0055z  22 Jan 26

UTC 21 Jan 26

[0000z+/-: AE9D87 E6B launched from TINKER and few northwest to SPOKANE, WA
(FAIRCHILD).

0032z: CLASSROOM with communications test count.
0033z: CLASSROOM with communications test count.
[USSTRATCOM CP]

[0056z+/-: AFD871 E6B launched from TINKER and repositioned to OFFUTT.]

0113z: MAINSAIL with test count.

0125z: RECTANGLE (presumed E6B; strong levels on California SDR; but might
be AE9D87 with a "late" request) worked BUZZKILL (NCS; fair levels on SDR)
to eventually enter the net. Achieving connectivity took some time.
0135z: RECTANGLE entered the net.

[Common 0300z+ message traffic window.]

0341z: RECTANGLE (possibly AE9D87 descending toward SPOKANE at this time)
simulcasting, worked BUZZKILL on 11175.0 to exit the net. They seemed to
lose connectivity on and off.

0345z: BUZZKILL; U3FSPF; heard weak on 8992 only; suspected echo
rebroadcast.

0345z: BUZZKILL with test count 8992.0. Weak.

0347z: RECTANGLE with challenge response but went quiet with nothing final
heard on exit point.

0504z: BOMBER RADIO MAINTENANCE raised MAINSAIL for a radio check.

[1425z+/-: AE7DE7 E6B launched from TINKER to New England, then made a
U-turn and returned to TINKER.  No backend callword logged.]

missile fields before returning to OFFUTT.]

[2000z+/-: AE91D2 (previously AE9D87) E6B launched from FAIRCHILD/SPOKANE,
Washington southbound for a holding pattern northwest of FLAGSTAFF, AZ
before entering an apparent refueling run on the AR-233, then turning
westbound before change of UTC new day.]

========

2159z: BUZZKILL (good levels on California SDR) worked AUTOBODY (unheard on
SDR) and apparently confirmed message traffic 7L preamble. Based on time of
transmission it might have been AFD871 visiting missile fields at that
time; otherwise it would probably be AE91D2.

2239z: AC90 (maybe) called ANY RADIO for a signal check.

Quiet.
