0517z 11 Apr 25

     11175.0 was active at 0151z with CHECKROOM (NCS HFGCS) broadcasting
the 30-character EAM AOJBSW.

     11175.0 was active at 0230z with BEATRICE calling and working
CHECKROOM to enter the net at 0233z.

     8992.0 was active at 0250z, 0320z, 0350z, and 0420z with BEATRICE
broadcasting AOJBSW a the TACAMO PAC restoral rebroadcast windows.

Quiet.

     11175.0 was active at 1617z through 0619z with GUIDEPOST (presumed
E6B) calling CHECKROOM. At 1646z GUIDEPOST called TERTIARY. At 1642z
GUIDEPOST (good levels) called BATTLE HYMN (sounds exactly like; 10
characters; ?). No known responses from all.

     11175.0 was active at 1900z with COGNIZANT (sounds like) checking into
the net, maybe in the blind. Not heard again.

     11175.0 was active at 2025z with CHECKROOM broadcasting the
30-character EAM AOAXIG.

2054z+/-: VOLVE 55 AF0467 departed TRAVIS and flew to the Pacific.

     11175.0 and 8992.0 were active at 2108 through 2110z with BEATRICE
(E6B; presumed VOLVE 55) calling and eventually working (11175) CHECKROOM
and entered the net at 2112z

2112z VIOLA 12 AEFFC4 departed PAX RIVER and flew to the Atlantic.

     11175.0 was active at 2140z and 2210z with CURLY TOP (E6B; presumed
VIOLA 12) broadcasting AOAXIG at the TACAMO LANT restoral rebroadcast
windows.

     11175.0 was active at 2246z with CHECKROOM broadcasting the
30-character EAM AO4FXH.

     11175.0 was active at 2253z and 2350z with BEATRICE (TACAMO PAC)
broadcasting AO4FXH; 2253z perhaps a delayed h+50 restoral rebroadcast. It
continued into the new UTC day as MOLASSES at 0020z (and later with a new
string at 0220z and 0250z while returning to the  California  coast - where
he may have been refuelled by TAHOE 41 and going "dark" after that).

     22.7 KHz VLF FSK was active at 2256z with AO4FXH. TACAMO PAC.

     11175.0 was active at 2257z with BEATRICE calling CHECKROOM
(apparently in the blind; simulcasting): "Break - my station acknowledges
receipt of the following traffic: AO4FXH;" repeat; out.

     11175.0 was active at 2300z with CHECKROOM standing by for traffic;
and, dualling with...

     11175.0 was active at 2300z and 2330z (and 0000z as ACCUSTOM) with
CONFIDENT (a guess as audio was difficult except at 0000z) broadcasting
AO4FXH at the NCS/ABNCP/Gulf restoral rebroadcast windows. No E6B was
visible on ADSB mapping sites for anything flying to the Gulf (there was a
reservation) or anywhere else. LOOM 10 AE041B (static) departed TINKER at
2347z but did not seem to be involved with this.
