This would tend to reinforce the argument made by a writer to Bill Gertz's column, who was quoted in the same post, that long EAMs generated by periodic exercises "should not be considered unusual."
Long EAM Examples:
Jeff Haverlah, a long-time Utility Logs contributor and generally Mr. EAM in this hobby, reported the following on February 17, 2007:
1729z 17 Feb 07
11175.0 was active at 1431z with OFFUTT bcsting a 248-character
EAM (TOXRB7) containing common, repetitive, distinctive formatting,
including the 14-character ending block common to these strings.
11175.0 was active at 1717z with OFFUTT bcsting a 163-character
EAM (TO57UN) containing distinctive (but not apparently repeating)
formatting including the 14-character ending block common to these
(Emphasis mine, for readability.)
Also from Jeff, this report of March 10:
0039z 11 Mar 07
11175.0 was active at 101722z+/- with OFFUTT (weak with deep
fading) bcsting a 201-character EAM (TOCDIJ) containing distinctive formatting and ending in a common 14-character ending block.
And, on 26 May, again from Jeff:
1555z 26 May 07
11175.0 was active at 1447z with ANDREWS (good levels here)
bcsting a 202-character EAM (IV3PR6) containing distinctive repetitive formatting (but did not end in the 14-character ending block common to these strings.) Activity common to utc Saturday's (1447z 28 Apr 07 245-character IVLZ7S) for example.) All Andrews xmsns are keying off with a soft pop/thump.
And, on June 23 near the beginning of the June 25 period in question, from Jeff:
1434z 23 Jun 07
8992.0 was active at 1418z with ANDREWS (good/fair levels here)
bcsting a 121-character EAM (IVSAD2) containing distinctive, repetitive formatting.
It seems significant that all of these long messages appeared at roughly one-month intervals, and on UTC Saturdays. There is a suggestion here of a monthly activity (likely a communications exercise) that generates long EAMs. We can therefore conclude that, while the June 25 activity was noteworthy for call signs, traffic volume, and a special test string, it was very much not noteworthy for EAM length. The writer to the Inside the Ring column appears correct.
