRRCPGWF...)
