[Jeff Haverlah]

2021z 20 Dec 24

     1532z+/- SUTRA 96 E6B launches from TINKER.

     1536z 11175.0 USB; NEW MOON (SUTRA 96) called and raised ABSENTLY (NCS
HFGCS) and entered the net.

     NEW MOON flew to the Gulf of Mexico.

     1743z 11175.0; ABSENTLY broadcast the 30 character EAM "NDTD3S."

     As seen above, the NCS sent one version of NDTD3S; and, the TACAMO
sent a different version of NDTD3S via voice and VLF FSK.

     The 1830z broadcast slot was noticeably unfilled. The NEW MOON 1857z
broadcast of the version 1 string was equivalent to NEW MOON's initial
version 2 broadcast at 1747z, immediately followed by the 1900z restoral of
the version 1 string.

     SUTRA 96 is now returning to the Texas shore.

     There was no variance in mission callword this flight (most common
situation.)

     Where did that version 2 6-character block come from?
