0051z and 0052z DANDY DAN with their daily communications test count. (see
1935z).
8992.0 was active at 0823z with EIGHT AMP (NCS HFGCS) broadcasting the
120-character EAM H5VSNM. It conforms to the structure of other 120
characters strings:
6 preamble/17 block/4 [18/quad] blocks/9 ending block.
Example below reformatted for clarity (if the gmail fixed-width formatting
holds):
H5VSNM
NP3CYDHZNLZUCG2S7
2VOBCYRKCPQ6NKCOZIKKKK
RX2O6DC6RR7243LT32HHHH
EGL7TR3CTDIHFFVOEOVVVV
ME44YDWYYFWOJJN6O62222
LCOZBON63
Why include the 18 characters before the KKKK quad? Note the placement and
spacing of the "C"s and compare with the placement and spacing of the
first and third "Y"s in the 2222 quad block. Coincidence? Probably/maybe
but it catches the eye and things such as that become noticeable over time
(decades). Sometimes it's there and sometimes not. And placements vary
string to string if they happen in this series of EAMs. There are other
placement coincidences in the above string's 18- character blocks as well
if you look. [Prior to April 2013 those were 19/quad and 10 character
ending blocks.]
