MALT 31 (E6B) launched from TINKER at 1423z 07 Mar 25 and flew to the Gulf.

     11175.0 was active at 1645z with RAINDROP (NCS HFGCS) broadcasting the
30 character EAM HJJGKX.

     11175.0 was active at 1700z, 1730z, 1800z and 1830z with PETTIBONE
(MALT 31) broadcasting HJJGKX at the NCS/ABNCP/Gulf h+00/h+30 restoral
rebroadcast windows.

     11175,.0 was active at 1840z and 1844z with PETTIBONE calling OVERRIDE
with no known response.  At 1848z PETTIBONE called ACQUAINT.  At 1849z
ACQUAINT responds and works PETTIBONE with a connectivity check (an
exchange of signal checks).  PETTIBONE then called ACQUAINT and went into
his 274 message traffic script: "VFZ YMA ABK; Time 50; Authentication QB; I
say again"; repeat of the three groups; and out. At 1850z ACQUAINT stated
"Copies all" and was quiet.

JIGGS 38 (E6B) launched from TINKER at 1856z+/- and flew to the Atlantic
off the Northeast coast.

     11175.0 was active at 1900z WHIPSAW (JIGGS 38) calling OVERRIDE with
no known response.  At 1901z WHIPSAW called OVERRIDE "for contact; how copy
my station; over" with no known response. At 1903z WHIPSAW called ACQUAINT
and eventually raised.  ACQUAINT requested that WHIPSAW spell his callsign.
WHIPSAW did not spell his callsign but eventually (1906z) ACQUAINT called,
raised, and worked WHIPSAW. Both exchanged signal reports, and WHIPSAW
terminated the call with no further traffic.

     11175.0 WHIPSAW called and raised RAINDROP at 1908z to enter the net.
During the challenge process RAINDROP keyed the system for a 30 character
EAM HF2GXV "FOR ZILCH." At the end of the EAM, RAINDROP immediately
concluded the challenge process with WHIPSAW.

     11175.0 was active at 1922z with WHIPSAW calling OVERRIDE and
immediately into his 274 three group traffic: "HZH VBN ABK; I authenticate
in the blind with Time 1922 and YJ; I say again"; repeats the entire
statement; and out.

     11175.0 was active at 2144z with PETTIBONE calling RAINDROP but
RAINDROP broadcast the 30 character EAM HJNAMF (see DISGUISE below). After
the EAM at 2150z PETTIBONE exits the net through RAINDROP.

     17.8 KHz VLF FSK (Atlantic) was active at 2202z with HJNAMF.

     11175.0 was active at 2210z, 2240z, 2310z and 2340z with DISGUISE
(JIGGS 38) broadcasting HJNAMF at the TACAMO LANT's h+10/h+40 restoral
rebroadcast windows.

 E4B ADFEB5 (GORDO 16) approached LAKE SUPERIOR at 2245z for some
pattern/orbital VLF work.

     31.7 KHz VLF FSK was active at 2316z with a CHANNEL
ONE/888800072315AAEEGGKKNNXXZZ8888 broadcast. The broadcast was repeated at
2329z.
