0031z RESECTION (HFGCS; never sounded like "rejection.") with 30-character
EAM 5FO3LM.

RESEMBLE calling and working RESECTION to exit the net.  RESEMBLE most
likely E6 WHISK 70 active on ADSB sites but not heard on HF with
traffic during UTC 29 Jul 24. On approach to Travis when he exited the net.

UTC 07/31/24

0001z SEA WASP (HFGCS newday) standing by for traffic.

0010z SEA WASP with 30 character TQF3BF (lots of "dead air" spots during
transmission; sometimes heard in earlier transmissions of EAMs where the
audio just stops and usually starts later in the string.)

0015z SEA WASP with 44 character TQNOPA.

0019z SEA WASP with repeat of TQF3BF (without problems.)

0031z SEA WASP standing by for traffic.
(No such h+00/h+30 statements from this point.)

0032z LL17 (LIMA LIMA 17; female operator; good/fair levels on Cali sdr;
propagational echo on her audio) calling and raising MAINSAIL for) radio
check.

0047z SEA WASP with 30 character EAM 5FLPSG.

0054z SEA WASP with 30 character EAM 5FXEBF.

0059z SEA WASP with 30 character EAM 5FBQJY
[0103z CURT 80 E6 broke from its "loops and line" North Dakota orbit and
returned to OFFUTT for a short while and then repositioned to TINKER.. No
known HF message traffic activity.]

0238z SEA WASP with 30-character EAM 5FZUBX.

0250z COCK FIGHT ( TACAMO PAC; Probably newday callword for RESEMBLE/ABASK
76 E6 who eventually entered an orbit over the Pacific at around 0207z 31
Jul) with 5FZUBX H+20/50 restoral transmission.

0305z SEA WASP with 5FZUBX restoral repeat transmission (not at h+00.)

0320z Nothing heard but probably missed it on 8992.
0350z COCK FIGHT with 5FZUBX (8992 good on Cali sdr; weak/readable on 8992
Ohio Valley sdr.)
0420z COCK FIGHT 5FZUBX 8992.0 West Coast and Ohio Valley sdrs.
(That's probably it as ABASK 76 is out of his orbit and descending into
TRAVIS at this time.)

That "standing by for traffic" activity on the HFGCS lasted for at least
9.5 hours.  The last known instance of such lengthy h+00/h+30 "SBFT" HFGCS
activity was UTC 27 Jun 24 beginning at 0030z and apparently ending at
0730z (without message traffic [with one early exception] during the event.)
