Ends (or too faint to see) by about 0925 LST. This coincides in time with narrow rfi at 1340 MHz. - major GPS: very strong GPS at 1381 MHz ends by 1017 LST. This is scheduled GPS -- see GPS alert for 2007 March 6,7,8. Some GPS during cals. - FAA radars still very quiet at 1350 MHz, seem a bit stronger at end of run compared with beginning. - Beam 1B off. - TOGS run at end only, as scheduled. - Power levels ok all night. - The messages below received during drifts (on 7th) 0003, 0005, 0006, 0009, 0012, 0013, 0015, 0016 WAPPDATA-queue_agcdata: WARNING received duplicate AGC-datablock ...
