0413z  29 Jan 24

28 Jan 24 UTC:

     11175.0 was active at 0233z with SHALIMAR (believed to be PULL 68 E6B
ex TRAVIS) working as an IMPROPER (NCS HFGCS).

     0256z: IMPROPER broadcast the 30 character EAM FB7WCO.

     0317z 22.7 KHz VLF FSK became active with FB7WCO

     0320z PALM DATE (not using SHALIMAR; perhaps another instance of a
callword for launch; and, a callword for the traffic mission) broadcast
FB7WCO. H+20/h+50 TACAMO PAC restoral broadcast window. Repeated at 0350z;
0420z; 0450z and 0520z.  PALM DATE/PULL 68 not visible on ADSB mapping
sites. Flying dark.

     1151z PULL 68 becomes visible on ADSB mapping sites while on approach
to TRAVIS.

     11175.0 was active at 1423z with IMPROPER broadcasting the 30
character EAM FBPJK7.

     11175.0 was active at 1620z with LONE ACE broadcasting FBPJK7 at the
H+20/h+50 TACAMO PAC restoral broadcast window.  No E6B visible on
ADSB mapping sites prior or during LONE ACE's broadcasts.  Flying dark.

     11175.0 was active at 1907z with IMPROPER broadcasting the
30-character EAM FBQSAA.

     1920z: LONE ACE broadcast FBQSAA at TACAMO PAC's restoral windows.
1950z; 2020z; 2050z.  22.7 KHz VLF FSK broadcasts around 1950z+/-

29 Jan 24 UTC

     11175.0 was active at 0021z with FREELAND calling and eventually
raising GRASS FOX (NCS HFGCS) to exit the net (approx 0027z).

     11175.0 was active at 0250z with GRASS FOX broadcasting the
30-character EAM FBV5EU.

     8992.0 was active at 0311z with FREELAND calling and working GRASS FOX
to enter the net. California SDR but both appeared to be simulcasting on
11175.0,

     0320z: FREELAND broadcast FBV53U at the TACAMO PAC H+20/50 restoral
broadcast window.  Again at 0350z.

     As with earlier TACAMO PAC callwords, FREELAND was not visible on ADSB
mapping sites. Flying dark.

     For the past two UTC days Pacific trailing wire NOTAM reservations
have been for 24 hours windows.  Everyone is apparently flying due regard.

     The above took place with HFGCS NCS standing by for traffic activity
and numerous other EAM transmissions. Only the apparent E6 related activity
is logged above.
